"Significant Dangers": Experts to conduct more rigorous testing of wind energy facilities.
Burning turbines, broken blades, crashed machine parts - damage to wind turbines are causing a stir. But do these accidents really matter? The Association of Technical Inspection Associations (VdTüv) says: Yes! and it's demanding a comprehensive inspection requirement for wind turbines: "Despite significant dangers and numerous accidents so far only individual parts of these systems are tested according to completely different regulations," criticized Tüv-Verbandschef Joachim Bühler.
The FDP also agrees. The state chairman Michael vom Baur pleads for "a regular maintenance and certification of these plants" as is required for "every truck and every ship". This is the only way to guarantee a "responsible handling of operational safety".
Baur calculates: Since 2016, there have been 16 fires, 15 blade and nacelle accidents and 4 tower damages involving wind turbines in Germany. With tons of equipment and high rotor speeds, there is a "high risk potential for people and buildings in the area".
Also in MV - there are currently about 2000 wind turbines on the mainland - there are accidents. At the beginning of August, the turbine at a plant near Krackow (Vorpommern-Greifswald) burned out. In January and May, wind turbines at Löcknitz (Vorpommern-Greifswald) and Ganschendorf (Mecklenburg Lake District) caught fire after lightning strikes. An incident in December 2016 at Grimmen made news headlines when a windmill broke off at a height of 25 meters and huge machine parts crashed onto a field.
The German Wind Energy Association (BWE) knows the figures submitted by the FDP and rejects the Tüv requirement. "One must assess the levels of damage in relation to the approximately 30,000 plants in Germany," says spokesman Christoph Zipf. If only about one per thousand incidents occur, it shows that the facilities are generally "very safe".
In general, the "large number of tests" conducted make the plants "among the safest structures in the landscape," emphasizes BWE Managing Director Wolfram Axthelm. In addition to construction supervision and safety inspection, the plants would be subjected to six-monthly maintenance. Axthelm: "In addition, every two to four years there are recurrent examinations by recognized experts." Even the wind energy expert and head of the Greens, Johann Georg Jaeger, considers studies "unnecessary". Jaeger: "The insurers make sure that there are proper maintenance concepts, otherwise they would have to pay the damages." However, older facilities whose manufacturers are no longer in business, could be examined in more detail and more frequently.
