To replace 2150 megawatts of generation lost by the retirement of a nuclear powerplant, the California Public Utilities Commission has directed two utility companies to procure up to 1,500 MW of new resources. At least 600 MW must be from energy storage and “preferred resources,” which the state defines as renewable power, demand response sources and energy efficiency.
Southern California Edison Co. (SCE), Rosemead, must procure 500-700 MW and San Diego Gas & Electric Co. (SDG&E) 500-800 MW by 2022 to meet local capacity needs following the shutdown of the San Onofre Nuclear Generating Station (SONGS). SCE also must procure at least 50 MW and SDG&E 25 MW from energy storage.
