Southern California Edison unveiled North America’s biggest battery storage demonstration last week, using an 8-MW, 32-MWh lithium-ion system supplied by LG Chem. The system consists of 604 battery racks, 10,872 battery modules, and 608,832 individual battery cells, and is housed in a 6,300-square-foot building in California’s Tehachapi Mountains. “While the grid-scale energy storage industry aspires to enter commercialization, utilities might still be rooted in the demonstration stage,” Wesoff writes. But “this installation will allow us to take a serious look at the technological capabilities of energy storage on the electric grid,” according to the U.S. Department of Energy’s Energy Storage Program Manager, Imre Gyuk. “It will also help us to gain a better understanding of the value and benefit of battery energy storage.”
