Public Utility District m
MEETING DATE: November 6, 2024
TO: Board of Directors
FROM: Jared Carpenter, Electric Utility Director
SUBJECT: Consideration of Adopting Resolution 2024-20 Approving the
Submission and Attesting to the Veracity of the 2023 Power Source
Disclosure Report and Power Content Label.
APPROVED BY:
Brian C. Wright, General Manager
RECOMMENDATION:
Adopt Resolution 2024-20 approving the submission and attesting to the veracity of the
2023 Power Source Disclosure Report and Power Content Label.
BACKGROUND:
California Senate Bill (SB) 1305, approved in 1997, directs all California retail suppliers
of electricity to disclose to consumers the sources of energy used to provide the electric
service in an accurate and easy to understand manner. The SB 1305 Report is better
known as the Power Source Disclosure (PSD) Report. The District submits an annual
PSD Report to the California Energy Commission (CEC) by June 1st of each year. The
information contained in the PSD Report is subsequently used to prepare the annual
Power Content Label (PCL) using a PCL template provided to all utilities each year by
the CEC. The PCL is made available to our customers around September of each year,
and is posted on the District's and the CEC's website.
In 2017, the CEC regulation implementing SB 1305 was updated with important
changes that directly affected all electric utilities. The changes included a provision that
requires utilities to engage a third-party certified public accountant (CPA) to perform an
audit to verify the specific purchases and self-consumption of energy by fuel type. The
regulation includes an exemption from the audit requirement for publicly owned electric
utilities (POUs), if the governing board of the POU approves the submission and
veracity of the reports sent to the CEC.
ANALYSIS AND BODY:
District staff has compiled the data for the 2023 PSD based on the information provided
and verified by our electric suppliers, including Utah Associated Municipal Power
Systems (UAMPS), Western Area Power Administration (WAPA) and Western
Electricity Coordinating Council (WECC). In addition, the District contracts with a third-
party verifier to prepare a report for all electricity transactions, and submits this report

Page 46 of 153
annually to California Air Resources Board (CARB) in compliance with State regulations
and CARB Greenhouse Gas Emissions reporting requirements. Staff have further
reviewed this information and are confident in the accuracy of the information being
reported.
The proposed Resolution 2024-20 approves the 2023 PSD Report and PCL submission
and provides an attestation on the veracity of the reports, as required by the CEC for
exemption from the third-party CPA audit requirement. The 2023 PSD Report and PCL
are included as Exhibits A and B respectively, in Resolution 2024-20.
The 2023 PCL (Attachment 1, Exhibit B) lists the total eligible renewable percentage of
47.3%, and the total percentage of retail sales covered by retired unbundled renewable
energy credits (RECs) as 12.8%. The District has a diverse portfolio of renewable
resources, including hydroelectric, landfill gas, wind, and heat recovery generation.
Most of these resources include the REC attributes transferred to the District in
accordance with the energy generated, and are included in the total renewable energy
percentage of 47.3%. However, several resources, including Stampede Hydroelectric,
TCID Hydroelectric, and Veyo Heat Recovery Projects, come with a partial amount of
RECs, or no RECs at all. Since these are RPS eligible and/or carbon free resources,
the District purchases unbundled RECs to supply the REC attribute lacking from these
resources, representing 12.8% of retail sales as shown in the PCL. Therefore, the
District's RPS achievement for 2023 is the sum of these two numbers, or 60.1% RPS.
The District's RPS achievement of 60.1% for 2023 is about 1% higher than the 2022
RPS value of 59.9%. The primary factors contributing to a higher value RPS value this
year are the addition of Red Mesa solar, which came online in March 2023, and a 1%
decrease in energy sales.
GOALS AND OBJECTIVES:
District Code 1 .05.020 Objectives:
1. Responsibly serve the public.
5. Manage the District in an environmentally sound manner.
District Code 1 .05.030 Goals:
1. Manage for Financial Stability and Resiliency
2. Environmental Stewardship: Create a sustainable resilient environment for all our
communities.
FISCAL IMPACT:
There is no fiscal impact associated with approving the submission and attesting to the
veracity of the 2023 Power Source Disclosure Report and Power Content Label.

The eligible renewable percentage above does not reflect RPS compliance, which is determined
using a different methodology.
Unspecified power is electricity that has been purchased through open market transactions and is
not traceable to a specific generation source.
3Renewable energy credits (RECs)are tracking instruments issued for renewable generation.
Unbundled renewable energy credits (RECs) represent renewable generation that was not
delivered to serve retail sales. Unbundled RECs are not reflected in the power mix or GHG
emissions intensities above.
