Additional information

SCE ’s 5 MW lithium-ion system from developer Western Grid comes with only a three-year contract term, mainly because its future energy capacity has already been spoken for, via a contract award last year to help SCE meet requirements set under California’s broader energy storage mandate, which requires the state’s big three utilities to procure 1.3 GW of energy storage by decade’s end.
