____________________
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 2026,” 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
2026 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 202
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 over year between
2021 and 2025. Closer review of Exhibit 1 reveals that more recently, the growth
rate from 2022 to 2025 decreased by 4.1%. 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 2026. Exhibit 2 shows the
determination of the projected system peak demand for 2026 based on no load
growth adjustment. The projected system peak demand for the City of Vernon is
shown below in Table 1.

December 149.46
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.

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 2026. It is also shown
below in Table 2.

July 127.8
August 132.6
September 139.2
October 132.8
November 122.6
December 121.0
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
2026 Resource Adequacy Plan
Page 4 of 20
Resolution No. 2025-028
Page 8 of 24
____________________
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. Gonzalez 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
2026 Resource Adequacy Plan

Resolution No. 2025-028
Page 9 of 24
____________________
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 City-
owned H. Gonzalez 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 2026, 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 2026, 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. Gonzalez 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
2026 Resource Adequacy Plan

____________________
and Supply Plan on the set schedules. Staff prepared the Annual Resource Adequacy
(Exhibit 5) and Supply data (Exhibit 6 & 7) for calendar year 2026. 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.

Subject
Resource Adequacy Plan for 2026
Recommendation
A. Adopt Resolution No. 2025-028 approving and adopting the Vernon Public Utilities
Department Resource Adequacy Plan for 2026, which includes the Coincident Peak Demand
Forecast, the Planning Reserve Margin, the Qualifying Capacity Criteria, and the Qualifying
Capacity from such resources, the City’s Resource Adequacy and Supply Data, approving the
resources used to satisfy the California Independent System Operator’s (CAISO) tariff
requirements, and repealing Resolution No. 2024-022; and
B. Authorize staff to submit the Vernon Public Utilities Department’s Resource Adequacy Plan
for 2026 and the Monthly Resource Adequacy and Supply Data to the CAISO.
Background
As the electric grid operator for the State, the California Independent System Operator (CAISO)
is responsible for maintaining a reliable electric grid. One of the keys to maintaining a reliable
grid is to ensure that the electric system has adequate resources to meet its electric demand. To
do this, the CAISO has established provisions in its Tariff to ensure that Load Serving Entities
(LSE), such as the City of Vernon (City), will secure sufficient resources to meet their customers’
energy demands.
Pursuant to Section 40 of the CAISO Tariff, LSE must annually provide a Resource Adequacy
demonstration or plan to the CAISO. The Resource Adequacy demonstration must include: (1) a
Coincident Peak Demand Forecast, (2) Reserve Margin, (3) Qualifying Capacity Criteria, (4)
annual and monthly Resource Adequacy and Supply Data, (5) a list of Resource Adequacy
Resources that will be counted on to satisfy its Local Capacity Requirement and (6) Flexible
Resource Adequacy Capacity Requirement. The Resource Adequacy demonstration categories
are each defined and described in detail below.
(1) Coincident peak Demand Forecast is defined as the amount of the City’s load contributing to
the CAISO system peak. This is calculated by first establishing a monthly peak Demand Forecast
for the upcoming year and applying a projected load growth rate, if appropriate. Based on staff’s
analysis of actual data, no adjustment is deemed necessary for 2026. To establish the Coincident
Peak Demand Forecast for 2026, staff used its monthly peak Demand Forecast (as listed in Table
1 of the Resource Adequacy Plan for 2026) and multiplied it by the coincident peak factor
provided by the California Energy Commission. The results of this calculation are the Coincident
Peak Demand Forecast and are listed in Table 2 of the Resource Adequacy Plan for 2026.
(2) Planning Reserve Margin is defined as the amount of Resource Adequacy Capacity an LSE
must maintain above its coincident peak Demand Forecast. The Electric Utility governing board,
Vernon City Council, has established its Planning Reserve Margin at 15%.
(3) Qualifying Capacity Criteria is the criteria used to determine the type of resources that can be
used to meet an LSE’s capacity obligation and the amount of capacity (Qualifying Capacity) from
such resources. The City has elected to use the following resources to meet its capacity needs
and the qualifying capacity of each of them:
a. Power supply contract(s) entered through Western Systems Power Pool (WSPP)
Agreement, Market Redesign and Technology Upgrade (MRTU) Amendment, and any
product defined as a Scheduling Coordinator (SC)-to-SC traded product for which an Inter-
SC Trade (IST) can be submitted to the CAISO.
b. Vernon Purchase Power Contract with the Southern California Public Power Authority
(SCPPA) for the SCPPA’s share of the Palo Verde Generating Station. The qualified
capacity shall be 4.9% of SCPPA’s share of the Palo Verde Generating Station.
c. The contract between the United States Department of Energy Western Area Power
Administration Boulder Canyon Project, and the City of Vernon. The Qualifying Capacity
will be based on the most current schedule for the available capacity from the Boulder
Canyon Project.
d. The generating units and system units within the City’s electric system. The amount of
Qualifying Capacity of such units shall not exceed the Net Qualifying Capacity (NQC) as
determined and listed annually by the CAISO.
e. Long-term power purchase contracts for five years or longer. The Qualifying Capacity will
be based on the City of Vernon’s percentage share of the NQC for each contract, as
determined and listed annually by CAISO.
f. Capacity from a Participating Generator, System Unit, or System Resource as defined in
the CAISO Tariff.
g. Interruptible Service agreements between the City of Vernon and its electrical customers.
The Qualifying Capacity will be based on the contracted amount that the electrical
customer has agreed to interrupt.
h. Battery Energy Storage System (BESS)/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 the NQC value as determined and
listed annually by the CAISO and the City of Vernon’s percentage share of NQC for each
contract.
(4) Local Capacity Requirement is defined as the monthly allocation of the local capacity (Los
Angeles Basin) that the City must make available to the CAISO and demonstrated in the CAISO-
approved Resource Adequacy data templates. Resources located in the Los Angeles Basin area
shall count toward the City’s local capacity requirement.
(5) Flexible Resource Adequacy Capacity Requirement is defined as the monthly allocation of
the Flexible Resource Adequacy Capacity Requirement that the City must make available to the
CAISO and demonstrated in the CAISO-approved Resource Adequacy data templates. Flexible
resources are resources that can ramp up and down quickly and have the potential to start and
shut down multiple times per day (i.e., flexible capacity). The Malburg Generating Stations and
the City-owned H. Gonzales units shall count towards the City’s flexible capacity requirement.
(6) Annual and monthly Resource Adequacy and Supply data - must be submitted to the CAISO
on the established templates and the scheduled dates. The Resource Adequacy data templates
shall identify all qualified resources committed to meeting the City’s Resource Adequacy
obligations and the adopted Reserve Margin. Annual Resource Adequacy Plans data must
demonstrate that 90% of the Coincident Peak Demand Forecast plus planning Reserve Margin
and Flexible Resource Adequacy Capacity Requirement has been secured, and 100% of the
total local Resource Adequacy requirement has been secured. Monthly Resource Adequacy and
Supply data templates must demonstrate that 100% of the Coincident Peak Demand Forecast
plus planning Reserve Margin, Flexible Resource Adequacy Capacity Requirement, and local
Resource Adequacy requirement have been met. Monthly Resource Adequacy and Supply data
may be adjusted for seasonal variations in the City’s load or changes in its contracted/owned
resources.
Consistent with the CAISO Tariff requirements, staff has prepared the City of Vernon Public
Utilities Department Resource Adequacy Plan for 2026 and now seeks authorization from the
City Council to submit the Plan and the Monthly Resource Adequacy and Supply data to the
CAISO.
