Go With the Flow: Battery System in Bonita to be Tested for Use in Microgrids

A battery storage demonstration project already providing a carbon-free source of electricity to California’s grid is about to be tested to see how well it can work on microgrids.

Located on a bluff at a San Diego Gas & Electric substation in Bonita, the energy storage project uses vanadium redox flow battery technology that stores electricity when the grid has excess supply and then discharges the energy when the power system needs it.
