Mahlsdorf wind farm, featuring first use of Nordex 175 turbines, on hybrid towers, commissioned near Berlin

News
UKA Group and Nordex Group have commissioned the Mahlsdorf wind farm in Steinreich, Germany, featuring the first global use of the Nordex N175/6.X turbine. With an installed capacity of 68 MW, the project sets a benchmark for economically utilising sites with moderate wind conditions.
The wind farm consists of 10 Nordex N175/6.X wind turbines (part of the company’s Delta4000 platform), each with a nominal capacity of 6.8 MW. The 175 metre rotors, mounted on 179 metre hybrid towers, are said to capture stronger, more consistent winds at higher altitudes. According to the developer UKA Group, the design and technology ensure long-term site viability. The facility generates about 52,000 MWh annually.
Gernot Gauglitz, Managing Partner of UKA, said that utilising the most efficient turbines is a necessity due to competitive auction environments. ‘From May 2026, I expect the auctions to be oversubscribed by 400% on a permanent basis.’ Gauglitz noted that success in future tenders depends on combining efficient technology with low construction costs and appropriate lease rates.
Karsten Brüggemann, Vice President Region Central of the Nordex Group, described the project as demonstrating the potential of modern technology at medium-wind sites. Nordex manufactured and supplied the turbines and hybrid towers, and also managed the construction of the wind farm.
German wind energy statistics 2025
Germany led European wind power growth last year, adding 5.7 GW of new capacity, primarily from onshore expansion (5.2 GW). Türkiye (2.1 GW) and Sweden (1.8 GW) followed, with all new capacity onshore. These figures are from trade association WindEurope’s new report Wind energy in Europe: 2025 Statistics and the outlook for 2026-2030.
The report states that Germany’s wind fleet has a total capacity of 77.6 GW, meeting 28% of national electricity demand. Onshore wind provides 68 GW, while offshore accounts for 9.6 GW.
Germany’s permitting policy has an average approval timeline of 17 months, ahead of the European average. In 2025, regulators approved a record 20.8 GW of new onshore wind capacity.
EU-wide, investors committed about €18.8bn to onshore projects, with German projects attracting over half (with the balance going to France and the UK), reflecting improved permitting and strong auction results, according to the report. The share of wind in the national power mix reached 28% in 2025. This level of generation places Germany among the top European nations for wind energy penetration. Wind met at least a quarter of electricity demand in only five other European countries during the same period: the UK (31%), Sweden (30%), Netherlands (29%), Finland and Portugal (both 25%).
Germany added 503 MW of offshore wind capacity at two wind farms, installing 28 turbines at Borkum Riffgrund 3 (913 MW) and 13 turbines at He Dreiht (960 MW).
