The big battery project is planned for the Little Rainbow Valley, south of Buckeye, and the battery system there will be many times larger than anything in Arizona today.Utilities are adding batteries to the power grid so that they can charge with abundant solar energy in the day, and discharge that power at night, when customers use a lot of electricity but solar plants don’t create any. SRP said last year it would reduce its reliance on natural-gas-burning power plants and save money by adding solar and batteries to its system.At the time, SRP only had about 200 megawatts of solar, but now the electric utility has lined up projects that get it about 60% of the way toward that 1,000-megawatt goal.The 250-megawatt project will be called Sonoran Energy Center. It will include batteries capable of storing 250 megawatts of energy for four hours, or 1,000 megawatt-hours of electricity storage.The U.S. Energy Information Administration reported that as of March 2019, the two biggest operating battery projects in the country are the 40-megawatt Golden Valley Electric Association’s system in Alaska and the Vista Energy system in California.Batteries give electric companies flexibility in how they deliver the power. For example, the Sonoran Energy Center also could provide 125 megawatts of power for eight hours.More: SRP plans to install Arizona’s biggest battery for massive solar plantlast_img
