58 still closed by runaway windmill

A runaway windmill in Tehachapi closed Highway 58 -- a major east-west freeway connecting California's southern Central Valley to Las Vegas, Nevada and Arizona -- for most of the day Sunday. As of 6:45 p.m., the highway remained closed between Tehachapi and Mojave. Officials had no estimate as to when it might reopen

Windmill falls over in North Palm Springs

It could be a major safety hazard, windmills near the 1-10 in North Palm Springs crashing down to the ground. It happened yesterday, and now there's an investigation as to why the wind turbine, nearly 200 feet fell. "It went into overspeed, some sort of maintainence or some sort of malfunction," said Jeff Welton of the Palm Springs based Wintec Energy.

Wind turbines could resume spinning soon

A blown transformer that has idled scores of wind turbines at the Smoky Hills Wind Farm for about four months is expected to be replaced soon. "If all goes well, it should be online in the next couple weeks," said Cinthia Hertel, a spokeswoman for Sunflower Electric Power Corporation, one of the utilities with contracts to receive power from the wind farm, which is located along Interstate Highway 70 at the Ellsworth/Lincoln county line.

NREL gearbox study aims to grease wind power's future

At NREL, senior engineers are expanding a research partnership with operators, utilities and turbine manufacturers to determine why some key wind turbine components tend to wear too soon - sometimes within a few years of installation. That's a problem because wind turbines are expected to operate for 20 years. Early equipment fatigue, especially in turbine gearboxes, threatens to reduce performance and drive up wind power costs just as the industry is poised to capture a greater share of U.S. generating capacity.

New blades for wind turbines

New blades will be installed on four turbines that were shut down temporarily at two locations in the area. A crew yesterday replaced the blades on the wind turbine at Turtle Plastics in Lorain. New blades also will be placed on three turbines at Perkins High School in Perkins Township. The four turbines were built by the same company and were shut down to ensure safety after the blades broke off a turbine at Perkins High School.

PSC probes wind tower collapse, fire; Debris analysis, other information from Clinton County incident sought

State investigators from the Public Service Commission are looking into the fiery collapse of a wind power turbine at a turbine farm in Clinton County. A preliminary examination by Nobel Environmental Power, owner of the $200 million, 65-turbine Altona Wind Park, and General Electric Co., manufacturer of the 1.5-megawatt turbines, found "wiring anomalies" prevented two turbines from shutting down as designed during a power outage.

"Wiring anomaly" found in fallen turbine

Noble Environmental Power officials say they have detected a "wiring anomaly" in two Altona wind turbines, including the one that snapped in half last Friday. As the preliminary investigation continues into how a massive turbine suddenly collapsed, Noble officials said this week that the entire wind park experienced a loss of power Friday and that two of its 65 turbines apparently malfunctioned.

Residents shocked by wind-turbine collapse

Many residents were shocked that a massive wind-turbine could come tumbling down and officials say it could take months to learn why one collapsed Friday. Mike Fellion flew over the wreckage Saturday morning and was amazed to see that pieces of the structure appeared to have been thrown "about a quarter-mile away."

Noble Environmental Power confirms Altona turbine collapse

Noble Environmental Power has confirmed that a turbine collapsed at its Altona, N.Y., wind park Friday morning, but said no one was injured in the collapse and ensuing fire. In a statement released by the company Friday, company spokeswoman Maggy Wisniewski confirmed one turbine had collapsed and that a small fire resulted, but she refused to speak on the record with a NewsChannel 5 reporter.

Fire burns windfarm on US 277

The Rhodes Ranch fire, as it has been named by the Texas Forest Service, has been burning for several days, starting in the Mulberry Canyon area, northwest of Coronado's Camp. It had been considered under control until Thursday when it flared back up, forcing officials to shut off access points to the area.

Wind crashes Waverly turbine

A 50-ton structure fell 246 feet to the frozen ground on Saturday when the blades of a turbine under construction east of Waverly caught wind and started rotating at a speed reaching 60 rpm. The hub housing the generating components of the Cannon II turbine and the structure's three 177-foot blades collapsed after spinning for hours at the mercy of the wind, says Waverly Light and Power General Manager Diane Johnson. A gust caught the blades prematurely on Friday.

Part of wind turbine breaks and lands in open field

Part of a wind turbine under construction broke apart Saturday morning. The problem started Friday when construction crews were installing a second wind turbine for Waverly Light and Power. During the process, a construction error caused the rotor and blades to start moving in the wind prematurely - spinning uncontrollably and unable to stop until it broke.

An unexpected problem has occurred with construction of second wind turbine

The construction company, ICS of North Dakota, lifted the wind turbine rotor assembly, to which the blades attach, 246 feet high into place late yesterday afternoon. After it was lifted it was discovered the blades were not ‘feathered' or turned properly so they could not catch the wind. In the position the blades are in, the wind caught the blades causing them to spin. When this was discovered, the Bremer county sheriff's department was notified and all personnel were evacuated, including two homeowners who were outside of the recommended danger zone.

Turbine blade slashes into neighbouring home

Bill Fish wants the Municipality of Chatham-Kent to investigate homemade windmills after his neighbour's device came crashing through his roof during yesterday's high winds. He was shocked awake around 3 a.m. when an eight-foot-long wooden blade penetrated the roof, before piercing through the ceiling and wall in a sewing room of his Dufferin Avenue home, located outside of Wallaceburg in Chatham Township.
