2025 Resource Adequacy Plan
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 2025,” 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. The CAISO, as the
balancing authority, has the responsibility 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.

2025 Resource Adequacy Plan
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
Vernon’s monthly coincident peak Demand Forecast consists of the following three
steps:
1.Establish Monthly Vernon System Peak Demand Forecast for 2024
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 inconsistent trend year over year between
2020 and 2024. Closer review of Exhibit 1 reveals that more recently, the growth
rate from 2022 to 2024 decreased by 3.3%. Based on the current load trend and
recent years of inconsistencies, Staff concluded zero load growth adjustment is an
appropriate forecast for calendar year 2025. Exhibit 2 shows the determination of
the projected system peak demand for 2025 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.
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 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 2025. 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

2025 Resource Adequacy Plan
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:
A Load Serving Entity 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 agreement with a customer. The eight following resources are
among those that meet this criterion and provide Qualifying Capacity. The
calculation for the amount of Qualifying Capacity for the eight eligible resource types
are 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 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 the 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 the 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.

2025 Resource Adequacy Plan
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
CAISO on the path associated with the System Resource. Firm transmission
rights provide 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 the
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 the 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 list enough local resources in its Resource Adequacy data
templates to satisfy its obligation. Staff has prepared the Resource Adequacy data
templates (Exhibit 4) which lists 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

2025 Resource Adequacy Plan
with the City’s electric customers shall count towards the City’s Local Capacity’s
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 increase and has created
an increase in 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 2025, the CAISO has determined the system-wide Flexible Capacity
needs and has notified each LSE their monthly requirement. Exhibit 7 lists the City’s
Flexible Capacity requirement by month and category. Furthermore, the 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 2025, the 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 it will rely on to satisfy its Flexible Resource Adequacy
Capacity on both the annual and monthly Resource Adequacy data templates.
Staff has 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.

2025 Resource Adequacy Plan
Annual and Monthly Resource Adequacy and Supply data:
The CAISO Tariff requires that the scheduling coordinator of a load serving entity
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 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 has 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 a load-serving entity and
a scheduling coordinator for resource adequacy resources, must submit a Resource
Adequacy and Supply Plan on the set schedules. Staff has prepared the Annual
Resource Adequacy (Exhibit 5) and Supply data (Exhibit 6 & 7) for the calendar year
2025. 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 all 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.

City Council Agenda Report
Meeting Date:October 15, 2024
From:Todd Dusenberry, General Manager of Public Utilities
Department:Public Utilities
Submitted by:Adriana Ramos, Senior Management Analyst
Subject
Resource Adequacy Plan for 2025
Recommendation
A. Adopt Resolution No. 2024-022 approving and adopting the Vernon Public Utilities
Department Resource Adequacy Plan for 2025, 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 and approving
the resources used to satisfy the California Independent System Operator’s (CAISO) tariff
requirements and repealing Resolution No. 2023-21; and
B. Authorize staff to submit the Vernon Public Utilities Department’s Resource Adequacy Plan
for 2025 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 ensuring 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 analysis, no load growth adjustment is appropriate for 2025. To establish
the Coincident Peak Demand Forecast for 2025, staff has used its monthly peak Demand
Forecast (as listed in Table 1 of the Resource Adequacy Plan for 2025) 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 2025.
(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 from 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 of 5 years or longer. The Qualifying Capacity
will be based on the City of Vernon’s percentage share of the Net Qualified
Capacity (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 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) 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 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 set schedule 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 2025 and now seeks authorization from the
City Council to submit the Plan and the Monthly Resource Adequacy and Supply data to the
CAISO.
