At the former coal power site in Boxberg, Saxony, energy company LEAG is preparing to build one of Germany’s largest battery storage facilities. The project, called GigaBattery Boxberg 400, will cover roughly six hectares, an area where cooling towers once stood before their demolition last year. The storage system is designed to deliver 400 megawatts of power and hold up to 1,600 megawatt-hours of electricity, enough to supply around 640,000 households for a few hours.
