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.

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.

Four energy storage projects that have been proposed as an alternative to expensive transmission and distribution (T&D) network upgrades, totalling 38.5MWh of capacity, have been awarded to developer EsVolta by California utility Southern California Edison (SCE).
