Investor-owned utility (IOU) Southern California Edison (SCE) is seeking regulatory approval of resource adequacy (RA) contracts covering 620MW of BESS capacity across three projects.

Aypa Power has negotiated two resource adequacy agreements with Pacific Gas & Electric covering 500MW/2,000MWh of energy storage from two standalone BESS projects in the Californian cities of Industry and Irwindale.

The California Public Utilities Commission (CPUC) has authorised a new centralised strategy for procuring long-lead-time resources, including long-duration energy storage (LDES).

The CPUC has proposed the procurement of over 10GW of new energy resources, including 1GW of multi-day long-duration energy storage (LDES) and another 1GW of 12-hour-plus LDES.

SCE is seeking approval from the California Public Utilities Commission of two new RA agreements covering 750MW of nameplate battery storage capacity.

Attorney Seth Hilton discusses “a new dynamic for energy storage resources” around resource adequacy in California’s CAISO market.

A ‘first of its kind’ microgrid will be installed at a California substation, where it will use a combination of lithium-ion batteries and green hydrogen to provide 48 hours of back up.

CPUC approved rules of programme to offer US$200 million funding for microgrid projects in the service areas of investor-owned utilities.

NextEra’s eight-hour energy storage project in California will use lithium-ion technology, but ‘battery chemistry did not play a major role in project evaluation’, offtaker Clean Power Alliance told Energy-Storage.news.

California’s net metering successor is controversial, but residential battery storage providers Neovolta and Sonnen have greeted it warmly.
