The measurement equipment is based on a standard NRG- system with sensors for measuring wind speed, wind direction and temperature.

All instruments and logger are mounted on a 10m guided mast.

The sensors have not been selected for operation under artic conditions.

Fluid Mechanics Section, DTU Mekanik Technical University of Denmark SUSTAINABLE ENERGY SUPPLY IN THE ARTIC Sisimiut, 1-3 March 2008 Conclusion

• Wind resources at Sarfannguaq, seems to be very interesting in a wind energy perspective. • Wind resources at Dumpen near Sisimiut seems also to be interesting in a wind energy perspective. • Four sites in Umanak commune need more measurements. • One or two might be interesting - in a wind energy perspective.
