Will heat be the winner in de-icing turbine blades?

Interesting that the wind industry is concerned about ice falling on people and cattle but the MOE is not aware of any concerns.

The wind industry is trying to find improved methods of prevention of ice, and the MOE is satisfied with the present system.

When it comes to keeping wind turbines operating smoothly in icy conditions, there are several approaches being considered and tried, from the highly technical to the old school ‘shiver’ technique.By Susan Kraemer Some of the best wind resources in the world are in some of the coldest regions. These regions, with the best potential for wind energy because of their sparse population and favourable wind conditions, are expected to host 72 per cent of new wind farms through 2017, according to Finland’s State Technical Research Center Valtion Teknillinen Tutkimuskeskus (VTT).

But howling winds and temperatures as cold as -35 C can place enormous demands on wind turbine systems – and on the incomes of wind farm operators, because ice build-up on blades can reduce electricity generation by as much as 20 per cent.
