Vern Martin, a mechanical engineer and vice-president of Flowcare Engineering consulting company in Cambridge, Ont., believes a blade may have malfunctioned and struck the column, causing it to buckle. "That ... has actually been recorded as occurring before in some of these other failures," explained Martin.
A company in Chatham-Kent, Ont. has shut down all 51 of its wind turbines as a precaution until an investigation reveals what caused one of the turbines to collapse last Friday. The turbine in Raleigh Township, near the corner of Drake Road and the 16th Line, collapsed on itself.
The turbine that collapsed was a GE 1.5MW xle, placed in service in 2011 by US-based Invenergy as part of the 52-turbine (78 MW) Raleigh wind facility in Chatham-Kent in southwest Ontario. The project was sold to Terraform in 2015. No information has been released as to the cause of the failure.
The toppled turbine was discovered by a hunter scouting for coyotes early this morning in Harwich Township, according to The Blenheim News Tribune. The huge turbine blades and motor assembly crashed to the ground and the support structure appear to be folded in half.
No injuries were reported after a wind turbine in South Kent collapsed early this morning, causing a huge outcry of concern from the public on social media.

Jakubec says this discovery is just the tip of the iceberg and wonders how many other wind farms are improperly built. He says this might be one of the biggest water scandals since the Walkerton tragedy in 2000 when seven people died after their water supply was contaminated.
If you're afraid of heights, then clinging to the side of an 80-metre wind turbine tower is likely not the job for you.
Enercon's email did not elaborate on the hub's damage. However, documents from the Labour Department regarding a subsequent stop-work order said a hub assembly was damaged in a "bearing failure" in March 2016. On Aug. 17, workers tested the turbine's lightning-protection system, which required positioning the blades so they pitched into the wind.
RCMP discovered several bullet holes in one of the transformers for the wind turbines. They say it appears the shots were possibly fired from the nearby roadway.
Lotta Schmidt said “a combination of factors” led to the collapse, but despite being asked several times to specify what those factors were she declined to elaborate. “The fact that it’s not a design or a technical issue allows us to be confident that it’s not something that can happen at other sites.
"If it's too windy, then maybe it's not the right place for it [the turbine]," said Doreen Aucoin. "Because it is close to houses and I imagine the people up the hill ... they must have been scared because it was right near to their house."
The province’s energy minister says setback regulations are in place to protect the public and neighbouring landowners should wind turbines fall, as has happened twice in Cape Breton in the past five months.
It’s shattered it to pieces, blown apart by a south easterly wind, it was blown to pieces — incredible power. -- Pierre Chiasson
People in the Grand Étang area of Nova Scotia's Inverness County tweeted photos and video of a wind turbine, whose main trunk was snapped clean in two, with the leftover blade apparatus lying at its base.
The Environmental Review Tribunal has stalled a wind turbine project, ruling it would cause harm to both human health and the environment.
Ontario’s Liberal government denies Opposition charges that it interfered with the witness list for a hearing into a plan to install at least six, 152-metre-high wind turbines near the Collingwood airport.
Wednesday afternoon, flat-bed trucks were seen entering the wind farm to retrieve shipping containers used to transport equipment and tools to the site. There is no timeline for when the investigation will be complete.
Two investigations has been launched into the collapse of an 80-metre wind turbine in Cape Breton, believed to be the first catastrophic failure of its kind in Canada.
