Net Energy Metering and Shared Renewable Energy
Annual Report to Commission for FY 2024-2025
Introduction
Hetch Hetchy Power’s Net Energy Metering (NEM) and Shared Renewable Energy (NEM -ShaRE) Programs and CleanPowerSF’s Net Energy Metering Program are customer program offerings from the SFPUC Power Enterprise that allow customers with on-site renewable energy systems to gain financial credits for the generation of solar electricity not consumed on site.
SFPUC Resolutions 16 -0086 and 16 -0072 direct the General Manager to report annually on the performance of these programs . Specifically, these resolutions require reporting on the total rated generating capacity enrolled in the program, the amount of net surplus electricity compensation provided to eligible customer- generators under the program, as well as potential program refinements and enhancements that may further protect non -participants from cost shifting and/or improve the ability of the SFPUC to promote the continued development of local renewable energy resources in a financially sustainable manner. Pursuant to those resolutions, th is report for Fiscal Year 2024-2025 is presented for the Commission’s review.
Hetch Hetchy Power’s Net Energy Metering and Shared Renewable Energy Programs In Fiscal Year 2024 -2025, generation from four customer-owned solar systems participating in Hetch Hetchy Power's NEM and NEM -ShaRE Programs resulted in a total of 265,664 kilowatt-hours (kWh) in NEM credits applied to the program participants’ respective energy bills. Staff are continuing to review generator interconnection and NEM applications for customers located within Hetch Hetchy Power’s service area who in the future may be interested and eligible participants for the Net Energy Metering and Shared Renewable Energy Programs.
CleanPowerSF’s Net Energy Metering Program
In Fiscal Year 2024 -2025, CleanPowerSF served 13 ,508 Net Energy Metering (NEM) customer accounts with an estimated total solar capacity of 72,621 kilowatts (direct current).1 NEM customers represented
3.51 percent of all active CleanPowerSF customers. As of May 2025, participating NEM customers generated 6,784,791 kWh in ex cess electricity. A total of $ 572,032 in net surplus compensation was provided to 3,772 eligible net generators, or about 2 7 percent of the customers receiving NEM service
1 CleanPowerSF’s estimated total solar capacity was calculated using the CleanPowerSF Interconnection Report 2025 Q2, produced by PG&E. Service point IDs and service addresses were used to link CleanPowerSF customer accounts to the associated interconnection record which includes system size. An average was added to the total capacity of known interconnections to account for the capacity of those CleanPowerSF NEM accounts that could not be associated with a specific interconnection record (approximately 13 percent).
2 from CleanPowerSF . As of October 20, 2025 , an estimated 709 NEM customers have received their requested cash out following the May 2025 True Up. The remaining 3,063 net generators who did not request a cash out will receive a “roll over” bill credit for their net surplus compensation.
Per our 2023-2024 Net Energy Metering and Shared Renewable Energy Report2, CleanPowerSF has been accommodating customers on PG&E’s Solar Billing Plan on CleanPowerSF’s Net Energy Metering tariff pending the development of a CleanPowerSF Solar Billing Plan proposal. We have completed our analysis and will be presenting a CleanPowerSF Solar Billing Plan proposal at a Commission Meeting early next year.
Should the proposal be adopted, CleanPowerSF rooftop solar customers will be served under two tariffs:
Net Energy Metering and the Solar Billing Plan. CleanPowerSF’s proposed S olar Billing Plan tariff will be limited to customers on PG&E’s Solar Billing Plan, which includes customers with solar connections approved after April 2023, or with systems more than 20 years old. Other pre-existing NEM customers will continue to be served on CleanPowerSF’s NEM program until they transition to PG&E’s Solar Billing Plan.
