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.
MidAmerican Energy says it has idled nearly four-dozen electricity-generating wind turbines while workers check them for safety after blades broke off of two similar turbines over the past two months. Those blade failures follow a break earlier this year and one in 2019.
Adair County farmer Curt Beane said the blade crushed the corn below, but nobody was injured. “I work in the field that it came down, and I do have true safety concern,” Beane said. Beane said he does not own the land that the blade fell onto, but he does farm it.
The company submitted records to the county showing the agreements have been reached. Levy said the agreements have been executed and the company would e-mail copies of them to the county. In cases where NextEra could not reach agreements with landowners, the company curtailed operations of turbines close to the county residents’ homes so the machines are within the acceptable noise and shadow flicker limits.
I asked Steve Peters if he knew exactly when the blades in the next section south broke. Peters recalled that, "the blade broke during the morning hours of Dec. 30. Nothing looked wrong at that site until before noon. Steve also said he had heard that 32 turbine sites (96 blades) had blades that needed to be repaired or replaced.
Sibley Fire Chief Kenny Huls says when they were looking for what may have caused the fire, they noticed some charring on the windmill motor, and with the distance and the wind carrying those sparks, he says it appeared to him that perhaps the wind turbine malfunctioned and shot a spray of sparks out into the field.
A College-owned fifty-kilowatt wind turbine at the Conard Environmental Research Area (CERA) sustained a direct lightning strike and is currently inoperable. One of the three blades shattered, and Facilities Management (FM) found the pieces on the ground. The damage occurred on the night of September 8.
The fire destroyed the nacelle, which houses the main components of the turbine, as well as parts of the blades and tower. Strong winds also carried some debris out into nearby fields.
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.
KEOKUK, IA — Three wind turbines impacted the Des Moines River Bridge in Keokuk Saturday morning just after 6:30 a.m.
The MidAmerican Energy Co. is investigating the cause of the Thursday night fire in a wind turbine in Boone County near Beaver.
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 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.
