Hitachi Energy Inaugurates Expanded Transformer Factory in Germany

12 Nov 2026
Hitachi Energy has inaugurates its expanded power transformer manufacturing facility in Bad Honnef, Germany, completing a project announced in February 2024 with an investment of more than $34.8 million (€30 million).

The site, operating since 1906, manufactures large power transformers for electricity transmission and distribution. The expansion brings the facility’s footprint to more than 15,000 square meters and includes modernization measures and process improvements intended to increase manufacturing capacity and operational performance.

As production capacity grows, factory audit processes help assess manufacturing practices and supplier capabilities. For large power transformers, advanced insulation solutions are also important to equipment performance and long-term reliability.

The investment was announced amid rising demand for transformers supporting grid development and the energy transition. The added capacity contributes to the regional manufacturing base as utilities invest in network expansion, equipment replacement and grid modernization and resilience. The Bad Honnef facility is part of Hitachi Energy’s European manufacturing network.
