Southern California Edison Company (SCE) has selected esVolta, a developer and owner of utility-scale energy storage projects across North America, to deliver a series of lithium-ion battery energy storage systems in Riverside and Ventura Counties.
Under the contracts, which are pending approval by the California Public Utilities Commission (CPUC), esVolta will develop, build, and operate the Wildcat Energy Storage project (a 3 MW / 12 MWh facility) near Palm Springs, California and the three Acorn Energy Storage projects (total combined storage capacity of 6.5 MW / 26.5 MWh) in Thousand Oaks, California. All four projects are slated to be in service by March 2020.
The Wildcat and Acorn projects were selected by SCE through its 2017 Integrated Distributed Energy Resources RFO and are designed to provide incremental capacity at specifically targeted locations along SCE’s electric distribution system, thereby enhancing reliability and avoiding more costly distribution system upgrades that otherwise would be necessary to meet anticipated load growth. . . .
These projects are part of California's requirement that IOU's invest in energy storage:
