Winterwind<\/a>, the largest event focused on wind energy in cold climates, was held from February 3 to 5 in \u00c5re, Sweden.<\/p>\n

As an expert in this field, our colleague Charles Godreau<\/a> He represented Canada on \u201cTask 19,\u201d the International Energy Agency\u2019s (IEA) working group on this important issue. In addition to serving on the event\u2019s program committee, Charles gave three presentations on topics of interest to operators in cold-weather regions.<\/p>\n

Anti-icing Systems: Performance and Experience<\/strong><\/p>\n

Anti-icing systems are one of the options available on the market to prevent ice from forming on wind turbine blades. But how well do they work? Following a literature review of 11 studies published on the subject between 2011 and 2019, the Nergica team concluded that the following observation<\/a>\u00a0: There is no standardized evaluation method in the industry that allows for a comparison of the performance of different de-icing systems.<\/p>\n

A survey (non-probabilistic, conducted online) carried out by Task 19 also provided insight into the industry\u2019s views on anti-icing systems. Nearly 20 respondents from nine countries were surveyed. Of these, 42% indicated that the performance of these systems did not meet their expectations, particularly due to their inconsistent performance.<\/p>\n

According to respondents, the following factors should be priorities for manufacturers of anti-icing systems in order to improve their performance:<\/p>\n
