Large-Scale Energy Storage
Large-scale 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 large-scale storage at the CAISO and in CPUC procurement rulemakings.
Partly as a result of CEERT’s nonpolitical advocacy in support of actions to undertake procurement of large-scale storage, Assemblymember Bill Quirk has recently amended legislation (AB 2787) to require CAISO to develop a procurement plan for 1,000-2,000 MW of large-scale storage and a methodology for allocating costs to all load-serving entities. Long-duration storage is not defined, but would presumably include pumped hydro, compressed air, solar thermal with storage, and perhaps hydrogen. The legislation is sponsored by Next Era Energy and is supported by National Grid and the California Building & Trades Council.
