DTE has halted construction of the remaining 10 turbines and shut down the entire wind park. “We have ceased all work and operation on the project until we’re satisfied with what the root cause is and that it doesn’t pose a danger of any continued blade failure. We’re working with GE to determine the root cause. It’s still under investigation.”
It was the third turbine to break in Huron County in the last 10 months and the second turbine owned by DTE to break down in that time. In March, a turbine blade in Sigel Township broke ...In addition, a turbine was struck by lightning near Minden City at the Michigan Wind Project 2 in September. The turbine, owned by Exelon Energy also lost a blade and was set to be back online this week.
“The cause for the blade breaking was a carbon failure at the 19-meter mark that was not formed properly,” Buda said. “Failure in the heating oven at the plant caused the blade to break later on.” ...properly made wind turbines can handle wind speeds up to 125 mph.
Unsure of what to do with its broken turbine, Union Township officials have tabled making a decision until the township consults with Central Michigan University. The north Skystream, a $16,634 grant-funded wind turbine installed for research purposes, no longer works, and the city is not sure why.
The wind turbines that were installed on the Genoa Township hall property will be coming down for safety's sake.
It took four months after the initial breakdown to find and obtain a part from Europe at a cost of almost $38,000. Workers installed the new part on Jan. 4, but it failed two days later. The supplier eventually replaced it after another lengthy search. The part was installed April 16. It lasted three days.
Scott L. Simons, DTE Energy spokesman, previously told the Tribune that the utility received an alarm at 1 a.m., and later found that one of the blades at the Sigel site appeared to be damaged. Part of a blade had fallen and was on the ground. ...Last year, two GE-manufactured turbines experienced broken blades in East Central Illinois.
Officials said Friday that there isn't any new information indicating why a wind turbine blade broke off early Monday morning during a low-wind period at DTE Energy's Thumb Wind Park. ...Last year, two GE-manufactured turbines experienced broken blades in East Central Illinois.
DTE Energy has no idea why a portion of a wind turbine blade broke off early Monday morning during a low-wind period at one of the utility's sites in the Thumb Wind Park. "This matter certainly is under investigation," said Scott L. Simons, DTE Energy spokesman.
One of DTE Energy's wind turbines in Sigel Township is motionless after one of the blades on the structure failed during low wind conditions. Pieces of the blade were lying on the ground near the tower. No details as to the cause of the break were available.
"We're in the process of developing an operational guideline that we're going to make universal across the county so we're all operating on the same page so if we have to go to a mutual aid call with another fire department, we're all operating the same way." He says there are 15 volunteer fire departments covering all of Huron County.
The Denmark Township board voted in December to renew its wind moratorium for six months through July 31, 2013. Denmark Township clerk Chuck Heinlein said the township planning commission faces a complex process of determining areas suitable for placing turbines. Heinlein said certain complications for wind development come from the amount of air travel in Denmark Towship.
While wind energy is controversial across Northern Michigan, some residents in the Ludington area say this project actually puts the lives of residents in the community at risk. That is because they believe several of the wind turbines are going to be built too close to gas lines.
Construction crews will have to assess the damage to a wind turbine that caught fire in Missaukee County.
An employee of the wind park responded early Thursday morning to "trouble shoot" problems with the wind turbine grid. It was determined someone using a firearm had shot the 34,500 volt transformer. ...A hole was found in the transformer's radiator resulted in damage, which caused oil to leak out.
Smith said brief power outages experienced in the area cause the three turbines to instantly stop and recoil, which fatigues the blades in the area where they are likely to break. When the blades are new, they're more flexible and durable. ...we are going to direct all maintenance employees to approach away from the blades and keep visitors away. The blade ejection happens rarely, but we need to err on the side of safety.
Consumer's Energy hopes to build a wind farm just south of the Mason County Airport, made up of 56 turbines. Nearly 75% of them exceed the height requirements because they are so close to the airport.
Public utility officials may end up spending tens of thousands more than anticipated on a broken wind turbine. Traverse City Light & Power's towering wind turbine along M-72 in Leelanau County's Elmwood Township has been idle for more than three months. Officials originally said a failed generator bearing would cost between $15,000 and $20,000 to repair. Then another problem arose.
A road in Missaukee County was closed for several hours Sunday afternoon and three homes were evacuated as a safety precaution after construction workers became concerned about the stability of a newly-installed 400-foot wind turbine. ...[the homes] were still evacuated out of an abundance of caution in terms of possible flying debris.
Spurred by idled windmills at Laker Elementary School near Pigeon, the Michigan Public Service Commission has launched a statewide investigation into the interconnection of independent power projects with electric utilities.
