Turbine parts fly off blades

Turbine-debris-1_thumb All 19 turbines at a windfarm in the Scottish Borders were shut down after part of a blade was found lying by the roadside. This fiberglass component from the blade was found along with other similar components. An investigation is underway but it is believed the components were torn from the turbine(s) under high wind conditions.

NOAA Letter regarding NEXRAD impacts

Noaa_response_to_sen_fischer_cottonwood_wf_signed___5jan15_thumb Kathryn D. Sullivan Ph.D., Undersecretary of Commerce for Oceans and Atmosphere, sent this response to Nebraska Senator Deb Fischer after Senator Fischer contacted NOAA with concerns pertaining to NextEra's proposed Cottonwood wind energy facility which would site dozens of wind turbines within 2-7 miles of the NEXRAD weather radar in Blue Hill, Nebraska. Senator Fischer's constituents contacted her out of concern for their safety if the weather radar was impaired by the turbines. The letter sent by Dr. Sullivan is provided below and can be accessed by clicking the link on this page. Senator Fischer's letter is also available from this page.

Wind turbine collapses in Northern Ireland

A 328-foot tall wind turbine worth more than £2 million has buckled and collapsed on a mountainside in Northern Ireland. Unconfirmed reports suggested the blades of the turbine had spun out of control - despite only light wind speeds - before the structure came crashing to the ground on Friday.

Wrecked: Turbine in Co Tyrone, Northern Ireland blown down

Screggagh-turbine-collapse_thumb Wrecked: A Nordex N80 2500kw wind turbine lies in a mangled heap after it was blown over at the Screggah windfarm in Co Tyrone, Northern Ireland. The wind facility consists of eight 2.5 MW turbines and was placed into service in March, 2011. For more pictures visit this site. Prior to the collapse, thunder-like noise coming from the turbine could be heard 7 miles away across the valley. Turbine debris was scattered hundreds of meters away from the turbine's foundation according to a BBC video news report.

Grinding Gearboxes – Better Call Roy

As the fleet in more established wind power markets such as Australia, Europe and the United States continues to age, the projected “20-year lifecycle” of a wind turbine has often mistakenly been applied to internal components in post-warranty operational expenditure budgets. Despite great strides in gearbox reliability, such advances have not always been consistently adopted industry-wide for financial reasons.

Riverside Stadium wind turbine developer set to launch multi-million pound legal action against Durham Tees Valley Airport

Mr Millinder said the money from electricity the turbine could already have generated has been lost, and that he will look to sue DTVA to recover the company’s losses. He said: “I would lay the blame at the door of the airport. We have lost around £2.8m from the tariff. ...There is no technology available that would have been able to satisfy the airport’s submission."

Brazil - 8 wind turbines collapse in high wind conditions

Iwt-collapse-brazil2_thumb A storm that hit the Rio Grande do Sul with winds of 250 km / h (155 mph) dropped eight turbines at the Wind Complex Cerro Chato Eletrosul in Santana do Livramento, a town 492 kilometers from Porto Alegre. Enercon GmbH’s Wobben Windpower erected the first 45 wind turbines (Enercon model E-82 2 MW) at the site beginning in 2010. Prior to this latest incident, there were 108 turbines, each at 2MW for a total of 216 MW.

Wind farm bosses given more time to tackle radar issue in Northumberland

Permission was subject to a condition that the developer had 12 months in which to agree a scheme to mitigate the effects of its turbines on the primary surveillance radar at Newcastle International Airport. The company  asked the county council to be allowed to remove the condition, and to vary the condition on turbine height to instead allow 130m models to be used. The council approved the first request but refused the second.

GE Turbine collapse in Kansas

Ge-kansas-turbine-collapse_thumb A GE 1.85 MW turbine (#D12) with an 87-meter rotor collapsed at the Buffalo Dunes wind farm, located near Garden City, Kansas. The failure occurred in the morning of Monday, Dec. 15, 2014. It was not clear at the time if weather was a factor. An investigation is underway.
