US utility Southern California Edison (SCE) has signed long-term contracts for four projects totaling 590MW of battery energy storage resources.
The four contracts expand the utility’s total amount of installed and procured battery energy storage capacity to approximately 2,050MW.
The projects are expected to come online by August 2022 and 2023.
|Company||Project Name||Size (MW)||Online Date|
|174 Power Global / Hanwha Group||Eldorado Valley||60||8/1/2022|
|NextEra Energy||Desert Peak||325||8/1/2023|
Three of the four projects are utility-scale projects totaling 585MW and will take advantage of lithium-ion batteries that can store energy for use later.
The fourth project is a 5MW 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 5% of the MWs for this project.
Southern California Edison estimates the state needs to add 30GW of utility-scale storage to the grid and 10GW of storage from distributed energy resources to meet the state’s clean energy and carbon neutrality goals.
William Walsh, SCE vice president of energy procurement & management, said: “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.
“As California transitions to 100% clean renewable energy to reduce the greenhouse gas emissions that are driving climate change, battery storage will play a key role in harnessing the value of these cost-effective, carbon-free resources in a reliable manner.”
