In 2016, USGS, LBNL, and the American Wind Energy Association (AWEA, the predecessor of ACP) began collaborating on development of the USWTDB. Their goal was to create a joint product that would be more comprehensive and accurate than their individual wind turbine data sets. Federal agencies began using these combined data in April 2017, and in April 2018 the data were released to the public via this portal.
These data are used by government agencies, scientists, private companies, and citizens for a variety of analyses. Examples include operational impact assessments of turbines on air defense radar, weather and general aviation, analyses related to the role of wind energy in the U.S. electric grid, interactions between wind energy facilities and wildlife, and investments in wind energy infrastructure.
The data were created by combining publicly available data sets from the Federal Aviation Administration (FAA), USGS WindFarm data from a prior effort, online sources, and data privately held by ACP and LBNL. The locations of all turbines were visually verified to within 10 meters using high-resolution imagery. Technical specifications of the turbines are based on the make and model and other information collected.
With the release of this public version, we hope researchers and other interested parties around the world will use the data to further their efforts. If you have feedback or want to let us know how you are using the data, send us a note.
The USWTDB Viewer, created by the USGS Energy Resources Program, lets you visualize, inspect, interact, and download the most current USWTDB through a dynamic web application. The USWTDB Viewer replaces an earlier web application called WindFarm and includes many enhancements made based on comments and suggestions from WindFarm users. Data-driven styling and expanded filtering capabilities make accessing the USWTDB information easier and quicker than ever. Get started with our quick start video. Your feedback continues to be important to us so don't hesitate to let us know what you'd like to see in future releases.
The latest release includes data on 68,792 turbines covering 44 states (plus Guam and PR). The most recent turbines added to the USWTDB became operational as recently as the fourth quarter of 2020, with a few from the first quarter 2021. The oldest turbines in the data set were installed prior to 1990. USWTDB releases generally lag installations by one quarter to allow for merging of the various datasets, visual verification, and quality control. See more details on the release.
