California gas plant to be re-powered with batteries + solar

For the second time in a month a fossil fuel-fired power plant in California is set to be replaced by a battery powered by a solar, including distributed solar. A small portion of the former plant will be retained. While it has been no secret that the City of Glendale, California has been looking to re-power the aging gas-fired Grayson Power Plant with renewables, details the scope of that project, as well as the carveouts for each specific type of generation proved to be scarce. That all has changed, however, as the city has released a plan to replace all but one of the plant’s existing generation facilities with a mix of battery storage, distributed solar and geothermal energy. Broken down by capacity, the plan calls for a 75 MW, 300 MWh battery energy storage system, up to 50 MW of distributed solar projects, energy efficiency and demand response programs. The plan also calls to keep the “peaker” portion of the former plant, which totals 93 MW of gas generation from up to five combustion turbines.
