After the plane struck the wire, the cable wrapped around power lines, prompting Xcel to temporarily shut off power to the wind turbines. While crews repair the damage, federal investigators will work to piece together what led up to the crash that claimed the life of a veteran pilot, once honored by the FAA for his safe flying record.
The blades of a wind generator at the University of Minnesota Duluth’s field research station just north of Duluth spun out of control on Friday afternoon, for a time prompting concerns from law enforcement officials.
Crow Wing Power of Brainerd was negligent in its response to a northern Minnesota farm family’s concerns about stray voltage on their property, a Cass County jury ruled Friday. The jury awarded Randy and Peggy Norman $4.8 million in economic loss damages and $1.5 million in nuisance damages for a total of $6.3 million, the largest amount ever awarded in a stray voltage case in state history, according to the Normans’ attorneys.
Technicians with Vestas offered two options – repair the pitted bearing for about $65,000 or replace the entire generator with new shafts and bearings for about $175,000.
Wind farm technicians and officials with EDF Renewable Energy believe one wind tower, just northeast of Dexter, was struck by lightning on April 24, which mangled one of the structure's 37-meter, 14,000-pound blades.
Tina Sapp works at Nino's Bakery right on Main St. and said she watched it all happen. She said she immediately feared for her own safety. "As soon as it fell, we were like, 'What if it rolls this way?' That's all we kept thinking," she said.
"We're seeing some steel quality issues in the gearboxes that we have. They're just not holding up as long as they should." Of the 67 General Electric 1.5 megawatt turbines near Dexter, 46 were classified as follows: • 32 were dubbed "unusual/monitor." • 12 were noted "abnormal/repair expected eventually." • Two were called "abnormal/repair required."
Lightning hit one of the blades of the turbine, sending part of it to the ground. The fire continued to burn, both at the base and at the top of the 175-foot-tall tower. Ultimately, all three blades were destroyed.
The Shakopee Mdewakanton Dakota Community wind turbine will undergo major maintenance in the next few months. Until that time, it will remain offline until a warranty repair is complete to install a new generator, the Prior Lake tribe said.
While capturing wind energy with Suzlon's giant wind turbine blades didn't pollute, the manufacturer of the equipment did, according to a consent agreement between Suzlon and the MPCA that was filed in Pipestone County District Court. The agreement detailed violations involving air quality, hazardous waste, solid waste and the handling of storm water runoff.
Sommers says the storm damaged other nearby turbines as well. Some are missing blades. On others, strong winds tore from the top of the tower the hood that protects the turbine and electronic equipment housed inside.
The technician suffered third-degree burns in the accident at the Iberdrola Streator Cayuga Ridge South Wind Farm near Odell, Ill. An investigation by OSHA found Outland didn't ensure technicians placed locks and tags on ground-level switches. A worker flipped a switch, energizing a transformer while the technician was working 350 feet above.
Two workers were injured this morning while constructing a tower for a wind turbine on a private property in rural southwest Rochester, according to the Rochester Fire Department. The two were evacuated from the accident by medical helicopter.
Safety was the main theme of a meeting Thursday for landowners involved in the Bent Tree Wind Farm project. For instance, even though some work will be done on landowners' private property, they aren't allowed on the construction site. If they call ahead and ask they may be allowed to see some parts. "This is your land and we respect that," said Bent Tree construction manager Tim Shugart.
With their organic gardens and ample land, Andy and Jessie Welsh had the perfect plan. Living in rural Stearns County, the young couple had hoped to be energy self-sufficient and green. ...From the start, the installation was delayed and marked by setbacks. Electricians had a hard time getting the turbine wired to run properly. When it finally did, the turbine ran for just a few days before they received a call from the company instructing them to shut it down.
He said that people don't realize that a wind farm is constant maintenance, and to ensure longevity, preventative maintenance is needed. ..."Wind energy is not the complete answer to our energy needs," McNeilus said. "It is a piece of the pie, but you still have to have the whole pie, because there are days when the wind doesn't blow."
A small plane crashed a year ago near Grand Meadow, killing the pilot, because it didn't have the proper flight instruments for flying in that day's poor weather, a federal agency says. The pilot's failure to maintain control of the airplane while maneuvering around a wind farm at a low altitude also was a factor.
A 33-year-old man is recovering from a severe electric burn he sustained Tuesday afternoon while working on a wind turbine north of Dexter ...Officials believe the turbine was electrically charged when Chlan was working on it, giving the worker an electrical burn on his left arm, Amazi said.
A wind farm worker is okay following a crane accident Sunday morning. A Winnebago County Sheriff's report confirms Billy Cody was trapped in a crane at the construction site located between Forest City and Thompson.
When it came time to start repairing a wind turbine at the ethanol plant on Oct. 15, the project had to be put on hold. ..."The blade has been cracked all summer. It's been frustrating," says Dan Moore, director of project development for Renewable Energy Solutions. When the broken blade was discovered, the turbine furthest from the ethanol plant had to be shut down. All three blades needed to be replaced, says Moore, because we couldn't find one to match the other two.
