Southern California Edison Signs Contracts for 590 MW of Battery Energy Storage
Southern California Edison has signed long-term contracts for four projects totaling 590 megawatts of battery energy storage resources. These contracts increase SCE’s total amount of installed and procured battery storage capacity to approximately 2,050 MWs. SCE hopes this will help further enhance the region’s electric system reliability needs.
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 5% of the MWs for this project.
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.
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….
