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.
Lake Land College has removed two wind turbines after they suffered enough damage to render them inoperable. "The situation with the two 100 kW wind turbines is a snapshot of renewable energy in the United States in 2017," said Joseph Tillman, the division chair and Lake Land College's renewable energy instructor and coordinator. Wind is going to be around for a while, but other forms of renewable (energy) are gaining in use.
A wind energy conversion turbine caught fire Friday afternoon, causing responses from both Saunemin and Pontiac fire departments. ...It is, however, a little ironic that the source of power the turbines were trying to capture may have also caused or exacerbated the fire at the turbine.
A wind turbine in northern Livingston County caught fire Friday. ...Streator Cayuga Ridge began operating in March 2010.
Heavy black smoke and flames billowed out of the gearbox, rotor shaft and brake assembly case of the horizontal axis wind turbine (W7). Most of one flaming propeller fell to the ground.
A wind turbine near Emington burned Sunday afternoon, bringing attention from people for miles.
"On approach, we could see a lot of heavy smoke coming from the turbine," said Manchester. "As we got closer, we were able to see there was quite a bit of flame coming from the top portion of the turbine where the blades attach.
Driving down a county road in Henry County, Illinois, it’s not hard to spot the wind turbine with a broken blade. There are hundreds of turbines in the area but only one with two blades instead of three.
Only one 159-foot-long blade remains attached to turbine No. 134 on Thursday in the California Ridge Wind Farm north of Oakwood. Owner Invenergy's initial investigation found that severe weather caused one of the other two blades to break off and fall to the base Nov. 20, taking another down on its way.
General Electric said it is doing “thorough investigations” of three recent incidents involving GE wind turbines breaking in the U.S. — including one at the California Ridge Wind Farm in Vermilion County — and has identified “a suspect population of roughly 1.5 percent of our total blades in our wind turbine fleet.”
For the third time in 17 months, a wind turbine blade manufactured by General Electric has broken off at an East Central Illinois wind farm. The latest incident occurred about 9 p.m. Nov. 20 in Vermilion County at the California Ridge Wind Farm operated by Chicago-based Invenergy. Another turbine blade broke in that same wind farm in November 2012, following a June 2012 blade break at the Settlers Trail Wind Farm near Sheldon.
Early this morning, there was a wind turbine failure at the California Ridge Wind Farm just north of Oakwood, Illinois near the Newtown Middle School location.
The blade of a wind turbine in the Settlers Trail Wind Farm near Sheldon was damaged over the weekend. E.On Climate & Renewables North America, Chicago, is investigating how the damage occurred.
An "isolated manufacturing issue" caused two wind turbines in East Central Illinois to break last year, the manufacturer of the towers said Monday.
In light of recent turbine damage in Vermillion and Champaign counties, Livingston County officials have raised concerns regarding the wind farm in their county. Last week, a blade broke at the recently built California Ridge Wind Farm in Vermillion and Champaign counties. The turbine is near Route 49 and Vermillion County Road 2700 North, a few miles southwest of Potomac and south of Armstrong.
The firm that operates the recently built California Ridge Wind Farm in Vermilion and Champaign counties said it is looking into how a wind turbine's blade broke on Tuesday night. Chicago-based Invenergy LLC released a statement Wednesday, saying that one of the wind farm's 134 turbines "experienced a broken blade last night" but how the damage occurred was not immediately known.
"One of the blades looks like it has peeled back and wilted over, and there is debris lying around the base of the turbine," the witness said in the email. "Part of the blade that came down is laying a distance away from the base in the field."
Stengel said broken blades occur occasionally with one happening in May 2010. The blade was removed in the last 1½ weeks. It shattered in mid-March.
Ellsworth came from Germany to live in rural Marseilles 17 years ago with her husband, who is from Morris. She researched the operating record of towers, primarily in Germany, where she said they have much longer experience. As a result of this experience, she said Germans never erect wind towers any closer to a home than one mile. "Blades can tear off and be like missiles," she said.
Miner said crews are examining the two towers to see if there is any damage to other components. At any rate, a crane will be brought in and the blades replaced. The replacement process will take at least a few weeks. About one year ago, another blade broke in the same area. In that case, high wind caused the damage.
