For the 2020 Medium scenario the countries studied showed an average annual
wind capacity factor of 23 — 25 %, rising to 30 — 40 %, when considering power production during the 100 highest peak load situations — in almost all the cases studied, it was found that wind generation produces more than average during peak load hours.
Wind capacity factors can vary greatly across regions because the output from wind turbines are dependent on the wind resources in the area.
Another example of the variability of
wind capacity factors is that of Hawaii, whose wind capacity factor was almost halved between 2012 and 2013.
