Planned 400 MW battery storage facility with at least 800 MWh capacity and the ability to deliver maximum output for at least two hours. Planned equipment includes more than 200 lithium-ion battery units, more than 100 inverters, over 50 medium-voltage transformers, two high-voltage transformers and two switch panels. It is to connect via the Hilgenberg substation, which Amprion is building less than 50 metres away. Before foundations can be laid, the 8.5-hectare site in the southern part of the industrial area requires preparation.
