Room: Hall G2
Sites subject to cold climate not only have temperatures outside the normal limits of standard wind turbines but also atmospheric icing conditions which are frequent and may account for a significant loss in annual production. This session addresses the most recent advancements in the field of atmospheric icing effects on wind resource yield assessment. Assessing, measuring and estimating icing losses in the resource assessment phase of a project is of crucial importance for the successful business case of a wind farm in cold climates. Icing of the rotor blades can significantly reduce the energy yield of a wind farm up to 10% or more of the annual production and it also influences wind measurements by reducing availability.

Learning objectives
- Learn state-of-the-art measurement techniques and data analysis approaches for cold climate sites and therefore decrease the uncertainty in yield assessments;
- Discover the latest findings from over 20 sites and 100 met mast years of data in cold climates from Scandinavia and Germany;
- Learn to execute more reliable pre-construction energy yield assessments in cold climate sites.

Presenter's biography
Biographies are supplied directly by presenters at WindEurope Summit 2016 and are published here uneditedDr. Grassi has been working in renewable energy industry for more than 10 years and leading research in wind energy at ETH since 2009. He is currently Postdoctoral Researcher at ETH in geoinformation-engineering. He studied environmental engineering at the University of Brescia and Energy management and Policy at the Mines ParisTech in Paris. After his graduation he spent some years as project designer of hydro and biomass power plants in Italy. After a second Master in Paris he moved to Switzerland leading research in spatial planning and modelling in the field of wind and solar energy.
