US Wind production and capacity factors 2011-2015

The U.S. Energy Information Administration provides monthly and annual production data for over 10,000 power plants including wind-powered facilities. Windaction.org has been tracking this data closely since 2011 with a specific focus on wind power plants. The below table lists the annual aggregate capacity factors for each state that EIA has reported wind production for projects with at least one full-year of production. A breakdown of the production data by state and individual projects in each of the years 2011 - 2015 can be accessed by downloading the documents attached to this page. Editor's note: Windaction.org, endeavors to present the most current and accurate information available. If readers identify a problem with any of the data, please contact us at info@windaction.org. In an effort to ensure accuracy, the attached data files may be updated from time-to-time. (Data files updated on April 2, 2016)
