The UKA Group and the Nordex Group have commissioned the Mahlsdorf wind farm as planned and in full. With an installed capacity of 68 MW, the project sets a technological benchmark for the economical use of sites with medium wind conditions.
The wind farm consists of ten Nordex N175/6.X wind turbines. These turbines belong to Nordex's Delta4000 platform and are designed for high energy yields while simultaneously reducing the levelized cost of electricity (LCOE). The turbines, with an installed rated capacity of 6.8 MW, combine maximum vertical upwind performance with a 175-meter rotor. 179-meter-high hybrid towers, developed by Nordex, position the rotors in more consistent, stronger wind flows with less turbulence – a crucial factor for increased energy yield, especially in inland areas. Mahlsdorf is the first wind farm project worldwide to utilize this turbine type with these particularly tall hybrid towers.
Efficient land use and high yields
With the Mahlsdorf wind farm, UKA underscores its approach of developing permit-eligible sites as economically as possible for all stakeholders through modern turbine technology and an efficient park layout. The park will generate enough electricity annually for approximately 52,000 three-person households, thus making a measurable contribution to regional energy security and the reduction of CO2 emissions. Nordex was not only the manufacturer and supplier of the wind turbines and hybrid towers for the project, but also responsible for the design and construction of the wind farm.
Long-term partnership pays off
The Mahlsdorf wind farm is part of a comprehensive project pipeline that UKA is implementing in Germany together with Nordex. Close coordination between project development, turbine manufacturer, and construction company was a key factor in ensuring on-time completion.
Participation in the wind farm – municipal involvement through the wind power euro
Since 2020, the Brandenburg Wind Energy Plant Levy Act (BbgWindAbgG) has required plant operators to pay €10,000 annually per wind turbine to municipalities whose land lies within a 3,000-meter radius of the turbine's location. From 2026, the levy will be capacity-based – specifically, €5,000 per installed megawatt.
Furthermore, UKA voluntarily shares financially with the neighboring municipalities in accordance with Section 6 of the Renewable Energy Sources Act (EEG) of 2023, depending on the actual amount of electricity fed into the grid. The project developer can offer the surrounding municipalities a share of 0.2 cents for every kilowatt-hour generated locally. Municipalities whose territory lies within a 2.5-kilometer radius of the plant are eligible. These contributions are not subject to municipal revenue sharing. Therefore, the municipalities are free to decide how to use them, for example, for infrastructure projects, investments in daycare centers and schools, the financing of childcare, playgrounds and recreational facilities, or the funding of local clubs and associations.
Statements regarding commissioning
Gernot Gauglitz, Managing Partner UKA:
'Especially under the current highly challenging competitive conditions in the tenders, it is essential to start with the most efficient turbine in order to prevail. From May 2026 onwards, I expect a sustained oversubscription of 400% in the tenders. Only the project developer where everything is just right – by which I mean the one with the efficient turbine, low construction costs, sufficient wind, and competitive lease rates – will succeed. UKA therefore invested in this new turbine type very early on and is thus able, together with its premium partner Nordex, to be successful in future tenders despite the immense competition.'
Karsten Brüggemann, Vice President Region Central of the Nordex Group:
'The Mahlsdorf wind farm is a true flagship project for Nordex and marks an important milestone in our technology development. With the first-ever commissioning of an entire wind farm with N175/6.X turbines, we are demonstrating the potential that modern turbine technology can unleash, especially at sites with moderate wind conditions. This world premiere in Mahlsdorf is due in no small part to our long-standing and trusting partnership with UKA. From project development and technical design to on-site implementation, close coordination among all parties involved was crucial to its success. For us, this project sends a strong signal for the further expansion of wind energy in Germany, for our partnership with UKA, and for the competitiveness of innovative technologies made by Nordex.'
