I could find this but it's from 2019:

> New offshore wind projects have capacity factors of 40%-50%, as larger turbines and other technology improvements are helping to make the most of available wind resources. https://www.iea.org/reports/offshore-wind-outlook-2019

Below, a diagram shows current numbers as approximately 30%-55% for offshore and 25%-45% for onshore wind.

The article says "Every year, each one is expected to generate 80 GWh of electricity.", which is actually only 9.1MW or 57%.
