Faulty blade caused collapse: company

A single faulty blade is being blamed for a wind turbine collapse that occurred in Raleigh Township earlier this year.

The Raleigh Wind Power facility returned to service on March 28, according to TerraForm Power, which owns the wind farm.

“The review confirmed that the collapse of a turbine at the facility earlier this year was caused by a single faulty blade. No other similar issues were identified through the review process,” said Chad Reed, director of investor relations, in an e-mail on Monday.

He added the review was conducted by third-party professionals, as well as the company's own engineering team.

The turbine tower buckled in the early morning hours of Jan. 19. The entire 52-turbine facility was taken offline as a precaution until the inspection was complete. There were no injuries.

Reed added the company plans to keep a close eye on the facility in the meantime.

“We will continue to regularly and rigorously monitor all turbines as part of our ongoing review and maintenance process,” he said.

The incident prompted renewed calls by two area Progressive Conservative MPPs – Rick Nicholls and Monte McNaughton – for the Ontario government to impose a moratorium on further construction of other wind turbine projects in the region.

Ministry of the Environment and Climate Change staff said they weren't aware of similar occurrences in the area before.

In a previous interview, a spokesperson for the Canadian Wind Energy Association (CanWEA) indicated such failures are rare.

“As far as CanWEA is aware, this is the second time an incident of this kind has occurred in the history of the Canadian fleet of 6,400-plus wind turbines,” Jean-François Nolet said.

Wind turbines are regularly inspected and maintained to ensure peak performance and safety, he noted.
