SDG&E signs five contracts for 83.5 MW local battery storage facility

San Diego Gas & Electric (SDG&E) announced that it has submitted six projects to the California Public Utilities Commission, five for 83.5 Mw new local battery storage facility and one to add 4.5 MW response program.

After approval, two of the five lithium-ion battery energy storage facilities will be owned and operated by SDG&E to enhance regional energy reliability while maximizing renewable energy use. AES Energy Storage will construct a 40-MW storage facility, building on its successful 37.5 MWs of deployments in Escondido and El Cajon. A 30-MW facility will be built in Miramar by Renewable Energy Systems Americas Inc. (RES). The other storage projects totaling 13.5 MW will be owned by third parties including Powin Energy, Enel through its U.S. subsidiary Enel Green Power North America, and Advanced Microgrid Solutions and constructed in Escondido, Poway and San Juan Capistrano.

All the battery projects can store supplies of solar, wind and other traditional sources and release it when energy is in high demand.

SDG&E’s VP of energy procurement, Emily Shults said that these projects will add more flexibility to the system and help us to ensure reliability while providing greater levels of clean energy to all of their local communities. By building these projects, SDG&E will remain at the forefront of helping the state achieve its bold clean-energy and carbon-emission targets.
