He said a wind turbine four miles south of Zearing off U.S. Highway 65 was damaged by the tornadoes that ripped through Iowa earlier this summer, leaving one blade dangling. Then, lightning struck it during the storms this weekend.
Wind-warped turbine sits still about a half mile north of E29 on Highway 65. One of the blades was bent like a rabbit ear due to storm-related winds that came through Central Iowa last week. It was the only one with this kind of damage in the pod of turbines.
KEOKUK, IA — Three wind turbines impacted the Des Moines River Bridge in Keokuk Saturday morning just after 6:30 a.m.
A massive wind turbine caught fire Thursday night near Beaver in Boone county.
The MidAmerican Energy Co. is investigating the cause of the Thursday night fire in a wind turbine in Boone County near Beaver.
This 2.5 MW Clipper model C-96 turbine, part of NextEra's Endeavor I Wind Energy Center, burned for hours before this video was taken. The video shows the turbine's massive blade fall to the ground after first standing on its end before collapsing into a trail of black smoke and flames. The Endeavor I facility is located in Osceola County, Iowa. The turbines stand 420 feet tall including the 153-foot long blades; rotor diameter of 314-feet (96 meters). The 100 MW facility includes 40 turbines and was placed in service in 2008.
Garner said the turbine in question is a 2.5 mega-watt Clipper turbine, located on the organization's Endeavor I Wind Energy Center in Osceola County. There is a second Endeavor energy center also located in the county, both beginning operation in 2008.
The Ocheyedan Fire Department was called to the scene ...They stood by after the decision was made to let the fire burn itself out.
"On approach, we could see a lot of heavy smoke coming from the turbine," said Manchester. "As we got closer, we were able to see there was quite a bit of flame coming from the top portion of the turbine where the blades attach. We were advised by Iberdrola not to approach the turbine, just due to the safety factor, because there was a lot of debris that was burning and falling off.
A blade on a wind turbine broke loose and landed in a field in Adair, Iowa. KCCI reports officials said they are still trying to figure out what went wrong. The turbine manufacturer is leading an investigation into the accident.
The wind turbine that helps to power the electricity for the Clay Central-Everly school district needs repair. Right now, the turbine is running at a reduced capacity ...The cost of the repairs is approximately $26,000, and the board is concerned that the output, once fixed, won't save the district enough electricity to offset the overall cost.
The wind turbine is part of the Barton II wind farm owned by Iberdrola Renewables is on land southeast of Bolan in Worth County. Jan Johnson of Iberdrola said the fire occurred in the nacelle, the portion of the turbine that houses all of its component parts. She could not give an estimate of damage.
A wind turbine near Grafton caught fire Tuesday, May 22 2012. The flames were strong as the smoke streamed from the tower. Fire crews didn't get close at first because of burning debris falling down. Duration: 1 minute 2 seconds
A wind turbine near Grafton caught fire Tuesday afternoon. The flames were pretty strong for a while as the smoke streamed from the tower. Fire crews didn't get too close at first because of burning debris falling down.
Akron-Westfield Community School District's 165-foot-tall wind turbine now stands idle on Akron's skyline. A costly repair means the school board is facing the decision of possibly trying to sell the turbine.
The job ground to a halt after workers for Industrial Contract Services placed a 17-ton rotor assembly atop the 246-foot tower. A blast of wind spun the blades prematurely, according to Waverly Light and Power, and all but the base of the turbine fell to the ground.
Residents reported to the National Weather Service that two wind turbines were damaged. One had a propeller bent in half and the second had a propeller with the tip snapped off.
Turbine components weighing 50-tons fell 246 feet to the frozen ground on Saturday (Feb 20, 2009) when the blades of a turbine under construction east of Waverly caught wind and started rotating at a speed reaching 60 rpm. The hub housing the generating components of the Cannon II turbine and the structure's three 177-foot blades collapsed after spinning for hours at the mercy of the wind, says Waverly Light and Power General Manager Diane Johnson. A gust caught the blades prematurely on Friday because, prior to the installation, they were not turned in a way that would have prevented them from catching wind until construction was complete, according to a press release issued by the municipal utility. "It could have spun for days," Johnson says. On Monday, as the mangled blades lay at the base of the tower, construction crews worked to dismantle the structure's top and middle sections to reinforce the turbine. Crew and neighbors were evacuated overnight until the structure collapsed under its own weight. Duration: 10 minutes
Blades the length of almost two school buses from a wind turbine owned by Akron-Westfield School District rest on the ground while repairs are underway. The turbine's gearbox was also brought down using a tall crane to reach the top of the 11-year-old structure's 165-foot-tall tower, which is much higher than people realize, said Dwain Wilmot, A-W technology coordinator. "You can see Vermillion (S.D.) on a good day," Wilmot said, if you stand on the top of the wind turbine tower. "I've only seen it once or twice."
