8. 8 Risø DTU TFI Annual Conference 15. September 2010 Did you know? The installed wind energy capacity in EU produce 4.8% of our electricity – 20% in Denmark. In 2009 for the second year running more new wind was installed than any other technology (39% of all new) 10 GW was installed in EU – globally 38 GW 2.8% is offshore wind in EU 106 mill t CO 2 avoided ~25% of our cars removed €6 billion avoided fuel cost 192.000 people employed in the EU Source: European wind energy association

18. 18 Risø DTU TFI Annual Conference 15. September 2010 IceWind project – key figures Title: Improved forecast of wind, waves and icing Project period 1. September 2010 – 31. August 2014 Overall budget 20.8 mill NOK Financial support TFI 12.3 mill NOK Ekstern financing 8.5 mill NOK Partners: 13 375 man-months (45,000 hours) over 4 years Coordinator Risø DTU, Niels-Erik Clausen 4 PhD projects planned: Two in Iceland, one in Denmark and one in Sweden

19. 19 Risø DTU TFI Annual Conference 15. September 2010 IceWind objectives The overall objective of the project is to support the development and integration of wind energy in the five Nordic countries by focussing on three main areas: 1.Icing on wind turbines (atlas, forecasting and losses) 2.Integration of wind energy on land (Iceland) 3.Offshore wind energy (forecasting and access) A key issue is to share knowledge among the five Nordic countries and to work in areas where differences in know-how exist and where barriers or challenges prevent or slow down a large penetration of wind energy in the Nordic grid.

21. 21 Risø DTU TFI Annual Conference 15. September 2010 IceWind work packages WP 1 Icing (lead VTT) –Atlas of icing for Iceland and Sweden, forecast of icing, estimate of losses due to icing WP 2 Iceland (lead Iceland met office - IMO) –Wind atlas, identification of sites, technical and market integration studies WP 3 Forecast and O&M (lead met.no) –Offshore meso-scale effects of large wind farms incl. wakes, short term forecasting, maintenance strategies and availability issues WP 4 Power and energy aspects (lead Risø) –Spatial and temporal variability of wind resource, forecast errors and their impact on the Nordic power grid and balance market.

22. 22 Risø DTU TFI Annual Conference 15. September 2010 Expected results Better forecasts of wind and waves Maps of icing occurence and losses Better knowledge on wake losses in very large wind farms Wind and ice atlas of Iceland Integration study of wind in Iceland Better understanding of the interaction between hydro and wind in the Nordic system
