Air Repair: Cracked blade replaced at Corn Plus

When it came time to start repairing a wind turbine at the ethanol plant on Oct. 15, the project had to be put on hold. ..."The blade has been cracked all summer. It's been frustrating," says Dan Moore, director of project development for Renewable Energy Solutions. When the broken blade was discovered, the turbine furthest from the ethanol plant had to be shut down. All three blades needed to be replaced, says Moore, because we couldn't find one to match the other two.

Fatal accident points out transport challenge

A broadside accident occurred Wednesday in St. Cloud between an oversized-load truck carrying wind turbine parts and a minivan, resulting in one death. Millard and Shirlee Nelson of South Haven were heading north at the intersection of Highway 15 and Second Street about to turn left. ...The number-one thing MnDOT can do in wind turbine transportation is ensure the public's safety on the roads, Coulianos said. Coulianos also said for the three and a half years he's worked for MnDOT, this is the first fatality he's known involving transportation of wind turbines. "This is what we plan not to happen," Coulianos said. "This is very serious to us."

Windmill fire under investigation

Emergency calls flooded the Jackson County Law Enforcement Center last Wednesday morning as passers-by on Interstate 90 in western Jackson County witnessed huge plumes of smoke ascending to the clouds. The fire originated from one of the six power-generating windmills on the Ewington Township Wind Farm, located south of Okabena just north of I-90. ...After the fire was controlled, the scene was turned over to Suzlon officials, who are conducting an investigation. "We are still investigating a cause," said Suzlon Vice President Ken Glazier. "The fire was controlled quickly and brought to a safe stop.

Lightning hits wind turbine, starts fire

A wind turbine near Dodge Center lost one of its blades Friday night when lightning struck it and started a fire. The Rochester Fire Deparment was called to the fire because it had the closest long-ladder truck. Its 100-foot ladder was used to help extinguish the fire at 11:15 p.m. One rotor blade was lost, but fire officials were uncertain if the fire reached the generator portion of the device, which could compound the loss.

DOD report says wind farms will affect military readiness

MILWAUKEE - Large turbines generating electricity in a radar line of sight can harm the ability of air defense radars to detect and track aircraft or other aerial objects, the U.S. Department of Defense said Thursday in a new study. The only way to make sure that U.S. forces can perform their air defense missions is to avoid putting the wind turbines in the line of sight of the radars, said the report submitted to the Senate and House Armed Services committees. Efforts have started to find other ways but they "require further development and validation" before they can be used, given that some turbines with rotating blades reach 500 feet high, the report said. "The numbers, height and rotation of these wind turbines present technical challenges to the effectiveness of radar systems that must be carefully evaluated on a case-by-case basis to ensure acceptable military readiness is maintained," the report said.
