Cpuc energy storage proceedings

How will the CPUC's directive impact California's energy supply strategy?

By 2037, the CPUC’s directive could lead to the completion of this procurement strategy, if bid costs are found to be reasonable and contracts are approved, enhancing California’s grid storage by up to 2 GW and increasing energy production by up to 8.6 GW.

Does energy storage meet local and system capacity requirements?

R. 13-12-010: This rulemaking determined that energy storage can meet local and system capacity requirements R. 14-08-013: This rulemaking determined that energy Storage may be included as a distribution upgrade deferral asset. R.14-10-010: This rulemaking determined that energy storage's ramping attributes can provide flexible capacity.

How does the CPUC use the solve capacity expansion model?

The CPUC uses the RESOLVE capacity expansion model as a core analytical tool to develop a Reference System Portfolio.

What does the CPUC do?

The CPUC regulates services and utilities, protects consumers, safeguards the environment, and assures Californians access to safe and reliable utility infrastructure and services. Visit www.cpuc.ca.gov for more information. News Release

Do battery storage resources provide marginal ELCC?

This study evaluates the marginal ELCC provided by battery storage resources in the context of the future 2022 and 2030 CAISO systems with significant penetrations of solar resources—a total of nearly 50 GW in 2030, including both utility-scale and behind- the-meter resources.

Do energy storage resources provide ancillary services without discharging energy?

Since assumptions used in SERVM simulations by the CPUC include operating reserves of 4.5% of hourly gross load to be protected even during firm load shed events, a commensurate quantity of energy storage resources are able to serve ancillary services and provide full reliability during emergency events without discharging energy.
