400-foot wind turbine falls in Huron County

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.

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.”
