The plant, spanning 20,000 square meters, is scheduled to be completed by spring 2027, with series production beginning in October of that year.
“With the new battery system production facility in Luhe-Wildenau, we are making a clear commitment to Germany as a production and innovation hub,” said Karl Blaim, CFO of Siemens Mobility. “We are investing specifically in key technologies, creating high-quality jobs in the region, and strengthening the competitiveness of the domestic rail industry.”
The facility will manufacture complete battery systems, including an innovative Battery Management System (BMS) developed with Munich-based Stercom. These batteries are designed to meet much higher durability and robustness standards than automotive solutions, with storage capacities of around 500 kWh for regional trains and up to 2,000 kWh for locomotives.
Bavarian Minister of Economic Affairs Hubert Aiwanger welcomed the project as a boost to both the local economy and the wider region. “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,” he said.
Battery pre-assembly is already taking place in Luhe-Wildenau. The expansion will allow Siemens to scale up to producing 120 megawatt-hours of battery capacity per year under three-shift operation. The project includes investment in automation technologies and advanced welding processes, supported by €2.7 million in Bavarian state funding.
