DTE to replace 33 turbine blades

The replacement of the blades comes after a blade broke into three pieces in November in Chandler Township. “This is an issue that is greater and bigger than just what is happening here in Huron County,” Chriss said. All of the blades that need repair are located within the Echo Wind Park according to DTE.

Another GE turbine blade breaks off, leading to further investigation

“Out of caution, all turbine commissioning and turbine operations at the wind farm have been suspended,” Invenergy says. “We are working with GE, the turbine manufacturer, to determine the cause of this incident. Following a GE blade break on Nov. 7, utility DTE Energy has also ceased work on its 112 MW Echo Wind Park in Michigan. Scott Simons, a DTE Energy spokesperson, recently told NAW that GE was performing a reliability test on a turbine when the blade fell.

‘Here at DTE, we have a lot of questions as well’

The blade that broke was going through a testing period but hadn’t been fully commissioned, according to DTE. CO-84 was turning when it broke into the three pieces. Two parts of the blade fell right underneath the turbine, while a third piece traveled 80 feet and landed on the access road to the turbine. “As a result of the failure we have shut down Echo,” Chriss said at the meeting.

GE blade crashes to the ground at DTE wind farm

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.”

DTE explains broken turbine blade

“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.

Predictions of turbine's demise premature

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.

Solar panels potential hazard to firefighters

"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.

Airstrips may limit local wind development

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.
