The battery storage project in Brilon, in the Hochsauerlandkreis district, has an output of 102 MW and a gross storage capacity of 204 MWh. 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 Westnetz GmbH network. Construction of the plant is scheduled to start in summer 2025.
