The turbines start to generate power at 3 m/s and reaches full capacity at 15 m/s. The wind turbines run with a special storm control feature that enables them to operate at extremely high wind speeds i.e. a cut-out speed of 34 metres per second.
The drive system for the wind turbines is a direct drive this means that the inner ring of the annular generator and the rotor of form one unit. These two components are flanged directly to the hub so that they both rotate at the same low speed. The wind turbines operate at a rate of between 16-34.5 RPM.
The northeast wind direction is prevailing on site. The wind flows from the highlands and creates a natural wind tunnel between the Næfurholt Mountains and Búrfell Mountain. The result is strong and steady wind.
