Vestas and developer EDP Renewables are investigating after the blade of a V150 4.2MW turbine at the 125MW Timber Road 4 project broke off. The project was commissioned earlier this year.
The damaged turbine was one of 30 Vestas V110 2.2 turbines at the Hog Creek Wind facility that is owned and operated by EDP REnewables. The project was placed in service at the end of 2017.
The turbine, which supplements electricity used by the sewage plant, lost a blade when lightning hit about 1:30 a.m. Saturday. A power surge penetrated the plant and might have affected some equipment in the building, City Manager James Hockaday said Monday.
FirstEnergy, the publicly traded utility based in Akron, pushed lawmakers at the end of 2012 to freeze energy efficiency standards, according to The Columbus Dispatch. The company previously has argued that mandates on utilities increase costs for consumers. Environmental groups and green-energy proponents don't like talk of tinkering with the standards.
"Vestas has concluded that the root cause of the failure of the initial blade was due to a wrinkle in the carbon fiber of the spar (the support structure of the blade)," the report reads. "This wrinkle caused damage to propagate to the point of failure after the blade experienced high loads for a low number of cycles."
For now, the Timber Road II Wind Farm in Paulding County is silent except for investigators trying to determine exactly why two blades from a single turbine were damaged on a windy afternoon April 24. So far, the high winds do not appear to have caused the damage.
Huge chunks of debris from a wind turbine are scattered across a field near Payne, Ohio. So far no one including its owner knows what happened. People passing by have been trying to figure out the cause.
According to a spokesman with EDP Renewables, the turbine, which is located near Payne, had two of its blades sheared early Tuesday afternoon. Representatives from EDP Renewables have closed the site.
Around 12:45 Tuesday afternoon, two blades on a turbine were damaged so severely that debris was sent raining down on the field below. ...The owners, EDP Renewables, say while the investigation into what damaged the blades is ongoing, at this point it doesn't appear that strong winds were a factor.
Lightning struck the turbine shortly after midnight, pelting trucks parked below the machine with debris, according to various reports. Wastewater plant personnel successfully shut down the turbine a few hours later, safety personnel said. ...The 400-kilowatt turbine is the second of two erected by NexGen, which became operational in early 2010.
Inspectors will be out Tuesday afternoon to determine an official cause. Little believes a crack in the metal 120 feet in the air, mixed with the high winds caused the crash and $30,000 dollars in damage.
For the time being, while the cause of Sunday's collapse is being investigated, the district's other turbines will remain shut down as well as a precaution.
The piece of the turbine that fell was one of three installed at the school back in 2009. The company that makes the equipment is out of Scotland, they work with an Indiana company.
This was the second time in two years the school district had a wind turbine fail due to a problem with blades. The turbine that failed this week was not the one that had earlier problems, officials said. "At this point we're going to take a step back, find out what happened and make decisions from there," Perkins school Superintendent Jim Gunner said.
For the second time in two years, Perkins Schools officials shut down the wind turbines on school property after a mechanical failure.
A wind turbine installed at Shoreway Shopping Center last month did fine until it was pitted against an untamed energy source - lightning. One blade of the 100-kilowatt turbine, atop a 120-foot tower in the Shoreway Shopping Center parking lot, was hit by lightning during a thunderstorm Wednesday night.
The 100-kilowatt wind turbine installed two and a half weeks ago at the Shoreway Shopping Center to provide power for Apples supermarket is being repaired today. "Apparently, it got struck by lightning."
Kent Houston, Conneaut Area City Schools' superintendent, said he recently spoke with NexGen Energy, the Colorado company that built the 600 kW generator earlier this year, for a status update. A part has kept the mammoth machine from cranking out power at levels it was designed to reach, Houston said.
When students pull into the Perkins High School parking lot today, they'll see three wind turbines in front of them, fully assembled for the first time since February. But the blades aren't turning yet, and Perkins Schools superintendent Jim Gunner said the school will proceed cautiously in getting the system back up to full capacity. The original 6-meter blades, some of which blew off during an especially windy day in February, are gone.
New blades will be installed on four turbines that were shut down temporarily at two locations in the area. A crew yesterday replaced the blades on the wind turbine at Turtle Plastics in Lorain. New blades also will be placed on three turbines at Perkins High School in Perkins Township. The four turbines were built by the same company and were shut down to ensure safety after the blades broke off a turbine at Perkins High School.
