Capacity figures are calculated by calculating, for each turbine in a given wind farm, the number of hours since it was first connected to the grid. This is then multiplied by its capacity, to give the number of peak-MW-hours. These figures are summed across all turbines in a wind farm, and divided into the total energy generated by that wind farm, to give its capacity factor.
For example the average capacity factor across Denmark’s 13 off shore wind farms was 45.3% YE Oct 2015
