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.
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. 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 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.
