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.
Tim Jolly is a fifth-generation McLean County farmer and is looking forward to a safe harvest this fall. However, while farming in the footprint of a wind farm near Lexington, Jolly has major concerns over the potential of falling debris from nearby wind farm turbines from the Bright Stalk Wind Farm.
Adair County farmer Curt Beane said the blade crushed the corn below, but nobody was injured. “I work in the field that it came down, and I do have true safety concern,” Beane said. Beane said he does not own the land that the blade fell onto, but he does farm it.
MidAmerican's Arbor Hill wind energy facility suffered a failure when a portion of a 177-foot long blade broke off the turbine and was flung onto another farmer's property. A similar blade break occurred at a month later at the Beaver Creek wind farm, also owned and operated by MidAmerican. Both the Arbor Hill and Beaver Creek facilities have Vestas V110 2.0 MW turbines installed.
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.
It started Monday afternoon and was still considered active Friday morning, according to the Sweetwater Fire Chief Grant Madden. ...The wildfire continued to run for at least five miles and has burned more than 3,200 acres destroying land in its path.
BRADY — Multiple wildfires have scorched thousands of acres across the Concho Valley in the past three days fueled by dry brush and temperatures reaching above 100 degrees.
SWEETWATER, TX — A wind turbine in Nolan County sparked a wildfire Monday just north of FM 89 near the county line.
NOLAN COUNTY, Texas — Firefighters battled a wildfire in Nolan County. Sweetwater Fire Chief said the Game Ranch Fire, located just north of FM 89 near the Nolan/Taylor County line, was sparked by a wind turbine. As of Monday evening, the fire had burned 1,500 acres, and was 30-percent contained. The Texas A&M Forest Service is working with Sweetwater FD, Lake Sweetwater VFD, Mulberry Canyon VFD and Nolan County VFD to put out the fire.
The company submitted records to the county showing the agreements have been reached. Levy said the agreements have been executed and the company would e-mail copies of them to the county. In cases where NextEra could not reach agreements with landowners, the company curtailed operations of turbines close to the county residents’ homes so the machines are within the acceptable noise and shadow flicker limits.
I asked Steve Peters if he knew exactly when the blades in the next section south broke. Peters recalled that, "the blade broke during the morning hours of Dec. 30. Nothing looked wrong at that site until before noon. Steve also said he had heard that 32 turbine sites (96 blades) had blades that needed to be repaired or replaced.
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.
Sibley Fire Chief Kenny Huls says when they were looking for what may have caused the fire, they noticed some charring on the windmill motor, and with the distance and the wind carrying those sparks, he says it appeared to him that perhaps the wind turbine malfunctioned and shot a spray of sparks out into the field.
“I could smell an electrical type smell for a good while, and my mom smelled it too,” Gregory resident Dolores Moreno said. “I was looking at our own house going room to room thinking it was coming from our home since the smell was pretty strong. A while later I heard the sirens so I knew it wasn’t us.” She also said that she heard someone saying that just before the blaze, they could hear a noise coming from the turbine.
Local officials say that they have no choice but to let the fire burn itself out. They are currently trying to figure out who the wind turbine belongs to so they can contact them to turn off the electricity. The area is being kept clear in case any debris falls off.
One of the 47 Siemens G132-3.465 MW turbines operating at Apex Clean Energy's Midway Wind facility in Texas exploded into flames. The turbines stand 495 feet tall and were placed in service at the end of 2018. The burning turbine is located between Gregory, TX and Taft, TX near Corpus Christi.
The blade broke on one of the wind turbines on Pine Hill Road in the Town of Cohocton. No one witnessed the blade fall, and no one was injured. Town Supervisor Judy Hall said there are three turbines in that area of Pine Hill Road, with three homes in the vicinity as well.
The narrow half of one of the three blades fell to the earth. Hall said it was her understanding that some debris ended up in a nearby wooded area. She said talks with a former wind company employee indicated the blade was likely spinning at the time of the failure.
The sudden collapse of a wind turbine in a densely populated New York City neighborhood has alarmed state and city officials, who are promising investigations and new legislation in response to the accident.
