SAN DIEGO, March 16, 2017 /PRNewswire/ — Today, SDG&E is unveiling a new vanadium redox flow (VRF) battery storage pilot project in coordination with Sumitomo Electric (SEI), which stemmed from a partnership between Japan’s New Energy and Industrial Development Organization (NEDO) and the California Governor’s Office of Business and Economic Development (GO-Biz). During the four-year demonstration project, SDG&E will be researching if flow battery technology can economically enhance the delivery of reliable energy to customers, integrate growing amounts of renewable energy and increase the flexibility in the way the company manages the power grid.
“SDG&E is continuously at the forefront of delivering clean energy solutions and championing innovative technologies to assess the long-term benefits for our customers,” said Caroline Winn, SDG&E’s chief operating officer. “This pilot will advance our understanding of how this flow battery technology can help us increase the reliable delivery of clean energy to our customers and align with state and local carbon emission reduction goals.”
The vanadium redox flow battery storage facility will provide 2 megawatts (MW) of energy, enough to power the energy equivalent of about 1,000 homes for up to four hours. Like other battery storage systems, the battery will act like a sponge to soak up renewable energy harnessed from the sun and release it when resources are in high demand.
Flow battery systems have an expected life-span of more than 20 years, and could have less degradation over time from repeated charging cycles than other technologies. SDG&E will be testing voltage frequency, power outage support and shifting energy demand.
“We are delighted to see our first flow battery system operating in the U.S. through the multiple-use operation of the battery system in SDG&E’s distribution network, we would like to prove its economic value and potential use on the electric grids,” said Junji Itoh, managing director of Sumitomo Electric.
“California continues to lead the nation when it comes to growing the economy and decreasing emissions,” said Sid Voorakkara, Deputy Director for External Affairs at the Governor’s Office of Business and Economic Development. “GO-Biz is proud to partner with NEDO to bring this demonstration project to life and increase opportunities for economic growth powered by renewable energy.”
SDG&E has been a leader in bringing energy storage options into the region with the recent unveiling of the world’s largest lithium ion battery storage facility in Escondido and a smaller facility in El Cajon. To date, SDG&E has approximately 100 MW of energy storage projects completed or contracted.
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.
