ADS-TEC Energy Secures Municipal Battery Storage Contract in Germany, Strengthening Decentralized Grid Infrastructure
ADS-TEC Energy PLC (NASDAQ: ADSE), a global provider of battery-based energy storage and fast-charging solutions, has announced a significant new contract in Germany that underscores the growing role of decentralized energy storage in modern power systems. The company has been selected by Stadtwerke Ludwigsburg-Kornwestheim (SWLB), a municipal utility serving communities in southern Germany, to supply a battery energy storage system (BESS) for integration with SWLB’s wood-fired combined heat and power (CHP) plant.
The project will utilize ADS-TEC Energy’s BESS5000 system, a modular battery storage solution with a total capacity of five megawatt-hours (MWh). Construction of the system is scheduled to begin in 2026. Once operational, the installation will play a key role in enhancing grid flexibility, supporting renewable energy integration, and enabling participation in energy and ancillary service markets.
This contract represents another milestone for ADS-TEC Energy as it continues to expand its presence in Europe’s fast-growing market for decentralized battery storage solutions, particularly within the municipal utility sector.
Supporting Municipal Utilities with Advanced Storage Technology
Municipal utilities across Germany and Europe are facing increasing challenges as renewable energy penetration rises and electricity demand patterns become more complex. Distributed generation from wind, solar, and biomass sources has placed additional strain on local distribution grids, creating a need for flexible infrastructure that can balance supply and demand in real time.
SWLB’s decision to deploy a battery energy storage system alongside its biomass-fueled CHP plant reflects a strategic approach to these challenges. By integrating storage directly at the generation site, the utility can optimize the operation of its assets while reducing pressure on the local grid.
ADS-TEC Energy’s BESS5000 system has been specifically designed to meet the technical and operational requirements of municipal utilities operating regulated distribution networks. The modular architecture allows for scalable deployment, enabling utilities to adapt system capacity as energy needs evolve over time.
For the SWLB project, ADS-TEC Energy will be responsible for technical planning, regulatory coordination, and the overall integration of the system. This includes securing the necessary authorizations and ensuring compliance with applicable grid and safety standards. The company will work in close collaboration with SCHNEPF Group, a Germany-based engineering firm headquartered in Nagold, which brings extensive experience in energy infrastructure implementation.
Decentralized Storage as a Flexible Infrastructure Model
The placement of the battery storage system adjacent to SWLB’s wood-fired CHP plant offers several operational advantages. Proximity to the generation source enables efficient capture of surplus electricity that may otherwise be curtailed, particularly during periods of low demand. At the same time, the system will operate independently through a medium-voltage grid connection, allowing flexible interaction with the local distribution network.
With the BESS5000 in place, SWLB will be able to smooth peak loads, store excess renewable electricity, and release energy back into the grid when demand rises. This capability is increasingly valuable as electrification accelerates across sectors such as transportation, heating, and industry.
Decentralized battery storage also plays a critical role in reducing grid congestion. By absorbing and releasing energy locally, storage systems help alleviate bottlenecks in distribution networks, delaying or even eliminating the need for costly grid reinforcements. This makes battery storage an attractive solution for municipalities seeking cost-effective ways to modernize their energy infrastructure.
Beyond grid stabilization, decentralized storage systems open the door to participation in wholesale electricity markets and ancillary services, such as frequency regulation and balancing services. These market activities can generate recurring revenue streams, improving the overall economics of storage investments for municipal utilities.
Enabling Market Participation and Cybersecure Operations
A key component of the SWLB deployment is the integration of advanced IT systems and cybersecurity measures. As battery energy storage becomes more tightly integrated with digital grid management platforms and energy markets, secure and reliable control systems are essential.
ADS-TEC Energy’s solutions are designed with transparent control logic and clearly defined operational interfaces, ensuring compatibility with utility control systems and market platforms. The company’s approach emphasizes secure, scalable operation, allowing utilities to manage assets with confidence while meeting regulatory and cybersecurity requirements.
The collaboration with SCHNEPF Group will support the seamless integration of these digital systems, ensuring that the storage installation operates reliably within SWLB’s broader energy management framework.
A Strategic Step for ADS-TEC Energy’s European Growth
From ADS-TEC Energy’s perspective, the SWLB contract serves as an important proof point for its decentralized storage strategy in Europe. Municipal utilities represent a particularly attractive customer segment, as they operate long-lived infrastructure assets and typically pursue stable, long-term investment horizons.
Projects like the SWLB installation demonstrate how battery storage can be deployed in a repeatable and scalable manner across multiple sites. Once a technical and operational model has been validated, similar systems can be rolled out to other facilities within a municipal utility’s portfolio, supporting consistent growth and predictable revenues.
Michael Rudloff, Chief Operating Officer of ADS-TEC Energy, highlighted the broader significance of the project, noting that it illustrates how municipal infrastructure providers can benefit from decentralized battery storage integration. According to Rudloff, the company’s robust and modular technology supports both grid requirements and market participation, offering a flexible solution tailored to the needs of regulated utilities.
Strengthening Grid Resilience and Energy Transition Goals
As Germany continues its transition toward a low-carbon energy system, decentralized storage solutions are expected to play an increasingly central role. Biomass-fueled CHP plants, such as the one operated by SWLB, already contribute to renewable and low-emission energy generation. The addition of battery storage enhances the flexibility and efficiency of these assets, enabling better alignment with grid conditions and market signals.
For municipal utilities, investments in battery energy storage are not only about meeting today’s operational challenges but also about preparing for future energy systems characterized by higher levels of electrification and decentralization. Storage systems provide a bridge between renewable generation, digital grid management, and evolving market structures.
The SWLB project positions both the utility and ADS-TEC Energy at the forefront of this transition. By combining local generation with advanced storage and digital integration, the installation serves as a model for how municipalities can strengthen grid resilience, unlock new revenue opportunities, and support long-term sustainability goals.
As construction approaches in 2026, the project is expected to attract attention from other municipal utilities across Germany and Europe, further reinforcing the role of decentralized battery storage as a cornerstone of modern energy infrastructure.
