U.S. Average Annual Capacity factors by project and State

This spreadsheet shows production data for the Energy Information Administration sample of wind projects in the US, by State, for the years 2011 and 2012. Average annual capacity factors by project, State, and for the United States were determined after knowing the installed capacity for each project. The spreadsheet has three tabs with the first showing a summary of the two years. Note: EIA changes its sampling of projects by year which is why the lists from one year to the next differ.

A composite map of the U.S. with the capacity factors shown can be found here .

The summary table is provided below. Total MWs installed also includes projects with less than one-year of production data. Capacity factors were determined based on projects with at least one full year of production ('MW Considered').
