Southern California Edison has selected esVolta to develop, build and operate four energy storage projects totaling 38.5 MWh in Riverside and Ventura counties, the companies reported.

The projects, which are pending approval by the California Public Utilities Commission, include the Wildcat Energy Storage project (3 MW/12 MWh) near Palm Springs and the three Acorn Energy Storage projects (total combined capacity of 6.5 MW/26.5 MWh) in Thousand Oaks.

All four projects, if approved, are expected to go into service by March 2020.

“esVolta is delighted to be selected by SCE for the Wildcat and Acorn projects,” said Randolph Mann, president of esVolta, in a statement. “These contract awards represent a major milestone for esVolta as we continue to grow our energy storage business platform. We look forward to delivering cost-effective storage solutions for SCE, a leading electric utility and a key supporter of advanced energy storage technologies.”

Rosemead-based SCE included the Wildcat and Acorn projects as part of the utility’s integrated distributed energy resources RFO (request for offers). 

The overall RFO includes multiple distributed energy resources such as renewables, energy efficiency, demand response, energy storage, substation and circuit upgrades. They are designed to provide incremental capacity at targeted points along SCE’s electric distribution system.

State regulators have tasked California’s three investor-owned utilities—SCE, Pacific Gas & Electric and San Diego Gas & Electric—to procure 1,25 MW of energy storage capacity by 2020. SCE’s share of that target is 580 MW, according to reports.

California-based esVolta has a portfolio of operational and/or contracted storage projects totaling more than 450 MWh, according to the company.
