Energy Storage:

In 2010, the California Legislature authorized the CPUC to evaluate energy storage procurement targets for load serving entities (AB 2514). In 2013, the CPUC issued Decision 13-10-040 setting the nation’s first energy storage procurement target of 1,325 MW by 2020, divided among PG&E, SCE, and SDG&E. AB 2868 (2016) required the three IOUs to propose programs to accelerate deployment of an additional 500 MW of distributed energy storage. California’s three IOUs have collectively exceeded the AB 2514 target.

In August 2024, the CPUC authorized centralized procurement of up to 2 GW of long duration energy storage (1 GW at 12+ hour duration and 1 GW multi day) deployable between 2031 and 2037 (D.24-08-064). The Self-Generation Incentive Program (SGIP) continues to fund customer-sited energy storage.
