The world’s largest battery could soon be storing solar energy deep in the heart of Texas oil country.

The 495-megawatt storage system would be built in tandem with a solar farm of the same size in Borden County, Texas. The Electric Reliability Council of Texas Inc., which operates most of the state’s grid, posted the details in a chart that shows the state’s battery storage will surge more than sixfold to 584 megawatts when the projects are completed in 2021.
