Siemens Mobility has begun constructing a new battery system manufacturing facility in Luhe-Wildenau, Bavaria, Germany. The facility, which will cover an area of approximately 20,000m², is expected to employ up to 200 people and produce battery systems for regional trains, locomotives, and external customers. The total investment in the project is around €35m, with Siemens Mobility contributing €22m and the Free State of Bavaria providing €2.7m through state funding programs.
The new facility will focus on developing a modular battery family and a battery management system (BMS) in collaboration with Stercom, a Munich-based company. The BMS will monitor and control the batteries, and additional funds will be allocated to production and automation technologies, including welding processes. The facility is scheduled to be completed in spring 2027, with series production expected to commence in October 2027.
Once fully operational, the factory is expected to reach an annual output of up to 120MW of battery capacity with three-shift operations. Battery cells will be supplied by external companies such as Toshiba, and Siemens Mobility will handle the integration of these cells into the final systems. The pre-assembly of battery systems already takes place at the Luhe-Wildenau location, and the new facility will establish full-scale system production at the site.
The development of the site involves cooperation with Dirnberger Real Estate and DIMONDA Projektbau, which are responsible for site management and project delivery. The project is expected to drive Bavaria forward technologically and economically, with the production of state-of-the-art train batteries being a key, future-oriented field. The battery systems being developed will combine strong acceleration performance with high energy capacity for long-distance travel, resulting in more powerful and efficient trains.
Siemens Mobility’s commitment to Germany as a production and innovation hub is evident in this project, with the company investing specifically in key technologies, creating high-quality jobs in the region, and strengthening the competitiveness of the domestic rail industry. The new facility is expected to make a significant contribution to the development of sustainable and efficient rail transportation, and its completion is eagerly anticipated.
