Smøla wind power plant was selected as the case on wind power production for comparison with small-scale and large-scale hydropower projects (Statkraft, 2013). Smøla is the largest wind power farm in Norway, located in Møre og Romsdal County (Fig. 1) by the west coast in mid-Norway (Fig. 1), producing in average 356 GWh/year. The annual energy production from Smøla was set as the energy base for the total study.
