REPORT TO COUNCIL
SUBJECT
Action on Amendment No. 1 to the Western Area Power Administration Contract No. 09-SNR-01256 for Displacement of Base Resource to Extend the Agreement Term
BACKGROUND
The California Independent System Operator (CAISO) is one of eight balancing authorities in California who are charged with managing the electrical grid of a specific area. The CAISO controls most of California, and Silicon Valley Power (SVP) is part of the CAISO balancing area.
SVP has been in contract with the Western Area Power Administration (WAPA) since December 2000 for energy deliveries to the City from WAPA's hydroelectric power systems. In 2009, in response to the CAISO’s revised Market Redesign and Technology Upgrade (MRTU) program, the City Council approved and authorized SVP’s participation in WAPA’s Displacement Program through WAPA Contract 09-SNR-01256. The WAPA Displacement Program is a program that allows WAPA Customers in the CAISO area to exchange energy with WAPA Customers outside of the CAISO.
Such exchanges of energy results in fewer electricity import transactions into and out of the CAISO area and cost savings for the customers.
WAPA Contract 09-SNR-01256 is currently set to terminate on December 31, 2024.
DISCUSSION
During the current term of the Displacement Program, the City saved $3.33 million through its participation. However, since 2021, SVP’s participation has been limited for two reasons:
1. The CAISO has discouraged the displacement of energy, especially during a CAISO emergency when imports are short because the Displacement Program is not providing physical energy to the CAISO, but instead pulling energy out of the CAISO.
2. Resource Adequacy (RA) means that a utility has sufficient resources available to serve its electrical demand under all but the most extreme conditions. SVP has an RA commitment and can only displace energy above that commitment. For example, if SVP has an RA commitment of 100 MW and 101 MW is available, then SVP can only displace 1 MW of energy. The opportunity to displace is slim due to the RA commitment.
However, as the energy market continues to change, this program could provide benefits as seen pre -2021. Therefore, staff is recommending extending the agreement for two additional years, terminating on December 31, 2026.
ENVIRONMENTAL REVIEW
City of Santa Clara Printed on 10/20/2023Page 1 of 2

23-1116 Agenda Date: 10/24/2023
This action being considered does not constitute a “project” within the meaning of the California Environmental Quality Act (“CEQA”) pursuant to section 15378(b)(4) of Title 14 of the California Code of Regulations as the amendment is primarily a cost-saving arrangement with no increase to electrical generation. Therefore, the proposed action does not involve any commitment to a specific project which may result in a potentially significant impact on the environment.
FISCAL IMPACT
Over the last five calendar years (2019-2023), participation in the Displacement Program resulted in $1.18 million savings to the City. The amount of savings made to the City each year could change depending on hydro conditions and the amount of energy available for exchange.
COORDINATION
This report has been coordinated with the Finance Department and City Attorney’s Office.

From: John C. Roukema, Director of Electric Utility
Subject: Approval of Western Area Power Administration Contract 09-SNR-01256 for Displacement of Base Resources
EXECUTIVE SUMMARY:
The City of Santa Clara's Electric Utility, Silicon Valley Power (SVP), is requesting approval to enter into an agreement with Western Area Power Administration (Western) to preserve the value and benefits of energy deliveries to the City of Santa Clara from Western's hydroelectric power systems.
The California Independent System Operator (CAISO) implemented its revised Market Redesign and Technology Upgrade (MRTU) on April 1, 2009. As a part of this market redesign, a pricing scheme was implemented which devalues energy deliveries from Western to customers in the CAISO control area, including SVP. The new CAISO pricing scheme will price SVP's Western power deliveries as if they were being delivered at the California-Oregon Border instead of inside of California. This settlement scheme increases the cost of SVP's Western energy deliveries, on average, about $6.00 per MWH, costing the City of Santa Clara an additional $1,000,000 to $2,000,000 per year to serve its customers.
The Displacement Program Agreement allows for an exchange of energy to occur between Western customers located within the Sacramento Municipal Utilities District/Western Control Area and Western customers, like SVP, located within the CAISO Control Area. Such an exchange will result in few transactions at the intertie(s) where the CAISO pricing scheme has been implemented. A copy of Western Area Power Administration Contract 09-SNR-01256 is available for review in the Council offices.
ADVANTAGES AND DISADVANTAGES OF ISSUE:
The benefit to the City from this Displacement Program are derived through partially restoring more accurate pricing for SVP's Western power deliveries and thus reducing the costs for energy deliveries to serve the City. The value created for all parties is then shared among the participating Western Customers inside and outside the CAISO control area.
A minor disadvantage is that there will be more transactions to be tracked and settled among SVP and other Western customers. It is also possible that during very dry years, when hydroelectric power availability is very low, there may not be enough exchange opportunities to cover the administrative costs of the program. However, the participants intend to create a balancing account during wet (high water) years to cover such costs in dry years.

CONTRACT FOR DISPLACEMENT
Do Not Date Here
1. PREAMBLE: This Contract is made this _ ,
2009, pursuant to the Acts of Congress approved June 17, 1902, (32 Stat. 388); August 26, 1937, (50 Stat. 844); August 4, 1939, (53 Stat. 1187); and August 4, 1977, (91 Stat. 565); and Acts amendatory or supplementary to the foregoing Acts; between the UNITED STATES OF AMERICA (United States), acting by and through the Administrator, Western Area Power Administration, Department of Energy, (hereinafter called Western) represented by the officer executing this Contract, or a duly appointed successor, hereinafter called the Contracting Officer, and the Central Valley Project (CVP) preference power customers signing this Contract and set forth in Exhibit A, all collectively called Parties.
2. EXPLANATORY RECITALS:
2.1 Consistent with Western's final 2004 Power Marketing Plan (Marketing Plan), Western provides First Preference Power (FPP) to First Preference Customers under a full requirements contract and a percentage of the Base Resource and Hourly Exchange power (BR) to Central Valley Project (CVP) customers under a base resource contract. First Preference Customers and CVP customers that are not directly connected to Western's transmission system shall be referred to as Non-Direct Connect Customers (NDCC) and they are identified in Exhibit A to this Contract. First Preference Customers and CVP customers that are directly connected to Western's transmission system shall be referred to as Direct Connect Customers (DCC) and they also are identified in Exhibit A to this Contract.
2.2 Western provides power for project purposes (Project Use) prior to marketing power to preference entities. The loads served by Project Use, reside both in and out of the California Independent System Operator Corporation (CAISO) Balancing Authority (BA), and are both non-directly and directly connected to Western's transmission system.
2.3 The Federal Energy Regulatory Commission (FERC) accepted the CAISO's proposed Integrated Balancing Authority Area (IBAA) proposal on September 19, 2008. The CAISO implemented the IBAA proposal simultaneously with the start-up of its Market Redesign and Technology Upgrade (MRTU).
2.4 Under IBAA, imports from the Sacramento Municipal Utility District (SMUD)/Western and Turlock Irrigation District (TID) BAs into the CAISO BA are priced differently than exports from the CAISO BA into the SMUD/Western and TID BAs and therefore could result in adverse financial impacts to both the NDCCs and the DCCs. The Parties believe that the CAISO's discriminatory and arbitrary pricing proposal may expose both the NDCCs and the DCCs to increased financial exposure, unreasonable congestion and loss charges, and unpredictable pricing outcomes. The Parties further believe that the IBAA pricing proposal may have the effect of rendering sales to the CAISO from the SMUD/Western and TID BAs uneconomic in certain circumstances to the ultimate detriment of the Parties' ratepayers.
2.5 The loads that the NDCCs are serving with power received under their full requirements contracts, or base resource contracts are located in the CAISO BA, resulting in the NDCCs incurring charges from the CAISO for imports of FPP and BR into the CAISO BA from the SMUD/Western and TID BAs.
2.6 At times the DCCs export resources out of the CAISO BA into the SMUD/Western and TID BAs, resulting in DCCs incurring charges from the CAISO.
2.7 The NDCCs and the DCCs would like to create a Displacement Program under which the NDCCs FPP or BR would be scheduled to the DCCs in the SMUD/Western and TID BAs, and the DCCs would in turn schedule an equal amount of energy in quality, quantity, and timing to the NDCCs from resources scheduled from or through the CAISO BA.
2.8 Pursuant to the Marketing Plan, Western provides the BR, Optional Purchase, and Custom Products. In light of the CAISO's IBAA program, Western is offering the Displacement Program as a means to continue to fully effectuate its Marketing Plan.
2.9 Western's customers cannot resell federal power provided under Western's contracts without Western's consent. Western supports protecting the value of the FPP and BR and consents to the transactions envisioned by this Displacement Program and is willing to facilitate a Displacement Program of FPP and BR with the NDCCs and the DCCs, subject to the terms and conditions set forth in this Contract.
2.10 The purpose of the Displacement Program is to preserve the benefit of the FPP and BR, create efficiencies, and minimize delivery costs among the NDCCs and the DCCs.
2.11 Although this Contract documents the terms and conditions for a Displacement Program for FPP and BR, it does not preclude the future inclusion of Project Use under the Displacement Program at such time as Western has coordinated with the Bureau of Reclamation and they both have deemed it appropriate for Project Use to be included. The terms and conditions for the inclusion of Project Use would be determined at that time. The objective will be to include Project Use under the existing terms and conditions of this Contract, however there may be a need for modifications to this Contract. In addition, a separate contract may be needed between Western and the Bureau of Reclamation to document the terms and conditions under which Project Use would be included in the Displacement Program.
3. AGREEMENT:
The Parties agree to the terms and conditions set forth herein.
4. EFFECTIVE DATE AND TERM OF CONTRACT:
4.1 This Contract shall become effective on the first day Western designates, and shall remain in effect until midnight of December 31, 2024, subject to prior ///
///
Termination, as otherwise provided for herein. All requirements set forth in Sections 4.1.1 and 4.1.4 herein must be met prior to this Contract becoming effective.
4.1.1 The Displacement Program Administrator Contract has been executed by the CVP Corporation, Western, and at least one DCC and one NDCC, and if required by the terms of Section 6 of the Displacement Program Administrator Contract such DCC and NDCC have paid their $3,400.00 payment to CVP Corporation.
4.1.2 The Displacement Scheduling Aggregator Contract between the CVP Corporation and the Displacement Scheduling Aggregator has been executed by the CVP Corporation and the Displacement Scheduling Aggregator.
4.1.3 The Displacement Scheduling Coordinator Contract (Exhibit C to Contract 03-SNR-00583) has been executed by the CVP Corporation and Western, and the funds advanced by each DCC and NDCC to the CVP Corporation under Section 4.1.1 above have been sent to Western to establish the trust account required under Exhibit C to Contract 03-SNR- 00583.
4.1.4 The Displacement Program Billing Agent Contract has been executed by the CVP Corporation and the Displacement Program billing agent.
4.2 The Parties agree that only with Western's consent any CVP Customer or First Preference Customer, or Project Use customer not currently a party to this Contract may execute this Contract and begin participating in the Displacement Program. Western may add such additional customers at any time during this Contract. Such participation by such additional customers would begin as soon as: (1) the appropriate system changes are made by Western; (2) Western coordinates with the Displacement Program Aggregator to test for and verify proper data exchange between the Parties; and (3) Western issues a revised Exhibit A to all Parties to this Contract. This process is expected to take up to seven (7) business days after execution of this Contract by any new customer.
4.3 At any time during the term of this Contract, any individual NDCC or DCC, or Western acting on behalf of the DCCs and/or NDCCs it represents under this Contract may terminate its participation under this Contract for any reason upon twenty-eight (28) calendar days advance written notice to all other Parties. Such termination shall be effective no earlier than the first day of the calendar month that falls at least 28 calendar days after such notification is provided. After a NDCC or a DCC has requested termination of its participation, Western will modify Exhibit A as appropriate to remove such NDCC or DCC.
4.4 The Parties agree that Western shall have the right to make unilateral changes to Exhibit A to reflect the current Parties to the Contract.
4.5 Each time a revision is made to Exhibit A, Western will also issue an authenticated copy of Exhibit A to the Displacement Program Administrator and the Displacement Scheduling Aggregator listed in Exhibit C to the Contract.
4.6 This Contract will remain in effect as long as there is at least one NDCC and one DCC listed in Exhibit A, unless terminated earlier by Western in accordance with Section 4.7.
4.7 Western, on behalf of itself, may terminate the Displacement Program for any reason by providing thirty (30) calendar days advance written notice to the other Parties to this Contract. Such termination shall be effective no earlier than the first day of the calendar month that falls at least 30 calendar days after such notification is provided. Termination by Western of this Contract terminates Western's consent for displacement and no further displacements under this Contract may take place after the date of termination.
4.8 All obligations incurred hereunder by any individual DCC, NDCC, or Western acting on behalf of the NDCCs and/or DCCs it represents under this Contract shall be preserved until satisfied.
5. DEFINITION OF TERMS:
Unless defined in Section 5 of this Contract or defined elsewhere in this Contract, all terms used in this Contract with initial capitalization shall have the same meaning as those contained in the Master Definitions Supplement of the CAISO Tariff. In addition, as used herein, the following terms whether singular or plural, or used with or without initial capitalization, shall have the following meanings:
5.1 "Base Resource" means CVP and Washoe Project power output, as determined by Western to be available for marketing, after (1) meeting the requirements of Project Use and First Preference Customers, and (2) any other adjustments required for maintenance, regulation, reserves, transformation losses, and ancillary services. For the purpose of this Contract BR shall also include energy from the Hourly Exchange Program.
5.2 "CAISO" means the California Independent System Operator Corporation or its successor.
///
5.3 "Displacement Program" means the program developed by Western, the NDCCs and DCCs and documented in this Contract to provide for the displacement of BR, FPP and Project Use.
5.4 "Displacement Program Administrator" means the entity responsible for administering the Displacement Program.
5.5 "Displacement Program Administrator Contract" means the contract which outlines the responsibilities of the Displacement Program Administrator and also defines the cost responsibilities of the NDCCs and the DCCs related to the costs associated with the Displacement Program. All Parties to this Contract as well as the Displacement Program Administrator will execute the Displacement Program Administrator Contract.
5.6 "Displacement Scheduling Aggregator" means the entity that has contracted with the Displacement Program Administrator to perform the duties related to determining allocation of costs and benefits among the Parties to this Contract related to the Displacement Program.
5.7 "First Preference Customer" means a customer or preference-qualified entity located within Trinity, Calaveras, or Tuolumne Counties, California, as specified under the Trinity River Division Act (69 Stat. 719) and the New Melones provisions of the Flood Control Act of 1962 (76 Stat. 1173, 1191 -1192).
5.8 "First Preference Power" means capacity and energy available under a First Preference Customer entitlement, which is the sum of 1) CVP generation, including energy exchanges with other entities; and 2) purchases made to meet the combined Project Use and First Preference Customer loads.
5.9 "Hourly Exchange Program" means the program in which all Base Resource energy in excess of a CVP customer's load is retained by Western and offered by Western for sale to other CVP customers.
5.10 "Marketing Plan" means Western's 2004 Power Marketing Plan for the Sierra Nevada Region.
5.11 "Project Use" means the power used to operate CVP and Washoe Project facilities in accordance with authorized purposes and pursuant to Reclamation Law.
6. DISPLACEMENT PROGRAM PRINCIPLES:
6.1 In executing transactions related to the Displacement Program, NDCCs and DCCs shall not encourage or engage in any type of market manipulation, collusion, or other unlawful practices associated with the energy market.
6.2 The Displacement Program is non-discriminatory and open to all CVP and Project Use customers.
6.3 The Displacement Program shall be administered in accordance with sound business management practices and in a financially prudent manner.
6.4 The Displacement Program shall be administered so that it is consistent with the terms and conditions of the "Adjustment of Base Resource Percentage" section of the BR contracts which precludes the resale of Federal power. ///
///
///
6.5 The Displacement Program shall be administered so that it ensures that both NDCCs and DCCs get the physical benefit associated with their FPP or BR allocation or their Project Use.
6.6 The intent of the Parties is to share benefits evenly (50/50) between the NDCCs and the DCCs, recognizing that the sharing methodology may not always result in a perfect 50/50 sharing. If the benefit sharing becomes significantly disproportionate to one Party or one class of Parties, the Parties will revise the settlements and scheduling processes on a prospective basis using the procedure identified in Exhibit D.
6.7 The Displacement Program is not intended to shift or increase any Party's costs.
6.8 Nothing in this Contract alters the rights, obligations or duties of the Parties under their BR or FPP Contracts. All Parties shall continue to pay their BR or FPP percentage share of Western's costs, as set forth in each of their respective BR or FPP contracts regardless of BR and FPP quantities participating in the Displacement Program.
6.9 The administration and sharing of benefits arising from the implementation of the Displacement Program shall treat all Parties fairly.
6.10 DCCs shall not take more FPP, BR, or Project Use under the Displacement Program than their available loads consistent with the terms and conditions of the "Electric Service Furnished by Western" section of the BR contracts.
6.11 The environmental attributes (which can include but is not necessarily limited to: carbon dioxide emissions and renewable power attributes) of all resources used for the Displacement Program by the Parties shall remain with the Parties originally contracting for said resources.
6.12 The Displacement Program is intended to be structured like an energy exchange. The Parties recognize, however, that the CAISO's MRTU does not have mechanisms allowing for classic energy exchanges because of the Day- Ahead and Real-Time energy market structures developed by the CAISO whereby the CAISO becomes the
de facto purchaser of energy injections into
and within the CAISO BA, and the de facto seller of energy to all loads within and exports from the CAISO BA.

9. ENFORCEABILITY:
It is not the intent of the Parties that this Contract confer any rights on third parties to enforce the provisions of this Contract except as required by law or express provision in this Contract. Except as provided in this Section 9, this Contract may be enforced, or caused to be enforced, only by Western, the NDCCs, and the DCCs, or their successors or assigns.
10. GENERAL PROVISIONS:
10.1 Integration: This Contract constitutes the entire agreement among the Parties with reference to the subject matter hereof, and supersedes all prior and contemporaneous understandings or agreements, oral or written, among the Parties with respect to the subject matter of this Contract. There are no other agreements, representations, warranties, or covenants, which constitute any part of the consideration for or any condition to, any Party's compliance with its obligations under this Contract.
10.2 Waiver of Consequential Damages: No Party hereunder shall be liable for special, incidental, exemplary, indirect or consequential damages, whether based on contract or tort (including such Party's own negligence) and including, but not limited to, loss of profits or revenue, loss of use of the equipment or any associated equipment, cost of capital, cost of purchased power, cost of substitute equipment, facilities or services, downtime costs, or claims of customers of either Party for such damages, (including intentional action, willful action, gross or ordinary negligence, or force majeure); provided, however, that a Party may seek equitable or other non-monetary relief as may be necessary to enforce this Contract and that damages for which a Party may be liable to another Party under another agreement will not be considered damages under this Contract.
10.3 Notices: Any notice, demand, or request in accordance with this Contract, unless otherwise provided in this Contract, shall be in writing and shall be deemed properly served, given, or made if delivered in person or sent by first class United States mail, postage prepaid, by confirmed electronic facsimile or by prepaid commercial courier service to a Party via its signatory to the Contract, or a Party's successor in that position, at the addresses used in this Contract. Any Party may at any time change the designation or address of a person specified for purposes of written notice. Such a change shall not constitute an amendment to this Contract.
10.4 Uncontrollable Forces: No Party shall be considered to be in default in respect to any obligation hereunder if prevented from fulfilling such obligation by reason of Uncontrollable Force. The term "Uncontrollable Force" for the purpose of this Contract shall mean any cause beyond the control of the Party affected, including but not limited to flood, earthquake, storm, lightning, fire, epidemic, war, riot, civil disturbance, labor disturbance, sabotage, and restraint by court or public authority, which Uncontrollable Forces, by exercise of due diligence and foresight, such Party could not reasonably have been expected to avoid. The Party rendered unable to fulfill any obligation by reason of Uncontrollable Force shall exercise commercially reasonable efforts to remove such inability with all reasonable dispatch.
10.5 Waiver: The failure of a Party to this Contract to insist, on any occasion, upon strict performance of any provision of this Contract will not be considered a waiver of any obligation, right, or duty of, or imposed upon, such Party. Any waiver at any time by a Party of its rights with respect to this Contract shall not be deemed a continuing waiver or a waiver with respect to any other failure to comply with any other obligation, right, or duty of this Contract. Any waivers at any time by any Party of its rights with respect to any default under this Contract, or with respect to any other matter arising in connection with this Contract, shall not constitute or be deemed a waiver with respect to any subsequent default or other matter arising in connection with this Contract. Any delay, short of the statutory period of limitations, in asserting or enforcing any right under this Contract shall not constitute or be deemed a waiver of such right.
10.6 Legal Representation and Fees: Western may be required to provide legal representation and/or pay for any costs (including judgments) related to legal or regulatory proceedings related to the Displacement Program. The customers participating in the Displacement Program during the time frame associated with any legal or regulatory proceeding, agree to pay Western its legal fees and costs (including any judgment against Western) on a pro rata share based on each party's respective liability or responsibility calculated as that party's megawatthours of participation during the time frame associated with the legal or regulatory proceeding.
10.7 Contingent Upon Appropriations and Authorization: Where activities provided for in the Contract extend beyond the current fiscal year, continued expenditures by the Western are contingent upon Congress making the necessary appropriations required for the continued performance of Western's obligations under the Contract. In case such appropriation is not made, the NDCCs and DCCs hereby release Western from its contractual obligations and from all liability due to the failure of Congress to make such appropriation.
10.8 Covenant Against Contingent Fees: The NDCCs and DCCs warrant that no person or selling agency has been employed or retained to solicit or secure the Contract upon an agreement or understanding for a commission, percentage, brokerage, or contingent fee, excepting bona fide employees or bona fide established commercial or selling agencies maintained by the NDCCs and DCCs for the purpose of securing business. For breach or violation of this warranty, Western shall have the right to annul the Contract without liability or in its discretion to deduct from the Contract price or consideration the full amount of such commission, percentage, brokerage, or contingent fee.
10.9 Contract Work Hours and Safety Standards: The Contract, to the extent that it is of a character specified in Section 103 of the Contract Work Hours and Safety Standards Act (Act), 40 U.S.C. § 3701, as amended or supplemented, is subject to the provisions of the Act, 40 U.S.C. §§ 3701-3708, as amended or supplemented, and to regulations promulgated by the Secretary of Labor pursuant to the Act.

Power & Water Resources Pooling Authority
Resolution 09-05-05
RESOLUTION AUTHORIZING AND DIRECTING THE GENERAL MANAGER TO
ENTER INTO CONTRACTS ENABLING THE DISPLACEMENT OF CENTRAL
VALLEY PROJECT BASE RESOURCE ALLOCATIONS FOR THE PURPOSE OF
ACHIEVING EFFICIENCIES AND MINIMIZING DELIVERY COSTS
WHEREAS, the Power and Water Resources Pooling Authority (Pooling Authority) was created by a Joint Powers Agreement to, among other things, study, promote, develop, conduct, finance, acquire, construct, and/or operate water and energy-related projects and programs; and
WHEREAS, the Pooling Authority Parties and Stakeholders, as defined in the Joint Powers Agreement, have signed an Aggregation Services Agreement ("ASA") under which the Authority provides aggregated electric services to electric accounts designated by Parties and Stakeholders that are signatories to the ASA ("Project Participants"), and WHEREAS, the Western Area Power Administration ("Western") markets the surplus generation from the Central Valley Project pursuant to its 2004 Power Marketing Plan ("Marketing Plan"); and
WHEREAS, pursuant to the Marketing Plan, Western executed Base Resource Contract 04-SNR-00722 ("Base Resource Contract") with the Pooling Authority on August 12, 2004; and WHEREAS, the Pooling Authority executed a Membership Agreement with the Central Valley Project Corporation ("CVP Corp") in August 2008; and WHEREAS, certain Base Resource customers are not directly connected to Western's transmission system ("NDCCs") and other Base Resource customers are directly connected to Western's transmission system ("DCCs"); and
WHEREAS, all Pooling Authority Project Participants are NDCCs except Byron-Bethany Irrigation District which is a DCC; and
WHEREAS, the Federal Energy Regulatory Commission conditionally approved the Integrated Balancing Authority Area ("IBAA") proposal of the California Independent System operator ("CAISO") on September 19, 2008 such that the CAISO implemented the IBAA proposal simultaneously with the start-up of its Market Redesign and Technology Upgrade ("MRTU"); and
WHEREAS, implementation of IBAA could result in adverse financial impacts to both the NDCCs and the DCCs because imports from the Sacramento Municipal Utility District ("SMUD")/Western and Turlock Irrigation District ("TID") Balancing Authorities ("BAs") to the CAISO BA are priced differently than exports from the CAISO BA into the SMUD/Western and TID BAs; and
WHEREAS, the NDCCs and DCCs believe that the CAISO's MRTU pricing proposal may expose them to increased financial exposure, unreasonable congestion and loss charges, and unpredictable pricing outcomes as well as have the effect of causing sales to the CAISO 1 of 33
from the SMUD/Western and TID BAs to be uneconomic in certain circumstances to the ultimate detriment of the NDCC and DCC ratepayers; and
WHEREAS, the loads that the NDCCs are serving with power received under their Base Resource Contracts incur charges from the CAISO for imports from the SMUD/Western and TID Bas and at times the DCCs export resources out of the CAISO BA into the SMUD/Western and TID BAs, resulting in DCCs incurring charges from the CAISO; and WHEREAS, the NDCCs and the DCCs seek to create a Displacement Program under which the NDCCs Base Resource can be scheduled to the DCCs in the SMUD/Western and TID BAs, and the DCCs in turn can schedule an equal amount of energy in quality, quantity, and timing to the NDCCs from resources scheduled from or through the CAISO BA; and WHEREAS, in consideration of the CAISO's IBAA program, Western is offering the Displacement Program through Contract 09-SNR-01256 ("Displacement Contract") as a means to continue to fulfill the intent of the 2004 Power Marketing Plan; and WHEREAS, the CVP Corp has agreed to be the Displacement Program Administrator as described in the Displacement Contract; and
WHEREAS, the CVP Corp will contract with a Displacement Scheduling Aggregator who will be responsible for scheduling the displaced Base Resource energy between DCCs and NDCCs on an hourly basis, calculating the savings statements, and preparing corresponding financial reports which will be used as input for invoicing; and WHEREAS, the CVP Corp will contract with a Scheduling Coordinator which will schedule the trades between the DCCs and NDCCs to the CAISO; and WHEREAS, the CVP Corp will contract with a Billing Agent to collect and make payments to and from the participants as calculated by the Displacement Scheduling Aggregator and collect fees from the participants to make payments for the service contracts required to enable the displacement transactions; and
WHEREAS, the CVP Corp Participant Exhibit C establishes the repayment mechanisms necessary to pay for the program costs incurred by CVP Corp in performing its administrative responsibilities.
NOW, THEREFORE, BE IT RESOLVED that the Pooling Authority Board of Directors hereby:
1. Finds that it is reasonable and consistent with the purpose and objective of the ASA for the Pooling Authority to participate in the Displacement Program which is being established to preserve the value and benefit of the Pooling Authority's Base Resource allocations, create efficiencies amongst Central Valley Project customers, and minimize delivery costs among the Non-Direct Connect Customers and the Direct Connect Customers.
2. Authorizes the General Manager to execute and implement the Displacement Contract, attached as Exhibit A to this Resolution, and the Participant Exhibit C Agreement, attached as Exhibit B to this Resolution, with the prior approval of General Counsel as to the form of the final, executable versions.
2 of 33
3. Authorizes this Resolution to take effect immediately upon its adoption.

r 2009, by the following vote on roll call:
EXHIBIT A
(List of Customers Participating in Displacement Program)

Dear Mr. Roukema:
The Western Area Power Administration (Western) and the City of Santa Clara, Silicon Valley Power (SVP) are parties to Contract 09-SNR-01256 (Contract). This Contract provides for SVP’s participation in Western’s Base Resource Displacement Program (DP).
In anticipation of the start of the DP this year,
Western revised Exhibit A, Attachment 1 to Exhibit
B, and Exhibit D, to the Contract. Western revised Exhibit A to change the pricing point for some of the participants to reflect the California Independent System Operator’s (CAISO) Market Efficiency Enhancement Agreement pricing. Attachment 1 was revised to include the most current CAISO charges that make up the avoided fixed transaction costs related to the DP. The CAISO’s Charge Code 6496 (Peak Reliability Coordinator Charge) was also added to the table as an additional fixed transaction charge. Exhibit D was revised to update the DP working group representatives.
Enclosed for your records are Exhibit A, Revision 9, Attachment 1, Revision 28 to Exhibit B, and Exhibit D, Revision 8, to the Contract. If you have any questions, please contact Mr. Hiroshi Kashiwagi of my staff at (916) 353-4477 or [email protected].
EXHIBIT A
(List of Customers Participating in Displacement Program)
1. This Exhibit A, Revision 9 to be effective under and as a part of Contract 09-SNR-01256 (Contract) shall become effective on April 1, 2016; and shall remain in effect until either superseded by another Exhibit A or termination of the Contract.
2. Western will unilaterally revise this Exhibit A, as needed, to reflect those customers who become signatories to this Contract. The Parties agree that they have granted Western the right to make unilateral changes to Exhibit A in accordance with the terms and conditions agreed to by the Parties and set forth in Section 11 of the Contract. Each time a revision is made to this Exhibit A, Western will issue an authenticated copy of the revised exhibit to all Parties to this Contract.
2.1 The following customers have signed the Contract:
Exhibit B
(Settlements and Shared Savings Methodology)
1. This Exhibit B, to be effective under and as a part of Contract 09-SNR-01256 (Contract) shall become effective upon execution of the Contract; and shall remain in effect until either superseded by another Exhibit B or termination of the Contract.
2. Western will revise this Exhibit B, as needed, in accordance with the procedures set forth in Exhibit D to this Contract. The Parties agree that they have granted Western the right to make unilateral changes to Exhibit B in accordance with the terms and conditions agreed to by the Parties and set forth in Section 11 of the Contract. Each time a revision is made to this Exhibit B Western will issue an authenticated copy of the revised exhibit to all Parties to this Contract.
3. This Exhibit B describes the steps for Settlements under the Displacement Program and the methodology to compute the net savings (or costs) of the Displacement Program and determines payments between the NDCCs and the DCCs to share the savings (or costs). Any expression in this Exhibit B preceded by the equals sign ("=") is a mathematical formula, and the following symbols in any such expression mean:
"x" is the mathematical operator for multiplication.
"/" is the mathematical operator for division
"+" is the mathematical operator for addition
"-" is the mathematical operator for subtraction, and when preceding a number or a variable may also mean the negative value of that number or variable.
4. Shared Savings Calculations:
The net savings (or net cost) realized through the Contract will be shared using the following methodology:
4.1 Assumptions:
4.1.1 The fundamental premise of the Displacement Program is that by executing transactions envisioned under the Displacement Program, the following two benefits occur:
1. The DCCs avoid the transaction costs associated with exporting power from the CAISO; and
2. Both DCCs and NDCCs receive a benefit of the pricing difference between the IBAA export prices that DCCs pay the CAISO for their exports, and the IBAA import prices that the NDCCs get paid by the CAISO for their BR, FPP, and Project Use (PU) imports into the CAISO, during periods when the IBAA export price exceeds the IBAA import price.
4.1.2 The transactions associated with the Displacement Program will generally be structured so that DCCs make NDCCs whole for benefits lost as a result of reduced or eliminated imports of BR, FPP and PU due to Displacement Program transactions. These benefits include payment by the DCCs to NDCCs for the ancillary services currently available from imports of BR, FPP, and PU firm power schedules. Integrated Forward Market (IFM) Load Uplift Obligation Inter-SC trades from NDCCs to DCCs provide the benefit that NDCCs would have realized with the import of BR, FPP, and PU firm power schedules. The payment of the energy cost component of the Displacement Program transactions will be accomplished by an Inter SC Trade at the NP15 EZ Gen Trading Hub.
Each Party will bear the costs of Inter-SC Trade transaction costs associated with Displacement Program transactions.
4.1.3 The benefits from this transaction are avoided DCC transaction costs plus the spread between the locational marginal prices (LMP) received by NDCCs for imports of BR, FPP, or PU into the CAISO and the LMPs paid by DCCs for the export of power from the CAISO. The shared savings will be structured into a payment based on the sharing of the transaction costs that the DCCs avoid by taking displacement energy, plus the sharing of the spread between the LMP for IBAA exports and the LMP for IBAA imports. The benefit of the transactions associated with the Displacement Program will be split equally between the NDCCs and the DCCs.
4.2 Avoided Transaction Cost Determination:
The following table shows the CAISO scheduling charges and their associated charge codes that will be used in the avoided transaction cost determination.
They represent the CAISO charges associated with exports avoided by the DCCs when Displacement Program transactions occur:
Table B-1
Components of the Avoided Transaction Costs
* Fixed charges may be changed from time to time by the CAISO, as implemented by CAISO tariff changes and notices to market participants.
To determine the shared savings for the Avoided Transaction Costs, the total Avoided Fixed Charges in Table B-1 will be added to the sum of Avoided Variable Charges in Table B-1 (as they appear in actual settlement statements), and then divided by two. The result will be the shared Avoided Transaction Costs which will result in a payment from DCCs to NDCCs for each MWh of displacement energy
Shared Avoided Transaction Costs
= Avoided Fixed Transaction Costs + Avoided Variable Transaction Costs 2 At any time that Western is notified that the charges associated with the Fixed Charges identified in Table B-1 above are revised, Western will revise this Exhibit B to reflect the updated charges and will issue a revised Exhibit B. The effective date of the revised Exhibit B will be the effective date of the updated charge.
4.3 Shared LMP Spread Savings Rate:
The variable shared savings is based upon a sharing of the difference between the LMPs received by NDCCs for imports of BR, FPP, or PU into the CAISO (based upon the NDCC-specific LMP), and the LMPs paid by DCCs for export of power from the CAISO (based upon the DCC-specific LMP). For the examples in this Section 4 regarding the sharing of the difference in import and export LMPs, it is assumed that all DCCs and NDCCs either have the same export LMP, or the same import LMP. Under IBAA as implemented by the CAISO, any DCC's or NDCC's import LMP or export LMP will vary, based upon the location used for scheduling the import into the CAISO or export out of the CAISO. Details on how to treat varying LMPs are set forth in the Settlements Section of this Exhibit B.
For this Section 4.3, variables shown in the formulae are as follows.
DCCExp = the LMP paid by DCCs for export of power from the CAISO NDCCImp = the LMP received by NDCCs for imports of BR, FPP, or PU into the CAISO
FTHub = the Financial Trading Hub LMP (at NP15 EZ Gen Trading Hub) Total LMP Benefit:
= DCCExp-NDCCImp
4.3.1 DCCs will execute Inter-SC Trades with the NDCCs at one (or more) of the financial trading hubs in order to settle the transaction between them (see Exhibit C). The Parties agree to use the NP15 EZ Gen Trading Hub for the financial trading hub transactions. The use of Inter-SC Trade transactions at the NP15 EZ Gen Trading Hub results in LMP Benefit to the Parties as follows:
NDCC Spread:
= FTHub -NDCCImp
DCC Spread:
= DCCExp-FTHub
4.3.2 With the allocation of the LMP benefit spread using the formula above, the formula for the shared LMP benefit can be expressed as follows: Determine the shared Spread Benefits by dividing the sum of the NDCC Spread and the DCC Spread from 4.3.1 in half.
Shared Benefit:
= 0.5 x (NDCC Spread +DCC Spread)
4.3.3 From the perspective of the NDCCs, they will have to share their net benefit by returning to the DCCs one half of the difference between their NDCC Spread Benefit and the Shared Benefit in accordance with the 50/50 rule. This can be expressed in the following formula:
Payment from NDCCs to DCCs:
= NDCC Spread -[0.5 x (NDCC Spread+DCC Spread)]
Inserting the LMP formulae from Step 4.3.1 above, the Payment formula can be expressed as follows:
Payment from NDCCs to DCCs:
= (FTHub - IBAA lmp )-[0.5x ([FTHub - IBAA lmp]+ [iBAAExp - FTHub])] The formula can be reduced for terms that can be combined or that cancel each other. Here are the reducing steps and the resulting simplified Payment formula:
Payment rate from NDCCs to DCCs ($/MWh of displaced energy):
= (FTHub - IBAA Imp) -[0.5 x (IBAAExp - IBAA Imp)]
= (FTHub - IBAA Imp) + [0.5 x (IBAA Imp- IBAAExp)]
= FTHub -[0.5 x ( IBAA lmp + IBAAExp)]
Positive amounts represent sums owed by the NDCCs to the DCCs.
4.4 Value of Ancillary Services:
Rather than execute Inter-SC Trades to transfer the DCCs avoided ancillary services obligations to the NDCCs (which lose the ancillary services credit by not scheduling BR or FPP as an import into the CAISO), the Parties have elected to settle the ancillary services financially, with a payment from the DCCs to the NDCCs.
For this Section 4.4, variables shown in the formulae are as follows:
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The payment rate for the value of the spinning and non-spinning reserves associated with the displacement transactions will be determined by the following formula:
Ancillary Services Rate for Payment from DCCs to NDCCs
= 0.035 x Spin + 0.035 x NonSpin
4.5 Total Shared Savings:
The Total Shared Savings is determined by subtracting the Fixed Shared Savings Payment from the Variable Shared Savings Payment:
Total Shared Savings:
= Shared Spread Savings - Shared Avoided Transaction Costs - Ancillary Services
Positive Total Shared Savings indicates payments are made from NDCCs to DCCs. Negative Total Shared Savings indicates payments are made from DCCs to NDCCs.
5. Settlements:
The following process will be used for settling payments between the DCCs and NDCCs and for collecting Displacement Program administrative costs from the Parties.
5.1 For settlements between the Parties, the Parties will use the Displacement Program Administrator as the settlements agent.
5.2 The Billing Period will be by calendar month. All Shared Savings Payments during any Billing Period due from or to any Party will be summed for the Billing Period such that the Party makes or receives one payment for the settlement of the Shared Savings Payments.
5.2.1 Hourly settlement information for the LMP spreads will be finalized after the CAISO has published the final LMPs. Preliminary settlement information can be provided prior to finalization. The Shared Savings Settlements can be provided on the following schedule:
Initial settlement information: After close of IFM and upon publishing of LMPs by CAISO
Final settlement information: T + 8 days, based upon publishing of final LMPs by CAISO
5.3 Displacement Program Administrative costs will be added (or netted against) into any Party's Shared Savings Payments due or payable. Recovery of the Displacement Program Administrative costs shall be in accordance with the terms and conditions outlined in the Displacement Program Administrator Contract. In general, the administrative costs will be allocated 50/50 to DCCs and NDCCs.
5.4 The settlement process shall be structured such that any Party will either make a single payment to the Displacement Program Administrator or receive a single payment from the Displacement Program Administrator for its sharing of the benefits and costs of participation in the Displacement Program for any given billing period.
5.5 Settlement of the Avoided Transaction Savings: Eighteen (18) charge code types determine the Avoided Transaction Costs when DCCs schedule in lieu of exporting from the CAISO. Table B-1 shows the charge codes that will be used for settling the shared Avoided Transaction Costs between the Displacement Program Participants. The rates associated with the first three (3) charge codes on the list are determined by tariff, and remain fixed until the CAISO files a tariff change and issues a notice to market participants. The other charge types are all determined in the settlements process, and are not known in advance. For purposes of settlements for the Displacement Program, the values for these charges will be obtained from actual settlement statements of one (1) or more NDCCs.
For this Section 5.5, variables shown in the formulae are as follows.
CAISO Chargei = Charge type i from Table B-1 where i is the index number of the charge type listing in the table, from 1 to 18.
j = the total number of charge types used in the shared avoided transaction cost calculation, currently 18.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
The shared avoided transaction payment made by DCC d is calculated as follows:
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the Avoided Transaction Costs payment.
The shared avoided transaction payment received by NDCC n is calculated as follows:
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared Avoided Transaction Costs payment.
5.6 Settlement of the Shared LMP Spread Benefit. Because the LMPs that apply for the variable savings calculation described in Section 4 above will vary based upon where a Party schedules an import in to or an export out of the CAISO, any single Party that is in either the NDCC or DCC class will settle the LMP portion of the variable shared savings by comparing the LMP of their avoided scheduling point, with the weighted average LMP calculated for avoided transactions incurred by the other class of Party taking part in Displacement in any given hour.
For this Section 5.6, variables shown in the formulae are as follows.
DCCExpd = the avoided export LMP for DCC d in the given hour, where d indexes from 1 up to the total number of participating DCCs.
DCCExpave = the weighted average avoided export LMP for all DCCs.
NDCCImpn = the avoided import LMP for NDCC n in the given hour where n indexes from 1 up to the total number of participating NDCCs.
NDCCImpave = the weighted average avoided import LMP for all NDCCs.
N = total number of NDCC Displacement Program participants.
D = total number of DCC Displacement Program participants.
FTHub = the Financial Trading Hub LMP.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
5.6.1 Determine the weighted average LMPs for NDCCs and DCCs based upon the actual Displacement Program transactions for the hour.
5.6.2 Determine the shared savings amount owing from or to be paid to the Displacement Program Administrator.
The LMP portion of variable shared savings payment owed to, or to be received from the Displacement Program Administrator by NDCC n is:
Variable shared saving payment made by NDCC n
= Qn x [FTHub - 0.5 x ( NDCC Impn + DCCExpave)]
Positive amounts resulting from the formula above represent sums owed by the NDCCs to the Displacement Program Administrator for the variable shared savings component.
THE LMP portion of the Variable shared saving payment made by DCC d = Qdx [0.5x( NDCC Impave + DCCExpd)- FTHub]
Positive amounts resulting from the formula above represent sums owed by the DCCs to the Displacement Program Administrator for the variable shared savings component.
Rounding of settlement amounts will occur on total net billing period amounts.
Hourly settlement amounts will not be rounded.
5.7 Settlement for the ancillary service obligation. To settle for the ancillary service credit that the NDCCs lose by avoiding import of BR, FPP, and PU into the CAISO, each DCC will make payment for the ancillary service charges to the Displacement Program Administrator, who will then make payments to each NDCC for the BR, FPP, of PU import that was displaced.
For this section 5.7, variables shown in the formulae are as follows:
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The ancillary services replacement payment made by DCC d is calculated as follows:
Ancillary Services Payment made by DCCs
= Qdx[0.035 x Spin + 0.035 x NonSpin]
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the ancillary services replacement.
The shared ancillary service replacement payment received by NDCC n is calculated as follows:
= - Qnx[0.035 x Spin + 0.035 x NonSpin]
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared avoided transaction costs payment.
5.8 The Parties agree that once Parties' obligations under the Displacement Program for any given month are adjusted following the CAISO Initial Reissue Invoices, there will be no retroactive changes to the charges incurred under this Contract for said month.
5.9 Settlements Timing:
Table B-2 below shows the Displacement Program settlements timeline.
6. Review of Charge Codes: Table B-3 below shows the charge codes that were reviewed for determining their applicability in the shared savings calculations.

(Settlements and Shared Savings Methodology)
1. This Exhibit B, Revision 6, to be effective under and as a part of Contract 09-SNR-01256 (Contract) shall become effective on July 1, 2009; and shall remain in effect until either superseded by another Exhibit B or termination of the Contract.
2. Western will revise this Exhibit B, as needed, in accordance with the procedures set forth in Exhibit D to this Contract. The Parties agree that they have granted Western the right to make unilateral changes to Exhibit B in accordance with the terms and conditions agreed to by the Parties and set forth in Section 11 of the Contract. Each time a revision is made to this Exhibit B Western will issue an original of the revised exhibit to all Parties to this Contract.
3. This Exhibit B describes the steps for Settlements under the Displacement Program and the methodology to compute the net savings (or costs) of the Displacement Program and determines payments between the NDCCs and the DCCs to share the savings (or costs). Any expression in this Exhibit B preceded by the equals sign ("=") is a mathematical formula, and the following symbols in any such expression mean:
"x" is the mathematical operator for multiplication.
"/" is the mathematical operator for division
"+" is the mathematical operator for addition
"-" is the mathematical operator for subtraction, and when preceding a number or a variable may also mean the negative value of that number or variable.
4. Shared Savings Calculations.
The net savings (or net cost) realized through the Contract will be shared using the following methodology:
4.1 Assumptions:
4.1.1 The fundamental premise of the Displacement Program is that by executing transactions envisioned under the Displacement Program, the following two benefits occur:
1. The DCCs avoid the transaction costs associated with exporting power from the CAISO; and
2. Both DCCs and NDCCs receive a benefit of the pricing difference between the IBAA export prices that DCCs pay the CAISO for their exports, and the IBAA import prices that the NDCCs get paid by the CAISO for their BR, FPP, and Project Use (PU) imports into the CAISO, during periods when the IBAA export price exceeds the IBAA import price.
4.1.2 The transactions associated with the Displacement Program will generally be structured so that DCCs make NDCCs whole for benefits lost as a result of reduced or eliminated imports of BR, FPP and PU due to Displacement Program transactions. These benefits include payment by the DCCs to NDCCs for the ancillary services currently available from imports of BR, FPP, and PU firm power schedules. Integrated Forward Market (IFM) Load Uplift Obligation Inter-SC trades from NDCCs to DCCs provide the benefit that NDCCs would have realized with the import of BR, FPP, and PU firm power schedules. The payment of the energy cost component of the Displacement Program transactions will be accomplished by an Inter SC Trade at the NP15 EZ Gen Trading Hub.
Each Party will bear the costs of Inter-SC Trade transaction costs associated with Displacement Program transactions.
4.1.3 The benefits from this transaction are avoided DCC transaction costs plus the spread between the locational marginal prices (LMP) received by NDCCs for imports of BR, FPP, or PU into the CAISO and the LMPs paid by DCCs for the export of power from the CAISO. The shared savings will be structured into a payment based on the sharing of the transaction costs that the DCCs avoid by taking displacement energy, plus the sharing of the spread between the LMP for IBAA exports and the LMP for IBAA imports. The benefit of the transactions associated with the Displacement Program will be split equally between the NDCCs and the DCCs.
4.2 Avoided Transaction Cost Determination:
The following table shows the CAISO scheduling charges and their associated charge codes that will be used in the avoided transaction cost determination.
They represent the CAISO charges associated with exports avoided by the DCCs when Displacement Program transactions occur:
Fixed charges may be changed from time-to-time by the CAISO, as implemented by CAISO tariff changes and notices to market participants.
**These charges will be multiplied by (-1) before using them for the calculations of Variable Avoided Costs.
To determine the shared savings for the Avoided Transaction Costs, the total Avoided Fixed Charges in Table B-1 will be added to the sum of Avoided Variable Charges in Table B-1 (as they appear in actual settlement statements), and then divided by two. The result will be the shared Avoided Transaction Costs which will result in a payment from DCCs to NDCCs for each MWh of displacement energy
At any time that Western is notified that the charges associated with the Fixed Charges identified in Table B-1 above are revised, Western will revise this Exhibit B to reflect the updated charges and will issue a revised Exhibit B. The effective date of the revised Exhibit B will be the effective date of the updated charge.
4.3 Shared LMP Spread Savings Rate:
Table B-1
Components of the Avoided Transaction Costs
The variable shared savings is based upon a sharing of the difference between the LMPs received by NDCCs for imports of BR, FPP, or PU into the CAISO (based upon the NDCC-specific LMP), and the LMPs paid by DCCs for export of power from the CAISO (based upon the DCC-specific LMP). For the examples in this Section 4 regarding the sharing of the difference in import and export LMPs, it is assumed that all DCCs and NDCCs either have the same export LMP, or the same import LMP. Under IBAA as implemented by the CAISO, any DCC's or NDCCs import LMP or export LMP will vary, based upon the location used for scheduling the import into the CAISO or export out of the CAISO. Details on how to treat varying LMPs are set forth in the Settlements Section of this Exhibit B.
For this Section 4.3, variables shown in the formulae are as follows.
DCCExp = the LMP paid by DCCs for export of power from the CAISO NDCCImp = the LMP received by NDCCs for imports of BR, FPP, or PU into the CAISO
FTHub = the Financial Trading Hub LMP (at NP15 EZ Gen Trading Hub) Total LMP Benefit:
= DCCExp-NDCCImp
4.3.1 DCCs will execute Inter-SC Trades with the NDCCs at one (or more) of the financial trading hubs in order to settle the transaction between them (see Exhibit C). The Parties agree to use the NP15 EZ Gen Trading Hub for the financial trading hub transactions. The use of Inter-SC Trade transactions at the NP15 EZ Gen Trading Hub results in LMP Benefit to the Parties as follows:
NDCC Spread:
= FTHub -NDCCImp
DCC Spread:
= DCCExp -FTHub
4.3.2 With the allocation of the LMP benefit spread using the formula above, the formula for the shared LMP benefit can be expressed as follows: Determine the shared Spread Benefits by dividing the sum of the NDCC Spread and the DCC Spread from 4.3.1 in half.
Shared Benefit:
= 0.5 x (NDCC Spread+DCC Spread)
4.3.3 From the perspective of the NDCCs, they will have to share their net benefit by returning to the DCCs one half of the difference between their NDCC Spread Benefit and the Shared Benefit in accordance with the 50/50 rule. This can be expressed in the following formula:
Payment from NDCCs to DCCs:
= NDCC Spread -[0.5 x (NDCC Spread + DCC Spread)]
Inserting the LMP formulae from Step 4.3.1 above, the Payment formula can be expressed as follows:
Payment from NDCCs to DCCs:
= (FTHub - IBAA Imp) -[0.5 x ([FTHub - IBAAImp]+ [iBAAExp - FTHub])] The formula can be reduced for terms that can be combined or that cancel each other. Here are the reducing steps and the resulting simplified Payment formula:
Payment rate from NDCCs to DCCs ($/MWh of displaced energy):
= (FTHub - IBAA Imp) -[0.5 x (IBAAExp - IBAA Imp)]
= (FTHub - IBAA Imp) + [0.5 x (IBAA Imp- IBAAExp)]
= FTHub -[0.5 x ( IBAA lmp + IBAAExp)]
Positive amounts represent sums owed by the NDCCs to the DCCs.
4.4 Value of Ancillary Services:
Rather than execute Inter-SC Trades to transfer the DCC's avoided ancillary services obligations to the NDCCs (which lose the ancillary services credit by not scheduling BR or FPP as an import into the CAISO), the Parties have elected to settle the ancillary services financially, with a payment from the DCCs to the NDCCs.
For this Section 4.4, variables shown in the formulae are as follows:
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The payment rate for the value of the spinning and non-spinning reserves associated with the displacement transactions will be determined by the following formula:
Ancillary Services Rate for Payment from DCCs to NDCCs
= 0.035 x Spin + 0.035 x NonSpin
4.5 Total Shared Savings:
The Total Shared Savings is determined by subtracting the Fixed Shared Savings Payment from the Variable Shared Savings Payment:
Total Shared Savings:
= Shared Spread Savings - Shared Avoided Transaction Costs - Ancillary Services
Positive Total Shared Savings indicates payments are made from NDCCs to DCCs. Negative Total Shared Savings indicates payments are made from DCCs to NDCCs.
5. Settlements:
The following process will be used for settling payments between the DCCs and NDCCs and for collecting Displacement Program administrative costs from the Parties.
5.1 For settlements between the Parties, the Parties will use the Displacement Program Administrator as the settlements agent.
5.2 The Billing Period will be by calendar month. All Shared Savings Payments during any Billing Period due from or to any Party will be summed for the Billing Period such that the Party makes or receives one payment for the settlement of the Shared Savings Payments.
5.2.1 Hourly settlement information for the LMP spreads will be finalized after the CAISO has published the final LMPs. Preliminary settlement information can be provided prior to finalization. The Shared Savings Settlements can be provided on the following schedule:
Initial settlement information: After close of IFM and upon publishing of LMPs by CAISO
Final settlement information: T + 8 days, based upon publishing of final LMPs by CAISO
5.3 Displacement Program Administrative costs will be added (or netted against) into any Party's Shared Savings Payments due or payable. Recovery of the Displacement Program Administrative costs shall be in accordance with the terms and conditions outlined in the Displacement Program Administrator Contract. In general, the administrative costs will be allocated 50/50 to DCCs and NDCCs.
5.4 The settlement process shall be structured such that any Party will either make a single payment to the Displacement Program Administrator or receive a single payment from the Displacement Program Administrator for its sharing of the benefits and costs of participation in the Displacement Program for any given billing period.
5.5 Settlement of the Avoided Transaction Savings: Eighteen (18) charge code types determine the Avoided Transaction Costs when DCCs schedule in lieu of exporting from the CAISO. Table B-1 shows the charge codes that will be used for settling the shared Avoided Transaction Costs between the Displacement Program Participants. The rates associated with the first three (3) charge codes on the list are determined by tariff, and remain fixed until the CAISO files a tariff change and issues a notice to market participants. The other charge types are all determined in the settlements process, and are not known in advance. For purposes of settlements for the Displacement Program, the values for these charges will be obtained from actual settlement statements of one (1) or more NDCCs.
For this Section 5.5, variables shown in the formulae are as follows.
CAISO Chargei = Charge type i from Table B-1 where i is the index number of the charge type listing in the table, from 1 to 18.
j = the total number of charge types used in the shared avoided transaction cost calculation, currently 18.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
The shared avoided transaction payment made by DCC d is calculated as follows:
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the Avoided Transaction Costs payment.
The shared avoided transaction payment received by NDCC n is calculated as follows:
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared Avoided Transaction Costs payment.
5.6 Settlement of the Shared LMP Spread Benefit. Because the LMPs that apply for the variable savings calculation described in Section 4 above will vary based upon where a Party schedules an import in to or an export out of the CAISO, any single Party that is in either the NDCC or DCC class will settle the LMP portion of the variable shared savings by comparing the LMP of their avoided scheduling point, with the weighted average LMP calculated for avoided transactions incurred by the other class of Party taking part in Displacement in any given hour.
For this Section 5.6, variables shown in the formulae are as follows.
DCCExpd = the avoided export LMP for DCC d in the given hour, where d indexes from 1 up to the total number of participating DCCs.
DCCExpave = the weighted average avoided export LMP for all DCCs.
NDCCImpn = the avoided import LMP for NDCC n in the given hour where n indexes from 1 up to the total number of participating NDCCs.
NDCCImpave = the weighted average avoided import LMP for all NDCCs.
N = total number of NDCC Displacement Program participants.
D = total number of DCC Displacement Program participants.
FTHub = the Financial Trading Hub LMP.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
5.6.1 Determine the weighted average LMPs for NDCCs and DCCs based upon the actual Displacement Program transactions for the hour.
5.6.2 Determine the shared savings amount owing from or to be paid to the Displacement Program Administrator.
The LMP portion of variable shared savings payment owed to, or to be received from the Displacement Program Administrator by NDCC n is:
Variable shared saving payment made by NDCC n
= Qn x [FTHub -0.5*(NDCCImpn+ DCCExp ave)]
Positive amounts resulting from the formula above represent sums owed by the NDCCs to the Displacement Program Administrator for the variable shared savings component.
THE LMP portion of the Variable shared saving payment made by DCC d = Qdx [0.5x( NDCC Impave + DCCExpd) - FTHub]
Positive amounts resulting from the formula above represent sums owed by the DCCs to the Displacement Program Administrator for the variable shared savings component.
Rounding of settlement amounts will occur on total net billing period amounts.
Hourly settlement amounts will not be rounded.
5.7 Settlement for the ancillary service obligation. To settle for the ancillary service credit that the NDCCs lose by avoiding import of BR, FPP, and PU into the CAISO, each DCC will make payment for the ancillary service charges to the Displacement Program Administrator, who will then make payments to each NDCC for the BR, FPP, of PU import that was displaced.
For this section 5.7, variables shown in the formulae are as follows:
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The ancillary services replacement payment made by DCC d is calculated as follows:
Ancillary Services Payment made by DCCs
= Qd x[0.035 x Spin + 0.035 x NonSpin]
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the ancillary services replacement.
The shared ancillary service replacement payment received by NDCC n is calculated as follows:
= - Qnx[0.035 x Spin + 0.035 x NonSpin]
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared avoided transaction costs payment.
5.8 The Parties agree that once Parties' obligations under the Displacement Program for any given month are adjusted following the CAISO Initial Reissue Invoices, there will be no retroactive changes to the charges incurred under this Contract for said month.
6. Review of Charge Codes: Table B-3 below shows the charge codes that were reviewed for determining their applicability in the shared savings calculations.

4. Shared Savings Calculations:
The net savings (or net cost) realized through the Contract will be shared using the following methodology:
4.1 Assumptions:
4.1.1 The fundamental premise of the Displacement Program is that by executing transactions envisioned under the Displacement Program, the following two benefits occur:
1. The DCCs avoid the transaction costs associated with exporting power from the CAISO; and
2. Both DCCs and NDCCs receive a benefit of the pricing difference between the IBAA export prices that DCCs pay the CAISO for their exports, and the IBAA import prices that the NDCCs get paid by the CAISO for their BR, FPP, and Project Use (PU) imports into the CAISO, during periods when the IBAA export price exceeds the IBAA import price.
4.1.2 The transactions associated with the Displacement Program will generally be structured so that DCCs make NDCCs whole for benefits lost as a result of reduced or eliminated imports of BR, FPP and PU due to Displacement Program transactions. These benefits include payment by the DCCs to NDCCs for the ancillary services currently available from imports of BR, FPP, and PU firm power schedules. Integrated Forward Market (IFM) Load Uplift Obligation Inter-SC trades from NDCCs to DCCs provide the benefit that NDCCs would have realized with the import of BR, FPP, and PU firm power schedules. The payment of the energy cost component of the Displacement Program transactions will be accomplished by an Inter SC Trade at the NP15 EZ Gen Trading Hub.
Each Party will bear the costs of Inter-SC Trade transaction costs associated with Displacement Program transactions.
4.1.3 The benefits from this transaction are avoided DCC transaction costs plus the spread between the locational marginal prices (LMP) received by NDCCs for imports of BR, FPP, or PU into the CAISO and the LMPs paid by DCCs for the export of power from the CAISO. The shared savings will be structured into a payment based on the sharing of the transaction costs that the DCCs avoid by taking displacement energy, plus the sharing of the spread between the LMP for IBAA exports and the LMP for IBAA imports. The benefit of the transactions associated with the Displacement Program will be split equally between the NDCCs and the DCCs.
4.2 Avoided Transaction Cost Determination:
The following table shows the CAISO scheduling charges and their associated charge codes that will be used in the avoided transaction cost determination.
They represent the CAISO charges associated with exports avoided by the DCCs when Displacement Program transactions occur:
Table B-1
Components of the Avoided Transaction Costs
*Fixed charges may be changed from time-to-time by the CAISO, as implemented by CAISO tariff changes and notices to market participants.
**These charges will be multiplied by (-1) before using them for the calculations of Variable Avoided Costs.
To determine the shared savings for the Avoided Transaction Costs, the total Avoided Fixed Charges in Table B-1 will be added to the sum of Avoided Variable Charges in Table B-1 (as they appear in actual settlement statements), and then divided by two. The result will be the shared Avoided Transaction Costs which will result in a payment from DCCs to NDCCs for each MWh of displacement energy
At any time that Western is notified that the charges associated with the Fixed Charges identified in Table B-1 above are revised, Western will revise this Exhibit B to reflect the updated charges and will issue a revised Exhibit B. The effective date of the revised Exhibit B will be the effective date of the updated charge.
4.3 Shared LMP Spread Savings Rate:
The variable shared savings is based upon a sharing of the difference between the LMPs received by NDCCs for imports of BR, FPP, or PU into the CAISO (based upon the NDCC-specific LMP), and the LMPs paid by DCCs for export of power from the CAISO (based upon the DCC-specific LMP). For the examples in this Section 4 regarding the sharing of the difference in import and export LMPs, it is assumed that all DCCs and NDCCs either have the same export LMP, or the same import LMP. Under IBAA as implemented by the CAISO, any DCC's or NDCC's import LMP or export LMP will vary, based upon the location used for scheduling the import into the CAISO or export out of the CAISO. Details on how to treat varying LMPs are set forth in the Settlements Section of this Exhibit B.
For this Section 4.3, variables shown in the formulae are as follows.
DCCExp = the LMP paid by DCCs for export of power from the CAISO NDCCImp = the LMP received by NDCCs for imports of BR, FPP, or PU into the CAISO
FTHub = the Financial Trading Hub LMP (at NP15 EZ Gen Trading Hub) Total LMP Benefit:
= DCCExp-NDCCImp
4.3.1 DCCs will execute Inter-SC Trades with the NDCCs at one (or more) of the financial trading hubs in order to settle the transaction between them (see Exhibit C). The Parties agree to use the NP15 EZ Gen Trading Hub for the financial trading hub transactions. The use of Inter-SC Trade transactions at the NP15 EZ Gen Trading Hub results in LMP Benefit to the Parties as follows:
NDCC Spread:
= FTHub - NDCCImp
DCC Spread:
= DCCExp -FTHub
4.3.2 With the allocation of the LMP benefit spread using the formula above, the formula for the shared LMP benefit can be expressed as follows: Determine the shared Spread Benefits by dividing the sum of the NDCC Spread and the DCC Spread from 4.3.1 in half.
Shared Benefit:
= 0.5 x (NDCC Spread + DCC Spread)
4.3.3 From the perspective of the NDCCs, they will have to share their net benefit by returning to the DCCs one half of the difference between their NDCC Spread Benefit and the Shared Benefit in accordance with the 50/50 rule. This can be expressed in the following formula:
Payment from NDCCs to DCCs:
= NDCC Spread -[0.5 x (NDCC Spread+DCC Spread)]
Inserting the LMP formulae from Step 4.3.1 above, the Payment formula can be expressed as follows:
Payment from NDCCs to DCCs:
= (FTHub - IBAA Imp) -[0.5 x ([FTHub - IBAA Imp]+ [IBAAExp - FTHub])] The formula can be reduced for terms that can be combined or that cancel each other. Here are the reducing steps and the resulting simplified Payment formula:
Payment rate from NDCCs to DCCs ($/MWh of displaced energy):
= (FTHub - IBAA Imp) -[0.5 x (IBAAExp - IBAA Imp)]
= (FTHub - IBAA lmp )+[0.5x( IBAA Imp- IBAAExp)]
= FTHub - [0.5 x ( IBAA lmp + IBAAExp)]
Positive amounts represent sums owed by the NDCCs to the DCCs.
4.4 Value of Ancillary Services:
Rather than execute Inter-SC Trades to transfer the DCC's avoided ancillary services obligations to the NDCCs (which lose the ancillary services credit by not scheduling BR or FPP as an import into the CAISO), the Parties have elected to settle the ancillary services financially, with a payment from the DCCs to the NDCCs.
For this Section 4.4, variables shown in the formulae are as follows:
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The payment rate for the value of the spinning and non-spinning reserves associated with the displacement transactions will be determined by the following formula:
Ancillary Services Rate for Payment from DCCs to NDCCs
= 0.035 x Spin + 0.035 x NonSpin
4.5 Total Shared Savings:
The Total Shared Savings is determined by subtracting the Fixed Shared Savings Payment from the Variable Shared Savings Payment:
Total Shared Savings:
= Shared Spread Savings - Shared Avoided Transaction Costs - Ancillary Services
Positive Total Shared Savings indicates payments are made from NDCCs to DCCs. Negative Total Shared Savings indicates payments are made from DCCs to NDCCs.
5. Settlements:
The following process will be used for settling payments between the DCCs and NDCCs and for collecting Displacement Program administrative costs from the Parties.
5.1 For settlements between the Parties, the Parties will use the Displacement Program Administrator as the settlements agent.
5.2 The Billing Period will be by calendar month. All Shared Savings Payments during any Billing Period due from or to any Party will be summed for the Billing Period such that the Party makes or receives one payment for the settlement of the Shared Savings Payments.
5.2.1 Hourly settlement information for the LMP spreads will be finalized after the CAISO has published the final LMPs. Preliminary settlement information can be provided prior to finalization. The Shared Savings Settlements can be provided on the following schedule:
Initial settlement information: After close of IFM and upon publishing of LMPs by CAISO
Final settlement information: T + 8 days, based upon publishing of final LMPs by CAISO
5.3 Displacement Program Administrative costs will be added (or netted against) into any Party's Shared Savings Payments due or payable. Recovery of the Displacement Program Administrative costs shall be in accordance with the terms and conditions outlined in the Displacement Program Administrator Contract. In general, the administrative costs will be allocated 50/50 to DCCs and NDCCs.
5.4 The settlement process shall be structured such that any Party will either make a single payment to the Displacement Program Administrator or receive a single payment from the Displacement Program Administrator for its sharing of the benefits and costs of participation in the Displacement Program for any given billing period.
5.5 Settlement of the Avoided Transaction Savings: Eighteen (18) charge code types determine the Avoided Transaction Costs when DCCs schedule in lieu of exporting from the CAISO. Table B-1 shows the charge codes that will be used for settling the shared Avoided Transaction Costs between the Displacement Program Participants. The rates associated with the first three (3) charge codes on the list are determined by tariff, and remain fixed until the CAISO files a tariff change and issues a notice to market participants. The other charge types are all determined in the settlements process, and are not known in advance. For purposes of settlements for the Displacement Program, the values for these charges will be obtained from actual settlement statements of one (1) or more NDCCs.
For this Section 5.5, variables shown in the formulae are as follows.
CAISO Chargei = Charge type i from Table B-1 where i is the index number of the charge type listing in the table, from 1 to 18.
j = the total number of charge types used in the shared avoided transaction cost calculation, currently 18.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
The shared avoided transaction payment made by DCC d is calculated as follows:
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the Avoided Transaction Costs payment.
The shared avoided transaction payment received by NDCC n is calculated as follows:
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared Avoided Transaction Costs payment.
5.6 Settlement of the Shared LMP Spread Benefit. Because the LMPs that apply for the variable savings calculation described in Section 4 above will vary based upon where a Party schedules an import in to or an export out of the CAISO, any single Party that is in either the NDCC or DCC class will settle the LMP portion of the variable shared savings by comparing the LMP of their avoided scheduling point, with the weighted average LMP calculated for avoided transactions incurred by the other class of Party taking part in Displacement in any given hour.
For this Section 5.6, variables shown in the formulae are as follows.
DCCExpd = the avoided export LMP for DCC d in the given hour, where d indexes from 1 up to the total number of participating DCCs.
DCCExpave = the weighted average avoided export LMP for all DCCs.
NDCCImpn = the avoided import LMP for NDCC n in the given hour where n indexes from 1 up to the total number of participating NDCCs.
NDCCImpave = the weighted average avoided import LMP for all NDCCs.
N = total number of NDCC Displacement Program participants.
D = total number of DCC Displacement Program participants.
FTHub = the Financial Trading Hub LMP.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
5.6.1 Determine the weighted average LMPs for NDCCs and DCCs based upon the actual Displacement Program transactions for the hour.
5.6.2 Determine the shared savings amount owing from or to be paid to the Displacement Program Administrator.
The LMP portion of variable shared savings payment owed to, or to be received from the Displacement Program Administrator by NDCC n is:
Variable shared saving payment made by NDCC n
= Qnx [FTHub - 0.5 x (NDCC lmpn+ DCCExp ave)]
Positive amounts resulting from the formula above represent sums owed by the NDCCs to the Displacement Program Administrator for the variable shared savings component.
THE LMP portion of the Variable shared saving payment made by DCC d = Qdx [0.5 x ( NDCC Impave + DCCExpd)- FTHub]
Positive amounts resulting from the formula above represent sums owed by the DCCs to the Displacement Program Administrator for the variable shared savings component.
Rounding of settlement amounts will occur on total net billing period amounts.
Hourly settlement amounts will not be rounded.
5.7 Settlement for the ancillary service obligation. To settle for the ancillary service credit that the NDCCs lose by avoiding import of BR, FPP, and PU into the CAISO, each DCC will make payment for the ancillary service charges to the Displacement Program Administrator, who will then make payments to each NDCC for the BR, FPP, of PU import that was displaced.
For this section 5.7, variables shown in the formulae are as follows:
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The ancillary services replacement payment made by DCC d is calculated as follows:
Ancillary Services Payment made by DCCs
= Qdx[0.035 x Spin + 0.035 x NonSpin]
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the ancillary services replacement.
The shared ancillary service replacement payment received by NDCC n is calculated as follows:
= - Qnx[0.035 x Spin + 0.035 x NonSpin]
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared avoided transaction costs payment.
5.8 The Parties agree that once Parties' obligations under the Displacement Program for any given month are adjusted following the CAISO Initial Reissue Invoices, there will be no retroactive changes to the charges incurred under this Contract for said month.
5.9 Settlements Timing:
Table B-2 below shows the Displacement Program settlements timeline.
6. Review of Charge Codes: Table B-3 below shows the charge codes that were reviewed for determining their applicability in the shared savings calculations.
Exhibit B
(Settlements and Shared Savings Methodology)
1. This Exhibit B, Revision 8, to be effective under and as a part of Contract 09-SNR-01256 (Contract) shall become effective on September 1, 2009; and shall remain in effect until either superseded by another Exhibit B or termination of the Contract.
2. Western will revise this Exhibit B, as needed, in accordance with the procedures set forth in Exhibit D to this Contract. The Parties agree that they have granted Western the right to make unilateral changes to Exhibit B in accordance with the terms and conditions agreed to by the Parties and set forth in Section 11 of the Contract. Each time a revision is made to this Exhibit B Western will issue an original of the revised exhibit to all Parties to this Contract.
3. This Exhibit B describes the steps for Settlements under the Displacement Program and the methodology to compute the net savings (or costs) of the Displacement Program and determines payments between the NDCCs and the DCCs to share the savings (or costs). Any expression in this Exhibit B preceded by the equals sign ("=") is a mathematical formula, and the following symbols in any such expression mean:
"x" is the mathematical operator for multiplication.
"/" is the mathematical operator for division
"+" is the mathematical operator for addition
"-" is the mathematical operator for subtraction, and when preceding a number or a variable may also mean the negative value of that number or variable.
4. Shared Savings Calculations:
The net savings (or net cost) realized through the Contract will be shared using the following methodology:
4.1 Assumptions:
4.1.1 The fundamental premise of the Displacement Program is that by executing transactions envisioned under the Displacement Program, the following two benefits occur:
1. The DCCs avoid the transaction costs associated with exporting power from the CAISO; and
2. Both DCCs and NDCCs receive a benefit of the pricing difference between the IBAA export prices that DCCs pay the CAISO for their exports, and the IBAA import prices that the NDCCs get paid by the CAISO for their BR, FPP, and Project Use (PU) imports into the CAISO, during periods when the IBAA export price exceeds the IBAA import price.
4.1.2 The transactions associated with the Displacement Program will generally be structured so that DCCs make NDCCs whole for benefits lost as a result of reduced or eliminated imports of BR, FPP and PU due to Displacement Program transactions. These benefits include payment by the DCCs to NDCCs for the ancillary services currently available from imports of BR, FPP, and PU firm power schedules. Integrated Forward Market (IFM) Load Uplift Obligation Inter-SC trades from NDCCs to DCCs provide the benefit that NDCCs would have realized with the import of BR, FPP, and PU firm power schedules. The payment of the energy cost component of the Displacement Program transactions will be accomplished by an Inter SC Trade at the NP15 EZ Gen Trading Hub.
Each Party will bear the costs of Inter-SC Trade transaction costs associated with Displacement Program transactions.
4.1.3 The benefits from this transaction are avoided DCC transaction costs plus the spread between the locational marginal prices (LMP) received by NDCCs for imports of BR, FPP, or PU into the CAISO and the LMPs paid by DCCs for the export of power from the CAISO. The shared savings will be structured into a payment based on the sharing of the transaction costs that the DCCs avoid by taking displacement energy, plus the sharing of the spread between the LMP for IBAA exports and the LMP for IBAA imports. The benefit of the transactions associated with the Displacement Program will be split equally between the NDCCs and the DCCs.
4.2 Avoided Transaction Cost Determination:
The following table shows the CAISO scheduling charges and their associated charge codes that will be used in the avoided transaction cost determination.
They represent the CAISO charges associated with exports avoided by the DCCs when Displacement Program transactions occur:
Table B-1
Components of the Avoided Transaction Costs
*Fixed charges may be changed from time-to-time by the CAISO, as implemented by CAISO tariff changes and notices to market participants.
**These charges will be multiplied by (-1) before using them for the calculations of Variable Avoided Costs.
To determine the shared savings for the Avoided Transaction Costs, the total Avoided Fixed Charges in Table B-1 will be added to the sum of Avoided Variable Charges in Table B-1 (as they appear in actual settlement statements), and then divided by two. The result will be the shared Avoided Transaction Costs which will result in a payment from DCCs to NDCCs for each MWh of displacement energy
At any time that Western is notified that the charges associated with the Fixed Charges identified in Table B-1 above are revised, Western will revise this Exhibit B to reflect the updated charges and will issue a revised Exhibit B. The effective date of the revised Exhibit B will be the effective date of the updated charge.
4.3 Shared LMP Spread Savings Rate:
The variable shared savings is based upon a sharing of the difference between the LMPs received by NDCCs for imports of BR, FPP, or PU into the CAISO (based upon the NDCC-specific LMP), and the LMPs paid by DCCs for export of power from the CAISO (based upon the DCC-specific LMP). For the examples in this Section 4 regarding the sharing of the difference in import and export LMPs, it is assumed that all DCCs and NDCCs either have the same export LMP, or the same import LMP. Under IBAA as implemented by the CAISO, any DCC's or NDCCs import LMP or export LMP will vary, based upon the location used for scheduling the import into the CAISO or export out of the CAISO. Details on how to treat varying LMPs are set forth in the Settlements Section of this Exhibit B.
For this Section 4.3, variables shown in the formulae are as follows.
DCCExp = the LMP paid by DCCs for export of power from the CAISO NDCCImp = the LMP received by NDCCs for imports of BR, FPP, or PU into the CAISO
FTHub = the Financial Trading Hub LMP (at NP15 EZ Gen Trading Hub) Total LMP Benefit:
= DCCExp - NDCCImp
4.3.1 DCCs will execute Inter-SC Trades with the NDCCs at one (or more) of the financial trading hubs in order to settle the transaction between them (see Exhibit C). The Parties agree to use the NP15 EZ Gen Trading Hub for the financial trading hub transactions. The use of Inter-SC Trade transactions at the NP15 EZ Gen Trading Hub results in LMP Benefit to the Parties as follows:
NDCC Spread:
= FTHub -NDCCImp
DCC Spread:
= DCCExp-FTHub
4.3.2 With the allocation of the LMP benefit spread using the formula above, the formula for the shared LMP benefit can be expressed as follows: Determine the shared Spread Benefits by dividing the sum of the NDCC Spread and the DCC Spread from 4.3.1 in half.
Shared Benefit:
= 0.5 x (NDCC Spread+DCC Spread)
4.3.3 From the perspective of the NDCCs, they will have to share their net benefit by returning to the DCCs one half of the difference between their NDCC Spread Benefit and the Shared Benefit in accordance with the 50/50 rule. This can be expressed in the following formula:
Payment from NDCCs to DCCs:
= NDCC Spread [0.5 x (NDCC Spread+DCC Spread)]
Inserting the LMP formulae from Step 4.3.1 above, the Payment formula can be expressed as follows:
Payment from NDCCs to DCCs:
= (FTHub - IBAA Imp) -[0.5 x ([FTHub - IBAA Imp]+ [IBAAExp - FTHub])] The formula can be reduced for terms that can be combined or that cancel each other. Here are the reducing steps and the resulting simplified Payment formula:
Payment rate from NDCCs to DCCs ($/MWh of displaced energy):
= (FTHub - IBAA Imp) -[0.5 x (IBAAExp - IBAA Imp)]
= (FTHub - IBAA lmp )+[0.5x( IBAA Imp- IBAAExp)]
= FTHub -[0.5 x ( IBAA lmp + IBAAExp)]
Positive amounts represent sums owed by the NDCCs to the DCCs.
4.4 Value of Ancillary Services:
Rather than execute Inter-SC Trades to transfer the DCC's avoided ancillary services obligations to the NDCCs (which lose the ancillary services credit by not scheduling BR or FPP as an import into the CAISO), the Parties have elected to settle the ancillary services financially, with a payment from the DCCs to the NDCCs.
For this Section 4.4, variables shown in the formulae are as follows:
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The payment rate for the value of the spinning and non-spinning reserves associated with the displacement transactions will be determined by the following formula:
Ancillary Services Rate for Payment from DCCs to NDCCs
= 0.035 x Spin + 0.035 x NonSpin
4.5 Total Shared Savings:
The Total Shared Savings is determined by subtracting the Fixed Shared Savings Payment from the Variable Shared Savings Payment:
Total Shared Savings:
= Shared Spread Savings - Shared Avoided Transaction Costs - Ancillary Services
Positive Total Shared Savings indicates payments are made from NDCCs to DCCs. Negative Total Shared Savings indicates payments are made from DCCs to NDCCs.
5. Settlements:
The following process will be used for settling payments between the DCCs and NDCCs and for collecting Displacement Program administrative costs from the Parties.
5.1 For settlements between the Parties, the Parties will use the Displacement Program Administrator as the settlements agent.
5.2 The Billing Period will be by calendar month. All Shared Savings Payments during any Billing Period due from or to any Party will be summed for the Billing Period such that the Party makes or receives one payment for the settlement of the Shared Savings Payments.
5.2.1 Hourly settlement information for the LMP spreads will be finalized after the CAISO has published the final LMPs. Preliminary settlement information can be provided prior to finalization. The Shared Savings Settlements can be provided on the following schedule:
Initial settlement information: After close of IFM and upon publishing of LMPs by CAISO
Final settlement information: T + 8 days, based upon publishing of final LMPs by CAISO
5.3 Displacement Program Administrative costs will be added (or netted against) into any Party's Shared Savings Payments due or payable. Recovery of the Displacement Program Administrative costs shall be in accordance with the terms and conditions outlined in the Displacement Program Administrator Contract. In general, the administrative costs will be allocated 50/50 to DCCs and NDCCs.
5.4 The settlement process shall be structured such that any Party will either make a single payment to the Displacement Program Administrator or receive a single payment from the Displacement Program Administrator for its sharing of the benefits and costs of participation in the Displacement Program for any given billing period.
5.5 Settlement of the Avoided Transaction Savings: Eighteen (18) charge code types determine the Avoided Transaction Costs when DCCs schedule in lieu of exporting from the CAISO. Table B-1 shows the charge codes that will be used for settling the shared Avoided Transaction Costs between the Displacement Program Participants. The rates associated with the first three (3) charge codes on the list are determined by tariff, and remain fixed until the CAISO files a tariff change and issues a notice to market participants. The other charge types are all determined in the settlements process, and are not known in advance. For purposes of settlements for the Displacement Program, the values for these charges will be obtained from actual settlement statements of one (1) or more NDCCs.
For this Section 5.5, variables shown in the formulae are as follows.
CAISO Chargei = Charge type i from Table B-1 where i is the index number of the charge type listing in the table, from 1 to 18.
j = the total number of charge types used in the shared avoided transaction cost calculation, currently 18.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
The shared avoided transaction payment made by DCC d is calculated as follows:
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the Avoided Transaction Costs payment.
The shared avoided transaction payment received by NDCC n is calculated as follows:
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared Avoided Transaction Costs payment.
5.6 Settlement of the Shared LMP Spread Benefit. Because the LMPs that apply for the variable savings calculation described in Section 4 above will vary based upon where a Party schedules an import in to or an export out of the CAISO, any single Party that is in either the NDCC or DCC class will settle the LMP portion of the variable shared savings by comparing the LMP of their avoided scheduling point, with the weighted average LMP calculated for avoided transactions incurred by the other class of Party taking part in Displacement in any given hour.
For this Section 5.6, variables shown in the formulae are as follows.
DCCExpd = the avoided export LMP for DCC d in the given hour, where d indexes from 1 up to the total number of participating DCCs.
DCCExpave = the weighted average avoided export LMP for all DCCs.
NDCCImpn = the avoided import LMP for NDCC n in the given hour where n indexes from 1 up to the total number of participating NDCCs.
NDCCImpave = the weighted average avoided import LMP for all NDCCs.
N = total number of NDCC Displacement Program participants.
D = total number of DCC Displacement Program participants.
FTHub = the Financial Trading Hub LMP.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
5.6.1 Determine the weighted average LMPs for NDCCs and DCCs based upon the actual Displacement Program transactions for the hour.
5.6.2 Determine the shared savings amount owing from or to be paid to the Displacement Program Administrator.
The LMP portion of variable shared savings payment owed to, or to be received from the Displacement Program Administrator by NDCC n is:
Variable shared saving payment made by NDCC n
= Qn x [FTHub - 0.5 x ( NDCC Impn + DCCExpave)]
Positive amounts resulting from the formula above represent sums owed by the NDCCs to the Displacement Program Administrator for the variable shared savings component.
THE LMP portion of the Variable shared saving payment made by DCC d = Qdx [0.5x( NDCC Impave + DCCExpd)- FTHub]
Positive amounts resulting from the formula above represent sums owed by the DCCs to the Displacement Program Administrator for the variable shared savings component.
Rounding of settlement amounts will occur on total net billing period amounts.
Hourly settlement amounts will not be rounded.
5.7 Settlement for the ancillary service obligation. To settle for the ancillary service credit that the NDCCs lose by avoiding import of BR, FPP, and PU into the CAISO, each DCC will make payment for the ancillary service charges to the Displacement Program Administrator, who will then make payments to each NDCC for the BR, FPP, of PU import that was displaced.
For this section 5.7, variables shown in the formulae are as follows:
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The ancillary services replacement payment made by DCC d is calculated as follows:
Ancillary Services Payment made by DCCs
= Qdx[0.035 x Spin + 0.035 x NonSpin]
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the ancillary services replacement.
The shared ancillary service replacement payment received by NDCC n is calculated as follows:
= - Qnx[0.035 x Spin + 0.035 x NonSpin]
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared avoided transaction costs payment.
5.8 The Parties agree that once Parties' obligations under the Displacement Program for any given month are adjusted following the CAISO Initial Reissue Invoices, there will be no retroactive changes to the charges incurred under this Contract for said month.

Each Party will bear the costs of Inter-SC Trade transaction costs associated with Displacement Program transactions.
4.1.3 The benefits from this transaction are avoided DCC transaction costs plus the spread between the locational marginal prices (LMP) received by NDCCs for imports of BR, FPP, or PU into the CAISO and the LMPs paid by DCCs for the export of power from the CAISO. The shared savings will be structured into a payment based on the sharing of the transaction costs that the DCCs avoid by taking displacement energy, plus the sharing of the spread between the LMP for IBAA exports and the LMP for IBAA imports. The benefit of the transactions associated with the Displacement Program will be split equally between the NDCCs and the DCCs.
4.2 Avoided Transaction Cost Determination:
The following table shows the CAISO scheduling charges and their associated charge codes that will be used in the avoided transaction cost determination.
They represent the CAISO charges associated with exports avoided by the DCCs when Displacement Program transactions occur:
Table B-1
Components of the Avoided Transaction Costs
Fixed charges may be changed from time-to-time by the CAISO, as implemented by CAISO tariff changes and notices to market participants.
**These charges will be multiplied by (-1) before using them for the calculations of Variable Avoided Costs.
To determine the shared savings for the Avoided Transaction Costs, the total Avoided Fixed Charges in Table B-1 will be added to the sum of Avoided Variable Charges in Table B-1 (as they appear in actual settlement statements), and then divided by two. The result will be the shared Avoided Transaction Costs which will result in a payment from DCCs to NDCCs for each MWh of displacement energy
At any time that Western is notified that the charges associated with the Fixed Charges identified in Table B-1 above are revised, Western will revise this Exhibit B to reflect the updated charges and will issue a revised Exhibit B. The effective date of the revised Exhibit B will be the effective date of the updated charge.
4.3 Shared LMP Spread Savings Rate:
The variable shared savings is based upon a sharing of the difference between the LMPs received by NDCCs for imports of BR, FPP, or PU into the CAISO (based upon the NDCC-specific LMP), and the LMPs paid by DCCs for export of power from the CAISO (based upon the DCC-specific LMP). For the examples in this Section 4 regarding the sharing of the difference in import and export LMPs, it is assumed that all DCCs and NDCCs either have the same export LMP, or the same import LMP. Under IBAA as implemented by the CAISO, any DCC's or NDCC's import LMP or export LMP will vary, based upon the location used for scheduling the import into the CAISO or export out of the CAISO. Details on how to treat varying LMPs are set forth in the Settlements Section of this Exhibit B.
For this Section 4.3, variables shown in the formulae are as follows.
DCCExp = the LMP paid by DCCs for export of power from the CAISO NDCCImp = the LMP received by NDCCs for imports of BR, FPP, or PU into the CAISO
FTHub = the Financial Trading Hub LMP (at NP15 EZ Gen Trading Hub) Total LMP Benefit:
= DCCExp-NDCCImp
4.3.1 DCCs will execute Inter-SC Trades with the NDCCs at one (or more) of the financial trading hubs in order to settle the transaction between them (see Exhibit C). The Parties agree to use the NP15 EZ Gen Trading Hub for the financial trading hub transactions. The use of Inter-SC Trade transactions at the NP15 EZ Gen Trading Hub results in LMP Benefit to the Parties as follows:
NDCC Spread:
= FTHub -NDCCImp
DCC Spread:
= DCCExp -FTHub
4.3.2 With the allocation of the LMP benefit spread using the formula above, the formula for the shared LMP benefit can be expressed as follows: Determine the shared Spread Benefits by dividing the sum of the NDCC Spread and the DCC Spread from 4.3.1 in half.
Shared Benefit:
= 0.5 x (NDCC Spread + DCC Spread)
4.3.3 From the perspective of the NDCCs, they will have to share their net benefit by returning to the DCCs one half of the difference between their NDCC Spread Benefit and the Shared Benefit in accordance with the 50/50 rule. This can be expressed in the following formula:
Payment from NDCCs to DCCs:
= NDCC Spread -[0.5 x (NDCC Spread+DCC Spread)]
Inserting the LMP formulae from Step 4.3.1 above, the Payment formula can be expressed as follows:
Payment from NDCCs to DCCs:
= (FTHub - IBAA Imp) -[0.5 x ([FTHub - IBAA Imp]+ [IBAAExp - FTHub])] The formula can be reduced for terms that can be combined or that cancel each other. Here are the reducing steps and the resulting simplified Payment formula:
Payment rate from NDCCs to DCCs ($/MWh of displaced energy):
= (FTHub - IBAA Imp) -[0.5 x (IBAAExp - IBAA Imp)]
= (FTHub - IBAA Imp )+[0.5x( IBAA Imp- IBAAExp)]
= FTHub -[0.5 x ( IBAA lmp + IBAAExp)]
Positive amounts represent sums owed by the NDCCs to the DCCs.
4.4 Value of Ancillary Services:
Rather than execute Inter-SC Trades to transfer the DCC's avoided ancillary services obligations to the NDCCs (which lose the ancillary services credit by not scheduling BR or FPP as an import into the CAISO), the Parties have elected to settle the ancillary services financially, with a payment from the DCCs to the NDCCs.

Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The payment rate for the value of the spinning and non-spinning reserves associated with the displacement transactions will be determined by the following formula:
Ancillary Services Rate for Payment from DCCs to NDCCs
= 0.035 x Spin + 0.035 x NonSpin
4.5 Total Shared Savings:
The Total Shared Savings is determined by subtracting the Fixed Shared Savings Payment from the Variable Shared Savings Payment:
Total Shared Savings:
= Shared Spread Savings - Shared Avoided Transaction Costs - Ancillary Services
Positive Total Shared Savings indicates payments are made from NDCCs to DCCs. Negative Total Shared Savings indicates payments are made from DCCs to NDCCs.
5. Settlements:
The following process will be used for settling payments between the DCCs and NDCCs and for collecting Displacement Program administrative costs from the Parties.
5.1 For settlements between the Parties, the Parties will use the Displacement Program Administrator as the settlements agent.
5.2 The Billing Period will be by calendar month. All Shared Savings Payments during any Billing Period due from or to any Party will be summed for the Billing Period such that the Party makes or receives one payment for the settlement of the Shared Savings Payments.

Final settlement information: T + 8 days, based upon publishing of final LMPs by CAISO
5.3 Displacement Program Administrative costs will be added (or netted against) into any Party's Shared Savings Payments due or payable. Recovery of the Displacement Program Administrative costs shall be in accordance with the terms and conditions outlined in the Displacement Program Administrator Contract. In general, the administrative costs will be allocated 50/50 to DCCs and NDCCs.
5.4 The settlement process shall be structured such that any Party will either make a single payment to the Displacement Program Administrator or receive a single payment from the Displacement Program Administrator for its sharing of the benefits and costs of participation in the Displacement Program for any given billing period.

The shared avoided transaction payment received by NDCC n is calculated as follows:
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared Avoided Transaction Costs payment.
5.6 Settlement of the Shared LMP Spread Benefit. Because the LMPs that apply for the variable savings calculation described in Section 4 above will vary based upon where a Party schedules an import in to or an export out of the CAISO, any single Party that is in either the NDCC or DCC class will settle the LMP portion of the variable shared savings by comparing the LMP of their avoided scheduling point, with the weighted average LMP calculated for avoided transactions incurred by the other class of Party taking part in Displacement in any given hour.
For this Section 5.6, variables shown in the formulae are as follows.

5.6.1 Determine the weighted average LMPs for NDCCs and DCCs based upon the actual Displacement Program transactions for the hour.
5.6.2 Determine the shared savings amount owing from or to be paid to the Displacement Program Administrator.
The LMP portion of variable shared savings payment owed to, or to be received from the Displacement Program Administrator by NDCC n is:
Variable shared saving payment made by NDCC n
= Qnx[FTHub - 0.5 x ( NDCC Impn + DCCExpave)]
Positive amounts resulting from the formula above represent sums owed by the NDCCs to the Displacement Program Administrator for the variable shared savings component.
THE LMP portion of the Variable shared saving payment made by DCC d = Qdx [0.5x( NDCC Impave + DCCExp d) - FTHub]
Positive amounts resulting from the formula above represent sums owed by the DCCs to the Displacement Program Administrator for the variable shared savings component.
Rounding of settlement amounts will occur on total net billing period amounts.
Hourly settlement amounts will not be rounded.
5.7 Settlement for the ancillary service obligation. To settle for the ancillary service credit that the NDCCs lose by avoiding import of BR, FPP, and PU into the CAISO, each DCC will make payment for the ancillary service charges to the Displacement Program Administrator, who will then make payments to each NDCC for the BR, FPP, of PU import that was displaced.
For this section 5.7, variables shown in the formulae are as follows:
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.

Ancillary Services Payment made by DCCs
= Qdx[0.035 x Spin + 0.035 x NonSpin]
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the ancillary services replacement.
The shared ancillary service replacement payment received by NDCC n is calculated as follows:
= - Qnx[0.035 x Spin + 0.035 x NonSpin]
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared avoided transaction costs payment.
5.8 The Parties agree that once Parties' obligations under the Displacement Program for any given month are adjusted following the CAISO Initial Reissue Invoices, there will be no retroactive changes to the charges incurred under this Contract for said month.
5.9 Settlements Timing:
Table B-2 below shows the Displacement Program settlements timeline.
6. Review of Charge Codes: Table B-3 below shows the charge codes that were reviewed for determining their applicability in the shared savings calculations.
Exhibit B
(Settlements and Shared Savings Methodology)
1. This Exhibit B, Revision 10, to be effective under and as a part of Contract 09-SNR-01256 (Contract) shall become effective on January 1, 2010; and shall remain in effect until either superseded by another Exhibit B or termination of the Contract.
2. Western will revise this Exhibit B, as needed, in accordance with the procedures set forth in Exhibit D to this Contract. The Parties agree that they have granted Western the right to make unilateral changes to Exhibit B in accordance with the terms and conditions agreed to by the Parties and set forth in Section 11 of the Contract. As of this Exhibit B, Revision 10, Tables B-1 through B-3 are included as Attachment 1 and remain a part of this Exhibit B. Each time a revision is made to this Exhibit B, Western will issue an original of the revised exhibit/attachment (as applicable) to all Parties to this Contract.
3. This Exhibit B describes the steps for Settlements under the Displacement Program and the methodology to compute the net savings (or costs) of the Displacement Program and determines payments between the NDCCs and the DCCs to share the savings (or costs). Any expression in this Exhibit B preceded by the equals sign ("=") is a mathematical formula, and the following symbols in any such expression mean:
"x" is the mathematical operator for multiplication.
"/" is the mathematical operator for division
"+" is the mathematical operator for addition
"-" is the mathematical operator for subtraction, and when preceding a number or a variable may also mean the negative value of that number or variable.
4. Shared Savings Calculations:
The net savings (or net cost) realized through the Contract will be shared using the following methodology:
4.1 Assumptions:
4.1.1 The fundamental premise of the Displacement Program is that by executing transactions envisioned under the Displacement Program, the following two benefits occur:
1. The DCCs avoid the transaction costs associated with exporting power from the CAISO; and
2. Both DCCs and NDCCs receive a benefit of the pricing difference between the IBAA export prices that DCCs pay the CAISO for their exports, and the IBAA import prices that the NDCCs get paid by the CAISO for their BR, FPP, and Project Use (PU) imports into the CAISO, during periods when the IBAA export price exceeds the IBAA import price.
4.1.2 The transactions associated with the Displacement Program will generally be structured so that DCCs make NDCCs whole for benefits lost as a result of reduced or eliminated imports of BR, FPP and PU due to Displacement Program transactions. These benefits include payment by the DCCs to NDCCs for the ancillary services currently available from imports of BR, FPP, and PU firm power schedules. Integrated Forward Market (IFM) Load Uplift Obligation Inter-SC trades from NDCCs to DCCs provide the benefit that NDCCs would have realized with the import of BR, FPP, and PU firm power schedules. The payment of the energy cost component of the Displacement Program transactions will be accomplished by an Inter SC Trade at the NP15 EZ Gen Trading Hub.
Each Party will bear the costs of Inter-SC Trade transaction costs associated with Displacement Program transactions.
4.1.3 The benefits from this transaction are avoided DCC transaction costs plus the spread between the locational marginal prices (LMP) received by NDCCs for imports of BR, FPP, or PU into the CAISO and the LMPs paid by DCCs for the export of power from the CAISO. The shared savings will be structured into a payment based on the sharing of the transaction costs that the DCCs avoid by taking displacement energy, plus the sharing of the spread between the LMP for IBAA exports and the LMP for IBAA imports. The benefit of the transactions associated with the Displacement Program will be split equally between the NDCCs and the DCCs.
4.2 Avoided Transaction Cost Determination:
The following table shows the CAISO scheduling charges and their associated charge codes that will be used in the avoided transaction cost determination.
They represent the CAISO charges associated with exports avoided by the DCCs when Displacement Program transactions occur:
To determine the shared savings for the Avoided Transaction Costs, the total Avoided Fixed Charges in Table B-1 will be added to the sum of Avoided Variable Charges in Table B-1 (as they appear in actual settlement statements), and then divided by two. The result will be the shared Avoided Transaction Costs which will result in a payment from DCCs to NDCCs for each MWh of displacement energy
At any time that Western is notified that the charges associated with the Fixed Charges identified in Table B-1 are revised, Western will revise Attachment 1 to this Exhibit B to reflect the updated charges and will issue a revised Attachment 1 to Exhibit B. The effective date of the revised Attachment 1 to Exhibit B will be the effective date of the updated charge.
4.3 Shared LMP Spread Savings Rate:
The variable shared savings is based upon a sharing of the difference between the LMPs received by NDCCs for imports of BR, FPP, or PU into the CAISO (based upon the NDCC-specific LMP), and the LMPs paid by DCCs for export of power from the CAISO (based upon the DCC-specific LMP). For the examples in this Section 4 regarding the sharing of the difference in import and export LMPs, it is assumed that all DCCs and NDCCs either have the same export LMP, or the same import LMP. Under IBAA as implemented by the CAISO, any DCC's or NDCCs import LMP or export LMP will vary, based upon the location used for scheduling the import into the CAISO or export out of the CAISO. Details on how to treat varying LMPs are set forth in the Settlements Section of this Exhibit B.
For this Section 4.3, variables shown in the formulae are as follows.
DCCExp = the LMP paid by DCCs for export of power from the CAISO NDCCImp = the LMP received by NDCCs for imports of BR, FPP, or PU into the CAISO
FTHub = the Financial Trading Hub LMP (at NP15 EZ Gen Trading Hub) Total LMP Benefit:
= DCCExp-NDCCImp
4.3.1 DCCs will execute Inter-SC Trades with the NDCCs at one (or more) of the financial trading hubs in order to settle the transaction between them (see Exhibit C). The Parties agree to use the NP15 EZ Gen Trading Hub for the financial trading hub transactions. The use of Inter-SC Trade transactions at the NP15 EZ Gen Trading Hub results in LMP Benefit to the Parties as follows:
NDCC Spread:
= FTHub -NDCCImp
DCC Spread:
= DCCExp-FTHub
4.3.2 With the allocation of the LMP benefit spread using the formula above, the formula for the shared LMP benefit can be expressed as follows: Determine the shared Spread Benefits by dividing the sum of the NDCC Spread and the DCC Spread from 4.3.1 in half.
Shared Benefit:
= 0.5 x (NDCC Spread+DCC Spread)
4.3.3 From the perspective of the NDCCs, they will have to share their net benefit by returning to the DCCs one half of the difference between their NDCC Spread Benefit and the Shared Benefit in accordance with the 50/50 rule. This can be expressed in the following formula:
Payment from NDCCs to DCCs:
= NDCC Spread -[0.5 x (NDCC Spread+DCC Spread)]
Inserting the LMP formulae from Step 4.3.1 above, the Payment formula can be expressed as follows:
Payment from NDCCs to DCCs:
= (FTHub - IBAA Imp) -[0.5 x ([FTHub - IBAA Imp]+ [IBAAExp - FTHub])] The formula can be reduced for terms that can be combined or that cancel each other. Here are the reducing steps and the resulting simplified Payment formula:
Payment rate from NDCCs to DCCs ($/MWh of displaced energy):
= (FTHub - IBAA Imp) -[0.5 x (IBAAExp - IBAA Imp)]
= (FTHub - IBAA Imp) + [0.5 x ( IBAA Imp- IBAAExp)]
= FTHub -[0.5 x ( IBAA lmp + IBAAExp)]
Positive amounts represent sums owed by the NDCCs to the DCCs.
4.4 Value of Ancillary Services:
Rather than execute Inter-SC Trades to transfer the DCC's avoided ancillary services obligations to the NDCCs (which lose the ancillary services credit by not scheduling BR or FPP as an import into the CAISO), the Parties have elected to settle the ancillary services financially, with a payment from the DCCs to the NDCCs.
For this Section 4.4, variables shown in the formulae are as follows:
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The payment rate for the value of the spinning and non-spinning reserves associated with the displacement transactions will be determined by the following formula:
Ancillary Services Rate for Payment from DCCs to NDCCs
= 0.035 x Spin + 0.035 x NonSpin
4.5 Total Shared Savings:
The Total Shared Savings is determined by subtracting the Fixed Shared Savings Payment from the Variable Shared Savings Payment:
Total Shared Savings:
= Shared Spread Savings - Shared Avoided Transaction Costs - Ancillary Services
Positive Total Shared Savings indicates payments are made from NDCCs to DCCs. Negative Total Shared Savings indicates payments are made from DCCs to NDCCs.
5. Settlements:
The following process will be used for settling payments between the DCCs and NDCCs and for collecting Displacement Program administrative costs from the Parties.
5.1 For settlements between the Parties, the Parties will use the Displacement Program Administrator as the settlements agent.
5.2 The Billing Period will be by calendar month. All Shared Savings Payments during any Billing Period due from or to any Party will be summed for the Billing Period such that the Party makes or receives one payment for the settlement of the Shared Savings Payments.
5.2.1 Hourly settlement information for the LMP spreads will be finalized after the CAISO has published the final LMPs. Preliminary settlement information can be provided prior to finalization. The Shared Savings Settlements can be provided on the following schedule:
Initial settlement information: After close of IFM and upon publishing of LMPs by CAISO
Final settlement information: T + 8 days, based upon publishing of final LMPs by CAISO
5.3 Displacement Program Administrative costs will be added (or netted against) into any Party's Shared Savings Payments due or payable. Recovery of the Displacement Program Administrative costs shall be in accordance with the terms and conditions outlined in the Displacement Program Administrator Contract. In general, the administrative costs will be allocated 50/50 to DCCs and NDCCs.
5.4 The settlement process shall be structured such that any Party will either make a single payment to the Displacement Program Administrator or receive a single payment from the Displacement Program Administrator for its sharing of the benefits and costs of participation in the Displacement Program for any given billing period.
5.5 Settlement of the Avoided Transaction Savings: Eighteen (18) charge code types determine the Avoided Transaction Costs when DCCs schedule in lieu of exporting from the CAISO. Table B-1 shows the charge codes that will be used for settling the shared Avoided Transaction Costs between the Displacement Program Participants. The rates associated with the first three (3) charge codes on the list are determined by tariff, and remain fixed until the CAISO files a tariff change and issues a notice to market participants. The other charge types are all determined in the settlements process, and are not known in advance. For purposes of settlements for the Displacement Program, the values for these charges will be obtained from actual settlement statements of one (1) or more NDCCs.
For this Section 5.5, variables shown in the formulae are as follows.
CAISO Chargei = Charge type i from Table B-1 where i is the index number of the charge type listing in the table, from 1 to 18.
j = the total number of charge types used in the shared avoided transaction cost calculation, currently 18.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
The shared avoided transaction payment made by DCC d is calculated as follows:
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the Avoided Transaction Costs payment.
The shared avoided transaction payment received by NDCC n is calculated as follows:
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared Avoided Transaction Costs payment.
5.6 Settlement of the Shared LMP Spread Benefit. Because the LMPs that apply for the variable savings calculation described in Section 4 above will vary based upon where a Party schedules an import in to or an export out of the CAISO, any single Party that is in either the NDCC or DCC class will settle the LMP portion of the variable shared savings by comparing the LMP of their avoided scheduling point, with the weighted average LMP calculated for avoided transactions incurred by the other class of Party taking part in Displacement in any given hour.
For this Section 5.6, variables shown in the formulae are as follows.
DCCExpd = the avoided export LMP for DCC d in the given hour, where d indexes from 1 up to the total number of participating DCCs.
DCCExpave = the weighted average avoided export LMP for all DCCs.
NDCCImpn = the avoided import LMP for NDCC n in the given hour where n indexes from 1 up to the total number of participating NDCCs.
NDCCImpave = the weighted average avoided import LMP for all NDCCs.
N = total number of NDCC Displacement Program participants.
D = total number of DCC Displacement Program participants.
FTHub = the Financial Trading Hub LMP.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
5.6.1 Determine the weighted average LMPs for NDCCs and DCCs based upon the actual Displacement Program transactions for the hour.
5.6.2 Determine the shared savings amount owing from or to be paid to the Displacement Program Administrator.
The LMP portion of variable shared savings payment owed to, or to be received from the Displacement Program Administrator by NDCC n is:
Variable shared saving payment made by NDCC n
= Q n x [FTHub - 0.5 x ( NDCC Impn + DCCExpave)]
Positive amounts resulting from the formula above represent sums owed by the NDCCs to the Displacement Program Administrator for the variable shared savings component.
THE LMP portion of the Variable shared saving payment made by DCC d = Qd x [0.5 x ( NDCC Impave + DCCExpd) - FTHub]
Positive amounts resulting from the formula above represent sums owed by the DCCs to the Displacement Program Administrator for the variable shared savings component.
Rounding of settlement amounts will occur on total net billing period amounts.
Hourly settlement amounts will not be rounded.
5.7 Settlement for the ancillary service obligation. To settle for the ancillary service credit that the NDCCs lose by avoiding import of BR, FPP, and PU into the CAISO, each DCC will make payment for the ancillary service charges to the Displacement Program Administrator, who will then make payments to each NDCC for the BR, FPP, of PU import that was displaced.
For this section 5.7, variables shown in the formulae are as follows:
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The ancillary services replacement payment made by DCC d is calculated as follows:
Ancillary Services Payment made by DCCs
= Qdx[0.035 x Spin + 0.035 x NonSpin]
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the ancillary services replacement.
The shared ancillary service replacement payment received by NDCC n is calculated as follows:
= - Qnx[0.035 x Spin + 0.035 x NonSpin]
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared avoided transaction costs payment.
5.8 The Parties agree that once Parties' obligations under the Displacement Program for any given month are adjusted following the CAISO Initial Reissue Invoices, there will be no retroactive changes to the charges incurred under this Contract for said month.

Dear Mr. Roukema:
The Western Area Power Administration (Western) and the City of Santa Clara, Silicon Valley Power (SVP) are parties to Contract 09-SNR-01256 (Contract). This Contract provides for SVP’s participation in Western’s Base Resource Displacement Program.
Western is revising Exhibit B to the Contract to reflect the change in the Federal Energy Regulatory Commission’s Order 789 on ancillary service obligations in the California Independent System Operator market, and how such change impacts the settlements associated with the Displacement Program. The percentage used to calculate the true-up for spinning and non- spinning reserves decreased from 3.5
were revised to reflect this change. The revised Exhibit B is effective as of October 1, 2014.
Enclosed for your records is an original of Exhibit B, Revision 11 to the Contract. If you have any questions, please contact Mr. Hiroshi Kashiwagi of my staff at (916) 353-4477 or [email protected].
Enclosure
Exhibit B, Revision 11 to
Contract 09-SNR-01256
Exhibit B
(Settlements and Shared Savings Methodology)
1. This Exhibit B, Revision 11, to be effective under and as a part of Contract 09-SNR-01256 (Contract) shall become effective on October 1, 2014; and shall remain in effect until either superseded by another Exhibit B or termination of the Contract.
2. Western will revise this Exhibit B, as needed, in accordance with the procedures set forth in Exhibit D to this Contract. The Parties agree that they have granted Western the right to make unilateral changes to Exhibit B in accordance with the terms and conditions agreed to by the Parties and set forth in Section 11 of the Contract. As of this Exhibit B, Revision 11, Tables B-1 through B-3 are included as Attachment 1 and remain a part of this Exhibit B. Each time a revision is made to this Exhibit B, Western will issue an original of the revised exhibit/attachment (as applicable) to all Parties to this Contract.
3. This Exhibit B describes the steps for Settlements under the Displacement Program and the methodology to compute the net savings (or costs) of the Displacement Program and determines payments between the NDCCs and the DCCs to share the savings (or costs). Any expression in this Exhibit B preceded by the equals sign (“=”) is a mathematical formula, and the following symbols in any such expression mean:
“x” is the mathematical operator for multiplication.
"/” is the mathematical operator for division
“+" is the mathematical operator for addition
"-" is the mathematical operator for subtraction, and when preceding a number or a variable may also mean the negative value of that number or variable.
4. Shared Savings Calculations:
The net savings (or net cost) realized through the Contract will be shared using the following methodology:
4.1 Assumptions:
4.1.1 The fundamental premise of the Displacement Program is that by executing transactions envisioned under the Displacement Program, the following two benefits occur:
1. The DCCs avoid the transaction costs associated with exporting power from the CAISO; and
2. Both DCCs and NDCCs receive a benefit of the pricing difference between the I BAA export prices that DCCs pay the CAISO for their exports, and the IBAA import prices that the NDCCs get paid by the CAISO for their BR, FPP, and Project Use
Exhibit B, Revision 11 to
Contract 09-SNR-01256
(PU) imports into the CAISO, during periods when the IBAA export price exceeds the IBAA import price.
4.1.2 The transactions associated with the Displacement Program will generally be structured so that DCCs make NDCCs whole for benefits lost as a result of reduced or eliminated imports of BR, FPP and PU due to Displacement Program transactions. These benefits include payment by the DCCs to NDCCs for the ancillary services currently available from imports of BR, FPP, and PU firm power schedules. Integrated Forward Market (IFM) Load Uplift Obligation Inter-SC trades from NDCCs to DCCs provide the benefit that NDCCs would have realized with the import of BR, FPP, and PU firm power schedules. The payment of the energy cost component of the Displacement Program transactions will be accomplished by an Inter SC Trade at the NP15 EZ Gen Trading Hub.
Each Party will bear the costs of Inter-SC Trade transaction costs associated with Displacement Program transactions.
4.1.3 The benefits from this transaction are avoided DCC transaction costs plus the spread between the locational marginal prices (LMP) received by NDCCs for imports of BR, FPP, or PU into the CAISO and the LMPs paid by DCCs for the export of power from the CAISO. The shared savings will be structured into a payment based on the sharing of the transaction costs that the DCCs avoid by taking displacement energy, plus the sharing of the spread between the LMP for IBAA exports and the LMP for IBAA imports. The benefit of the transactions associated with the Displacement Program will be split equally between the NDCCs and the DCCs.
4.2 Avoided Transaction Cost Determination:
The following table shows the CAISO scheduling charges and their associated charge codes that will be used in the avoided transaction cost determination.
They represent the CAISO charges associated with exports avoided by the DCCs when Displacement Program transactions occur:
To determine the shared savings for the Avoided Transaction Costs, the total Avoided Fixed Charges in Table B-1 will be added to the sum of Avoided Variable Charges in Table B-1 (as they appear in actual settlement statements), and then divided by two. The result will be the shared Avoided Transaction Costs which will result in a payment from DCCs to NDCCs for each MWh of displacement energy
Shared Avoided Transaction Costs
= Avoided Fixed Transaction Costs + Avoided Variable Transaction Costs 2
Exhibit B, Revision 11 to
Contract 09-SNR-01256
At any time that Western is notified that the charges associated with the Fixed Charges identified in Table B-1 are revised, Western will revise Attachment 1 to this Exhibit B to reflect the updated charges and will issue a revised Attachment 1 to Exhibit B. The effective date of the revised Attachment 1 to Exhibit B will be the effective date of the updated charge.
4.3 Shared LMP Spread Savings Rate:
The variable shared savings is based upon a sharing of the difference between the LMPs received by NDCCs for imports of BR, FPP, or PU into the CAISO (based upon the NDCC-specific LMP), and the LMPs paid by DCCs for export of power from the CAISO (based upon the DCC-specific LMP). For the examples in this Section 4 regarding the sharing of the difference in import and export LMPs, it is assumed that all DCCs and NDCCs either have the same export LMP, or the same import LMP. Under IBAA as implemented by the CAISO, any DCC’s or NDCC’s import LMP or export LMP will vary, based upon the location used for scheduling the import into the CAISO or export out of the CAISO. Details on how to treat varying LMPs are set forth in the Settlements Section of this Exhibit B.
For this Section 4.3, variables shown in the formulae are as follows.
DCCExp = the LMP paid by DCCs for export of power from the CAISO NDCCImp = the LMP received by NDCCs for imports of BR, FPP, or PU into the CAISO
FTHub = the Financial Trading Hub LMP (at NP15 EZ Gen Trading Hub) Total LMP Benefit:
= DCCExp - NDCCImp
4.3.1 DCCs will execute Inter-SC Trades with the NDCCs at one (or more) of the financial trading hubs in order to settle the transaction between them (see Exhibit C). The Parties agree to use the NP15 EZ Gen Trading Hub for the financial trading hub transactions. The use of Inter-SC Trade transactions at the NP15 EZ Gen Trading Hub results in LMP Benefit to the Parties as follows:
NDCC Spread:
= FTHub - NDCCImp
DCC Spread:
= DCCExp - FTHub
4.3.2 With the allocation of the LMP benefit spread using the formula above, the formula for the shared LMP benefit can be expressed as follows: Determine the shared Spread Benefits by dividing the sum of the NDCC Spread and the DCC Spread from 4.3.1 in half.
Exhibit B, Revision 11 to
Contract 09-SNR-01256
Shared Benefit:
= 0.5 x (NDCC Spread+DCC Spread)
4.3.3 From the perspective of the NDCCs, they will have to share their net benefit by returning to the DCCs one half of the difference between their NDCC Spread Benefit and the Shared Benefit in accordance with the 50/50 rule. This can be expressed in the following formula:
Payment from NDCCs to DCCs:
= NDCC Spread - [0.5 x (NDCC Spread+DCC Spread)]
Inserting the LMP formulae from Step 4.3.1 above, the Payment formula can be expressed as follows:
Payment from NDCCs to DCCs:
= (FTHub - IBAAlmp)-[0.5 x ([FTHub - IBAA lmp]+[lBAAExp-FTHub])] The formula can be reduced for terms that can be combined or that cancel each other. Here are the reducing steps and the resulting simplified Payment formula:
Payment rate from NDCCs to DCCs ($/MWh of displaced energy):
= (FTHub - IBAA Im p) - [0.5 x (IBAAExp - IBAA Im p)]
= (FTHub - IBAA Im p) + [0.5 x (IBAA Imp- IBAAExp)]
= FTHub - [0.5 x (IBAA lmp + IBAAExp)]
Positive amounts represent sums owed by the NDCCs to the DCCs.
4.4 Value of Ancillary Services:
Rather than execute Inter-SC Trades to transfer the DCC’s avoided ancillary services obligations to the NDCCs (which lose the ancillary services credit by not scheduling BR or FPP as an import into the CAISO), the Parties have elected to settle the ancillary services financially, with a payment from the DCCs to the NDCCs.
For this Section 4.4, variables shown in the formulae are as follows:
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Exhibit B, Revision 11 to
Contract 09-SNR-01256
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The payment rate for the value of the spinning and non-spinning reserves associated with the displacement transactions will be determined by the following formula:
Ancillary Services Rate for Payment from DCCs to NDCCs
= 0.015 x Spin + 0.015 x NonSpin
4.5 Total Shared Savings:
The Total Shared Savings is determined by subtracting the Fixed Shared Savings Payment from the Variable Shared Savings Payment:
Total Shared Savings:
= Shared Spread Savings - Shared Avoided Transaction Costs - Ancillary Services
Positive Total Shared Savings indicates payments are made from NDCCs to DCCs. Negative Total Shared Savings indicates payments are made from DCCs to NDCCs.
5. Settlements:
The following process will be used for settling payments between the DCCs and NDCCs and for collecting Displacement Program administrative costs from the Parties.
5.1 For settlements between the Parties, the Parties will use the Displacement Program Administrator as the settlements agent.
5.2 The Billing Period will be by calendar month. All Shared Savings Payments during any Billing Period due from or to any Party will be summed for the Billing Period such that the Party makes or receives one payment for the settlement of the Shared Savings Payments.
5.2.1 Hourly settlement information for the LMP spreads will be finalized after the CAISO has published the final LMPs. Preliminary settlement information can be provided prior to finalization. The Shared Savings Settlements can be provided on the following schedule:
Initial settlement information: After close of IFM and upon publishing of LMPs by CAISO
Final settlement information: T + 8 days, based upon publishing of final LMPs by CAISO
Exhibit B, Revision 11 to
Contract 09-SNR-01256
5.3 Displacement Program Administrative costs will be added (or netted against) into any Party’s Shared Savings Payments due or payable. Recovery of the Displacement Program Administrative costs shall be in accordance with the terms and conditions outlined in the Displacement Program Administrator Contract. In general, the administrative costs will be allocated 50/50 to DCCs and NDCCs.
5.4 The settlement process shall be structured such that any Party will either make a single payment to the Displacement Program Administrator or receive a single payment from the Displacement Program Administrator for its sharing of the benefits and costs of participation in the Displacement Program for any given billing period.
5.5 Settlement of the Avoided Transaction Savings: Eighteen (18) charge code types determine the Avoided Transaction Costs when DCCs schedule in lieu of exporting from the CAISO. Table B-1 shows the charge codes that will be used for settling the shared Avoided Transaction Costs between the Displacement Program Participants. The rates associated with the first three (3) charge codes on the list are determined by tariff, and remain fixed until the CAISO files a tariff change and issues a notice to market participants. The other charge types are all determined in the settlements process, and are not known in advance. For purposes of settlements for the Displacement Program, the values for these charges will be obtained from actual settlement statements of one (1) or more NDCCs.
For this Section 5.5, variables shown in the formulae are as follows.
CAISO Chargej = Charge type i from Table B-1 where i is the index number of the charge type listing in the table, from 1 to 18.
j = the total number of charge types used in the shared avoided transaction cost calculation, currently 18.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
The shared avoided transaction payment made by DCC d is calculated as follows:
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the Avoided Transaction Costs payment.
Exhibit B, Revision 11 to
Contract 09-SNR-01256
The shared avoided transaction payment received by NDCC n is calculated as follows:
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared Avoided Transaction Costs payment.
5.6 Settlement of the Shared LMP Spread Benefit. Because the LMPs that apply for the variable savings calculation described in Section 4 above will vary based upon where a Party schedules an import in to or an export out of the CAISO, any single Party that is in either the NDCC or DCC class will settle the LMP portion of the variable shared savings by comparing the LMP of their avoided scheduling point, with the weighted average LMP calculated for avoided transactions incurred by the other class of Party taking part in Displacement in any given hour.
For this Section 5.6, variables shown in the formulae are as follows.
the avoided export LMP for DCC d in the given hour, where d indexes from 1 up to the total number of participating DCCs. the weighted average avoided export LMP for all DCCs.
the avoided import LMP for NDCC n in the given hour where n indexes from 1 up to the total number of participating NDCCs. = the weighted average avoided import LMP for all NDCCs.
N = total number of NDCC Displacement Program participants.
D = total number of DCC Displacement Program participants.
FTHub = the Financial Trading Hub LMP.
Qd = the amount of Displacement scheduled by DCC d in the given hour.
Qn = the amount of Displacement scheduled by NDCC n in the given hour.
5.6.1 Determine the weighted average LMPs for NDCCs and DCCs based upon the actual Displacement Program transactions for the hour.
Exhibit B, Revision 11 to
Contract 09-SNR-01256
5.6.2 Determine the shared savings amount owing from or to be paid to the Displacement Program Administrator.
The LMP portion of variable shared savings payment owed to, or to be received from the Displacement Program Administrator by NDCC n is:
Positive amounts resulting from the formula above represent sums owed by the NDCCs to the Displacement Program Administrator for the variable shared savings component.
Positive amounts resulting from the formula above represent sums owed by the DCCs to the Displacement Program Administrator for the variable shared savings component.
Rounding of settlement amounts will occur on total net billing period amounts.
Hourly settlement amounts will not be rounded.
5.7 Settlement for the ancillary service obligation. To settle for the ancillary service credit that the NDCCs lose by avoiding import of BR, FPP, and PU into the CAISO, each DCC will make payment for the ancillary service charges to the Displacement Program Administrator, who will then make payments to each NDCC for the BR, FPP, of PU import that was displaced.
For this section 5.7, variables shown in the formulae are as follows:
the amount of Displacement scheduled by DCC d in the given hour. the amount of Displacement scheduled by NDCC n in the given hour.
the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Exhibit B, Revision 11 to
Contract 09-SNR-01256
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The ancillary services replacement payment made by DCC d is calculated as follows:
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the ancillary services replacement.
The shared ancillary service replacement payment received by NDCC n is calculated as follows:
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared avoided transaction costs payment.
5.8 The Parties agree that once Parties’ obligations under the Displacement Program for any given month are adjusted following the CAISO Initial Reissue Invoices, there will be no retroactive changes to the charges incurred under this Contract for said month.

Dear Mr. Roukema:
The Western Area Power Administration (Western) and the City of Santa Clara, Silicon Valley Power (SVP) are parties to Contract 09-SNR-01256 (Contract). This Contract provides for SVP’s participation in Western’s Base Resource Displacement Program (DP).
In anticipation of the start of the DP this year, Western revised Exhibit A, Attachment 1 to Exhibit B, and Exhibit D, to the Contract. Western revised Exhibit A to change the pricing point for some of the participants to reflect the California Independent System Operator’s (CAISO) Market Efficiency Enhancement Agreement pricing. Attachment 1 was revised to include the most current CAISO charges that make up the avoided fixed transaction costs related to the DP. The CAISO’s Charge Code 6496 (Peak Reliability Coordinator Charge) was also added to the table as an additional fixed transaction charge. Exhibit D was revised to update the DP working group representatives.
Enclosed for your records are Exhibit A, Revision 9,
Attachment 1, Revision 28 to Exhibit B, and
Exhibit D, Revision 8, to the Contract. If you have any questions, please contact Mr. Hiroshi Kashiwagi of my staff at (916) 353-4477 or [email protected].

(Settlements and Shared Savings Methodology)
1. This Exhibit B, Revision 12, to be effective under and as a part of Contract 09-SNR-01256 (Contract) shall become effective on November 1, 2018; and shall remain in effect until either superseded by another Exhibit B or termination of the Contract.
2. Western will revise this Exhibit B, as needed, in accordance with the procedures set forth in Exhibit D to this Contract. The Parties agree that they have granted Western the right to make unilateral changes to Exhibit B in accordance with the terms and conditions agreed to by the Parties and set forth in Section 11 of the Contract. As of this Exhibit B, Revision 12, Tables B-1 through B-3 are included as Attachment 1 and remain a part of this Exhibit B. Each time a revision is made to this Exhibit B, Western will issue an original of the revised exhibit/attachment (as applicable) to all Parties to this Contract.
3. This Exhibit B describes the steps for Settlements under the Displacement Program and the methodology to compute the net savings (or costs) of the Displacement Program and determines payments between the NDCCs and the DCCs to share the savings (or costs). Any expression in this Exhibit B preceded by the equals sign (“=”) is a mathematical formula, and the following symbols in any such expression mean:
4. Shared Savings Calculations:
The net savings (or net cost) realized through the Contract will be shared using the following methodology:
4.1 Assumptions:
4.1.1 The fundamental premise of the Displacement Program is that by executing transactions envisioned under the Displacement Program, the following two benefits occur:
1. The DCCs avoid the transaction costs associated with exporting power from the CAISO; and
2. Both DCCs and NDCCs receive a benefit of the pricing difference between the IBAA export prices that DCCs pay the CAISO for their exports, and the IBAA import prices that the NDCCs get paid by the CAISO for their BR, FPP, and Project Use (PU) imports into the CAISO, during periods when the 1BAA export price exceeds the IBAA import price.
4.1.2 The transactions associated with the Displacement Program will generally be structured so that DCCs make NDCCs whole for benefits lost as a result of reduced or eliminated imports of BR, FPP and PU due to Displacement Program transactions. These benefits include payment by the DCCs to NDCCs for the ancillary services currently available from imports of BR, FPP, and PU firm power schedules. Integrated Forward Market (IFM) Load Uplift Obligation Inter-SC trades from NDCCs to DCCs provide the benefit that NDCCs would have realized with the import of BR, FPP, and PU firm power schedules. The payment of the energy cost component of the Displacement Program transactions will be accomplished by an Inter SC Trade at the NP15 EZ Gen Trading Hub.
Each Party will bear the costs of Inter-SC Trade transaction costs associated with Displacement Program transactions.
4.1.3 The benefits from this transaction are avoided DCC transaction costs plus the spread between the locational marginal prices (LMP) received by NDCCs for imports of BR, FPP, or PU into the CAISO and the LMPs paid by DCCs for the export of power from the CAISO. The shared savings will be structured into a payment based on the sharing of the transaction costs that the DCCs avoid by taking displacement energy, plus the sharing of the spread between the LMP for IBAA exports and the LMP for IBAA imports. The benefit of the transactions associated with the Displacement Program will be split equally between the NDCCs and the DCCs.
4.2 Avoided Transaction Cost Determination:
The following table shows the CAISO scheduling charges and their associated charge codes that will be used in the avoided transaction cost determination.
They represent the CAISO charges associated with exports avoided by the DCCs when Displacement Program transactions occur:
To determine the shared savings for the Avoided Transaction Costs, the total Avoided Fixed Charges in Table B-1 will be added to the sum of Avoided Variable Charges in Table B-1 (as they appear in actual settlement statements), and then divided by two. The result will be the shared Avoided Transaction Costs which will result in a payment from DCCs to NDCCs for each MWh of displacement energy
At any time that Western is notified that the charges associated with the Fixed Charges identified in Table B-1 are revised, Western will revise Attachment 1 to this Exhibit B to reflect the updated charges and will issue a revised Attachment 1 to Exhibit B. The effective date of the revised Attachment 1 to Exhibit B will be the effective date of the updated charge.
4.3 Shared LMP Spread Sayings Rate:
The variable shared savings is based upon a sharing of the difference between the LMPs received by NDCCs for imports of BR, FPP, or PU into the CAISO (based upon the NDCC-specific LMP), and the LMPs paid by DCCs for export of power from the CAISO (based upon the DCC-specific LMP). For the examples in this Section 4 regarding the sharing of the difference in import and export LMPs, it is assumed that all DCCs and NDCCs either have the same export LMP, or the same import LMP. Linder IBAA as implemented by the CAISO, any DCC’s or NDCC’s import LMP or export LMP will vary, based upon the location used for scheduling the import into the CAISO or export out of the CAISO. Details on how to treat varying LMPs are set forth in the Settlements Section of this Exhibit B.
For this Section 4.3, variables shown in the formulae are as follows.
DCCExp = the LMP paid by DCCs for export of power from the CAISO NDCCImp = the LMP received by NDCCs for imports of BR, FPP, or PU into the CAISO
FTHub = the Financial Trading Hub LMP (at NP15 EZ Gen Trading Hub) Total LMP Benefit:
= DCCExp-NDCCImp
4.3.1 DCCs will execute Inter-SC Trades with the NDCCs at one (or more) of the financial trading hubs in order to settle the transaction between them (see Exhibit C). The Parties agree to use the NP15 EZ Gen Trading Hub for the financial trading hub transactions. The use of Inter-SC Trade transactions at the NP15 EZ Gen Trading Hub results in LMP Benefit to the Parties as follows:
NDCC Spread:
= FTHub -NDCCImp
DCC Spread:
= DCCExp -FTHub
4.3.2 With the allocation of the LMP benefit spread using the formula above, the formula for the shared LMP benefit can be expressed as follows: Determine the shared Spread Benefits by dividing the sum of the NDCC Spread and the DCC Spread from 4.3.1 in half.
Shared Benefit:
= 0.5 x (NDCC Spread+DCC Spread)
4.3.3 From the perspective of the NDCCs, they will have to share their net benefit by returning to the DCCs one half of the difference between their NDCC Spread Benefit and the Shared Benefit in accordance with the 50/50 rule. This can be expressed in the following formula:
Payment from NDCCs to DCCs:
= NDCC Spread -[0.5x(NDCC Spread+DCC Spread)]
Inserting the LMP formulae from Step 4.3.1 above, the Payment formula can be expressed as follows:
Positive amounts represent sums owed by the NDCCs to the DCCs.
4.4 Value of Ancillary Services:
Rather than execute Inter-SC Trades to transfer the DCC’s avoided ancillary services obligations to the NDCCs (which lose the ancillary services credit by not scheduling BR or FPP as an import into the CAISO), the Parties have elected to settle the ancillary services financially, with a payment from the DCCs to the NDCCs.
For this Section 4.4, variables shown in the formulae are as follows:
Spin = the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The payment rate for the value of the spinning and non-spinning reserves associated with the displacement transactions will be determined by the following formula:
Ancillary Services Rate for Payment from DCCs to NDCCs
= 0.015 x Spin + 0.015 x NonSpin
4.5 Total Shared Savings:
The Total Shared Savings is determined by subtracting the Fixed Shared Savings Payment from the Variable Shared Savings Payment:
Total Shared Savings:
= Shared Spread Savings - Shared Avoided Transaction Costs - Ancillary Services
Positive Total Shared Savings indicates payments are made from NDCCs to DCCs. Negative Total Shared Savings indicates payments are made from DCCs to NDCCs.
5. Settlements:
The following process will be used for settling payments between the DCCs and NDCCs and for collecting Displacement Program administrative costs from the Parties.
5.1 For settlements between the Parties, the Parties will use the Displacement Program Administrator as the settlements agent.
5.2 The Billing Period will be by calendar month. All Shared Savings Payments during any Billing Period due from or to any Party will be summed for the Billing Period such that the Party makes or receives one payment for the settlement of the Shared Savings Payments.
5.2.1 Hourly settlement information for the LMP spreads will be finalized after the CAISO has published the final LMPs. Preliminary settlement information can be provided prior to finalization. The Shared Savings Settlements can be provided on the following schedule:
Initial settlement information: After close of IFM and upon publishing of LMPs by CAISO
Final settlement information: T + 8 days, based upon publishing of final LMPs by CAISO
5.3 Displacement Program Administrative costs will be added (or netted against) into any Party’s Shared Savings Payments due or payable. Recovery of the Displacement Program Administrative costs shall be in accordance with the terms and conditions outlined in the Displacement Program Administrator Contract. In general, the administrative costs will be allocated 50/50 to DCCs and NDCCs.
5.4 The settlement process shall be structured such that any Party will either make a single payment to the Displacement Program Administrator or receive a single payment from the Displacement Program Administrator for its sharing of the benefits and costs of participation in the Displacement Program for any given billing period.
5.5 Settlement of the Avoided Transaction Savings: Eighteen (18) charge code types determine the Avoided Transaction Costs when DCCs schedule in lieu of exporting from the CAISO. Table B-1 shows the charge codes that will be used for settling the shared Avoided Transaction Costs between the Displacement Program Participants. The rates associated with the first three (3) charge codes on the list are determined by tariff, and remain fixed until the CAISO files a tariff change and issues a notice to market participants. The other charge types are all determined in the settlements process, and are not known in advance. For purposes of settlements for the Displacement Program, the values for these charges will be obtained from actual settlement statements of one (1) or more NDCCs.
For this Section 5.5, variables shown in the formulae are as follows.
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the Avoided Transaction Costs payment.
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared Avoided Transaction Costs payment.
5.6 Settlement of the Shared LMP Spread Benefit. Because the LMPs that apply for the variable savings calculation described in Section 4 above will vary based upon where a Party schedules an import in to or an export out of the CAISO, any single Party that is in either the NDCC or DCC class will settle the LMP portion of the variable shared savings by comparing the LMP of their avoided scheduling point, with the weighted average LMP calculated for avoided transactions incurred by the other class of Party taking part in Displacement in any given hour.
For this Section 5.6, variables shown in the formulae are as follows.
5.6.1 Determine the weighted average LMPs for NDCCs and DCCs based upon the actual Displacement Program transactions for the hour.
5.6.2 Determine the shared savings amount owing from or to be paid to the Displacement Program Administrator.
The LMP portion of variable shared savings payment owed to, or to be received from the Displacement Program Administrator by NDCC n is:
Positive amounts resulting from the formula above represent sums owed by the NDCCs to the Displacement Program Administrator for the variable shared savings component.
Positive amounts resulting from the formula above represent sums owed by the DCCs to the Displacement Program Administrator for the variable shared savings component.
Rounding of settlement amounts will occur on total net billing period amounts.
Hourly settlement amounts will not be rounded.
5.7 Settlement for the ancillary service obligation. To settle for the ancillary service credit that the NDCCs lose by avoiding import of BR, FPP, and PU into the CAISO, each DCC will make payment for the ancillary service charges to the Displacement Program Administrator, who will then make payments to each NDCC for the BR, FPP, of PU import that was displaced.
For this section 5.7, variables shown in the formulae are as follows:
the amount of Displacement scheduled by DCC d in the given hour. the amount of Displacement scheduled by NDCC n in the given hour.
the hourly system-wide user rate for spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Spin rate shall be the hourly spinning reserve price for NP15.
Non Spin = the hourly system-wide user rate for non-spinning reserve, except during periods when the CAISO declares zonal ancillary service prices, in which case the Non Spin rate shall be the hourly non spinning reserve price for NP15.
The ancillary services replacement payment made by DCC d is calculated as follows:
Positive amounts resulting from the formula above represent sums owed by a DCC to the Displacement Program Administrator for the ancillary services replacement.
The shared ancillary service replacement payment received by NDCC n is calculated as follows:
Negative amounts resulting from the formula above represent sums paid by the Displacement Program Administrator to NDCC n for the shared avoided transaction costs payment.
5.8 The Parties agree that once Parties’ obligations under the Displacement Program for any given month are adjusted following the CAISO Initial Reissue Invoices, there will be no retroactive changes to the charges incurred under this Contract for said month.

Exhibit C
(Displacement Program Scheduling Procedures)
1. This Exhibit C, to be effective under and as a part of Contract 09-SNR-01256 (Contract) shall become effective upon execution of the Contract; and shall remain in effect until either superseded by another Exhibit C or termination of the Contract.
2. Western will revise this Exhibit C, as needed, in accordance with the procedures set forth in Exhibit D to this Contract. The Parties agree that they have granted Western the right to make unilateral changes to Exhibit C in accordance with the terms and conditions agreed to by the Parties and set forth in Section 11 of the Contract. Each time a revision is made to this Exhibit C Western will issue an authenticated copy of the revised exhibit to all Parties to this Contract.
3. The CVP Corporation has contracted to be the Displacement Program Administrator (DPA). Whenever the term "DPA" is used in this Exhibit C, it shall mean CVP Corporation. The DPA shall be responsible for contracting for a Displacement Scheduling Aggregator, collecting Parties' fees for displacement participation, paying expenses for coordination, and disbursing payments to and collecting payments from Parties for the sharing of Displacement Program benefits. The cost for performing such services shall be set forth in the Displacement Program Administrator Contract executed between the DPA and the Parties. The Parties to this Contract shall be obligated to pay their share of the DPA's costs as set forth in the DPA Contract.
4. Robertson-Bryan, Inc. has contracted to be the Displacement Scheduling Aggregator (Aggregator). Whenever the term "Aggregator" is used in this Exhibit C, it shall mean Robertson-Bryan, Inc. The Aggregator's responsibilities and costs are set forth in the Displacement Scheduling Aggregator Contract (Displacement Program Aggregator Contract) executed between the DPA and the Aggregator. The Parties to this Contract shall be obligated to pay their share of the Aggregator's costs as set forth in the DPA Contract.
5. Western has contracted to be the Displacement Scheduling Coordinator (Displacement SC). Whenever the term "Displacement SC" is used in this Exhibit C, it shall mean Western. The Displacement SC's responsibilities and costs are set forth in the Displacement Program Scheduling Coordinator Exhibit (SC Contract) executed between the DPA and the Displacement SC. The Parties to this Contract shall be obligated to pay their share of the Displacement SC's costs as set forth in the DPA Contract. In addition the Parties to this Contract are obligated to perform any duties required of them in the SC Contract. The SC Contract is hereby incorporated as Attachment 1 to this Exhibit C. Identified below in this Section 5 are specific SC activities identified in the SC Contract. Wherever a DCC or NDCC is identified, they shall be responsible for the actions required, whether by their own performance or through an agent representing them.
5.1 The DPA is responsible to provide information for the Day-Ahead Inter-SC Trades of Energy and the Real Time Market Integrated Forward Market (IFM) Uplift Obligation Trades to the Displacement SC and the Scheduling Coordinators for each DCC and NDCC in accordance with the WECC Prescheduling calendar by at least two (2) hours prior to the close of the CAISO Day-Ahead Market as further defined in Section 6.6 of this Exhibit C. The DPA has contracted with the Aggregator to perform this service for the DPA. Western, DCCs and NDCCs shall make best efforts to use such data and/or information provided by the Aggregator to create the trades for the appropriate markets to the extent possible. For business weekdays, the Aggregator will provide such trade data two (2) hours prior to the close of the CAISO Scheduling Day-Ahead Market. For weekends and holidays, such trade data must be provided by 10:00 a.m. of the prescheduling day as prescribed in the WECC Prescheduling calendar.
5.2 Failure to get information in a timely manner from the Aggregator: If there is a failure of the Aggregator's software or systems that calculate and determine Displacement Program energy quantities and schedules such that the Displacement SC, DCCs, NDCCs, or their respective Scheduling Coordinators do not receive the required information from the Aggregator necessary to create the trades by 8:30 a.m. pacific prevailing time of the prescheduling day under the WECC Prescheduling calendar (one (1) hour thirty (30) minutes prior to the close of the CAISO Day-Ahead Market on days that the WECC Prescheduling calendar is the same as the CAISO Day-ahead Market), the Displacement SC, DCC and NDCC participants will not create the trades for the transactions, the amount of displacement energy and other associated trades calculated by the Aggregator will be considered void, and Western, the DCCs and the NDCCs will schedule their allocated share of Western BR as if the Displacement Program was not executed for the applicable trading period. If by 8:30 a.m. pacific prevailing time on prescheduling day under the WECC Prescheduling calendar as described above, the Aggregator is unable to provide said information, and the Aggregator is unable to confirm receipt of said information, the Aggregator will contact the Displacement SC and each of the DCC and NDCC participants, or their respective Scheduling Coordinators, and inform them that said information has not been provided and the Displacement Program will not be executed for the affected time period. Western, DCC and NDCC participants will make best efforts to contact the Aggregator and attempt to acquire such information, to the extent possible.
5.3 Failure by the Displacement SC, a DCC, or NDCC to successfully enter the required trades: Each DCC and NDCC is required to ensure that their Scheduling Coordinator submits all of the trades provided by the Aggregator, as identified in Section 5.1, to the correct MRTU Market within the applicable CAISO market time lines. The Displacement SC will make best efforts to submit the counter trades of the DCCs and NDCCs to the correct MRTU Market within the CAISO market time lines. In order to provide sufficient time to resolve any issues that may materialize in balancing trades, the Displacement SC and the DCCs and NDCCs, or their respective Scheduling Coordinators, will make best efforts to schedule all required trades at least one (1) hour prior to the close of the applicable CAISO Inter-SC Trade market time line.
5.3.1 If, after instructions have been successfully issued by the Aggregator, some of the Inter-SC Trades fail to be submitted or accepted by the CAISO for any reason, the Displacement SC, the appropriate DCCs and/or NDCCs, or their respective Scheduling Coordinators shall identify that an error has occurred, which could include unmatched trades or incomplete submission of bid components. Any affected DCC and/or NDCC, or their respective Scheduling Coordinators, and the Displacement SC along with the Aggregator, if required, will work in good faith to resolve any discrepancies before the relevant CAISO Inter-SC Trade market time line closes. However, if the Displacement SC, affected DCCs and/or NDCCs, or their respective Scheduling Coordinators, and the Aggregator fail to resolve the identified problem, and as a result certain required trades were unsuccessfully submitted into the CAISO market and therefore not accepted by the CAISO, the failed trades will be communicated to the Aggregator and settled financially as part of the monthly invoicing process. The financial settlement calculated by the Aggregator will be included within the affected party's monthly invoice, and will be equal to a settlement amount that would have cleared through the affected party's CAISO settlement statement as if the trades were submitted successfully and awarded in the applicable CAISO Inter-SC Trade market. No liability on the Displacement SC, any DCC or any NDCC, or the Aggregator will exist for failed trades other than the responsibility of the affected DCC and/or NDCC to settle financially directly with the DPA for the failed trades.
5.4 Western, as the Displacement SC, will report to the Aggregator any failure by Western, a DCC's or NDCC's Scheduling Coordinator to submit matched and valid trades by the close of the relevant markets. This information will be used by the Aggregator to calculate any required financial adjustments to the monthly invoices of the affected DCCs and/or NDCCs. The Aggregator will be responsible for sharing this information with the appropriate parties, such as the DPA, Displacement SC and/or DCC and NDCC participants.
6. Displacement Scheduling Procedures:
6.1 Energy exchanged from the DCCs resource positions in the CAISO will be transferred to NDCCs via CAISO financial Inter-SC Trade at the NP15 EZ Gen Trading Hub.
6.2 Each day the NDCCs shall have the option to offer their BR, FPP, or PU into the displacement pool for that day or continue to receive their BR, FPP, or PL) without change. The NDCCs shall determine what level of BR, FPP, or PU to offer into the displacement pool ("Offered Displacement Energy").
6.3 Regardless of whether an NDCC's BR, FPP, or PU is offered into the Displacement Program for the day, by executing this Contract, such NDCC understands that its BR, FPP, or PU data will be automatically sent to the Aggregator on a daily basis for informational purposes.
6.4 Displacement Program will be conducted through Inter-SC Trades submitted in conjunction with the appropriate CAISO Market.
6.5 The election by the NDCCs to participate in the displacement pool for a given day must be made in accordance with daily WECC prescheduling time frames as set forth in Section 6.6 of this Exhibit C.
6.6 Displacement Program Scheduling Time Line (synchronous with the WECC Prescheduling time frames):
6.7 Offered Displacement Energy will go into a pool for the DCCs.
Time of Day Activity
12:00 p.m. (T-2) Western posts BR Minimum/Maximum availability by customer to Western's portal
12:00 p.m. (T-2) Customers can start entering their Minimum/Maximum information into Western's portal. Even if Western provides notice that no BR is available for the active day, DCCs should continue to enter their load schedules in Western's portal because FPP or PU may be available for
displacement.
2:30 p.m. (T-2) Customers must have completed entry of their Minimum/Maximum information into Western's portal
3:00 p.m. (T-2) Western posts the final BR allocations, including Hourly Exchange information to the Western portal. Western
provides customers' BR allocation schedules to the
Aggregator upon a mutually agreed method.
3:00 p.m. (T-2) Customers can start the Displacement process. 7:45 a.m. (T-1) Displacement process closes. Aggregator starts computing displaced energy schedules for DCCs and NDCCs.
8:00 a.m. (T-1) Aggregator provides displacement energy schedule instructions to Western, DCCs and NDCCs.
10:00 a.m. (T-1) CAISO Day-Ahead Market Closes (CAISO Day-Ahead is a 7-day per week market)
12:00 p.m. (T-1) DA Inter-SC Trade deadline (CAISO Day-Ahead is a 7-day per week market)
1:00 p.m. (T-1) HA IFM uplift trade Opens (CAISO Day-Ahead is a 7-day per week market)
6.8 The Aggregator will collect and aggregate the NDCCs Offered Displacement Energy and allocate such Offered Displacement Energy to the DCCs based on their elected displacement amounts ("Elected Displacement Energy").
6.8.1 Offered Displacement Energy and Elected Displacement Energy will be scheduled in whole megawatt-hours, both at the participant level and at the aggregate level.
6.8.2 Aggregator will provide a breakdown of BR schedules net of displaced energy for Western's Full Load Service Customers in tens of kilowatt-hours.
6.8.3 The smaller energy quantity between the NDCC aggregate of Offered Displacement Energy and the DCC aggregate of Elected Displacement Energy will be identified as the displacement pool.
6.9 In the event that the DCC's Elected Displacement Energy is less than the NDCCs Offered Displacement Energy the Aggregator will determine the allocation of the displacement pool as follows:
6.9.1 The final amount of Offered Displacement Energy from the NDCCs will be scheduled in relative proportion to each NDCC's initially Offered Displacement Energy, while respecting each NDCC's scheduling of final non-displaced energy import in whole megawatt-hours.
6.9.2 When the aggregate of NDCC displacement is reduced to fit the size of the displacement pool, each NDCC's displacement allocation will be its percentage share of Offered Displacement Energy relative to the total of all of the Offered Displacement Energy, times the displacement pool energy; the actual displacement scheduled is the allocation rounded down to the nearest MWh.
6.9.2.1 If the displacement pool is large enough to schedule across all NDCCs, those whose schedule falls below 1 MWh will have their allocation rounded
up to 1 MWh. The NDCCs with an
allocation greater than 1 MWh will have their allocation rounded down to the nearest MWh. The rounding of displaced energy will create a pool of either surplus or deficit, when compared to the actual pool. This pool is called the Residual Pool Energy.
6.9.2.2 The Residual Pool Energy is the collection of
fractional changes required to have all the DCCs and NDCCs schedules in whole MWhs - the net result of the rounding down and rounding up.
6.9.2.3 The Residual Pool Energy will be successively spread in 1 MWh increments among the NDCCs in descending order of Offered Displacement Energy - after all NDCCs received 1 MW, the process would repeat the allocation in descending order. In the case that NDCCs have an equal hourly Offered Displacement Energy amount, the descending order shall derive from the daily Offered Displacement Energy amount.
6.9.2.4 If the displacement pool is insufficient to schedule at least 1 MWh across all DCCs, the Displacement Pool is treated the same as the Residual Pool Energy - spreading the Displacement Pool in 1 MWh increments in descending order of Offered Displacement Energy.
6.10 In the event that not all Elected Displacement Energy is fulfilled by the NDCCs, the DCCs will receive Offered Displacement Energy in proportion to their Elected Displacement Energy, relative to the total aggregated Elected Displacement Energy.
6.10.1 Each DCC's capacity to elect displacement energy is limited to its load, net of initial BR schedule and rounded down to the nearest MWh.
6.10.2 The available displacement pool energy is first divided into equal amounts among all DCCs and allocated per the following guidelines:
6.10.2.1 The available displacement pool energy is divided by the total number of DCCs, whether displacing or not at that hour.
The calculated DCC energy allocation is rounded down to the nearest MWh.
6.10.2.2 Energy is only allocated to the DCCs that are electing to receive displaced energy at that hour.
6.10.2.3 Energy allocation is capped by each DCCs capacity to receive displaced energy.
6.10.2.4 The first pool residual is the difference between the available displacement pool and the energy first allocated to the DCCs.
6.10.3 The first displacement pool residual is allocated between the DCCs in proportion to their relative capacities to elect displacement energy after the first allocation.
6.10.3.1 Energy allocation to each DCC is rounded down to the nearest MWh.
6.10.3.2 The second displacement pool residual is the
remaining displacement energy after allocation of the first displacement pool residual.
6.10.4 The second displacement pool residual results from rounding of displacement amounts, and iteratively allocated 1 MWh at a time among DCCs, starting from those with the largest remaining capacity to elect displacement energy. DCCs competing for last MWh allocation will be ranked by total Elected Displacement Energy in the day or week as necessary to select one DCC. If these selection criteria fail to single out one DCC, the Aggregator is authorized to allocate the last MWh randomly.
6.11 The Aggregator will then provide displacement scheduling instructions to the Displacement SC, the NDCCs and the DCCs for scheduling of displacement energy on the CAISO Day-Ahead Market.
6.12 The displacement process will close each day two (2) hours and fifteen (15) minutes before closure of the CAISO Inter-SC Trade Day-Ahead Market, or for weekends and holidays, in accordance with the WECC Prescheduling calendar and the Aggregator will have the displacement energy scheduling instructions available to the Displacement SC, the DCCs and the NDCCs no later than two (2) hours before closure of the CAISO Inter-SC Trade Day-Ahead Market, or in accordance with the WECC Prescheduling calendar.
6.13 When exercising displacement, the DCCs and NDCCs will use Inter-SC Trades to schedule IFM Uplift Obligation from the NDCCs to the DCCs. The Aggregator will provide instructions to the DCCs, NDCCs and the Displacement SC to facilitate these Inter-SC Trades.
6.14 When exercising displacement, the NDCCs and DCCs will use Inter-SC Trades to schedule energy between the DCCs and NDCCs in the CAISO Day- Ahead Market. The results of such trades will be included within CAISO settlements pursuant to the CAISO Tariff.
7. Specific Aggregator Duties:
7.1 Coordinating NDCCs and DCCs participation.
7.1.1 Aggregator will maintain accurate records of each DCC and NDCC, including, but not limited to, contact information, Trading Hub, Import or Export Pricing Node, BR Percentage Allocation and Direct or Non-Direct Connect Status. Such information may be updated occasionally by the DPA, Western, or the DCCs and NDCCs.
7.1.2 Aggregator will facilitate access to the Displacement Scheduling platform seven (7) days a week, twenty-four (24) hours a day.
7.2 Pooling the NDCCs Offered Displacement Energy.
7.3 Allocating Offered Displacement Energy to DCCs.
7.4 Providing scheduling instructions to the Displacement SC and the DCCs and NDCCs for the Offered Displacement Energy and the Elected Displacement Energy.
7.5 Tracking the relevant locational marginal prices (LMPs) published by the CAISO. The Aggregator will retrieve daily and store the LMPs for the Day-Ahead Market at each import, export, and trading hub node used in the Displacement Program, and the hourly reserve prices at the NP15 DLAP Preliminary LMPs will be refreshed and overwritten with final LMPs after ten (10) days.
7.6 Updating the displacement platform with the Inter-SC Trades that were executed and those that failed. The Aggregator will update the final settlements accordingly.
7.7 Maintaining records of CAISO Charge Code rates for the calculation of fixed shared savings payments. The rates may be changed as needed by the DPA, Western or the Aggregator.
7.8 Calculating and providing hourly settlement information for each DCC and NDCC. Settlement information will include hourly displaced energy, and fixed and variable savings. DCCs and NDCCs will have access to their own settlement information, whereas the DPA and Western will have access to all DCC's and NDCCs settlement information. Settlement reports will be in MS-Excel format.
Settlement report items will be labeled either preliminary or final, depending on the LMPs.
7.9 Generating invoices for payments to and from the DCCs and NDCCs to allocate the sharing of Displacement Program benefits.
7.9.1 Payment and credit statements (invoices) will be calculated from the hourly shared displacement savings.
7.9.2 DCCs and NDCCs will have access to their own invoicing information, whereas the DPA and Western will have access to all DCC's and NDCCs invoicing information.
7.9.3 The Aggregator will e-mail invoices to each DCC and NDCC.
Invoices will be in PDF format. Invoices will also be available for download from each DCC and NDCC.
7.9.4 A summary of DCCs and NDCCs invoiced payments and credits will be available to Western and the DPA in a MS-Excel file format.
7.10 Sending Western copies of all supporting documentation for transactions that occur each month by the 20th of the following month.
