Commissioners again discuss wind tower ice sling

Wilcox, who has raised concerns before about wind tower farms in the county, said more needs to be done to address ice sling, suggesting the commissioners implement a fine to be assessed if towers where ice sling is occurring and landing on county roads. She said the safety of county residents is in question on county roadways when such conditions exist.

Iowa State researchers seek solution for icy wind turbine blades

Technologies exist that can be built into the turbine. Although they are used in Canada, Denmark and Sweden, Hu said the U.S. wind industry has found them to be cost-prohibitive.... blades can incorporate a material that conducts electricity that can prevent icing by warming the blade. He said the cost for the power amounts to roughly 5% of the energy a turbine might typically produce.

Falling ice from wind turbine worries family near proposed project

Days after several Freeborn County wind turbines had to be shut down after a chunk of ice fell off a blade and landed on a passing semi truck, a family whose home lies within feet of the proposed Freeborn Wind Farm project said they're concerned about something similar happening at their home. ..."I'm sorry but [...] there's no amount of money that's enough comfort for my kids being put in harm's way," he said.

Expanding Balsams ski resort: money, jobs and a regulatory challenge

Using an industry rule of thumb, the setback for turbines likes those in the North Country would be about 800 feet, says Rene Cattin, a Swiss researcher who studies wind turbines in cold weather. But, Cattin said, his research shows that ice isn’t thrown more than about 500 feet. However, there are safety issues beyond ice throw, issues that could occur year-round.

Ice-Tossing Turbines: Myth or Hazard?

The wind industry concedes that, as with all tall things (buildings, for example, or trees), ice and snow can build up and, eventually, fall down, creating a hazard to people and structures below. But the industry denies that "ice-throwing" - another concern surrounding wind power - is a problem. ...But a 2006 publication by G.E. Energy, a maker of large wind turbines, warns that "rotating turbine blades may propel ice fragments some distance from the turbine - up to several hundred meters if conditions are right."

Grant resident questions potential ice hazards of wind farm blades

Dominion Power and the Grant County Commission responded to a Mount Storm resident's concerns about the potential for ice on the blades of wind turbines this winter. Bruce Halgren of Mount Storm appeared before commissioners Jim Wilson, Charlie Goldizen and Jim Cole Tuesday. He said that he is concerned that the proximity of some of the NedPower wind turbines being constructed along Grassy Ridge Road could present a safety hazard to motorists from ice and debris being thrown off by the turbine blades in the wintertime.

Mountaintop residents cite wind turbine issue, want county to oppose some towers

The reception was somewhat on the chilly side, Tuesday, when a pair of mountaintop residents brought their protests about windpower electricity to the Grant County Commission. Residents Bruce Halgren and Richard Spicer appeared before commissioners as part of a campaign to reduced the number of windpowered turbines being erected in the community by NedPower and Shell Renewables and Hydrogen. The pair asked commissioners to oppose six turbines to be constructed within 820 feet of public roadways. They say the turbines present an "ice throw" hazard to motorists on Grassy Ridge Road and state Route 93.
