ADS-TEC Energy has been awarded a contract by a municipal utility in southern Germany to deliver a 5MWh battery storage system for integration with its biomass combined heat and power plant.
The project for Stadtwerke Ludwigsburg-Kornwestheim (SWLB), scheduled for construction in 2026, will use ADS-TEC Energy’s BESS5000 modular system, designed specifically for regulated municipal distribution grids. The company will oversee technical planning, authorisations and IT and cyber security integration, working alongside engineering partner Schnepf Group.
By installing the battery storage system adjacent to the biomass facility, SWLB will be able to smooth peak loads, store surplus renewable electricity, and relieve pressure on the local grid. The flexible setup connects via the medium-voltage grid, enabling independent operation while benefiting from proximity to generation.
Decentralised storage projects such as this provide grid stability, reduce congestion and support renewable integration. They also open access to energy and ancillary service markets, creating recurring revenues for municipal operators.
“SWLB’s project demonstrates how municipal infrastructure businesses can benefit from the integration of decentralised battery storage,” said Michael Rudloff, COO of ADS-TEC Energy. “Our robust technology supports grid requirements and allows participation in energy markets. Our modular battery solutions are built for these applications with clearly defined technical and operational interfaces, transparent control logic and a secure, scalable operating concept.”
