The net annual energy production (AEP) of the Hanstholm Wind Farm is 158 GWh
per year for the Siemens SWT-3.6-120 turbine and 140 GWh for the Vestas V112-3.0 turbine.
These values have an uncertainty (standard deviation) of 6%. This result is mainly based on the
data for Risø DTU’s test station at Høvsøre where wind speeds are measured at approximately
the same height as the turbines at Hanstholm and where the terrain is similar. On top of that
meso-scale modeling has been used to extrapolate the climatology from Høvsøre to Hanstholm
increasing the AEP by almost 6% compared to just using the Høvsøre climatology directly. This
method of extrapolation is rather new, but several older investigations indicate that the wind
resource at Hanstholm is slightly higher than at Høvsøre.
The work is carried out for Grontmij-Carl Bro according to a contract dated January 18th 2011.
