Icing is an important issue when operating wind turbines in high altitude or arctic areas as it can cause significant production losses and represent a safety risk. In 2004, a 600 kW Enercon E-40 wind turbine with integrated blade heating was installed on Gütsch mountain, Switzerland, at 2’300 m asl. Coincidentally, a fully equipped test station of the Swiss meteorological network SwissMetNet is situated about 200 m from the wind turbine. The immediate proximity of the two facilities operating under icing conditions led to the launch of the national research project “Alpine Test Site Gütsch” which is embedded in the European “COST Action 727: measuring and forecasting atmospheric icing on structures”.

CENTRE OF ATTENTION: One of the turbines in the Glens of Foudland windfarm which has been shut down pending an investigation into a bullock’s death.
The biggest windfarm in Aberdeenshire has been shut down for four days amid fears of electrocution after a farm animal was found dead.
All 20 turbines at Glens of Foudland, near Huntly, were switched off on Thursday after farmer John Wink found the bullock lying in a nearby field.
The cause of death has been described as unexplained but the previously healthy one-year-old showed haemorrhaging around the heart,… Read more
Despite all that has been written about wind power, a vitally important issue has barely been mentioned. When turbines fail, blades may fall to the ground or send fragments that land up to a mile away. Turbines often catch fire, and when they do they often send flaming shards into fields and forests.
This article includes all documented cases of wind turbine related accidents which could be found and confirmed through press reports or official information releases up to 30 June 2010. CWIF believe that this compendium of accident information may be the most comprehensive available anywhere.
