Part of a blade on a wind turbine just off Grey County Road 8 southwest of Dundalk broke and fell to the earth last Wednesday morning.
LYFORD, Texas — A wind turbine caught fire in Lyford on Monday.
London-listed TRIG said that routine inspections had identified signs of stress fatigue on certain areas of the support structure of the helihoist on some of the 6MW wind turbines manufactured by GE. “Generation at the wind farm was paused as a precautionary safety measure whilst the root cause of the issue is being investigated,” TRIG said in a statement.
“I am not someone whose nerves get on edge very easily, but I didn’t want either myself or my people close to it. What I saw gave me fear,” said Wreath. “I left with many more concerns and questions than I had arrived with.” The 120-megawatt capacity project — located along the Oklahoma-Texas state line between Guymon and Hardesty — went operational in 2012 and contains 60 towers within Oklahoma. About nine towers show signs of catastrophic failure, where portions or entire blades are missing or nacelles at tower tops have burned. Dozens of other towers are locked down, either because of internal damage that can’t be observed without a detailed inspection or because of other problems that could be impacting their operations.
“An investigation has been launched into the cause of the incident and the best course of action going forward,” added a statement from Vattenfall. “So far, a 500 meter safety zone has been established around the mill, in which ships are not allowed to travel.”
Developers Vattenfall and Ørsted are analysing why Vestas’ V80-2.0MW turbine caught fire at the Danish wind farm. Vattenfall and Ørsted are investigating after a turbine at their co-owned 160MW Horns Rev 1 wind farm off Denmark caught fire.
JOHNSTON COUNTY, OKLAHOMA (KXII) - A wind farm turbine in Johnson County caught fire, after it was struck by lighting during Friday night’s storms.
Ada-Liberty Township Fire Department was called to a wind turbine fire reported at 4:31 a.m., Friday morning (March 26), according to the Ada police report.
Leading edge erosion on wind turbine blades is a major cause of reduced power output and efficiency as wind farms age. But, this growing problem is not well understood, so in today’s article we’ll tackle some of the root causes of leading edge erosion, what’s being done about it, and what we should look to in the future to solve this industry-wide problem.
At the end of November, a 230 meter high wind turbine near the town of Jörn in Skellefteå municipality collapsed. The whole tower gave way and crashed to the ground.
The turbine is part of the Harvest II Wind Project owned by Exelon Generation, the second part of a wind farm whose first phase began operations in 2008. Harvest II's second phase started operating in 2012. Turbine #7 is located south of Crown Road and east of Gagetown Road.
The cause of the accident is unknown and the company is assembling a team that will investigate at the site, spokesman Anders Riis said on Monday by phone. A lot of snow is expected this week, which may delay the work, he said. No one was injured in the incident. Sweden is turning to the most mature renewable energy source to replace old nuclear reactors.
It was at 9 pm on Saturday evening that the wind turbine gave way and fell to the ground. Pictures taken by Norran show how the tower folded a few meters above the ground and then the turbine housing, tower and blades crashed down. ...It is now Vestas that will carry out an investigation into the accident.
A part of the wind turbine prototype “Vertical Sky A 32” with vertical rotors crashed on the wind test field during gusts. One of the three rotor arms and the 54-meter long rotor blade were in the field. Nobody was injured in the accident.
Last month, Dundonnell was also hit by a fallen blade at one of its Vestas turbines, which brought production across the wind farm to a halt for a few days as the cause was investigated. Campbell says it is clear that the blade fell because bolts holding it to the hub became loose, but the question of why those bolts became loose is still under investigation.
A wind turbine manufacturer is investigating its turbines after a blade broke off in southeast Nebraska. A spokesperson for EDF Renewables says a turbine fault error occurred at turbine 89 of the Milligan 1 Wind Farm on Thursday morning.
MidAmerican Energy, has idled more than 40 wind turbines at Iowa wind farms after a 50 metre-long turbine blade broke off and fell into a field last week. ...“The turbine that had the blade failure last week is the same type of turbine that had a blade failure last month in Adair Countym” he said. “They also had the same type of lightning system in them that channels lightning from a strike near a wind turbine blade down into the ground safely.
The fire specialist says that because of a lack of reporting and transparency around wind farm blazes, it is difficult to know how far off current estimates (ranging from 1 in 2,000 turbines to 1 in 15,000 ) are from the true number of fires each year, while many figures are more than five years out of date.
MidAmerican Energy says it has idled nearly four-dozen electricity-generating wind turbines while workers check them for safety after blades broke off of two similar turbines over the past two months. Those blade failures follow a break earlier this year and one in 2019.
For a second time in two months, a wind turbine blade broke off in central Iowa. The latest incident happened Thursday near Paton, in Greene County.
