The designer of an experimental wind turbine located near Medicine Hat College says an operational decision to lock them from spinning led to one shearing off in high wind on Sunday night. As well, the working relationship between the college and company appears to have ended.
Jon Clifford, operations manager for WPD Canada — the company that oversees the operations of the Sumac Ridge turbine project near Pontypool — says he suspects replacement of the wind turbine blade that failed last spring will happen the first week of November.
Residents living near the Sumac Ridge Wind Farm say a damaged blade isn’t the only thing that’s been left blowing in the wind. The are fed up with the dangling piece of metal hitting the turbine and making a loud banging noise for the past two weeks. They are calling on the owners to repair it immediately saying it’s causing headaches and keeping then up at night.
A 5,400-kilogram blade on a wind turbine exploded and shredded near Pontypool in the City of Kawartha Lakes on Saturday morning. Officials are investigating after a wind turbine in the City of Kawartha Lakes was heavily damaged on the weekend.
KAWARTHA LAKES-Neighbours of the Sumac Ridge Wind farm on Wild Turkey Road say they heard a grinding sound followed by a loud explosion this morning. When they looked out they saw one of the blades on a turbine was shredded.
With large chunks of burning nacelle components and melting fibreglass blades falling from 80 metres above, there wasn’t much the West Pubnico Fire Department could do when a wind turbine fire was reported the afternoon of March 15.
Firefighters were at the scene quickly but could do little to battle the flames, West Pubnico fire Chief Gordon Amiro said. When the blades turn, the tips are more than 100 metres in the air — too high to fight the fire from the ground.
Firefighters were unable to get close enough to put the fire out directly because of the turbine's height and movement of the blades -- and it couldn't be turned off with the gearbox on fire. "It was too dangerous to get close to it," Amiro said. "Because of the length of the blades and the blades were turning, you didn't know where they were going to go when they fell."
"We couldn't get nowhere near because the blades was still turning, so, and pieces was breaking off the blades," he said. "So if a piece was to fall off, it would go a long ways with the wind and that. So it wasn't safe to go nowhere near the tower at all."
The city is dismantling a series of recently-erected 10-metre-high wind turbines along the Lake Ontario shoreline amid fears they could fall on beachgoers.
A Huron Wind Vestas V80 1.8MW turbine was damaged by high winds off Lake Huron north of Tiverton on May 4, 2018. A worker at a neighbouring facility captured the image of the tip of the turbine blade broken and dangling from the structure.
A single faulty blade is being blamed for a wind turbine collapse that occurred in Raleigh Township earlier this year.
TerraForm Power said 22 of its 52 turbines are back online
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 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.
WindShare's own blog about the Exhibition Place turbine shows it has been plagued with problems over the past five years. The issues began after the turbine's main bearing was replaced in 2011. ...A series of what the operators called "cascading faults" took the turbine off line from the summer of 2012 until March 2013.
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.
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.
