A wind turbine manufacturer is investigating its turbines after a blade broke off in southeast Nebraska. A spokesperson for EDF Renewables says a turbine fault error occurred at turbine 89 of the Milligan 1 Wind Farm on Thursday morning.
GE Renewable Energy has identified and addressed the root causes of the two turbine failures earlier this year. The May incident is understood to be down to an issue experienced during a turbine reboot addressed with a software update. The earlier collapse at the Casa Mesa Wind Energy Center is being attributed to a fuse-related blade issue while the turbine was running in overspeed mode during high winds.
Upstream Wind Energy tower 57, located northeast of Neligh, lay crumpled on the ground like a deflated air dancer Friday morning.
NextEra Energy, owner of the Steele Flats wind farm in southern Nebraska, has suffered at least four wind turbine calamities in recent weeks, including broken blades, a fire and a collapse.
News reports indicate wind turbines collapse regularly in the U.S. and elsewhere. One county in eastern Michigan had two topple in one week last year. ...Ethan Thorp, 27, of Steele City, went out to see the downed wind turbine near Diller ...he's grateful the tower and turbine came down in the cornfield during the early morning hours. "You’d hate to be out there spraying" in the field if a turbine collapsed.
BEATRICE – One of the wind turbine towers in the Steele Flats Wind Farm near Diller, has collapsed. The tower is a half-mile west of Nebraska Highway 103 and one mile north of Nebraska Highway 8. The tower is part of the $138 million wind farm, developed by Florida-based NextEra Energy Resources, which includes 32 wind turbines in southeast Jefferson County and 12 more in southwest Gage County.
Kallhoff said he was out in his yard working when he heard a loud noise come from the south. When he looked up, he saw pieces of a wind turbine blade falling to the ground from a wind tower located just over a mile from his house. It marks the second time in less than two weeks that there has been a structural failure on a wind turbine blade.
Winds were strong in the area that day, and wind farm owner Invenergy said the blade at Prairie Breeze unit #51 experienced a structural failure.
Edison Mission Energy and Vestas still was working at week's end to get the plant, which has 22 wind turbines, back online. ...In late 2008, an explosion and fire in a turbine injured three workers during construction of the nearby Elkhorn Ridge wind farm, also owned by Edison Mission Energy.
The turbine sustained damage when it was struck by lightning in May. Initial inspections revealed a split on the outer tip of one blade that was less than 24 inches long. The split was repaired by LES and Vestas (the turbine's manufacturer with which LES has a service agreement) at an estimated cost of $45,000.
The Bloomfield Fire Department responded to the emergency call, but the small fire burned itself out. In late 2008, an explosion and fire in a turbine injured three workers during construction of the Elkhorn Ridge wind farm in northeast Nebraska.
An investigation suggests an explosion and fire inside a Nebraska wind turbine was caused by a "foreign object". ...the "object" blew into the turbine causing the blast.
SPRINGVIEW, Neb. - In this ranching village near the South Dakota border, there's a Turbine Avenue and a Turbine Mart convenience store and the annual Wind Turbine Days festival. But soon the two wind turbines that inspired those names - the first in Nebraska when they were erected in 1998 - may be coming down. Frequent breakdowns and increasingly expensive repairs are dooming the graceful structures.
