Windaction.org has updated its database of US wind production and capacity factors to include the years from 2011 through to 2015. The data are based on monthly energy output figures released by the U.S. Energy Information Administration. Aggregate annual capacity factors for each state and for the nation can be found here. A spreadsheet of each project for which production is reported can also be downloaded from the page.

Last April, Reuters and others reported poor winds in some western states during the first quarter of 2015. We checked the preliminary production data released by the Energy Information Administration for that period and, sure enough, the production numbers were way down. The attached spreadsheet compares Q1'15 performance against the same period in 2014. A summary of the capacity factors for the states reporting wind project information is provided below. The full data can be accessed by downloading the attachment on this page. Texas, California, Iowa, Oklahoma and Illinois, which account for 50% of total installed wind in the US, each experienced significant reductions in output for the first quarter. NextEra Energy confirmed the reduction in Texas performance during its first quarter earnings conference call.
“Before Americans are asked to pay more billions for an energy resource that still, after 23 years, cannot stand on its own two feet, Congress should ask DOE to get out of the vision business and report on the practicality of wind energy reaching even 10% of the U.S. power market.”
The U.S. Energy Information Administration provides monthly and annual production data for over 1,900 power plants including wind-powered facilities. Windaction.org filtered the data for the years 2011-2013 looking for wind projects only and determined the capacity factors for each project in EIA's sample list with at least one full-year of production. The below map shows the average capacity factors by state for 2013. (Click the map to see a larger image.)
