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.

The map below provides wind capacity factors by state for 2013 that were calculated from Energy Information Administration (EIA) data. (instituteforenergyresearch.org)
Wind capacity factors can vary greatly across regions because the output from wind turbines are dependent on the wind resources in the area. (instituteforenergyresearch.org)
