On 21 October, the storm, named Ignatz, hit with gale-force gusts of wind at speeds of more than 100km/h causing rotor blade damage to two E-138 EP3 turbines, an Enercon spokesperson said.
The "Ignatz" storm caused numerous problems in many regions. More than 60 incidents reported to the Aalen police headquarters - mostly from the Rems-Murr district.
"The cause of the incident is under investigation," TransAlta spokesperson James Mottershead said in an email to CBC News. The area surrounding the wind facility has been closed while the investigation is underway. ...According to the company's website, the Kent Hills wind farm is the largest wind facility in the province, with more than 50 wind turbines.
According to a statement on RAG Montan Immobilien’s website “The plant has completely collapsed, most of the components such as the wings, machine house and the upper steel element are at the base of the plant and in the adjacent forest.” According to local news reports, the incident could be heard several kilometres away.
The wind turbine was completely destroyed by the collapse, as a spokesman for RAG MI announced. All that remained was a 40-meter-high stump made of concrete parts. ... The twin system, which is around 450 meters away, was put out of operation for safety reasons immediately after the collapse became known. "It will not be put back into operation until the cause of the accident has been clarified." According to the municipal utilities, the wind turbine was connected to the grid when it collapsed. According to the Haltern fire brigade, it was not very windy.
Officials in Germany are investigating why a huge wind turbine collapsed just hours before it was due to be officially inaugurated.
The federal Bureau of Land Management confirmed it ordered the halt of operations at the Ocotillo Wind facility following Sept. 16's collapse of a 300-foot wind turbine.
“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.
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.
Two wind turbines along County Road 650 south of Helena were damaged earlier this month, though the cause of the damage still is under investigation. Bryan Garner, director of communications at NextEra Energy Resources, said in an email the turbines at the Skeleton Creek Energy Center were damaged on Aug. 11 and 12.
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.
Ørsted, the Danish energy company that purchased the wind farm from the original developers, Deepwater Wind, said that four of the five turbines were taken offline earlier this summer as a precaution after GE, the manufacturer of the 6-megawatt turbines, identified the stress lines in the turbines.
Ørsted, the company that owns the wind farm, tells 12 News they’re conducting routine maintenance on the turbines. Right now, a spokesperson said they’re in the process of repairing stress lines inside four of the turbines.
Part of a blade on a wind turbine just off Grey County Road 8 southwest of Dundalk broke and fell to the earth last Wednesday morning.
LYFORD, Texas — A wind turbine caught fire in Lyford on Monday.
London-listed TRIG said that routine inspections had identified signs of stress fatigue on certain areas of the support structure of the helihoist on some of the 6MW wind turbines manufactured by GE. “Generation at the wind farm was paused as a precautionary safety measure whilst the root cause of the issue is being investigated,” TRIG said in a statement.
“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.
“An investigation has been launched into the cause of the incident and the best course of action going forward,” added a statement from Vattenfall. “So far, a 500 meter safety zone has been established around the mill, in which ships are not allowed to travel.”
Developers Vattenfall and Ørsted are analysing why Vestas’ V80-2.0MW turbine caught fire at the Danish wind farm. Vattenfall and Ørsted are investigating after a turbine at their co-owned 160MW Horns Rev 1 wind farm off Denmark caught fire.
JOHNSTON COUNTY, OKLAHOMA (KXII) - A wind farm turbine in Johnson County caught fire, after it was struck by lighting during Friday night’s storms.
