SCE Adds an Additional 590 Megawatts of New Energy Storage Capacity to Its Clean Energy Portfolio
Southern California Edison has announced the signing of long-term contracts for four projects totaling 590 megawatts of battery energy storage, enhancing regional electric system reliability. This addition, alongside a previous procurement of 770 megawatts, raises the company's total battery capacity to approximately 2,050 megawatts. The projects aim to support California's transition to 100% clean renewable energy and are expected to come online by August 2022 and 2023. Approval from the California Public Utilities Commission is required before implementation.
- Increases battery storage capacity to approximately 2,050 MW.
- Supports California's goals for clean energy and carbon neutrality.
- Creates skilled clean energy jobs and improves the economy.
- Contracts require approval from the California Public Utilities Commission, which could delay implementation.
ROSEMEAD, Calif.--(BUSINESS WIRE)--To further enhance the region’s electric system reliability needs, Southern California Edison has signed long-term contracts for four projects totaling 590 megawatts of battery energy storage resources. The recently conducted solicitation and resulting contracts are in addition to the company’s May acquisition of 770 MWs of energy storage procurement, one of the country’s largest. These contracts increase SCE’s total amount of installed and procured battery storage capacity to approximately 2,050 MWs.
“Bringing more utility-scale battery storage resources online will improve the reliability of the grid and further the integration of renewable generation resources, like wind and solar, into the grid,” said William Walsh, SCE vice president of Energy Procurement & Management. “As California transitions to
Three of the four projects are utility-scale projects totaling 585 MW and will take advantage of lithium-ion batteries that can store energy for use later.
The fourth project is a 5 MW demand response contract that will use energy from customer-owned energy storage. Economically impacted communities that suffer most from the effects of air pollution will provide
One of the many ways these flexible energy resources can be used is by capturing solar energy during the day and distributing the energy as the sun sets and energy use remains high. They can also be used to respond to the California Independent System Operator signals, high-demand events, heat waves or when the energy grid is strained.
The projects are expected to come online by August 2022 and 2023.

The procurement was part of a robust competitive process initiated by SCE last year.
As laid out in Pathway 2045, SCE estimates the state needs to add 30 GW of utility-scale storage to the grid and 10 GW of storage from distributed energy resources to meet the state’s clean energy and carbon neutrality goals. These new contracts will further help California meet these goals while providing additional grid reliability. They also help improve California’s economy by creating craft and skilled clean energy jobs while reducing GHG emissions.
The contracts will require California Public Utilities Commission approval and SCE expects to submit them for approval before the end of the year.
