The move comes in response to rising global demand for large transformers, which are vital for power grid expansion. Transformers are used at nearly every grid node to connect voltage levels and enable long-distance electricity transmission. Siemens Energy’s Nuremberg facility produces units for international energy projects, including offshore wind farm connections, grid stabilisation, and cross-border electricity exchange.
The factory currently employs nearly 1,000 people and has been manufacturing transformers since 1912. The expansion will add about 16,000 square metres to the facility, boosting production capacity by approximately 50%. Construction will take place alongside ongoing operations, with the new production areas expected to be completed by 2028.
The Free State of Bavaria is supporting the project with up to €20 million in technology funding, aiming to strengthen Nuremberg as a centre for innovation, research, and development. Söder said: “Transformers and converters from Nuremberg are essential for secure power grids and an important building block for the energy transition. Siemens Energy’s technology is a prerequisite for successful climate policy – and the Free State is doing everything in its power to promote the transformation. Congratulations to everyone involved in today's ground-breaking ceremony. A future full of energy is emerging in Nuremberg!”
Christian Bruch, CEO of Siemens Energy, highlighted the importance of collaboration: “Germany remains attractive when business and politics take responsibility together. Siemens Energy has 113 years of experience in transformer manufacturing in Nuremberg, highly qualified employees with the necessary expertise, and strong infrastructure. These are the right conditions to continue delivering key technologies for the energy transition from Germany to the world.”
This investment follows a €90 million commitment announced last year at the same site for a new converter production facility. Altogether, Siemens Energy has invested approximately €1 billion in Germany over the past three years. In 2024, the company created about 1,300 new jobs in the country, with up to 1,500 additional roles expected by the end of 2026.
The Nuremberg expansion reinforces Siemens Energy’s role in providing critical technology for global energy infrastructure while supporting regional employment and innovation. With growing demand for grid stability and renewable integration, the project marks a significant step in scaling up production to meet international energy transition needs.
