Southern California Edison signs contracts for another 590MW of battery storage

Greentech Media:

Six months after inking California’s largest single energy storage procurement, utility Southern California Edison has added another three massive utility-scale battery projects to its portfolio—plus a behind-the-meter battery project with Sunrun.

Monday’s new contracts include 585 megawatts of lithium-ion batteries: NextEra Energy’s 325-MW Desert Peak project, Recurrent Energy’s 200-MW Crimson project, and 174 Power Global / Hanwha Group’s 60-MW Eldorado Valley project. It also adds a 5-MW behind-the-meter battery aggregation from Sunrun, expanding on a pilot project with the solar-storage provider earlier this year to add a full-scale deployment for delivery in 2023.

The four-hour duration 2.63 gigawatt-hours [adds] to an SCE battery portfolio that’s already topping the U.S. utility record books. In May, SCE announced contracts for 770 megawatts of large-scale battery contracts with vendors including NextEra, TerraGen Power, LS Power and Southern Power, equating to more than 3 gigawatt-hours of storage capacity set to come online by August 2021.

The new contracts bring SCE’s energy storage total to just more than 2 GW installed and procured to date. If approved by the California Public Utilities Commission, the NextEra contract is set for delivery in 2023, while the other two utility-scale projects are scheduled to come online in 2022.

The new projects will help meet both short- and long-term goals for California’s only electric-only investor-owned utility. In the short term, the new procurement meets last year’s California Public Utilities Commission order to deliver a combined 3.3 gigawatts of resources by 2023 to help the state manage grid reliability.

SCE has taken the lead in securing battery storage to meet those targets, but others are following suit. Pacific Gas & Electric is contracting seven battery projects totaling 423 megawatts, or nearly 1.7 gigawatt-hours of energy storage capacity, for August 2021 delivery. Municipal utility Los Angeles Department of Water and Power has contracted for up to 300 megawatts/1.2 gigawatt-hours of storage being built alongside 400 megawatts of solar power being built by 8Minute Energy.
