Highlights
- In addition to rated capacity, DERs using electrochemical storage (i.e., batteries), mechanical storage, or thermal storage technologies also have energy storage capacities. In 2022, California added 80.8 megawatt-hours (MWh) of energy storage capacity across all DER sectors, with the residential sector adding almost 98 percent of the SGIP-eligible energy storage capacity. The SGIP-eligible storage capacity added in 2022 is the smallest since 2017, and represents a 65.8 percent decrease over 2021’s capacity added (236.0 MWh added in 2021). However, utility-scale storage has been increasing capacity in 2022.
- The SGIP residential unitary Heat Pump Water Heater (HPWH) Program will provide $84.7 million to equity-focused residential and commercial HPWH installations, though it is still in the proposal phase.139
