Turbine issues fixed in Osceola County

The company submitted records to the county showing the agreements have been reached. Levy said the agreements have been executed and the company would e-mail copies of them to the county. In cases where NextEra could not reach agreements with landowners, the company curtailed operations of turbines close to the county residents’ homes so the machines are within the acceptable noise and shadow flicker limits.

Fire damages wind turbine near Westboro

"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. We were advised by Iberdrola not to approach the turbine, just due to the safety factor, because there was a lot of debris that was burning and falling off.

School's wind turbine's energy production on hold

Blades the length of almost two school buses from a wind turbine owned by Akron-Westfield School District rest on the ground while repairs are underway. The turbine's gearbox was also brought down using a tall crane to reach the top of the 11-year-old structure's 165-foot-tall tower, which is much higher than people realize, said Dwain Wilmot, A-W technology coordinator. "You can see Vermillion (S.D.) on a good day," Wilmot said, if you stand on the top of the wind turbine tower. "I've only seen it once or twice."

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.
