Technical glitch! Giant wind turbine in Moosach is standing still - what now?
New wind power plant in Moosach has been in operation since September 2025, but is struggling with technical faults and sporadic operation.
Technical glitch! Giant wind turbine in Moosach is standing still - what now?
In the municipality of Moosach, a newly built wind power plant is in the headlines - and not for a good reason. Although the system in Fürmoosen only went into operation in 2025, the rotor only rotates sporadically. The problem: technical problems at the manufacturer Enercon, which became noticeable after just a few weeks of operation. Project manager Hans Zäuner expresses clear criticism of the situation and is angry about the standstill of the plant, as construction was on schedule in the summer of 2024.
The wind turbine is an impressive 228 meters high and should be one of the most modern wind turbines. But despite the rapid construction of the foundation and tower, operations are now limited. After a hydraulic defect on the last rotor blade, difficulties arose with the control technology, which led to regular software failures.
Problems are not isolated cases
The fate in Moosach is not without parallels. There are similar technical glitches elsewhere. Two wind turbines in the Thomasburg wind farm in Lower Saxony are at a standstill because cracks were discovered in the rotor blades. Like the wind turbine in Bavaria, these systems come from the same production batch from the manufacturer Enercon. The operator, Stromwerke Schönau (EWS), switched off the systems as a precautionary measure to prevent the damage from spreading. Fortunately, the stability of the wind turbines is not at risk, but the internal cracks measure up to 1.6 meters and are below the norm.
These incidents are part of a larger issue. The Federal Wind Energy Association has been keeping statistics on damage to wind turbines for years. So far, 142 cases have been recorded, with 39 cases of damage to rotor blades. Overall, such damage can be classified as “extremely rare”, especially in view of the around 29,000 wind turbines in Germany.
Market development and cost structure
The wind energy market has undergone changes in the last few decades. While the costs for wind turbines were around 4,000 euros per kW in the 1980s, they have currently fallen to 800 to 900 euros per kW. However, this development is influenced by increasing raw material costs and system integration requirements. There are also other expenses that make up around 30% of the pure system costs. Overall, the project costs for a 2 MW system amount to around 3 million euros.
However, the hope that is aroused by the use of renewable energies is becoming the focus of the discussion due to technical problems. Do investors expect that such situations could lead to financial disadvantages? So far, Fäuner does not see any significant financial losses for investors. Enercon is actively working on solutions to the technical challenges that could impact many other wind projects.
The efficiency of these systems is crucial for implementing the energy transition. In order for wind turbines in Bavaria and beyond to work efficiently, reliable technology is essential. Whether and how quickly solutions will be found remains to be seen and will certainly continue to play a role in the news in the future.
