Capacity factors at Danish offshore wind farms

Posted by – 2014/07/23

monthlygenHere are the average capacity factors of every Danish offshore wind farm, newly updated to include data to the end of June 2015. The Anholt 1 windfarm, which only opened in 2013, hit an average capacity factor of 50.9% for the full year 2014. 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 12years now, with a lifetime capacity factor of 44.3%; 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.

All numbers are to the end of June 2015. Analysis by EnergyNumbers.info. Raw data from ens.dkLatest

Calculation method

The 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.
