Approval success for Alterric and VSB: Green light for the Nentzelsrode repowering project

Alterric and VSB Germany have received approval under the Federal Immission Control Act (BImSchG) for the Nentzelsrode repowering project. By replacing older turbines with modern ones, energy output will be nearly doubled while the number of wind turbines is reduced. The approval marks an important step in fully harnessing the wind energy potential in the district of Nordhausen in Thuringia.

As part of the repowering project in Nentzelsrode, five Enercon E-66 wind turbines will be dismantled and replaced with two next-generation Enercon E-138 turbines.

The older turbines, which have been in operation since the late 1990s, each have a capacity of 1.5 megawatts. In contrast, the new E-138 turbines offer a significantly increased output of 4.2 megawatts each. As a result, the total capacity of the wind farm will increase from 7.5 megawatts to 8.2 megawatts. Together, the two new turbines will generate approximately 17,000 megawatt hours of electricity per year – about twice as much as the old wind farm. In theoretical terms, this is enough renewable energy to supply around 5,600 four-person households annually.

Peter Klug, Head of Project Development Germany at Alterric, said: "To successfully implement a decentralised energy transition based on renewable sources, it’s crucial that local residents experience tangible benefits."

Thomas Winkler, Managing Director of VSB Germany, added: "Repowering is essential to address the limited availability of new land. By replacing old turbines with more efficient models on already developed wind farm sites, we can significantly increase the energy generation potential."

VSB Germany obtained the project approval on behalf of Alterric. Alterric will oversee the construction phase. The company expects to complete the dismantling of the old turbines by mid-2025, with preparatory construction work beginning immediately thereafter. Commissioning of the new turbines is planned for early 2026.
