In partnership with AES Energy Storage, SDG&E is building the world’s largest lithium-ion battery energy storage facility which will enhance regional energy reliability while maximizing renewable energy use. The 30 megawatt (MW) energy storage facility is capable of storing up to 120 megawatt hours of energy, the energy equivalent of serving 20,000 customers for four hours. The 400,000 batteries, similar to those in electric vehicles, were installed in nearly 20,000 modules and placed in 24 containers. The project scope included relay logic functional testing, automation, and protection testing and comissioning.
