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.
An official with Applied Materials says its wind turbine on the Dory Road campus in Gloucester should be functioning properly within six months.
The turbine has not been consistently operational since its installation in 2011. The Wilmington-based energy company that installed it, Lumus Construction, eventually defaulted, and Hanover Insurance, the company that held Lumus’ surety bond, became involved, Clarkson said.
The bearing that broke was supposed to last 20 years, but only lasted three. ...The part needed to repair the turbine is estimated to cost $298,000, Boyle has said.
Exelon Wind Generation says it has sent materials to an independent lab for analysis from the site where a 400-foot wind turbine fell.
The blade bent and wrapped around the nacelle of the turbine, flinging a 12-foot piece of blade about 120 yards from the base. DTE Energy regional manager Ron Chriss said GE, the manufacturer of the turbine, will be on site this coming week to make repairs and investigate the cause.
As crews continue to probe why a 400-foot wind turbine fell on a farm field, county planners talked publicly for the first time Wednesday about the incident and aftermath. County Building and Zoning Director Jeff Smith said he was out of town when the turbine fell, on Feb. 25, but went out to the site in Oliver Township on Feb. 29 with township officials.
“It gouged out a nice, big hole, about eight feet wide and three or four feet across." ...“A decision hasn’t been made yet on if the turbine will be replaced.” The company expects a “fact-finding” portion of the investigation to be completed in about a week, she said.
The strong winter storm that hit Michigan this week may be the cause of a wind turbine collapse on the east side of the state.
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 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.
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.
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.
