"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.
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.
One week after an 80-metre wind turbine collapsed in Cape Breton, there is still no clear indication of what caused what's believed to be the first catastrophic failure of its kind in Canada.
Enercon said the incident occurred on 17 August during a "scheduled component exchange".
One of the wind turbines at Ferndale has been tethered after it was found to be leaning
When D’Eon, who lives near the Pubnico Point Wind Farm, came outside to investigate what he heard, he saw that one of the blades on a turbine was “in distress.”
NextEra Energy acknowledged Wednesday that it shut down some of its Ontario turbines and warned landowners after it was discovered a part on spinning blades could fly off. NextEra said the potential problem was with "a small thin plastic attachment" on the turbine blades that could separate while in operation.
Jodie Bird, another NextEra spokesperson, recently spoke with the Sarnia Observer said one of the turbine's 50-meter-long blades "snapped" during a storm, and Bird initially suggested lightning might be to blame for the damage.
Lightning is the likely culprit after a wind turbine blade snapped amid a storm late Sunday into early Monday, near Grand Bend, a NextEra spokesperson says. One of the towering turbine's three 50-meter-long blades was dangling Tuesday.
An anti-wind turbine group was circulating a photo of a turbine in the Grand Bend area, possibly damaged by Sunday’s severe thunderstorms.
An investigation into a damaged wind turbine blade at the Eastern Kings Wind Farm is still underway, says head of external communications for the company who makes the turbines.
“It was shut down due to safety concerns because of blades starting to wear, There were a lot of high winds with (tropical storm) Arthur. It was shortly after Arthur that we noticed that there was some damage.”
André Minville, director of Murdochville fire service received the call to 1:10 p.m. Wednesday: blazing wind park at Copper Mountain. Mr. Minville and firefighters joined the company technicians NextEra Energy on site. They set up a perimeter and waited for the fire to calm. Nobody was injured. The fire destroyed a blade and the nacelle (central portion of the wind turbine, which contains the generator).
An early morning fire on April 2nd destroyed the top portion of the seven-year-old turbine. The fire burned itself out in about two hours, and while fire crews attended the scene there was little they could do about a blaze 80 metres up in the air.
Dan Morgan “saw an orange fireball a couple of miles from the front yard, so I thought I better investigate this,” before driving over to get a closer look. The Goderich Fire Department was called to the scene, but with the blaze 100 metres in the air, there was little that could be done.
During the early years of the North American Wind Industry, the general misconception regarding blade maintenance was that once the blades were in the air, routine maintenance was not required. As the industry matured, some tough lessons were learned. Maintenance, especially on the leading edge of the blade, is not only recommended but essential if blades are to reach their design life expectancy.
