For California to achieve its target of eliminating greenhouse gas (GHG) emissions from its electricity sector by 2045, the state will need to deploy between 45GW and 55GW of long-duration energy storage, a new study has found.

Another contract has been signed for energy from a large-scale solar-plus-storage plant by one of California’s Community Choice Aggregator (CCA) groups.

Vertically integrated solar PV company Canadian Solar will install 75MW / 300MWh of battery energy storage at a California solar power plant owned by Goldman Sachs Renewable Power.

A group of Community Choice Aggregators (CCAs) in California, US, are seeking long-duration energy storage to add resiliency to their electricity networks serving around three million customers.

While redesigning California’s energy system will take some time, in the past couple of weeks alone, Energy-Storage.news has become aware of numerous initiatives and projects, both publicly and privately-driven, that are seeking to modernise, add resilience to and lower the emissions of the California grid.

Clean Power Alliance, one of California’s community choice aggregator (CCA) groups has signed a 15-year power purchase agreement (PPA) with developer 8minute Solar Energy for the output of a massive solar-plus-storage plant.

Goldman Sachs Renewable Power has acquired a 100MW solar PV plant with a 50MW battery storage facility currently under development in San Bernadino, California.

Lynn Jurich, CEO at major US residential solar installation and leasing company Sunrun has spoken of the big opportunity for aggregated solar-plus-storage systems to provide grid services and in doing so help lower the cost of installations.

California investor-owned utility (IOU) Pacific Gas & Electric has begun work constructing a 182.5MW / 730MWh battery energy storage system (BESS) project at a substation in California.
