Pacific Gas & Electric Company (“PG&E”) reached its cap of 2,409 MW for the original net energy metering (“NEM”) tariff on December 15, 2016. (PG&E Advice Letter 4999-E, Jan. 17, 2017.) Upon reaching the cap, PG&E began implementation of the NEM successor tariff for customer-sited renewable distributed generation.
The NEM tariff overlies an applicable electric service rate schedule and allows customer-generators to offset their charges for consumption with the electricity provided by their on-site system. Customer-generators receive a credit for the power generated by their system that is fed back to the grid, and this credit is the per kWh price that customers would have otherwise been charged for electricity consumed. In Decision 16-01-044, the California Public Utilities Commission (“CPUC”) kept this basic NEM structure, but added new charges and rules for the successor NEM tariff. These include, in part, the following:
Customer-generators may continue to take service on the NEM successor tariff for 20 years from the year of interconnection. The CPUC plans to review the NEM program again in 2019, which is the target year for the initiation of default TOU rates for residential customers. At that time, the CPUC plans to consider adjustments to the successor tariff that include a compensation rate that takes into account locational and time-differentiated values.
