(Source: WindPRO®3.0) As two different turbines with 25m and 50m hub heights have been used, the wind direction graph at these heights has been generated. As it is seen in Figure 23 the predominant wind [...] of one year has been shown. The most prevalent wind speeds are between 6-8 m/s at 25m height and 7-9 m/s at 50m height. This means that the most commonly occurring wind speed is quite high in Durness and [...] both sites. Hub height selection plays an important role in the energy generation from a WTG. For instance, for Enercon turbines it was observed that an increase of 23.3 m in the hub height would slightly
