MATTITUCK, NY — A wind turbine fire broke out at a North Fork winery recently, police said.
“Most failure incidents of wind turbine towers are due to a combination of factors, among which extreme wind is identified as the most common,” says a detailed study of 48 tower collapses between 2000 and 2016 soon to be published by academics from the engineering department at the University of Birmingham in the UK.
The latest incident follows the collapse in February of a GE turbine at the Casa Mesa Wind Energy Center in eastern New Mexico, which only entered commercial operation in the fourth quarter of last year. The US OEM said then that it would investigate what it believed to be “an isolated incident”.
A wind turbine at the Chisholm View wind farm near Hunter, Okla., collapsed Tuesday May 21, 2019. Enel Green Power North America, which owns the turbine, is working to determine why it fell. Access to the site was blocked for safety reasons as of Wednesday May 22, 2019.
The team at Heritage is working to determine the cause of the break and the next steps to take to repair it.
The fire destroyed the nacelle, which houses the main components of the turbine, as well as parts of the blades and tower. Strong winds also carried some debris out into nearby fields.
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.
The charred remains of the generator of the wind turbine that caught fire late Monday afternoon is clearly visible from the Elkton Road. Seley said there was nothing firefighters could do except watch flames consume the unit themselves. "It's way too high and you are not going to save anything," he said.
Firefighters and deputies were called after a wind turbine caught fire near the village of Elkton. Jeff Smith, an Elkton village official, said the fire, which broke out on April 1, is 300 feet in the air and crews cannot reach it to extinguish the blaze. The turbine is part of the Harvest II wind energy facility placed in service in November 2012 by Exelon and is one of 33 Vestas V-100 (1.8 MW) turbines erected in Oliver, Chandler and McKinley townships.
“Turbines are magnets for lightning which is why they are fitted with conductors to transfer the energy to the ground but they can cause significant damage. Blades can explode; generators and control system electronics can incinerate. “The repair of lightning damage can be dangerous and expensive.
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."
According to the wind turbine manufacturer, a lightning strike could have been the reason why the rotor blade broke loose.
Several roads were closed Monday morning after a wind turbine in the Hahnweiler / VG Baumholder wind farm experienced a blade failure.
Garner didn't speculate on what caused the wind turbine to fall over. However, other turbine mishaps that have occurred during high winds were because the turbine's braking system failed. Modern wind turbines are designed to shut off or slow their blades during high winds. If the blades turn too fast, it can cause the entire structure to become unstable and then disintegrate.
After sustaining damage from a fire last fall, the town’s second wind turbine is set to sit idle for the foreseeable future. Or it may be taken down by the operator, town manager Tony Marino told the select board this week. But the board also got unwelcome news when Marino told them the project was never bonded.
