ADS-TEC Energy wins contract for SWLB municipal battery storage project in Germany

Key Terms

battery energy storage system technical

A battery energy storage system is a device that stores electricity for later use, much like a rechargeable battery for a phone or laptop. It allows energy generated during times of low demand or from renewable sources to be saved and released when needed, helping to balance supply and demand. For investors, it represents a way to support reliable energy flow and capitalize on the increasing demand for flexible, clean power solutions.

• German municipal utility, SWLB, has selected ADS-TEC Energy’s 5 MWh battery energy storage system for integration with its biomass power plant.
• The BESS5000 system provides grid flexibility and enables participation in energy and ancillary service markets
• This project will act as a reference for decentralized storage in the regulated European distribution grids market.
• ADS-TEC Energy battery storage systems deliver recurring revenues from grid services and allow participation in energy markets

NÜRTINGEN, Germany & LUDWIGSBURG, Germany--(BUSINESS WIRE)-- ADS-TEC Energy PLC (NASDAQ: ADSE) today announced it has won a contract from Stadtwerke Ludwigsburg-Kornwestheim (SWLB), a municipal utility in southern Germany, to supply a battery energy storage system for its wood-fired combined heat and power plant. SWLB chose ADS-TEC Energy’s BESS5000 system with a capacity of five megawatt-hours (MWh) for a project scheduled for construction in 2026.

ADS-TEC Energy's BESS5000 battery energy storage system selected for SWLB's power plant in Germany

The BESS5000 modular storage system is designed to meet the requirements of municipal utilities with regulated distribution grids. For the SWLB deployment, ADS-TEC Energy will manage technical planning, securing authorizations, and the integration of IT and cybersecurity in partnership with the engineering firm SCHNEPF Group, based in Nagold, Germany.

Decentralized storage as a scalable infrastructure model

Using ADS-TEC Energy battery system. SWLB will be able to smooth peak loads, store surplus renewable electricity, and ease pressure on the local grid. By locating the system right next to the biomass power plant, the solution’s flexible setup benefits from proximity to the energy generation while being operated independently via the medium-voltage grid connection.

Decentralized storage projects make it easier for distribution grids to accommodate renewable energy, while reducing congestion, and improving grid stability. At the same time, they allow customers to participate in energy and ancillary service markets, creating new recurring revenues.

Michael Rudloff, COO of ADS-TEC Energy, commented: “SWLB’s project demonstrates how municipal infrastructure businesses can benefit from the integration of decentralized battery storage. 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. We look forward to successfully implementing this project together with SWLB and the SCHNEPF Group.”

Municipal utilities as proof points for repeatable growth

For ADS-TEC Energy, the project represents another step as it expands its footprint in the European market for decentralized battery storage. Municipal utilities provide a stable and replicable application environment for storage systems that combine grid services with market participation. SWLB’s installation demonstrates how decentralized battery storage systems can be rolled out across multiple sites, supporting grid resilience while enabling long-term, predictable revenue streams linked to infrastructure operation.
