Iowa: Nextera Wind Turbine Blaze

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.

Fire damages wind turbine near Westboro

"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.

School board discusses next steps for wind turbine

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.

Iberdrola turbine burns

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

Wind catches blades, crashes turbine

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

School's wind turbine's energy production on hold

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."

Wind crashes Waverly turbine

Part of wind turbine breaks and lands in open field

Part of a wind turbine under construction broke apart Saturday morning. The problem started Friday when construction crews were installing a second wind turbine for Waverly Light and Power. During the process, a construction error caused the rotor and blades to start moving in the wind prematurely - spinning uncontrollably and unable to stop until it broke.

An unexpected problem has occurred with construction of second wind turbine

The construction company, ICS of North Dakota, lifted the wind turbine rotor assembly, to which the blades attach, 246 feet high into place late yesterday afternoon. After it was lifted it was discovered the blades were not ‘feathered' or turned properly so they could not catch the wind. In the position the blades are in, the wind caught the blades causing them to spin. When this was discovered, the Bremer county sheriff's department was notified and all personnel were evacuated, including two homeowners who were outside of the recommended danger zone.
