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.

Last month, Dundonnell was also hit by a fallen blade at one of its Vestas turbines, which brought production across the wind farm to a halt for a few days as the cause was investigated. Campbell says it is clear that the blade fell because bolts holding it to the hub became loose, but the question of why those bolts became loose is still under investigation.

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.
