Subject: CleanPowerSF Third Quarter Update, 2026
This memorandum serves as the regular quarterly update to the San Francisco Public Utilities Commission (SFPUC or Commission) on the Power Enterprise’s CleanPowerSF program.
The third quarter of calendar year 2026 update focuses on the following topics:
1. Program Service Statistics and Enrollment Activities
2. Communications Activities
3. Customer Programs Update
4. Energy Procurement and Planning Activities
1. Program Service Statistics and Enrollment Activities CleanPowerSF continues to provide clean electricity generation services to San Francisco customers, serving about 390 ,000 active customer accounts as of August 2026. CleanPowerSF’s opt-out rate remains stable at approximately
4.85 percent of all enrolled accounts.
Figure 1: CleanPowerSF Enrollment, August 2026
Customer enrollment in SuperGreen, CleanPowerSF’s optional 100 percent renewable energy product, is currently at about 1.95 percent of active accounts, down slightly from 1.97 percent since the previous quarterly report.
In total, renewable energy sales to SuperGreen customers accounted for 18.9 percent of CleanPowerSF’s energy sales in calendar year 2025.
Enrollment in the Sup erGreen Saver program is currently fully subscribed at 1,406 accounts.
2. 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 Climate & Clean Energy Video and Writing Contest Celebration
In May, CleanPowerSF celebrated students that participated in CleanPowerSF’s first -ever Climate and Clean Energy Video and Writing Contest. This contest encouraged high-school students in San Francisco public schools to create a video, poem, or persuasive speech that showed what
“Powering San Francisco’s Future” meant to them or their community.
CleanPowerSF awarded 79 scholarships to students through the Kindergarten to College (K2C) program. Awardees were selected by a committee of SFPUC judges and received a $500 scholarship in their K2C accounts. View all the student submissions in the Contest Awardee Gallery at cleanpowersf.org/2026- contest-awardee-gallery.

b) CleanPowerSF 10th Anniversary Advertising Campaign
To celebrate the 10 th anniversary of CleanPowerSF, staff launched a citywide advertising campaign to increase awareness of the program and celebrate CleanPowerSF’s decade-long impact. The advertisements, which ran from May through July, featured photos and videos of ten CleanPowerSF customers. The ads appeared on social media, bus shelters, streaming platforms, local newspapers, and more. Advertisements were featured in English, Chinese, Filipino and Vietnamese, and directed people to cleanpowersf.org/anniversary.
Campaign results will be shared with staff this month.

c) Annual Joint Rate Mailer
The Joint Rate Mailer is an annual mailing required under state law to be sent jointly by Pacific Gas and Electric Company (PG&E) and CleanPowerSF to all customers. The notice provides a rate and energy portfolio comparison between PG&E and CleanPowerSF for four customer classes:
• Residential (E-TOU-C rate);
• Small Commercial (B-1 rate);
• Medium Commercial (B-10S rate); and
• Large Commercial (B-19S rate).
The Joint Rate Mailer is intended to promote transparency and energy choice for customers. CleanPowerSF customers received the Joint Rate Mailer via email or mailed postcard before July 1, 2026. Each notice was translated into Chinese, Spanish, Filipino and Vietnamese. The Joint Rate Mailer documents are posted on the CleanPowerSF website at cleanpowersf.org/key-documents.
3. 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) Electrify Your Home (Electrification Bill Credits)
Last quarter, the Electrify Your Home program expanded by adding heat pumps, electric cooking, and electric clothes dryers to our existing water heating offering. The program provide s $50 per -month credits to customers’ bills when they electrify their appliances. The length of these bill credits depends on which upgrade(s) are taken , with up to two years of bill credits
offered for heat pump water heaters (HPWH) and heating ventilation and air conditioning (HVAC) heat pumps. In addition to the benefits of the bill credits, we also provide participants with guidance on selecting their electricity rate , which is a critical piece to maximize the financial benefits of electrification.
Since the expansion of the program, we have awarded bill credits to an additional 23 customers for a total of 78 participating customers. Among those who participated, approximately 10 percent were also enrolled in statewide utility discount programs for income -qualified customers (e.g. California Alternate Rates for Energy or Family Electric Rate Assistance Program).
In the last quarter we also expanded our coordination with San Francisco Environment’s (SFE) Climate Equity Hub program and conducted site walks with their teams to help enroll an additional 24 customers from a local affordable housing provider with bill credits for their tenants with newly electrified heat pump water heaters.

Finally, our Electrify Your Home program was recently recognized at the California Climate and Energy Collaborative Forum with the Energy Innovations and Breakthrough Award for the financial scalability of our first -of-its-kind electrification bill credits program model.

b) Electrify My Ride (E-bike Incentive)
Electrify My Ride is designed to make sustainable and affordable transportation available to residents in San Francisco, specifically CleanPowerSF customers enrolled in an energy assistance discount program on their electricity bill. The program offers customers a $1,000 instant rebate on an e -bike purchased at participating San Francisco retailers. The program incentive budget was approximately $2 million for the last fiscal year.
During the last fiscal year, 3,389 coupons were issued, and 1,992 e-bikes were purchased, representing a 59 percent redemption rate across 16 participating retailers. Survey results indicate that participants had a range of transportation needs: 51 percent identified public transportation as their primary mode of transportation, while 31 percent primarily used a car or truck . A cross all respondents, 82 percent reported that they would not have purchased an e - bike without the rebate. Participants most reported using e -bikes for work trips, errands, and social or recreational activities. Retailer feedback also indicated increased sales and business activity associated with program participation, including one retailer reporting the addition of a full-time employee.
Program Next Steps. Building on these results, fiscal year 2026 –27 will transition to a lottery -based model with multiple incentive levels, including a $1,000 rebate for customers enrolled in an energy assistance discount program, and an anticipated $400 rebate for market-rate customers.

c) All Electric Multifamily Homes
The All -Electric Multifamily Program helps owners and representatives of multifamily affordable housing understand what it would take to transition their buildings from natural gas to efficient, all -electric systems. Offered at no cost and on a first -come, first-served basis, the program provides an electrification audit, a transition plan, guidance on available incentives, and technical support.
In October 2025 , program eligibility expanded from serving Hetch Hetchy electric customers to include multifamily affordable housing customers served by CleanPowerSF.
The program team has completed electrification roadmaps for 1,190 affordable units to date and has now enrolled three CleanPowerSF-served properties. The team is in the process of completing the first electrification roadmap for a CleanPowerSF-served property and is increasing outreach efforts to fulfill an internal goal of having at least one electrification roadmap completed for every affordable housing sponsor in San Francisco.
The photos below were taken from the latest CleanPowerSF -served property visited by the team. The first photo depicts a team member looking at the mechanical equipment located in the property’s secured garage. The second photo depicts a fairly new gas -fueled high -efficiency condensing boiler that
feeds the heating system which was found to be set at suboptimal temperatures for maximizing efficiency.

d) Power Affordability and Arrearage Management Project Last year, we launched the Affordability and Arrearage Management Project to better understand and address affordability issues. The project has two main deliverables: a Best Practices and Benchmarking Report, which evaluates current programs and policies, and a Policy and Program Recommendations Plan, which identifies potential policy and program updates and outlines implementation strategies.
The project is currently concluding the benchmarking and initial research phase. So far, we have completed interviews with peer utilities, analyzed arrearage trends, and conducted customer engagement and internal staff interviews. The next phase will focus on reviewing these findings, refining recommendations for potential updates to existing policies and programs, and developing the Affordability and Arrearage Management Plan, which will be completed in the first quarter of 2027.
4. Energy Procurement and Planning Activities
e) Commercial Operations of New Renewable and Energy
Storage Resources
In July, staff celebrated the completion of the Gonzaga Ridge Wind Project with a ribbon-cutting ceremony hosted by developer Scout Clean Energy. Gonzaga Ridge, located in Merced County, is CleanPowerSF’s largest wind energy project to date. It will provide 147.5 megawatts of clean wind energy, and 50 megawatts of reliable energy storage. The project is anticipated to come online later this year.
