esVolta, a developer and owner of utility-scale energy storage projects across North America, has been selected to deliver a new Li-ion battery energy storage system for California Choice Energy Authority (CalChoice), a hybrid joint powers authority made up of five operational community choice aggregations (CCAs) in the cities of Lancaster, Pico Rivera, Rancho Mirage, San Jacinto, and the Town of Apple Valley, California.

Under the new contract, esVolta will develop, build, and operate the Black Walnut Energy Storage project, a 15 MW / 60 MWh facility to be built in Santa Paula, California. The project is slated to be in service by June 2022.

The Black Walnut project was selected by CalChoice to provide incremental resource adequacy to help ensure sufficient capacity to meet anticipated load growth for each member CCA. The project will also provide an array of energy and ancillary services to the electric grid.

esVolta currently has approximately 575 MWh of energy storage projects in operation, under construction, or under development pursuant to executed utility and CCA off-take contracts, in addition to a pipeline of approximately 2,000 MWh of additional development stage projects.
