Conlan Kennedy, NextEra communication specialist, said the turbine was damaged the night of April 16. Members of a NextEra wind technician team said there was a big storm in the area that night and the team was investigating the possibility of a lightning strike but the cause is still under investigation, Kennedy said.
With the wind turbine standing over 400 feet tall, crews said the fire was impossible to reach. Sylvan Grove Fire Chief Marc Lovin says there isn't anything his firefighters can do but let the turbine burn.
There is security video and it showed the turbine working normally one minute then falling over the next, Newhold said.
The U.S. Department of Labor has opened a second investigation at a Pratt County wind farm after two workers were injured in separate incidents in less than a week. The latest incident happened Wednesday night after a 4-pound bolt fell and struck Blattner Energy employee Gary Newman on the head – knocking him unconscious. ...NextEra Energy Resources contracted with Blattner Energy to be the general contractor for the construction site.
On arrival, deputies were told one of the workers had fallen about 126 feet from the turbine and landed on his back in the mud below. ...Another worker was trapped for about 30 minutes, hanging by his safety harness.
"At this time, there is no threat to residents around the project, but we ask that all keep a safe distance from the affected turbine so that our safety personnel may conduct assessments and take any required actions as safely and quickly as possible."
It's unclear what caused a wind turbine in Haskell County to collapse on Monday, but the owner of the Buffalo Dunes wind farm says an investigation is underway. ...Completed last December, Buffalo Dunes 250-megawatt wind farm includes 135 GE wind turbines spread over 40,000 acres of land.
Disappointment and frustration, that’s how city commissioners describe the challenge of what was supposed to be a money-saver for citizens of El Dorado. Instead, commissioners say its been a series of trial and error trying to get it to work consistently.
Wind energy turbine farms could be hazardous for small aircraft. That’s the conclusion of a study done by the University of Kansas for the Kansas Department of Transportation. “These turbines can set up a circular vortex that can roll a plane if it gets in there,” said Tom Mulinazzi, a KU professor of civil, environmental and architectural engineering.
Current Federal Aviation Administration guidelines only evaluate vertical structures from a static perspective within an airport zone. However, wind farms are dynamic with spinning blades that can create rotational vortices. "This research points out a shortcoming in the current evaluation process and that is why this is so important.”
"There was a mechanical failure that caused the trailer to go into the median," Cordry said. "Everything was totaled. The truck rolled over; the trailers were damaged and so was the load."
lanning and Development Director Nancy Scott said that is not the case and that the city regulates their placement only in the interest of public safety and to protect neighbors from nuisances such as noise or shadow flicker caused by spinning blades catching the sunlight. In Myers' case, Scott said, the city was responding to a complaint by another citizen and Myers' first problem was that he never submitted plans for the city's approval or sought a required conditional use permit.
Siemens Energy officials ordered wind turbines using its B53 rotor blade - manufactured at its Fort Madison, Iowa, plant - to run at significantly reduced speeds while the company works to determine what caused two blades to fall from turbines at two wind farms in recent weeks.
An inspection of the damage was performed on Wednesday confirming a lightning strike. Results of the inspection show the damage does not appear to be extensive.
"There was a cold front that came through two weeks ago," said Kurt Bookout, public utilities director. "During the night we had the wind switch from 35 to 45 out of the south to 50 to 60 out of the north in the middle of the night." As the wind turbine was turning into the wind the blade tips deployed and flaired out as a braking mechanism. That caused one of the tips to break.
Five turbines were also destroyed at a nearby wind farm that's still under construction. The preliminary rating of the tornado northwest of Harper is an EF-3. Officials say that tornado damaged a farmstead four miles west of Harper. The maximum width of the tornado was 200 yards.
All lanes of US-56 highway from the K-31 junction in Osage County to the K-99 junction in Lyon County will be closed between 9 a.m. and 3 p.m. Thursday and Friday so crews can remove from a ditch an overturned semi-trailer that was hauling a wind turbine tower.
Three wind turbines that power the heating, ventilation and air-conditioning system at Cloud County Community College's Concordia campus are casting shadows that are too long.
“Itinerant pilots unfamiliar with the tower array will be at greatest risk, in marginal VFR visibilities. Those pilots may be entering the array before they visually detect it. The entire outer boundary of the array will not be visible from any given point during marginal VFR conditions because the proposed tower array covers approximately 16 square miles within the 8-mile radius,” according to the letter.
All of them were later found to have damaged blade tips. Siemens alleges this occurred when they hit a rail overpass at Kansas Avenue and First Street in Kansas City, Kan. Siemens is seeking $3.2 million.
