New facility, built in partnership with AES Energy Storage, will enhance regional energy reliability while maximizing renewable energy use
SAN DIEGO, Feb. 24, 2017 /PRNewswire/ -- Today, SDG&E is showcasing the world's largest lithium-ion battery energy storage facility in partnership with AES Energy Storage, 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.
Last year, the California Public Utility Commission (CPUC) directed Southern California investor-owned electric utilities to fast-track additional energy storage options to enhance regional energy reliability. In response, SDG&E expedited ongoing negotiations and contracted with AES Energy Storage to build two projects for a total of 37.5 MW of lithium ion battery energy storage. In addition to the 30 MW facility built in Escondido, Calif., a smaller 7.5 MW installation was built in El Cajon.
"San Diego County is a community of leadership and innovation, so it is only fitting that this community should receive the benefit of this unique project," said Scott Drury, SDG&E's president. "For more than a decade, SDG&E has been at the forefront to deliver results consistent with state and local clean energy and carbon emission goals. These projects affirm our commitment to deliver clean energy to customers and to provide a more reliable power supply to our electric grid when it is most needed."
The 400,000 batteries, similar to those in electric vehicles, were installed in nearly 20,000 modules and placed in 24 containers. The batteries will act like a sponge, soaking up and storing energy when it is abundant - when the sun is shining, the wind is blowing and energy use is low - and releasing it when energy resources are in high demand. This will provide reliable energy when customers need it most, and maximize the use of renewable resources such as solar and wind.
"SDG&E is a leader in providing clean, reliable power to their customers, and we're honored that they chose Advancion energy storage to serve their needs," said John Zahurancik, AES Energy Storage president. "These two projects, including the world's largest advanced energy storage site, are the latest proof of energy storage's capacity to scale up and solve our most pressing grid issues in a short period."
Energy storage is playing a key role in SDG&E's commitment to delivering clean, safe and reliable energy. By 2030, the company expects to develop or interconnect more than 330 MWs of energy storage on the system. These projects can help support the delivery of more renewables to customers and help strengthen SDG&E's record as the most reliable utility in the West.
SDG&E is an innovative San Diego-based energy company that provides safe, reliable, clean energy to better the lives of the people it serves in San Diego and southern Orange counties. More than 4,100 employees work to provide the cleanest and most reliable energy in the West. The company has been recognized by the U.S. Environmental Protection Agency for leadership in addressing climate change, was the first to meet California's goal of delivering 33 percent of energy from renewable sources, has fueled the adoption of electric vehicles and energy efficiency through unique customer programs, and supports more than 600 non-profit partners. SDG&E is a subsidiary of Sempra Energy (NYSE: SRE), a Fortune 500 energy services holding company based in San Diego.
