Here are the average capacity factors for offshore wind farms in UK waters, newly updated to include data to the end of September 2026 (though there are still some figures to come through for the most recent couple of months, but only for the smaller windfarms). All operational UK windfarms are presented here, along with closed demonstration sites for which data is publicly available.
The load-duration curves at the bottom of this page show the differences in distribution of outputs: click on the individual farm names in the legend, to toggle the display of individual curves.
You might be interested in comparing these with the capacity factors and load-duration curves for Belgium, Denmark and Germany.
