Start of construction for Energiequelle GmbH's German repowering project in Minden

Construction work has begun on Energiequelle GmbH’s repowering project at the Minden-Hahlen wind farm in North Rhine-Westphalia (Germany). Three new Nordex N149 wind turbines, each with a total height of nearly 200 meters and a combined capacity of 17.1 megawatts, will replace five older turbines of the types NEG Micon NM 60/1000 and Enercon E-40. With a rotor diameter of 149 meters and modern technology, the new turbines will generate approximately 40,000 megawatt-hours of electricity annually. This represents an increase of around 600 percent compared to the output of the original wind farm.

The project was planned in close coordination with the city of Minden and the relevant authorities. Approval was granted under the Federal Immission Control Act in December 2024. All three turbines are scheduled to be commissioned by the end of October 2026. Once operational in October 2026, the wind farm will supply enough power for about 9,500 households.
