SDG&E Adds Three Energy Storage Facilities to Grid
San Diego Gas & Electric (SDG&E) received approval from the California Public Utilities Commission (CPUC) to build three new energy storage facilities totaling 161MW/644MWh. The additional capacity will provide California with the ability to meet high energy demand during the summer.
These new projects will be able to provide enough capacity to meet the energy needs of more than 100,000 homes for up to four hours. The new facilities will be connected to the state energy market and the California Independent System Operator (CAISO) will be able to dispatch the power to balance demand and supply on the grid statewide.
“Investing in advanced technologies like energy storage is critical to advancing our state and region’s aggressive climate goals, including getting to net zero greenhouse gas emissions, with the added benefit of making the energy grid more resilient,” SDG&E Vice President of Energy Innovation Miguel Romero said in a statement. “Project by project, step by step, we are making progress toward a cleaner, safer and more reliable energy future.”
The new facilities, which are slated to be completed in late 2022 or early 2023, stemmed from the Emergency Reliability rulemaking proceeding under which the CPUC directed utilities to contract for additional capacity to bolster the grid. The projects are the latest of a series of energy storage investments SDG&E has been making. By March, SDG&E plans to begin commercial operation of another lithium-ion battery storage facility in Kearny Mesa, which will provide 20MW/80MWh. A third lithium-ion storage facility, 40MW/160MWh, is under construction in Fallbrook. By the end of 2022, SDG&E expects to have 145MW of SDG&E-owned storage connected to the regional grid.
