Siemens Mobility has begun construction on a new battery system production facility in Luhe-Wildenau, Bavaria. The 20,000-square-meter plant will manufacture battery systems for regional trains, locomotives, and external customers, creating up to 200 jobs. The project carries a total investment of approximately €35 million, with Siemens Mobility contributing about €22 million and the Free State of Bavaria providing a €2.7 million subsidy through state funding programs. Building completion is scheduled for spring 2027, with series production planned to start in October 2027.
“With the new battery system production facility in Luhe-Wildenau, we are making a clear commitment to Germany as a production and innovation hub. We are investing specifically in key technologies, creating high-quality jobs in the region, and strengthening the competitiveness of the domestic rail industry. At the same time, we are making an important contribution to the mobility transition and sending a strong signal for the future viability of Germany as a business location,” said Karl Blaim, CFO of Siemens Mobility.
“This project will drive Bavaria forward, both technologically and economically. The production of state-of-the-art train batteries is a key, future-oriented field that will benefit not only Luhe-Wildenau and the Upper Palatinate, but Bavaria as a whole. Siemens Mobility is developing battery systems here that combine strong acceleration performance with high energy capacity for long-distance travel, so we can look forward to more powerful and efficient trains. At the same time, many high-quality jobs will be created in the region. This project will therefore strengthen our business location in the long term,” said Hubert Aiwanger, Bavarian Minister of State for Economic Affairs.
The facility will produce fully integrated battery systems, including an innovative Battery Management System (BMS) developed in collaboration with Munich-based Stercom. The BMS is designed to monitor and control the battery, ensuring safe operation while maximizing efficiency and service life. Battery cells will be sourced from external suppliers such as Toshiba, and Siemens Mobility will oversee system integration. In full three-shift operation, the plant will have an annual capacity of up to 120 megawatt-hours.
Karl Blaim, CFO of Siemens Mobility, noted that this investment reinforces Germany’s role as a production and innovation hub, supports high-quality job creation in the region, and boosts the competitiveness of the domestic rail industry. Bavarian Minister of State for Economic Affairs Hubert Aiwanger emphasized that state-of-the-art train batteries developed at the facility will deliver strong acceleration performance and high energy capacity, benefiting both the regional economy and the broader Bavarian business location.
Since 2017, Siemens Mobility has held a leading market position in battery-electric regional trains and is extending its portfolio to include battery-electric locomotives for freight. These applications demand robust, durable battery systems with typical storage capacities of around 500 kilowatt-hours for regional trains and up to 2,000 kilowatt-hours for locomotives.
Pre-assembly of battery systems is already underway in Luhe-Wildenau. The new full-scale production plant will build on this expertise by integrating advanced automation and state-of-the-art welding processes. The site development and project execution have been carried out in partnership with Dirnberger Real Estate GmbH and DIMONDA Projektbau GmbH.
By expanding its battery production capabilities, Siemens Mobility aims to support the transport transition, strengthen Germany’s industrial base, and signal confidence in the nation’s long-term competitiveness.
