- The battery storage system in Förderstedt, Saxony-Anhalt, will be Germany's largest with a final capacity of 300 MW and storage capacity of 716 MWh.
- The first 100 MW section is scheduled for connection to the grid and operation by the fourth quarter of 2026.
- Construction began in November 2025, and 200 battery containers (192 installed) house 1,536 racks and 638,976 cells.
- The system stores excess renewable energy and feeds it back during low production periods, generating revenue through price arbitrage.
- Full 300 MW capacity is expected to be operational by the second quarter of 2027.
- Competitors are planning even larger systems, including EnBW's 400 MW/800 MWh plant in Philippsburg and a 900 MW/1800 MWh facility in Waltrop expected by 2028.
