Here are the average capacity factors of every Danish offshore wind farm, newly updated to include data to the end of 2016. The Anholt 1 windfarm, which only opened in 2013, hit an average capacity factor of 47.4% for the full year 2016. Compare these with the capacity factors for UKoffshore wind farms. Thanks to the wonderful statisticians and data managers at ENS and Energinet.DK, we have a large amount of detailed data from Danish onshore and offshore wind farms.
Danish windfarms also include the most productive wind turbines in the world, at Rønland I: the turbines have been operating for over 14 years now, with a lifetime capacity factor of 44.5%; of its eight turbines, four are rated at 2.3MW peak power, and each of those four had by the end of July 2014 generated over 100 GWh: the first turbines to pass that milestone.

Calculation method
Just as with the UK offshore windfarm capacity factors, these capacity factors 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.
