Long-Duration Energy Storage

Long-duration energy storage projects are fast-starting, quick-ramping, high-capacity resources that can help balance peak loads and enhance clean-energy resources’ ability to meet the needs of the electric grid. Strategic bulk-storage investments will allow us to park surplus renewable energy for times of low supply, and provide flexibility to the grid without burning fossil fuels. CEERT vigorously advocates for long-duration energy storage at the CAISO and in CPUC procurement rulemakings.

Recent Developments:

CEERT monitored the recent CEC workshop on Long Duration Energy Storage Technologies, and is working with the CEC staff and other stakeholders on the implementation of the Governor’s proposal for $350 million over the next two years for long-duration energy storage demonstration projects, and on the implementation of SB 423 (Stern), which requires the CEC to do an assessment of zero-carbon firm energy resources, including LDES, geothermal, and offshore wind.
