SCE Announces Contracts for 770 MW of New Energy Storage Capacity
LCG, May 7, 2020--Southern California Edison (SCE) Friday announced that it has signed seven contracts for battery energy storage systems (BESS) to enhance reliability in California. The contracts, with terms ranging from 10 to 20 years, will provide in aggregate 770 MW/3,080 MWh of battery storage resources. The projects are located across Southern California’s Kern, Fresno, Riverside and San Diego counties, and all projects are scheduled to commence operations by August 1, 2021.
SCE’s vice president of Energy Procurement & Management stated, “Signing these contracts aligns with SCE’s Pathway 2045, continues our support of California’s goal to green the state and also encourages clean energy projects of all types, creating jobs and strengthening our economy.”
The seven storage projects should improve reliability in California, where reliance on intermittent renewable generation resources continues to grow to meet the States renewable and green house gas (GHG) emission goals, and aging, dispatchable natural gas plants, including coastal plants with once-through cooling, are retired. The California Public Utilities Commission (CPUC) has targeted adding approximately 8,900 MW of energy storage capacity by 2030 in the State to support reliability in the quest to achieve GHG emission reduction goals.
Most of the seven battery storage projects are co-located with solar facilities so that the solar facilities can be used to charge the battery over the term of the contract and potentially utilize the federal Investment Tax Credit (ITC). The contract capacities range in size from 50 MW to 230 MW. These projects will be located at the same point of interconnection and will be the first of their kind on California’s grid.
The selected bidders for the projects are NextEra Energy Resources (three projects, totaling 460 MW), Southern Power (two projects, totaling 160 MW), LS Power (one project, 100 MW), and TerraGen Power (one project, 50 MW). The contracts will require CPUC approval, and SCE expects to submit the contracts for approval later this month.
