2 Today’s Action
• Approve staff’s Net-Billing Tariff proposal for
CleanPowerSF.
• Proposal has been revised from one presented
to Commission on January 27, 2026.
• Approve accompanying revisions to
CleanPowerSF’s Net Energy Metering Tariff.
• If adopted, tariffs would be effective for the May
2027 billing period.
3 Net Energy Metering
• Net Energy Metering (NEM) is for
customers with on-site renewable energy
systems like solar.
• NEM customers earn credits for the
energy they send to the grid.
• Energy sent to the grid is credited at the
retail rate per kilowatt hour.

5 Staff’s January 2026 Solar Billing Plan Proposal
• Use California Public Utilities Commission’s approved energy export values for northern California with additional credits for local generation and low-income customers, in alignment with other community choice aggregation programs.
• This proposal faced criticism for:
• Linking our program to a CPUC-controlled process and valuation • Based on a regional rather than San Francisco-specific valuation of energy • Hourly rates would be difficult for customers to understand. 6 Revised Proposal
• Like Net Metering, proposal would use retail rates to credit solar energy exports, using:
• CleanPowerSF-specific average energy costs
• Easier-to-understand retail rate time-of-use periods. • Unlike Net Metering, proposal would exclude from credits the portion of CleanPowerSF's costs associated with running the program (non-energy fixed/administrative costs).
• Simplifies year-end true-up process by eliminating need for Net Surplus Compensation.
7 Proposed Solar Export Credit Calculation
• Export Credits would be calculated as the customer's retail rate minus CleanPowerSF's fixed costs, as determined through the City Charter-required cost of service process.

AGENDA ITEM
Public Utilities Commission
City and County of San Francisco
Calendar: Regular Calendar
Project Manager: Andrew Bevington
Approve CleanPowerSF ’s Net Billing Tariff Schedule and revisions to the CleanPowerSF Net Energy Metering Tariff Schedule
Summary of Proposed
Commission Action:
Public Hearing to consider possible action to approve :
1) the proposed “Electric Schedule NBT -CleanPowerSF,
Net Billing Tariff” (CleanPowerSF Net Billing Tariff) and 2) a revised “Electric Schedule NEM -CleanPowerSF, Net
Energy Metering” (NEM Tariff) both to be effective the first day of the May 2027 billing period. CleanPowerSF Net
Billing Tariff may also be referred to as the “Solar Billing Plan” in customer -facing communications. The Planning
Department has determined that the Project is exempt from the California Environmental Quality Act ( CEQA), and the Commission will rely on that determination to make its
decision on this action. This action constitutes the Approval Action for the Project for the purposes of the C EQA
pursuant to San Francisco Administrative Code S ection
31.04(h).
Background: Summary
Staff propose the adoption of the CleanPowerSF Net Billing Tariff. The new tariff would apply to CleanPowerSF
customers with onsite renewable generation systems, like rooftop solar, who receive electricity distribution from Pacific Gas & Electric Company (PG&E) and are served
under PG&E’s Net Billing Tariff . PG&E’s Net Billing Tariff applies to customers whose systems were approved for
interconnection after April 14, 2023. It also applies to customers on PG&E’s legacy Net Energy Metering tariff
who modify their systems or reach the end of their 20- year Net Energy Metering legacy period.
I. Proposed Net Billing Tariff
A. Rationale for Proposed Tariff Design
Under the NEM Tariff, energy sent to the grid by customers with onsite generation is compensated at CleanPowerSF’s full retail generation rate. CleanPowerSF’s retail generation Agenda Title: Approve CleanPowerSF Net Billing Plan Tariff Schedule Commission Meeting Date: September 8, 2026
rate recovers the cost to procure energy and to operate and staff the program. As a result, by receiving the full retail rate, customers on the NEM Tariff are compensated at a level that exceeds the simple cost of energy.
On January 27, 2026, staff proposed a Net Billing Tariff intended to ensure that CleanPowerSF procur es electricity in a more cost-effective manner for all ratepayers . Staff’s initial Net Billing Tariff proposal was based on the California Public Utilities Commission adopted Avoided Cost
Calculator (ACC), a statewide tool used by utilities and other community choice aggregators to quantify the
avoided cost value of measures that reduce electricity
demand on the grid.
Comments critiqued the use of the ACC because the ACC
linked CleanPowerSF’s Net Billing Tariff to the CPUC-
determined ACC values rather than locally determined
values. Opponents argued that the ACC undervalued
rooftop solar and the changing hourly values would be
difficult for participating customers to understand.
Following the Commission’s guidance, staff held additional meetings to further discuss the proposal with advocates and better understand their concerns. As a result, staff developed a different proposal.
B. Revised Proposal
Staff revised the proposal to anchor it in CleanPowerSF's retail rate and regular cost of service analysis. Like the NEM Tariff , the proposed Net Billing Tariff would use
CleanPowerSF’s retail generation rates to credit solar
energy exports . Unlike the NEM Tariff, the credits would exclude the non -energy supply portion of CleanPowerSF’s retail rate that recover the cost of running CleanPowerSF.
Staff’s revised proposal also simplifies the year-end true-up process by allowing customers to retain or cash out the full amount of their excess energy credits and eliminating Net Surplus Compensation.
Retail rates are comprised of costs to provide energy
generation
and capacity, as well as administrative and
operational expenses. Staff proposes that the Net Billing Tariff set energy export rates to be the customer’s retail generation rate less the percentage of that rate comprised of fixed costs because CleanPowerSF incurs administrative and operating costs for all customers including those
exporting energy to the grid through rooftop solar.
Agenda Title: Approve CleanPowerSF Net Billing Plan Tariff Schedule Commission Meeting Date: September 8, 2026
II. CleanPowerSF Net Billing Tariff Design
The proposed CleanPowerSF Net Billing Tariff includes the following rates for electricity that participating customers would consume from (import) or send (export) to the grid.
Import Rate: Electricity that r esidential and non- residential customers consume or “ import” from the grid will be
charged at CleanPowerSF’s applicable Commission-
adopted time-of-use retail rate schedule.
Export Credit Rate: Electricity that customers send to the grid will be credited at the customer’s applicable retail rate minus the non-energy related costs included in the rate.
Staff relied on the cost of service analysis conducted in the 2027 CleanPowerSF Rate Study to determine energy and
non-energy related costs.
The 2027 CleanPowerSF Rate Study foun d fixed costs
comprise approximately 15 percent of residential customer costs and 11 percent of non- residential customer costs.
Thus, the Export Credit Rate for Residential and non-
Residential customers will be approximately 85 percent and 89 percent of their rates, respectively.
The cost of service process is an industry -accepted
framework that allocates costs to each customer class
served by a utility. E lectric utility costs are typically characterized as either fixed or variable; fixed costs are those that do not change with the production of electricity, whereas variable costs are directly related to the amount of electricity produced and/or purchased. CleanPowerSF uses the Rate Study as the basis to determine how rates should be adjusted. Per City mandates, new Rate Studies are
completed every five years.
The fixed‑ cost percentage will be re‑ evaluated with each Rate Study as new Rate Studies are completed.
Annual True-Up:
The proposed CleanPowerSF N et Billing Tariff is designed to compensate customers for the energy they export at the cost CleanPowerSF would otherwise pay to procure that
power from the market. Based on this, c ustomers would be allowed to retain or cash out any export credits they earned but did not use by the end of the True-Up Period.
III. The Net Billing Tariff and its Relationship to the Net Energy Metering Tariff
Agenda Title: Approve CleanPowerSF Net Billing Plan Tariff Schedule Commission Meeting Date: September 8, 2026
Under the terms of the CleanPowerSF NEM Tariff adopted
by the Commission in Resolution No. 24- 0117, customers currently on PG&E’s Net Billing Tariff are being served under CleanPowerSF’s NEM Tariff, until the Commission
adopts a successor tariff. If the Commission adopts the proposed Net Billing Tariff , staff has also proposed
revisions to CleanPowerSF’s NEM Tariff that will remove the provision added by Resolution No. 24-0117. Customers who significantly modify their systems or reach the end of their 20-year Net Energy Metering legacy period will
subsequently be transitioned to and served under the new CleanPowerSF Net Billing Tariff.
IV. Proposed Revisions to CleanPowerSF Net
Energy Metering Tariff
The proposal makes cost-neutral changes to the existing CleanPowerSF NEM Tariff to clarify that it only applies to CleanPowerSF customers that are also PG&E NEM
customers. The changes also include non-substantive edits and a change to the True- Up and Settlement process for NEM customers that close their accounts. For NEM
customers that close their accounts, CleanPowerSF will conduct the True -Up and Settlement process.
CleanPowerSF will issue a check to customers with
remaining Net Surplus Compensation to the last billing
address for the customer. Attachment 1 includes underlines and strikethroughs to reflect the proposed changes to the current NEM tariff.
V. Public Outreach and Education
SFPUC staff engaged customers and the general public on the initial proposed CleanPowerSF Net Billing Tariff, called the Solar Billing Plan ,
through a variety of public meetings
and a public comment period. These included:
A. A November 2024 Listening Session with local San
Francisco solar installers.
B. A February 2025 Rooftop Solar Webinar for the
general public to learn more about rooftop solar and
where CleanPowerSF announce d its
intention to
explore a successor to our NEM Tariff.
C. The creation of a webpage dedicated to the Solar
Billing Plan proposal, as well as outreach to direct
customers to the website through a March 2025 Net
Energy Metering postcard.
D. A June 2025 workshop in which Staff released the
CleanPowerSF Solar Billing Plan proposal and
discussed the proposal with NEM customers and the
Agenda Title: Approve CleanPowerSF Net Billing Plan Tariff Schedule Commission Meeting Date: September 8, 2026
solar industry for questions and comments.
E. A written public comment period from June 25 to
July 16, 2025 during which S taff received written
comments on the proposal presented at the
workshop and listed on the website.
F. CleanPowerSF presented the initial proposal to the
Rate Fairness Board on November 4 and December
4, 2025 and January 16, 2026.
G. Staff presented the initial proposal to the
Commission on January 27, 2026. Following
guidance from the Commission, staff engaged in in-
depth discussions with solar advocates on March 25
and June 26, 2026. Staff presented the revised
proposal to the Rate Fairness Board on June 22,
2026. The Rate Fairness Board’s comment letter on
the proposal is provided. In their letter, the Rate
Fairness Board sai d they "find that the Staff’s
proposed Solar Billing Plan is fair and reasonable,
and recommend that the Commission approve it."
VI. Public Hearing Notice
Pursuant to Charter Section 16.112, a Notice of Public
Hearing on the establishment of a rate was published in the official newspaper on August 27, 2026
and posted on the
SFPUC website for a public hearing on September 8, 2026 , with possible Commission action on this date.
VII. Board of Supervisors Review
Pursuant to Charter Section 8B.125, Commission action
adopting rates and charges is subject to rejection by the Board of Supervisors within 30 days following notification .
Absent B oard of Supervisors rejection, these proposed CleanPowerSF rates will become effective October 9, 2026 and will remain effective until revised.

IV. True-up and Settlement Process
A. On an annual basis, CleanPowerSF will determine whether an eligible CleanPowerSF customer has remaining Export Credits from the True-Up Period. Generally, for new customers, the True-up Period for the first year will
cover the period starting on the date that the customer commenced service under this NBT Schedule through the customer’s April billing cycle. For those customers for whom CleanPowerSF has insufficient usage data to determine if the customer has remaining Export Credits, CleanPowerSF will perform the True-Up at a subsequent True-up Period when sufficient usage data is available.
B. Any Export Credits remaining in the Export Credit Balance at the time of True- Up will roll over to the next True-Up Period. Customers may instead elect to receive their remaining Export Credits by check. Customers electing to receive a check must indicate their preference within 60 days of the first bill following the end of the True-Up Period and can refer to instructions on CleanPowerSF’s website.
V. Termination of CleanPowerSF Service
A. If a CleanPowerSF customer opts-out of the CleanPowerSF program and returns to PG&E bundled service or otherwise closes their CleanPowerSF account, the customer may request CleanPowerSF to conduct the True-Up and Settlement process as detailed in Section IV. CleanPowerSF will issue a check to customers with remaining Export Credits to the billing address or one provided by the customer.
CLEANPOWERSF
ELECTRIC SCHEDULE NEM-CLEANPOWERSF
Net Energy Metering
I. Applicability
A. Applicable to enrolled CleanPowerSF customers with a Renewable Electrical Generation Facility.
B. The customer must be on a Pacific Gas and Electric Company’s (PG&E) net energy metering Electric Tariff Schedule, including NEM, NEM2, or other NEM programs (PG&E NEM Tariffs).
II. Definitions
A. “True-Up Period”
The True-Up Period typically is the twelve-month period commencing with the May bill of each year and ending with the April bill of the following year. For eligible CleanPowerSF customers with less than 12 months of service under this tariff, the True -up Period commences with the earliest date when the customer was both a CleanPowerSF customer and taking service on PG&E’s net energy metering tariff schedule and ending with the following April bill.
B. “Net Electricity Consumer”
A NEM -CleanPowerSF customer that produces less electricity from its Renewable Electrical Generation Facility during the True- up Period than is delivered by CleanPowerSF to the customer during the same period.
C. “Net Electricity Generator”
A NEM -CleanPowerSF customer that produces more electricity from its Renewable Electrical Generation Facility during the True- up Period than is delivered by CleanPowerSF to the customer during the same period.
D. “Renewable Electrical Generation Facility”
A facility that generates electricity from a renewable source listed in California Public Resources Code Section 25741(a)(1)1 and that is:
1. Located on the customer’s owned, rented, or leased premises;
2. Equal to or less than 1 MW (AC) in capacity;
3. Interconnected for parallel operation with the PG&E distribution system; and
4. Sized principally to offset part or all the customer’s own on-site electrical requirements.
E. “Net Surplus Compensation”
The value for any Exported Electricity in excess of Imported Electricity during the True-Up Period.
F. “Otherwise-Applicable CleanPowerSF Rate Schedule”
The rate schedule that applies to a customer account for terms and conditions not determined by this tariff.
III. Rates and Billing
A. Each NEM-CleanPowerSF customer will receive a monthly billing statement reflecting net electricity consumption/production, charges incurred, credits generated during the current billing period, and remaining credits from previous billing cycles. If during a monthly billing cycle, the quantity of electricity produced by the customer’s Renewable Electrical Generation Facility and delivered to CleanPowerSF is greater than the quantity of electricity delivered to the customer by CleanPowerSF, the customer will receive a bill credit for the excess kilowatt-hours (kWh) produced.
1. For Customers on an Otherwise-Applicable CleanPowerSF Rate Schedule of E-1, the customer will receive a bill credit for the excess kilowatt -hours (kWh) produced. The value of the excess kWh produced shall be calculated according to the electricity usage charges of the customer’s otherwise-applicable CleanPowerSF rate schedule.
2. For customers on an Otherwise- applicable CleanPowerSF rate schedule other than E-1, the value of the excess kWh produced shall be calculated based on the applicable TOU rate when the excess kWh were produced. If the value of excess kWhs produced exceeds the sum of CleanPowerSF electric generation charges, across all applicable TOU periods during the billing cycle, the customer will receive a bill credit in the amount of the excess value.
B. All CleanPowerSF charges under the customer’s otherwise applicable rate schedule shall be in effect and all charges shall be due and payable on the due date identified in each billing statement.
1 An eligible facility is one that generates electricity by using one of the following methods: biomass; solar thermal; solar photovoltaic; wind; geothermal; fuel cells using renewable fuels; qualifying small hydroelectric generation; digester gas; municipal solid waste conversion; landfill gas; ocean wave; ocean thermal; or tidal current.
C. Residential and small commercial NEM-CleanPowerSF customers may elect to receive Annual Billing, under which CleanPowerSF charges for the preceding True-Up Period become due once per year, after the True-Up (see Section IV below). Eligible small commercial customers are defined as those having a maximum monthly peak demand of less than 20 kilowatts.
D. Any bill credits reflected on the customer’s bill will be carried over for use in subsequent billing period(s) during the same True-up Period in which they are accrued until such credits are exhausted or reset pursuant to the “True-Up and Settlement” process below.
IV. True-Up and Settlement Process
A. On an annual basis, CleanPowerSF will determine whether a participating customer is a Net Electricity Consumer or a Net Electricity Generator during the True-up Period. Generally, for new customers, the True-Up Period for the first year will cover the period starting on the date that the customer commenced service under this NEM Schedule through the customer’s April billing cycle. For those customers for whom CleanPowerSF has insufficient usage data to implement a True-Up, CleanPowerSF will perform the True-Up at a subsequent True-up Period when sufficient usage data is available.
B. For Net Electricity Consumers and Net Electricity Generators at the end of the True-up Period, any bill credit balances remaining at that time will be reset to zero for the beginning of the next True-Up Period.
C. If the customer is a Net Electricity Generator at the end of the True-Up Period, the customer is eligible to receive Net Surplus Electricity Compensation for any Exported Electricity in excess of the Imported Electricity over the True Up Period.
D. For a Net Electricity Generator, Net Surplus Compensation ($) is determined by multiplying the kilowatt-hours of net Exported Electricity during the True-up Period by the Net Surplus Compensation rate:
Name Rate
Net Surplus
Compensation
$0.0893/kWh
E. Net Surplus Compensation will be applied as credits for future CleanPowerSF charges. Customers may instead elect to receive their Net Surplus Compensation by check. Customers electing to receive a check must indicate their preference within 60 days of the first bill following the end of the True-Up Period and can refer to instructions on CleanPowerSF’s website.
F. Per California Public Utilities Code Section 2827(h)(4)(B), aggregated NEM customers are “permanently ineligible to receive net surplus electricity compensation.” Thus, CleanPowerSF
aggregated NEM accounts are
ineligible to receive Net Surplus Compensation.
V. Termination of CleanPowerSF Service
A. If a NEM-CleanPowerSF customer opts-out of the CleanPowerSF program and returns to PG&E bundled service, or otherwise closes their CleanPowerSF account, the customer may request CleanPowerSF to settle any remaining net generation credits on the account, following the True-Up and Settlement process as defined in Section IV above. CleanPowerSF will issue a check to customers with remaining Net Surplus Compensation to the
address or one provided by the customer.
I hereby certify that the foregoing resolution was adopted by the San Francisco Public Utilities Commission at its meeting of September 8, 2026.

A NEM-CleanPowerSF customer that produces less electricity from its Renewable Electrical Generation Facility during an Annual the True-up Period than is delivered by CleanPowerSF to the customer during the same period.
C. “Net Electricity Generator”
A NEM -CleanPowerSF customer that produces more electricity from its Renewable Electrical Generation Facility during an Annual the True-up Period than is delivered by CleanPowerSF to the customer during the same period.
D. “Renewable Electrical Generation Facility”
A facility that generates electricity from a renewable source listed in California Public Resources Code Section 25741(a)(1)61 and that is:
1. Located on the customer’s owned, rented, or leased premises;
2. Equal to or less than 1 MW (AC) in design capacity;
3. Interconnected for parallel operation with the PG&E distribution system; and
4. Sized principally to offset part or all the customer’s own on-site electrical requirements.
E. “Net Surplus Compensation”
The value for any Exported Electricity in excess of Imported Electricity during the True- up Period.
F. “Otherwise-Applicable CleanPowerSF ServiceRate Schedule” The rate schedule that applies to a customer account for terms and conditions not determined by this tariff.
III. Rates and Billing Rates, Billing and Annual True-Up Process A. Rates and Monthly Billing for CleanPowerSF Service
A. Each NEM-CleanPowerSF customer will receive a monthly billing statement reflecting net electricity consumption/production, charges incurred, credits generated during the current billing period, and remaining credits from previous billing cycles. The monetary value of any excess production during a monthly billing cycle shall be calculated as follows: or Customers on a Flat Rate Tariff: If during a monthly billing cycle, the quantity of electricity produced by the customer’s Renewable Electrical Generation Facility and delivered to CleanPowerSF is greater than the quantity of electricity delivered to the customer by CleanPowerSF, the customer will receive a bill credit for the excess kilowatt- hours (kWh) produced.
1. For Customers on an Otherwise -Applicable CleanPowerSF Rate Schedule of E -1, the customer will receive a bill credit for the excess kilowatt- hours (kWh) produced. The value of the excess kWh produced shall be calculated according to the electricity usage charges of the customer’s otherwise-applicable CleanPowerSF rate schedule.
1 An eligible facility is one that generates electricity by using one of the following methods: biomass; solar thermal; solar photovoltaic; wind; geothermal; fuel cells using renewable fuels; qualifying small hydroelectric generation; digester gas; municipal solid waste conversion; landfill gas; ocean wave; ocean thermal; or tidal current.

2. For Customers on a Time of Use (“TOU”) Tariff: If during any TOU period, the quantity of electricity produced by the customer’s Renewable Electrical Generation Facility and delivered to CleanPowerSF is greater than the quantity of electricity delivered to the customer by CleanPowerSFFor customers on an Otherwise -applicable CleanPowerSF rate schedule other than E -1, the value of the excess kWh produced shall be calculated based on the applicable TOU rate when the excess kWh were produced. If the value of excess kWhs produced exceeds the sum of CleanPowerSF electric generation charges, across all applicable TOU periods during the billing cycle, the customer will receive a bill credit in the amount of the excess value.
B. All CleanPowerSF charges under the customer’s otherwise applicable rate schedule shall be in effect and all charges shall be due and payable on the due date identified in each billing statement.
C. Residential and small commercial NEM-CleanPowerSF customers may elect to receive Annual Billing, under which CleanPowerSF charges for the preceding Annual True-Up Period become due once per year, after the Annual True-Up (see Section IV.B below).
Eligible small commercial customers are defined as those having a maximum monthly peak demand of less than 20 kilowatts.
D. A
ny bill credits reflected on the customer’s bill will be carried over for use in subsequent billing period(s) during the same Annual True-up Period in which they are accrued until such credits are exhausted or reset pursuant to the “Annual True-Up and Settlement” item 2process below.
IV. Annual True-Up and Settlement Process
A. On an annual basis, CleanPowerSF will determine whether a participating customer is a Net Electricity Consumer or a Net Electricity Generator during the preceding Annual True-up Period. Generally, for new customers, the Annual True-up Period for the first year will cover the period starting on the date that the customer commenced service under this NEM Schedule through the customer’s April billing cycle. For those customers for whom CleanPowerSF has insufficient usage data to implement a True Up, CleanPowerSF will perform the True Up at a subsequent Annual True-up Period when sufficient usage data is available.
B. F or Net Electricity Consumers and Net Electricity Generators at the end of the Annual True-up Period, any bill credit balances remaining at that time will be reset to zero for the beginning of the next True-Up Period.
C. If the customer is a Net Electricity Generator at the end of the Annual True-up Period, the customer is eligible to receive Net Surplus Electricity Compensation for any net electricity production calculated Exported Electricity in excess of the Imported Electricity over the prior twelve-months True Up Period.
D. For a Net Electricity Generator,The Net Surplus Electricity Compensation rate for each ($) is determined by multiplying the kilowatt-hourhours of net electricity production Exported Electricity during the True-up Period by the Net Surplus Compensation rateis:

E. CleanPowerSF will provide Net Electricity Generators their Net Surplus Electricity Compensation at the end of the Annual True-Up Period by bill credit that will apply towill be applied as credits for future CleanPowerSF charges. Customers may instead elect to receive their Net Surplus Electricity Compensation by check. Customers electing to receive a check must indicate their preference within 60 days of the first bill following the end of the Annual True-Up Period, and can refer to instructions on CleanPowerSF’s website.
F. Per California Public Utilities Code Section 2827(h)(4)(B), aggregated NEM customers are “permanently ineligible to receive net surplus electricity compensation.” Thus, CleanPowerSF
aggregated NEM accounts are ineligible to receive Net Surplus Compensation.
G. Renewable Energy Credits and Environmental Attributes. The customer will retain ownership of all RECs and environmental attributes associated with its usage of electricity produced by the eligible Renewable Electrical Generation Facility.
V. Termination of CleanPowerSF Service
A. If a NEM-CleanPowerSF customer opts-out of the CleanPowerSF program and returns to PG&E bundled service, or otherwise closes their CleanPowerSF account, that the customer may request that CleanPowerSF to settle any remaining net generation credits on the account, provided thatfollowing the request is received within 90 calendar days of the return to PG&E service or the account closure. For customers with remaining net bill credit balances credits, True-Up and Settlement process as defined in Section IV above.
CleanPowerSF will issue a check to customers with remaining Net Surplus Compensation to the address or one provided by the customer.for the amount of any net bill credit balances remaining at the time of the return to PG&E service or the account closure.
