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 halts northern N.B. wind farm

Northern New Brunswick's cold, icy weather is causing wind turbines to freeze and stop producing power at the Caribou Wind Park near Bathurst. The new wind farm's 33 turbines have been generating power since November, but they have been forced to shut down for the past two days due to ice forming on some of the blades.

Wind operator shares lessons from Whittlesey ice-shedding

A wind developer that became a "lightning rod" for the industry when one of its turbines started shedding ice in December, has revealed its latest strategy for dealing with ice build-up, writes Rachel Johnson. ..."We knew icing would occur but believed our turbines would stop in the event of an ice build up," he said. The investigation revealed that the most widely available guidelines on icing, including those from the BWEA, had said that wind turbines are designed to shut down in the event of an ice build up.

Wind farm has precautions against ice throws

Even when it comes to the giant blades of the turbines in Amaranth and Melancthon, there might be truth in the old expression that "it's an ill wind that blows no good." This might have been the case when the Melancthon I wind project had to be shut down for nine days in December 2006 because of an ice storm and the resultant imbalance of the blades.

Sensor fails to stop ice-terror wind turbine

A sensor which should switch off a wind turbine in icy conditions has failed - for the second time. As reported in The Evening Telegraph last week, a faulty sensor on the turbine in King's Dyke, Whittlesey, was blamed for huge shards of ice flying off its blades and crashing into homes and gardens in November. ..."The turbine was shut down immediately after we were alerted, and will remain in this state until further notice."

Turbines could get 'iced up'

A Meridian Energy witness was scrutinised for not considering Central Otago's harsh winter, which could shut down wind turbines in times of high demand. The Environment Court hearing into the $2 billion Project Hayes windfarm continued yesterday with wind energy consultant Graham White appearing for Meridian. He said in freezing humid condition wind turbines could ice up and no longer operate.
