...In addition to changing and upgrading some equipment at one of the pumped hydro plants, Engie’s German arm constructed a 12.5MW battery storage system at the site. Nearly 40,000 (39,600) batteries are housed in 180 racks, with each battery of about 67kWh capacity. Three 20kV transformers feed power into the local grid, maintained and operated by network operator Bayernwerke AG.
The lithium storage facility including battery management system was supplied by engineering multinational Siemens, built on the company’s Siestorage containerised battery energy storage platform.
The battery will provide primary balancing services, helping to mitigate fluctuations in frequency within 30 seconds of receiving a signal from the grid, aiding the integration of variable renewable energy sources....
