Groundbreaking flow battery project helping to advance clean energy microgrids

SAN DIEGO – Two years after becoming the first battery of its kind to be connected to the California grid to help support reliability and maximize the use of clean energy, the vanadium redox flow battery based at a San Diego Gas & Electric substation is again breaking new ground. This time, the emerging battery technology is being tested as a means to help achieve zero-emission microgrids – a tool to keep communities and critical facilities powered with clean energy during adverse weather conditions and Public Safety Power Shutoffs.
