Net Billing Tariff
Updated: April 5, 2024

In late 2022, the California Public Utilities Commission (CPUC) adopted the Net Billing Tariff (NBT), also commonly referred to as NEM3. NBT is a new program for determining customer compensation for excess electricity generation exported to the grid by rooftop solar systems. It is replacing PG&E’s current Net Energy Metering (NEM) program, known as NEM2, and will apply to future customer rooftop solar installations. PG&E’s NBT program is known as Solar Billing Plan (SBP).

Existing NEM customers will remain on their current NEM tariff for 20 years from when their system was connected to the electric grid. After the 20-year period, customers will be enrolled in Net Billing Tariff (or subsequent versions of NBT).

The current Net Energy Metering tariff (NEM2) closed to new customers on April 14, 2023. Customers who submitted an interconnection application before that date must have their systems fully installed and inspected by April 15, 2026. Customers who apply to interconnect their systems after the April 14th deadline will be enrolled in PG&E’s Net Billing Tariff program.

Most residential customers will be billed under Net Billing Tariff beginning April 15, 2024 and non-residential customers will be billed in June 2024. Customers who apply to interconnect their systems after April 14, 2023 will receive temporary service under NEM2 until that time.

CleanPowerSF will be accommodating customers on PG&E’s Solar Billing Plan under CleanPowerSF’s NEM tariff for the near term. Existing NEM customers that transition to PG&E’s SBP will remain CleanPowerSF NEM customers and will see no change on the CleanPowerSF side (generation side) of the bill. Customers with new renewable facilities who are placed on PG&E’s SBP tariff will be placed on CleanPowerSF’s NEM tariff.

CleanPowerSF is in the very early stages of considering a successor tariff to CleanPowerSF’s NEM program. In 2024, CleanPowerSF plans to conduct an analysis to determine potential options for a NEM successor tariff for CleanPowerSF rooftop solar customers. We also plan to conduct community engagement to solicit public input and feedback on the development of a NEM successor tariff. Until a NEM successor tariff is adopted by the SFPUC Commission, CleanPowerSF’s current NEM tariff remains in effect.
