1. Program Service Statistics and Enrollment Activities CleanPowerSF continues to provide clean electricity generation services to San Francisco customers, serving about 3 90,000 active customer accounts as of February 2026. CleanPowerSF’s opt-out rate remains stable at approximately 4.79 percent of all enrolled accounts.
Figure 1: CleanPowerSF Enrollment, February 2025
Customer enrollment in SuperGreen, CleanPowerSF’s optional 100 percent renewable energy product, is currently at about 1.99 percent of active accounts, down slightly from 2. 03 percent since the previous quarterly report.
In total, renewable energy sales to SuperGreen customers accounted for 1 8.9 percent of CleanPowerSF’s energy sales in calendar year 2025.
Enrollment in the SuperGreen Saver program is currently fully subscribed at 1,509 accounts.
2. CleanPowerSF Rate Reduction
As of March 1, CleanPowerSF customers experienced a 20 to 25% reduction in the electric generation portion of their PG&E bills. The rate cut, which was approved by the Commission on January 27, helps offset approximately 15% to 25% increases in PG&E delivery and other electricity charges billed by PG&E on the same bill as CleanPowerSF service. CleanPowerSF was able to offer this rate reduction due to its strong financial reserves and declines in power purchase expenses relative to budgeted amounts.
The March 1 rate reduction absorbing PG&E rate increases is further evidence of the value CleanPowerSF can provide to San Franciscans . Under

CleanPowerSF, customers not only enjoy predictable and stable rates as compared to PG&E but also cleaner energy, local programs and reinvestment in our community.
3. Communications Activities
CleanPowerSF is in the community, and we regularly communicate with customers and the general public about our programs and services. Below are some highlights from this past quarter.
a) CleanPowerSF Customer E-Newsletter
CleanPowerSF sent its quarterly e -newsletter to customers in January. The e- newsletter highlighted the CleanPowerSF rate decrease, the then-upcoming “Understanding the Changes Coming to Your Electric Bill” webinar, how to manage your electric bill this winter, and more. The customer e- newsletter is translated into Spanish, Cantonese, Filipino and Vietnamese. The design has also been updated to ensure it meets new accessibility requirements mandated by the federal government that go into effect on April 26, 2026.
b) “Understanding the Changes Coming to Your Electric Bill” Webinar
CleanPowerSF hosted a free, one-hour webinar for CleanPowerSF customers called “Understanding the Changes Coming to Your Electric Bill” on Thursday, February 19.
1 The webinar covered CleanPowerSF’s 20-25% rate decrease, PG&E’s new Base Services Charge, updates to a fee called the Power Charge Indifference Adjustment (PCIA), and resources for how customers can manage their bill. Over 100 people attended the webinar.

4. Customer Programs Update
CleanPowerSF continues to develop and offer programs that help customers manage their energy costs, reduce their carbon footprint, and align with City and state environmental goals. Below are some highlights from this past quarter.
a) Go Electric Bill Credits (previously Water Heater Upgrade Program)
Last year, CleanPowerSF transitioned our water heater incentives from a contractor incentive program to a new novel bill credits incentive model . The new bill credits program provides direct support to our residential ustomers in the form of on-going discounts on electric bills. The key features of the new program include:
• Monthly bill credits: Customers receive $50/month in electrification credits. Customers receive $1,200 over two years, while income- qualified customers will receive $1,800 over three years. • Electrification Rate and demand response program requirement s:
Customers are required to enroll in an electrification rate (e.g. EV2-A or E-ELEC) and a demand response program (e.g. OhmConnect or Hourly Flex Pricing). Together these requirements ensure that their equipment is operated to support a cost-effective electrification experience for the customer.
• Additional program navigation: Support connecting customers to other rebate and incentive opportunities to obtain reduced upfront costs for new electric appliances.
Last year, we opened this offering as the Water Heater Upgrade Program , providing incentives only for heat pump water heaters. T his year, we are expanding the offering to include space hea ting, clean cooking, and high efficiency clothes dryers to provide incentives to homeowners to “go electric” for all their existing gas appliances. We look forward to announcing the expanded program in April 2026.
5. Energy Procurement and Planning Activities
a) Status of Renewable Energy & Storage Solicitations
CleanPowerSF is actively soliciting renewable energy from new , to be constructed, projects. On February 6, 2026, The SFPUC released a Request for Offers to supply the SuperGreen Saver program , also known as the Disadvantaged Communities Green Tariff (PRO.0223(R)). This solicitation is for new Eligible Renewable Energy Resources that are located within five miles of an e ligible Disadvantaged Community census tract . The solicitation is necessary to support the C alifornia PUC’s requirements of program administrators, like CleanPowerSF, offering a Disadvantaged Community Page | 5
Green Tariff program. Offers submitted under PRO.0223(R) are due by April 2, 2026.2
CleanPowerSF is a member of California Community Power (CC Power), a Joint Powers Authority 3 created to perform joint procurement of clean energy resources that would benefit from greater buyer economies of scale than members might achieve on their own . CC Power recently issued a solicitation 4 to procure new clean energy and reliability resources on behalf of its members.
This solicitation closed on December 25, 2025 and CC Power, in coordination with its members, is currently finalizing a shortlist of submitted offers. Staff will share more information about this solicitation process as it becomes available. b) Execution of N ew Long -term Solar and Storage Purchase Agreements
On November 12, 2025, the SFPUC executed two new fifteen-year Renewable Energy and Energy Storage Agreements with the to-be-built Darden III and Darden IV solar and battery storage facilities (“The Darden Project”) . The agreements will support CleanPower SF’s regulatory compliance and clean energy supply objectives through the early 2040s.
Under the agreements , CleanPowerSF will purchase approximately 70 megawatts of solar energy and energy storage. The agreements will generate enough energy to supply over 58,000 average San Francisco households each year. The Darden Project will be constructed in Fresno County, California under a five- trade Project Labor Agreement. The project is expected to commence commercial operation by June 1, 2028.
c) CleanPowerSF’s Next Integrated Resource Plan
Integrated Resource Plans (IRPs) are a standard utility practice involving forecasting customer electricity demand and evaluating power supply resource options to deliver reliable and cost -effective electricity to customers, while meeting other policy goals, typically over a 20 -year planning horizon. Under state law, the California PUC requires electricity providers under its jurisdiction, including CleanPowerSF, to prepare an IRP about every two years.
CleanPowerSF’s most recent IRP was approved by the Commission on

https://sfbid.sfwater.org/opportunity-details/367/2026-disadvantaged-communities- green-tariff-(re-bid)#tab=details [ Accessed on February 18, 2026] 3 The Commission by Resolution No. 21-0023 and the Board by Ordinance No. 25-21, authorized CleanPowerSF to become a member of CC Power. In April 2021, the CC Power Board approved CleanPowerSF’s membership.

October 24, 2022 and submitted to the California PUC on November 1, 2022.56 The 2022 IRP, including modeling summaries and results, can be found at https://www.cleanpowersf.org/resourceplan.
The California PUC initiated the current IRP cycle through Rulemaking 25- 06- 019. On January 16, 2026, the California PUC issued a ruling requiring IRPs to be submitted by June 1, 2026. The detailed modeling inputs and assumptions, which are required to complete IRP modeling and analysis, were released on February 10, 2026. This provides load -serving entities with just under four months to prepare their filings.
CleanPowerSF staff have begun preparing the next IRP, including updating load forecasts and supply resource assumptions in preparation to perform the required analysis . CleanPowerSF has supported a request submitted by the California Community Choice Association and other parties to revise the IRP schedule to allow six months following the release of final modeling inputs and assumptions, consistent with prior C alifornia PUC practice. If the request is approved by the C alifornia PUC, the IRP would be due on or around August 10, 2026. CleanPowerSF staff will continue IRP development and will provide updates to the Commission and stakeholders as modeling progresses and additional California PUC guidance becomes available.
