The battery storage project in Bad Düben has a capacity of 13.8 MW with a gross storage capacity of 15.2 MWh. Battery cells from Samsung SDI are used. The battery storage system is used to provide system services (in particular primary control power), as well as to generate revenue from optimization on the spot market and from avoided network charges (§ 18 StromNEV) and is connected to the grid of Mitteldeutsche Netzgesellschaft Strom mbH. The battery storage system was completed and commissioned in November 2022.
