The relative impact of the climate change from 1961-1990 to 2021-2050 on wind power potential in Finland was estimated using data from the HadCM3 global climate model of the Hadley Centre in UK, with the SRES emissions scenarios A2 and B2. The wind power was estimated for a 1500kW wind turbine with height of nacelle of 80 m a.g.l. The wind distribution was calculated for four seasons assuming the Rayleigh distribution for wind speed and taking into account typical surface roughness for each grid. In general, the A2 scenario indicates larger increase in wind power potential than B2. According to the A2 scenario, average wind power potential would increase about 7% at representative regions of Finland. Data from the SMHI Rossby Center simulations for the period 2071-2100 using the regional scale models indicate that the increase in the wind power potential could be even more pronounced, and that the main increase will take place at the sea areas.
