EXHIBIT A
Resolution No. 2026-040
________________________
Background:
The Resource Adequacy (RA) provisions of the California Independent System Operator’s (CAISO) tariff require the Scheduling Coordinator (SC) of a Load Serving Entity (LSE), such as the City of Vernon, to establish and submit the following information upon approval from its Local Regulatory Authority:
1. Coincident Peak Demand Forecast for its load,
2. Planning Reserve Margin,
3. Qualifying Capacity Criteria that will be used for determining qualifying resource types and the Qualifying Capacity from such resources,
4. an annual/monthly RA and supply data, and
5. a list of resources used to satisfy the LSE’s Local Capacity Requirement and Flexible Resource Adequacy Capacity Requirement.
Staff has prepared the attached “City of Vernon Public Utilities Department’s Resource Adequacy Plan for Calendar Year 2027,” which is consistent with the CAISO Tariff requirements. The following is a discussion of each of the CAISO Tariff requirements and how the City will meet each requirement.
Coincident Peak Demand Forecast:
Vernon’s municipal load resides within the CAISO control area. CAISO, as the balancing authority, is responsible for meeting reliability criteria established by the Western Electricity Coordinating Council (WECC). As such CAISO has entered into agreements with various market participants, Generators, Scheduling Coordinators, Participating Transmission Owners, Utility Distribution Companies, and Metered Subsystems (MSS), which impose certain responsibilities on parties to establish a reliable system. One of those responsibilities is to have operating reserves that meet the WECC minimum requirements.
The CAISO’s goal in considering reserve requirements is to balance available capacity with demand across the entire CAISO control area, and therefore, CAISO’s primary concern is with the time and amount of peak demand on the CAISO controlled transmission system (the “system peak”). In order to reduce demand during the period of the system peak (and therefore, to lower the peak demand on the transmission system), utilities generally offer retail rate structures designed to encourage load shifting away from the on-peak period. Such efforts are intended to achieve on-peak demand reduction and lower the need to build new generation to meet peak demand. Vernon has adopted a rate structure that has successfully shifted the peak demand period for Vernon’s system to a time that is generally earlier than the time of the CAISO system peak.
Vernon’s share of the capacity needed to meet CAISO’s control area capacity requirements may be established by determining the amount of Vernon’s load that contributes to the CAISO system peak. Vernon’s load that contributes to the CAISO system peak is the City of Vernon coincident peak Demand. The process to establish 2027 Resource Adequacy Plan

________________________
Vernon’s monthly coincident peak Demand Forecast consists of the following three steps:
1. Establish Monthly Vernon System Peak Demand Forecast for 2027 To establish the City of Vernon’s system peak demand forecast, Staff performs an analysis on annual changes in the City’s energy demand peaks during a five-year period. Based on the results of the analysis, Staff forecasts a load growth rate for the upcoming calendar year (Exhibit 1). This year’s analysis of the City of Vernon’s system peak demand demonstrates an inconsistent trend year after year between 2022 and 2026. Closer review of Exhibit 1 reveals that more recently, the growth rate from 2023 to 2026 decreased by 0.4%. Based on the current load trend and recent years of inconsistencies, Staff concluded that a zero-load growth adjustment is an appropriate forecast for calendar year 2027. Exhibit 2 shows the determination of the projected system peak demand for 2027 based on no load growth adjustment. The projected system peak demand for the City of Vernon is shown below in Table 1.

2. Establish Coincidental Peak Factor
The coincidental peak factor is the percentage of the City of Vernon’s energy demand at the time of the CAISO system peak demand. As set forth in Section 40 of the CAISO Tariff, the coincidental peak factor for each month has been calculated and provided to the City annually by the California Energy Commission (CEC). The monthly coincidental peak factor is shown in column C of Exhibit 3. 2027 Resource Adequacy Plan

Resolution No. 2026-040
________________________
3. Calculate Monthly Coincident Peak Demand Forecast
The City of Vernon’s Coincident Peak Demand forecast is calculated as the mathematical product of the City of Vernon’s forecasted System peak demand and the coincidental peak factor. This reflects the City of Vernon’s projected demand at the time of the CAISO system’s peak demand for each month. The monthly Coincident Peak Demand Forecast is calculated and listed in column D of Exhibit 3 for the period of January through December 2027. It is also shown below in Table 2.

Planning Reserve Margin:
The Planning Reserve Margin is the amount of Resource Adequacy Capacity that an LSE must maintain above its coincident peak Demand Forecast. Historically, the City of Vernon has established its Planning Reserve Margin at 15%. Staff recommends that the City Council maintain the Planning Reserve Margin at 15%. The 15% Planning Reserve Margin is used to establish the monthly Resource Adequacy obligation for the City of Vernon as listed in column E of Exhibit 3.
Qualifying Capacity:
An LSE must provide the CAISO with a description of the criteria that will be used to determine the type of resources that can be used to meet its capacity obligation and the amount of capacity (Qualifying Capacity) from such resources. Historically, Vernon has used the following criterion to determine whether a resource qualifies: It qualifies if Vernon has a contractual right to the power or has an interruptible service 2027 Resource Adequacy Plan
4 of 20
Resolution No. 2026-040
________________________
agreement with a customer. The following eight resources are among those that meet this criterion and provide Qualifying Capacity. The eligible Qualifying Capacity for the eight applicable resource types is as follows:
1. CAISO IST-enabled Product. Power supply contract/s entered through WSPP Agreement (MRTU Amendment) and defined as any SC-to-SC traded product for which an IST (Inter-SC Trades) can be submitted and for which CAISO will make payment or issue an invoice, including Energy, Tier I IFM Bid Cost Recovery Obligations, and Ancillary Service Obligation trades, as each is defined in the Tariff.
2. Palo Verde. Vernon Purchase Power Contract with SCPPA for 4.9% of SCPPA’s share of Palo Verde Nuclear Generating Station (Palo Verde) shall be eligible as Qualifying Capacity. The power is scheduled as an import generally at Westwing Substation through CAISO’s entitlement of transmission from Westwing to SP-15.
3. Boulder Canyon. Contract NO 16-DSR-12650 between United States Department of Energy Western Area Power Administration Boulder Canyon Project and City of Vernon, California for Electric Service shall be eligible to count as Qualifying Capacity. The power is scheduled as an import at Mead Substation generally through CAISO’s entitlement of transmission from Mead Substation to SP-15. The amount of Qualifying Capacity will be based on the most current schedule for the available capacity from the Boulder Canyon Project at the time of submittal of the Resource Adequacy Plan.
4. Vernon Units. Generating units and system units (excluding Vernon diesel generating units) within Vernon’s MSS, including the Malburg Generating Station and the City-owned H. Gonzales units, as reflected in Schedule 14 of Vernon’s MSS Agreement with CAISO shall be eligible to count as Qualifying Capacity. The amount of Qualifying Capacity of such units shall not exceed the Net Qualifying Capacity (NQC) as determined and listed annually by the CAISO.
5. Long-Term Power Purchase Contracts. Long-term power supply contracts (5 years or greater) entered through a power purchase agreement shall be eligible to count as Qualifying Capacity. The amount of Qualifying Capacity will be based on the City of Vernon’s percentage share of the Net Qualifying Capacity of each contract. For the upcoming year, the following contracts will count as Qualifying Capacity, Antelope DSR 1 Solar Project, Astoria 2 Solar Project, Daggett Solar Project and Puente Hills Landfill Gas-To-Energy Facility.
6. Other Units. All other capacity from a Participating Generator, a System Unit, or a System Resource, as defined in the CAISO Tariff, shall be eligible as Qualifying Capacity. System Resources, however, must be located in the CAISO control area or have a firm transmission path from source to the CAISO control area. Such criteria for firm transmission facilities over the CAISO control area can be satisfied with the possession of a firm transmission right from the 2027 Resource Adequacy Plan

Resolution No. 2026-040
________________________
CAISO on the path associated with the System Resource. Firm transmission rights provide a physical priority right to schedule over congested paths.
7. Interruptible Service Agreements. Interruptible Service Agreements with the City’s Electrical customers. Currently, Vernon has an Interruptible Service Agreement where the customer agrees to interrupt up to 27 MW of load within a 30-minute notification. A period of interruption can occur upon notification from the Independent System Operator (ISO) requiring the City to shed load or upon the unscheduled outage of the Malburg Generating Station (MGS) or any other generating unit internal to the City’s system.
8. Battery Energy Storage System (Non-Generator Resources). Power Supply contracts for BESS or Non-Generator Resource, as defined by the CAISO, entered through a power purchase agreement, shall be eligible to count as Qualifying Capacity. The amount of Qualifying Capacity shall be based on Vernon’s percentage share of the Net Qualifying Capacity of each contract.
Local Capacity Area Resources:
In accordance with Section 40.3 of the CAISO Tariff, CAISO annually publishes a Local Capacity Technical Study that determines the amount of local capacity needed in the Los Angeles Basin area that must be available to CAISO. Based on the Local Capacity Technical Study, the CAISO allocates responsibility for Local Capacity Area Resources to the Scheduling Coordinators of the LSEs. The CAISO validates that the Scheduling Coordinator lists enough local resources in its Resource Adequacy data templates to satisfy its obligation. Staff have prepared the Resource Adequacy data templates (Exhibit 4), which list the Resource Adequacy Resources, including the Malburg Generating Station, Puente Hills Landfill Gas-To-Energy Facility, and the Cityowned H. Gonzales units that will be counted on to satisfy the Local Area Capacity requirement for the City of Vernon. Additionally, any Interruptible Service Agreements with the City’s electric customers shall count towards the City’s Local Capacity requirement.
Flexible Resource Adequacy Capacity:
In accordance with Section 40.10 of the CAISO Tariff, CAISO annually conducts a study to determine the Flexible Capacity Need for the CAISO Balancing Authority Area for each month of the next calendar year and provides the results of the study to each Local Regulatory Authority in the CAISO Balancing Authority Area. Flexible resources are resources with the potential to ramp up and down quickly and have the capability to start and shut down multiple times per day. The need for flexible capacity is a result of the CAISO managing a “greener” grid. The increase of variable energy resources and distributed generation has presented significant challenges to grid reliability. These types of resources have continued to grow and have increased supply and load variability and unpredictability within the CAISO system. In order for the CAISO to efficiently operate the grid, it needs measures to ensure that flexible resources are economically bid into the CAISO markets so that they may be optimally dispatched.

________________________
The CAISO study calculates the total system amount of Flexible Capacity needed for each of the three Flexible Capacity categories: (1) Base ramping flexibility; (2) Peak ramping flexibility; and (3) Super-peak ramping flexibility. Section 40.10.3 of the CAISO Tariff sets the criteria needed by resources to qualify for each category. For the Calendar Year 2027, CAISO has determined the system-wide Flexible Capacity needs and has notified each LSE of their monthly requirement. Exhibit 7 lists the City’s Flexible Capacity requirement by month and category. Furthermore, CAISO has established the Effective Flexible Capacity for each resource and the category of Flexible Capacity each resource will qualify for the upcoming compliance year. For Calendar Year 2027, CAISO has established 105 MW of category 1 base ramping flexible resources adequacy capacity for Malburg Generating Station, and 5.75 MW category 1 base ramping flexible resource adequacy capacity for both H. Gonzales Units (Exhibit 8). CAISO Tariff Section 40.10.5.1 requires the Scheduling Coordinators of LSEs to identify the resources they will rely on to satisfy their Flexible Resource Adequacy Capacity on both the annual and monthly Resource Adequacy data templates.
Staff prepared the Resource Adequacy data templates (Exhibit 4), which list the Resource Adequacy Resources, including the Malburg Generating Station and the City-owned H. Gonzales units, that will be counted on to satisfy the Flexible Resource Adequacy Capacity requirement for the City of Vernon.
Annual and Monthly Resource Adequacy and Supply data:
The CAISO Tariff requires that the scheduling coordinator of an LSE provide an annual and a monthly Resource Adequacy Plan (Section 40.2.2.4) using the required templates and submitted on the set schedules. Furthermore, the scheduling coordinator of a resource providing resource adequacy must submit both an annual and monthly Supply Plan (Section 40.4.7.1) using the required templates and submitted on the set schedules.
Staff asks that City Council adopt the following two requirements for both the annual and monthly Supply Plan submittals:
1. Annual: submittals must demonstrate that 90% of the forecasted coincident peak demand plus planning reserves margin and flexible resource adequacy requirement has been secured; and 100% of the total local resource adequacy requirement has been secured.
2. Monthly: submittals must demonstrate 100% of the forecasted coincident peak Demand plus planning reserves margin, flexible resource adequacy requirement, and local resource adequacy requirement have been met. Data on the monthly plans may be adjusted for seasonal variations in the City’s load or changes in its contracted/owned resources.
Therefore, as required by the CAISO, the City of Vernon, as an LSE and a scheduling coordinator for resource adequacy resources, must submit a Resource Adequacy 2027 Resource Adequacy Plan

Resolution No. 2026-040
________________________
and Supply Plan on the set schedules. Staff prepared the Annual Resource Adequacy (Exhibit 5) and Supply data (Exhibit 6 & 7) for calendar year 2027. Staff will submit the monthly Resource Adequacy and Supply data to the CAISO as they become due.
The data to be submitted on the monthly plans will demonstrate that 100% of applicable requirements have been met and may be adjusted from the annual Resource Adequacy and Supply Plan for seasonal variations, as well as load and resource changes. The monthly plan is due to the CAISO 45 days prior to the beginning of the month.
