Another storage project in Bavaria is taking shape: Stadtwerke Feuchtwangen will soon be capturing surplus electricity in the battery modules of a 10 MW container system.

In Middle Franconia, the energy transition is about to reach another milestone. Stadtwerke Feuchtwangen plans to put a reservoir for 20,000 kWh of electricity into service this summer.

The Bavarian town's utility is spending around 10.7 million euros on the battery storage project. Siemens AG was awarded the contract for the project in November 2023. According to the agreement, the technology group will also be responsible for inspection and maintenance for at least the first five years of operation.

The storage facility will have a capacity of 10 MW and will be able to absorb green electricity from the municipal utilities' generation plants in order to market it and also transmit it to domestic customers. At the same time, it will relieve the pressure on the 20 kV grid of the municipal utility and intervene in the event of peak loads.

The storage system will also be able to store green electricity for the external market during "dark doldrums", i.e. the simultaneous absence of sun and wind. According to a press release, Feuchtwangen is working with a Siemens partner to market the electricity flexibly.

The storage modules and containers have now reached their location next to the Schleifmühle substation. The battery is set to go into operation in June. Those responsible in the municipality, which is home to 13,000 people, are considering expanding the facility in the future. The construction of the battery storage system also allows for this as a precautionary measure.
