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 CO2 avoided ~25% of our cars removed

• €6 billion avoided fuel cost

• 192.000 people employed in the EU

Potential for Electricity production from offshore wind power plants

The North Sea alone would do just about half of the world’s present need.


THREE CHALLENGES IN A NORDIC CONTEXT

Offshore operation and maintenance


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


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.

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.


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
