The turbine is part of the Harvest II Wind Project owned by Exelon Generation, the second part of a wind farm whose first phase began operations in 2008. Harvest II's second phase started operating in 2012. Turbine #7 is located south of Crown Road and east of Gagetown Road.
The team at Heritage is working to determine the cause of the break and the next steps to take to repair it.
The charred remains of the generator of the wind turbine that caught fire late Monday afternoon is clearly visible from the Elkton Road. Seley said there was nothing firefighters could do except watch flames consume the unit themselves. "It's way too high and you are not going to save anything," he said.
Firefighters and deputies were called after a wind turbine caught fire near the village of Elkton. Jeff Smith, an Elkton village official, said the fire, which broke out on April 1, is 300 feet in the air and crews cannot reach it to extinguish the blaze. The turbine is part of the Harvest II wind energy facility placed in service in November 2012 by Exelon and is one of 33 Vestas V-100 (1.8 MW) turbines erected in Oliver, Chandler and McKinley townships.
During Wednesday’s Huron County Planning Commission meeting, Blake Shroll, site manager of Big Turtle Wind Farm, told planners Big Turtle II experienced a failure on Tower 14 on Nov. 28. “We had two pieces of fiber glass fall within 100 feet of the base.
Investigation will begin by company officials after a wind turbine blade failure early this (Wed) morning in Bloomfield Township, west of Port Hope.
Another blade break in Michigan.
Adam Greene, site supervisor for Deerfield, suggested that the Tribune reach out to Vestas. "I have no idea what's going on at this time," he said. ...Two blades in separate turbines similarly broke last October.
A 160-foot (50-meter) wind turbine blade broke in rural mid-Michigan, leaving it dangling above a field. The turbine is one of 75 GE 1.6-megawatt turbines located in Tuscola, Bay and Saginaw counties, Michigan. The project began commercial operation in 2012
Gauger said it’s been determined that the “old style” keyway pitch motor is “defective” and not able to handle the load that is being placed on them by longer blades. He said the motor is essentially trying to adjust itself so that there is less drag. “What happens is on the upswing or the downswing, it’s actually got some slack in there and that’s that clunking noise that people are hearing,” Gauger said.
“Unfortunately with the hazards because of the heavy machinery that's up there, there's not much that we could do until it falls down or wait until the point that it's safe and we can send somebody up there to make an inspection,” says Jay Deboer, the Deputy Chief for McBain Fire Department.
According to Minden City Fire Chief Zach Kramer, a blade snapped on the turbine sometime overnight Wednesday and it's hanging on, blowing debris across the area. The turbine is located right next to Sanilac County's snowmobile Trail No. 20, which is the main trail between Minden City and Deckerville.
A broken wind turbine off of Minden and Ridley roads has officials asking snowmobilers in the area to steer clear of a popular trail near the damaged turbine.
Fifty blades in the Deerfield Wind Energy Project were discovered to have the same issue as the two that broke and dangled from their towers near the intersection of Redman and Iseler roads ...Lack of adhesive was discovered to be the problem, and the defective blades are being repaired, said Jason Sterling, site construction manager of Vestas.
A single blade on two different wind turbines at wind farms bounded by Verona, Redman, Huron City and Kinde Roads were hanging by a literal thread this morning after having apparently snapped in half.
The blades had to be removed as a result of a gear box failure. ...A fire wasn’t involved with the failure and that the black marks seen in the photos are actually grease.
The turbine exceeded designed rotation speeds — 14.4 rpm (revolutions per minute) -- and at that speed, blade tips are moving at about 200 mph, according to Exelon. It created an imbalance as blades picked up speed. At the time of collapse, rotation speeds reached 18 rpm, officials said. “At that high of an rpm, the thing just basically shook itself apart.”
After a hydraulic pump was shut off automatically due to high winds during a winter storm that day, an 'over speed event' occurred as the revolutions per minute of the blades far exceeded what the structure could handle.
On Wednesday, Exelon Wind Generation plans to explain what caused a wind turbine to fall in February ...Exelon officials are scheduled to present a “root cause analysis” Wednesday.
Exelon Wind Generation says it has sent materials to an independent lab for analysis from the site where a 400-foot wind turbine fell.
