Windmill collapse shuts down Ocotillo wind farm

“All turbines at the facility have been shut down pending completion of the root cause analysis. Siemens Gamesa is the turbine manufacturer and is leading the investigation into the root cause,” Siemens spokesperson Myca Welch stated in an email Thursday afternoon. Welch did not immediately provide information on when the facility was taken offline or a timeline on when it might resume operation.

Ocotillo wind turbine collapses -- AGAIN

Residents in Ocotillo are voicing concerns after yet another wind turbine collapse at the Ocotillo Wind Energy facility. There were no injuries or damage to other structures when the 300-foot-tall turbine crashed to the desert floor at the trouble-prone facility on Thursday, September 16. But residents are raising serious questions over public safety at the site, which produces energy to SDG&E to power the San Diego region.

Block Island offshore wind farm still down for maintenance and safety inspections

Workers at the Merkur wind farm in the German North Sea found signs of stress fatigue on the support structures of the “helihoist” platforms on some of the project’s GE Haliade turbines. Power generation at the 396-megawatt array was temporarily halted to come up with a solution to the problem, but the wind farm has since come back online. In June, Ørsted said it had put the five-year-old Block Island Wind Farm “on pause as a precautionary safety measure” to see if similar problems had arisen with the platforms at the top of the turbines that equipment and workers can be lowered onto from helicopters.

Broken, burned-out towers pose possible threat to public

“I am not someone whose nerves get on edge very easily, but I didn’t want either myself or my people close to it. What I saw gave me fear,” said Wreath. “I left with many more concerns and questions than I had arrived with.” The 120-megawatt capacity project — located along the Oklahoma-Texas state line between Guymon and Hardesty — went operational in 2012 and contains 60 towers within Oklahoma. About nine towers show signs of catastrophic failure, where portions or entire blades are missing or nacelles at tower tops have burned. Dozens of other towers are locked down, either because of internal damage that can’t be observed without a detailed inspection or because of other problems that could be impacting their operations.

Locust Ridge wind turbine burns

Locust_ridge_turbine_fire_3_thumb Avangrid Renewables, previously known as Iberdrola, built and now owns and operates the Locust Ridge I and II wind energy facilities. Phase I consists of 13 Gamesa G87 2.0 megawatt turbines. Phase II includes 51 Gamesa G83 2.0 megawatt turbines. The phases were placed in service in 2007 and 2009 respectively. There have been at least four other turbine fire events at the Locust Ridge facility since the turbines were erected including in December 2020, May 2018, March 2014 and in May 2009.

Another Vestas wind turbine blade breaks and falls, this time in Iowa

MidAmerican Energy, has idled more than 40 wind turbines at Iowa wind farms after a 50 metre-long turbine blade broke off and fell into a field last week. ...“The turbine that had the blade failure last week is the same type of turbine that had a blade failure last month in Adair Countym” he said. “They also had the same type of lightning system in them that channels lightning from a strike near a wind turbine blade down into the ground safely.
