GE blade snaps in Michigan
DTE Energy shuts down construction at 112MW Echo wind project
DTE Energy is investigating after a blade broke off a turbine at the 112MW Echo wind project under construction in Michigan.
The turbine blade broke in half on 7 November, with part of the blade found at the base of the tower, DTE spokesperson Scott Simons told reNews.
“Construction of the turbine was complete,” said Simons. “The incident occurred during a six-hour reliability test.”
Winds were blowing between 10 and 15 miles per hour at the time.
The turbine was the 60th of 70 GE 1.6MW machines to be constructed at Echo. The first tranche of turbines were commissioned in October and fifty-nine were operational when the accident occurred. No other blade problems have been reported.
There were no injuries and no damage other than to the turbine itself, said Simons. The turbines are under warranty.
DTE Energy has shut down operating turbines and put construction on hold.
The utility is working with GE to investigate the malfunction. The project will reopen “as soon as a root cause is determined and we're confident the wind park can be operated safely,” said Simons.
The entire project was to have been completed by the end of this month.
