DTE Energy regional manager Ron Chriss said a blade on the wind turbine bent and wrapped around the head, or nacelle, of the turbine. “DTE Energy found one piece of blade approximately 12 feet long on the ground about 120 yards away from the base,” Chriss said.
A nearly 400-foot, 485,000-pound wind turbine has fallen down on a farm field at the site of the state’s first utility-scale wind project. Oliver Township Supervisor Larry Krohn said it came down at about 5:20 a.m. in the middle of the field. ...The fall marks the second incident in less than a week in which a wind turbine has failed.
A wind turbine located in Huron County fell over during a winter storm. The turbine was part of the Harvest I wind project commissioned in 2008. Harvest I includes 32 Vestas V82-1.65 MW turbines.
A wind turbine located in Huron County fell over during a winter storm that brought wind and heavy snow to much of the state, but the cause of the collapse is unclear. The Harvest I wind project, commissioned in 2008, includes 32 Vestas V82-1.65 MW turbines.
One of the wind turbines in the first commercial wind project to be done in Huron County came down this morning north-west of Elkton.
Photos taken Monday show the blade broken in at least two spots. The blade, which DTE says is made of carbon fiber and fiberglass, twists overtop the turbine’s nacelle, pointing downward and hanging between two other blades intact.
A wind energy conversion turbine caught fire Friday afternoon, causing responses from both Saunemin and Pontiac fire departments. ...It is, however, a little ironic that the source of power the turbines were trying to capture may have also caused or exacerbated the fire at the turbine.
A wind turbine in northern Livingston County caught fire Friday. ...Streator Cayuga Ridge began operating in March 2010.
A 160-foot, 7-ton blade on one of DTE Energy’s wind turbines sited in Sigel Township, Huron County MI was destroyed. The turbine was one of 40 GE 1.6-100 towers. DTE's Sigel Township installation was placed in-service in October 2012.
Blades breaking aren’t an anomaly in Huron County.
DTE Wind Energy crews are on the scene of a blade separation at the Sigel Township wind park near the corner of Section Line and Finkel Roads.
Catastrophic failure is widely defined as the complete, sudden, often unexpected breakdown in a machine or other system. This winter, there have been four such events reported across the wind industry. With regular wind turbine service and maintenance and the possibility of sophisticated condition monitoring, how is such an embarrassing failure — appearing as it seems out of the blue — still possible?
There were two big booms when it happened, one when it hit and then another when it probably flipped over,” said Fenner resident Dick Foringer, who lives about 900 feet away. ...Editor's note: Mr. Foringer confirmed by phone that the initial impact crater was 323 feet from the base of the turbine. The blade then bounced, and ultimately landed 471 feet from the base.
Fenner town officials said it's the same 187-ton windmill - No. 18 of 20 - that collapsed in December 2009. It was replaced with a new wind turbine, Douglas said.
Suzlon has confirmed local reports of the collapse of a wind turbine in Brazil ...In a local TV video taken after the crash, a tower section appears to have severed and the nacelle and rotor are splayed on the ground, in the sand dunes.
“This information came from concerned local residents but there appears to be no official acknowledgement by the owners of the development nor has the Council or the HSA been informed. This is the usual sequence of events with turbine accidents and we have had a few in the County in recent years.
A number of investigations are believed to be underway after a blade on a huge wind turbine near Drumkeen “disintegrated” at the weekend. ...It is believed the turbine in question was struck by lightning.
Firefighters dealt with a wind turbine converter fire this afternoon near Pontyates.
An out of control wind turbine has caused a road closure in Mojave.
This video was posted on Facebook and YouTube. Few details are provided about the incident including the location and timing of the event. (It is not clear the incident occurred in New Zealand.) Nonetheless, the video demonstrates the type of danger a turbine can pose when sited too close to where people may live or gather.
