Approve Execution of an Attestation of Veracity for Hetch Hetchy Power’s 2024 Power Source Disclosure Report and its Submission to the California Energy Commission
Summary of Proposed
Commission Action:
Approve execution and submission of an attestation of veracity for Hetch Hetchy Power’ s 2024 Power Source Disclosure Report and approve final submission of the 2024 Power Source Disclosure Report to the California Energy Commission.
Background: Under Public Utilities Code Sections 398.4 and 398.5 , retail suppliers of electricity must annually: (1) report to the California Energy Commission the type of generation resources ( e.g., hydroelectric, solar, wind) used to serve their end use customers in the form of the Power Source Disclosure Report; and (2) provide this same information, in the form of a Power Content Label, to their customers.
The Power Source Disclosure Report generates the Power Content Label, which provides customers with detailed information about the energy sources used by Hetch Hetchy Power and the greenhouse gas (GHG) emissions associated with that energy. This information helps consumers understand where their electricity comes from and make informed decisions about their energy consumption. Under California Energy Commission regulations, the SFPUC can attest to the veracity of the Power Source Disclosure Report for all retail products offered by Hetch Hetchy Power.
In previous years, SFPUC staff included the Power Content Label along with the Power Source Disclosure Report in this action.
However, starting this year, the California Energy Commission staff will instead generate 2024 Power Content Labels on behalf of retail suppliers, including Hetch Hetchy Power, in order to streamline the Power Content Label reporting process. The California Energy Commission aims to provide the 2024 Power Content Labels to Hetch Hetchy Power by mid -September 2025 for posting to our website by October 1, 2025. Hetch Hetchy Power is also required to provide Power Content Labels to our customers by December 31, Agenda Title: Approve Execution of an Attestation of Veracity for Hetch Hetchy Power’s 2024 Power Source Disclosure Report and its Submission to the California Energy Commission Commission Meeting Date: September 23, 2025
2025.
Hetch Hetchy Power offers two products which require this reporting: Hetch Hetchy Power and Hetch Hetchy Power Premium.
The 2024 Power Source Disclosure Report demonstrates that in 2024, Hetch Hetchy Power provided its customers with an energy product that was 100% greenhouse gas -free, sourced almost entirely from the Hetch Hetchy hydroelectric system. Hetch Hetchy Power Premium provided its customers with an energy product that was also 100% greenhouse gas -free, while also meeting California’s Renewable Portfolio Standard
1 requirements. Hetch Hetchy Power
and Hetch Hetchy Power Premium both have a greenhouse gas emissions intensity of 0 pounds of carbon dioxide equivalent (CO2e) per megawatt-hour (MWh) of generation.
As shown in the attached Power Source Disclosure Report for calendar year 2024, Hetch Hetchy Power provided its default service customers with 100% greenhouse gas -free hydroelectric energy.
Ninety-nine percent of this energy was generated by the Hetch Hetchy system and the remaining one percent from hydroelectric facilities of the Western Area Power Administration which is the source of the electric energy Hetch Hetchy Power provides to Treasure Island.2 Hetch Hetchy Power also generated a small amount of surplus energy above its retail needs from its Kirkwood generating units, solar facilities, and the Southeast Cogeneration power plant.
This energy, all of which meets California’s Renewable Portfolio Standard eligibility standards, was re-sold with Hetch Hetchy Power keeping the associated renewable energy credits . These credits can be used for Hetch Hetchy Power to meet its future Renewable Portfolio Standard compliance obligations as needed.
In calendar year 2024, Hetch Hetchy Power Premium provided its customers with 100% greenhouse gas -free hydroelectric energy which is also Renewable Portfolio Standard- eligible. Premium Service provides customers an electricity portfolio that meets the requirements of the California Air Resources Board’s Low Carbon Fuel Standard program . This allow s the San Francisco Municipal Transportation Agency, the San Francisco International Airport, and the Port of San Francisco to receive additional credits under the program which rewards entities using clean energy rather than fossil fuels for transportation-related uses.
After retail sellers submit their Power Source Disclosure Report s to the California Energy Commission, the agency then compiles them
1 Renewable Portfolio Standard-eligible renewable resources include wind, solar, biomass and biowaste, small hydroelectric and geothermal facilities.
2 A small proportion of this Western Area Power Administration power (346 MWh) also met the definition of Renewable Portfolio Standard-eligible energy.
Agenda Title: Approve Execution of an Attestation of Veracity for Hetch Hetchy Power’s 2024 Power Source Disclosure Report and its Submission to the California Energy Commission Commission Meeting Date: September 23, 2025
to determine the statewide mix of electricity resources used to meet California’s e lectricity demand. Whereas in previous years the California Energy Commission would then provide retail sellers with this information in a template for those sellers to complete their Power Content Labels, starting in 2025, the California Energy Commission will generate Power Content Labels and provide them to retail sellers, using the data contained in their Power Source Disclosure reports.
Hetch Hetchy Power will disclose the electricity sources of its sales to customers for 2024 using the Power Content Label , a draft of which is attached to this agenda item.
3 The Power Content Label
shows, in tabular form, the electricity sources for Hetch Hetchy Power’s sales and provides additional descriptive information to improve readability and understanding for customers.
As a result of A ssembly Bill 1110 (Ting, 2015 ),
4 since 2020, the
Power Source Disclosure Report also calculates greenhouse gas emissions intensity ( pounds CO2e /MWh) for each of the reporting retail seller ’s electricity products included on the Power Content Label.
Both Hetch Hetchy Power and Hetch Hetchy Power Premium had a 2024 greenhouse gas emissions intensity of 0 pounds CO2e/MWh.
To put this in context, in 2023, the latest year for which this data is currently available, California’s statewide emissions intensity was 373 pounds CO2e/MWh, and that of PG&E’s default product was 12 pounds CO2e/MWh.
Under California Energy Commission regulations, Hetch Hetchy Power must post its Power Content Label on our website by October 1, 2025 and provide all customers with a copy of the same either as a physical mailer or an electronic message (only for those customers billed electronically) by December 31, 2025.
In addition, under California Energy Commission regulations, Hetch Hetchy Power must either have its governing body (this
Commission) attest to the veracity of its Power Source Disclosure Report or have it verified by a qualified third party. The Commission has attested to the veracity of Hetch Hetchy Power’s Power Source Disclosure Report since Hetch Hetchy started its reporting in 2011.
3 The Power Content Label will be finalized after Commission action on this item and will be distributed to customers by December 31, 2025.
4 This bill amended Section 398.1 and 398.4 of the Public Utilities Code, and tasked the California Energy Commission to adopt guidelines for the reporting and disclosure of greenhouse gas emissions intensity associated with retail electricity sales.
Agenda Title: Approve Execution of an Attestation of Veracity for Hetch Hetchy Power’s 2024 Power Source Disclosure Report and its Submission to the California Energy Commission Commission Meeting Date: September 23, 2025
The attached resolution attests to the veracity of the Power Source Disclosure Report and approves its Submission to the California Energy Commission. The attestation of veracity is to be executed by the Assistant General Manager for Power or their designee, who supervised the preparation of the Power Source Disclosure Report.
Result of Inaction: If the Commission does not approve submission of an attestation of veracity, the SFPUC will be required to incur the time and cost of having the Power Source Disclosure Report independently verified and may incur fines if the verification is not completed by the California Energy Commission’s October 1st deadline.
Recommendation: SFPUC staff recommends that the Commission adopt the attached resolution.
