Reeves said when Smithfield and Morrisville fire departments arrived at the scene, it was determined the generator housing was ablaze, sending flames up the tip of one of the blades. The departments determined letting it safely burn down was the best course of action.
The replacement program follows blade failure on Nov. 17, 2013, at the wind farm’s 34th tower, near Centerline Road and Route 20A. The blade fell to the ground at the base of the turbine ...An analysis revealed the break was caused by a spar cap issue. A spar cap is located on both sides of the blade. It essentially gives the blade strength, and is made from composite materials.
“GE has identified a discrete set of blades that could have been subject to this anomaly and we are working with potentially affected customers to help ensure the reliability of our turbines and their safe operation,” the statement read.

“Out of caution, all turbine commissioning and turbine operations at the wind farm have been suspended,” Invenergy says. “We are working with GE, the turbine manufacturer, to determine the cause of this incident. Following a GE blade break on Nov. 7, utility DTE Energy has also ceased work on its 112 MW Echo Wind Park in Michigan. Scott Simons, a DTE Energy spokesperson, recently told NAW that GE was performing a reliability test on a turbine when the blade fell.
The turbine’s commissioning had begun Wednesday and the unit was operating at the time, Invenergy officials said in a statement. “Out of caution, all turbine commissioning and turbine operations at the wind farm have been suspended,” the statement reads.
Gay's home in Varysburg is surrounded by wind turbines - 58 of them. The General Electric 1.6 megawatt turbines were recently installed by Invenergy at the Orangeville Wind Farm. Each individual blade is 160 feet long and weighs 200,000 pounds.
The site manager at the facility said the incident took place while the turbines were being tested. The broken turbine is one of 58 at the wind farm that were installed last month. “They just put them up I thought they were new they should last a couple of years” said Weigel.
Invenergy's Orangeville Wind Farm (formerly known as the Stony Creek Wind project) experienced a catastrophic blade break. The project, which is still under construction includes 58 GE 1.6-100 wind turbines (94 megawatts). The turbines are scheduled for commission the second week of December 2013. Witnesses at the site told WindAction that blade debris flew past the 511-foot safety zone set by the town for participating landowners, 700 feet from property lines for non-participating neighbors, and 1100 feet from non-participating neighbors' structures/residences. The setback distances were requested by Eric Miller of Invenergy to get more turbines in a smaller area.
Recently there have been several units shut down while 10 blades were repaired. If each came from a different turbine it would mean the wind farm was producing 10% less electricity than planned while the turbines were out of service. It could also support the contention that the life of wind farms will be less than planned.
In 11 letters sent to Ridgeline Energy - which has proposed 492-feet high wind turbines in the area - the administration warns that the structures would exceed height standards unless they were reduced to between 85 feet and 175 feet depending on the location.
The FAA says the structures would present a hazard to air traffic safety. Ridgeline Energy wants to build industrial wind turbines that are 492-feet tall and has filed 11 proposals for them with the FAA.
Noble Environmental Power brought in a basket crane recently to get a closer look at the damage caused to a wind turbine in Altona Wind Park on Jan. 29. "What they were able to see when they were up there was limited," said John Bahouth, Noble's vice president of human resources and communications.
Turbines at Noble Environmental's Bliss wind energy facility in New York were found leaking oil from the nacelle. NY's Department of Environmental Conservation has been called to investigate.
Flames were consuming the top portion of a wind turbine behind the Rand Hill Dairy Farm, which is across the street from their house. "The fire caught one of the blades and made it look like a Roman candle," Phil said. "There was a snow squall that night, but we could see the flames burning right through it."
A GE wind turbine owned and operated by Noble Environmental caught fire in high wind conditions. Firefighters were not equipped to address the fire. The cause of the fire is unknown.
On January 16 (2012) a transformer failed at a wind turbine located in Wethersfield NY. The turbine is owned by Noble Environmental. Scorch marks appear far above the vehicles on the ground. State workers are investigating the fire and overseeing the oil spill cleanup caused by the failure.
"The wind got so bad up there and it's been spinning so fast, it's scary. It looks like it's going to take off at any moment," said Mary C. Grogan, a neighbor who has protested the turbine since it was erected in 2009. "It has never run before. This is the first time it has operated."
Iberdrola Renewables resumed construction on some turbines on the Hardscrabble Wind Farm Friday after test results showed some foundations were safe, company spokesman Paul Copleman said.
"The prospect of a large wind turbine in the general vicinity of the Indian River High School does cause concern for our operations, most notably through potentially significant adverse impacts to both approach procedures and radar coverage at Wheeler-Sack Army Airfield," Fort Drum spokeswoman Julie A. Cupernall said in an e-mail.
