At the Berching community wind farm between Wallnsdorf and Raitenbuch, a rotor blade fell from a wind turbine on Wednesday, March 18, 2026, at around 9:00 a.m. The turbine involved was a Senvion model from 2012, which, according to the operator, was regularly maintained. The wind turbine was also equipped with a monitoring system for the blade bearings. Despite this, a rotor blade up to approximately 60 meters long and weighing about 12 to 15 tons fell to the ground. The police were quickly on the scene, and local residents also reported the incident. The cause remains under investigation. Employees of the operator, external service teams, and an expert are examining the damage. One point is particularly concerning: the turbine had additional early warning technology, yet the blade fell without the monitoring system detecting any problem. (nn: 18.03.26)
Monitoring System Takes Center Stage After Crash
The operator points out that the system underwent regular inspections. Additionally, a blade bearing monitoring system was installed to detect potential damage early. This is precisely why this technology is now under scrutiny, as there is currently no evidence that the system triggered an alarm in time or clearly identified the defect.
It therefore remains unclear whether the monitoring system failed to provide any indication, whether warning signals were misinterpreted, or whether the damage occurred outside the monitored area. This question is crucial because the turbine suffered a serious malfunction despite maintenance, inspection, and additional technical checks. Until reliable details are available, the most plausible explanation remains that the installed monitoring system did not detect the fault—at least not in a way that prevented the collapse.
Maintenance was carried out as scheduled, yet a serious defect still occurred
According to WINDPOWER, the Regensburg-based company behind the Berching community wind farm, the last maintenance of the affected turbine was in November 2025. The required periodic inspection was also carried out as scheduled in October 2023. Additionally, a blade bearing monitoring system was installed, yet the wind turbine still lost an entire rotor blade. This discrepancy is precisely what makes the incident so significant for the operator, authorities, and local residents.
Clemens Reichl, technical director of WINDPOWER GmbH, stated: “We are doing everything we can to clarify the cause of this very serious incident as quickly as possible.” An expert is now also investigating the case. The operator describes this as the first incident of its kind in its approximately 30-year history. This raises the question of how reliably technical control systems on older wind turbines actually function.
Community Wind Farm of Regional Significance
Police quickly secured the area after the incident. According to media reports, police also temporarily closed a nearby road. Nevertheless, the damage is considerable for the region because the community wind farm not only generates electricity but is also a project with broad local participation.
The wind farm was built in 2012 and 2013 as a joint project between WINDPOWER and Max Bögl. Six of the ten turbines are reportedly owned by a community investment company, in whose profits approximately 2,400 individuals and eight municipalities participate. Therefore, the collapse affects not only a technical installation but also a project with significant economic and political implications. This makes it all the more urgent to investigate why a well-maintained wind turbine with additional monitoring failed to detect such a defect in time.
