Utility-scale turbines are ones that generate power and feed it into the grid, supplying a utility with energy. They are usually much larger than turbines that would feed a homeowner or business. The regularly updated database has wind turbine records that have been collected, digitized, and locationally verified. Turbine data were gathered from the Federal Aviation Administration's (FAA) Digital Obstacle File (DOF) and Obstruction Evaluation Airport Airspace Analysis (OE-AAA), the American Wind Energy Association (AWEA), Lawrence Berkeley National Laboratory (LBNL), and the United States Geological Survey (USGS), and were merged and collapsed into a single data set. Verification of the turbine positions was done by visual interpretation using high-resolution aerial imagery in ESRI ArcGIS Desktop. A locational error of plus or minus 10 meters for turbine locations was tolerated. Technical specifications for turbines were assigned based on the wind turbine make and models as provided by manufacturers and project developers directly, and via FAA datasets, information on the wind project developer or turbine manufacturer websites, or other online sources. Some facility and turbine information on make and model did not exist or was difficult to obtain. Thus, uncertainty may exist for certain turbine specifications. Similarly, some turbines were not yet built, not built at all, or for other reasons cannot be verified visually. Location and turbine specifications data quality are rated and a confidence is recorded for both. None of the data are field verified. The purpose of this information is to provide a regularly updated, publicly available, spatially referenced, national dataset made up almost entirely of utility-scale wind turbine locations and their technical specifications. An appropriate use of the data would be for scientific analysis, research or for general interest for the public. Identification of turbines that have been retrofitted, repowered, decommissioned, and/or removed is a continual ongoing effort; thus, the dataset may contain turbines that were previously verified and subsequently removed. Credit to cooperative agreement and collaboration between the U.S. Geological Survey, the Lawrence Berkeley National Laboratory, and the American Wind Energy Association to compile and release these data.

None of the data are field verified. 1 -101.753593 -94.942856 39.892506 37.073135 No formal logical accuracy tests were conducted. Data set is considered complete for the information presented, as described in the abstract. It is regularly updated and turbines will be added and removed over time, and characteristics might be altered over time as well. Users should be aware that the location data was based on a snapshot of time; turbines could have been removed after that time or built since the image date. None of the data are field verified. Turbine data points were spatially verified in aerial imagery to confirm or edit their correct position. The map scale used while verifying and digitizing turbines depended on location, need, and imagery availability. Authors used aerial imagery with a typical assessment map scale of 1:2,000 to 1:5,000, none of the spatial verification was done at a map scale smaller than 1:5,000. Uncertainty may exist for certain turbine locations as indicated in confidence turbine location field (t_conf_loc). Uncertainty in turbine specifications was indicated in the confidence of attribute field (t_conf_atr). The wind turbine points were horizontally verified with aerial imagery as specified in the image source attribute. NAIP provides 1 meters ground sample distance orthoimagery to within plus or minus 6 meters to true ground at a 95-percent confidence level. The Bing Maps Aerial basemaps and Digital Globe imagery have a variable resolution and accuracy based on image source, type, and location. The Bing Maps Aerial basemaps horizontal accuracy for CONUS is estimated to be 0.3m to 0.03m. Digital Globe imagery is estimated to be 0.3m to 0.03m. A formal accuracy assessment of the vertical positional information in the data set has either not been conducted, or is not applicable. Prior to steps listed below, US wind turbines were identified, mapped, and verified by USGS for a separate dataset: "Onshore Industrial Wind Turbine Locations for the United States to March 2014". A description of the process to develop that dataset can be found in the metadata file for that release (https://doi.org/10.5066/F7251G8Q). Building off this earlier effort, the following steps were taken to expand and update the United States Wind Turbine Database (USWTDB) with the collaboration between USGS, LBNL, and AWEA. Please note that some steps are iterated on a quarterly basis to keep the dataset current. (1) The March 2014 USGS dataset 48,956 turbines, 34,864 of which had unique FAA Obstacle Repository System (ORS) numbers was merged with (2) the LBNL wind turbine dataset. It had previously existed separately in house, and also had the FAA ORS number as well as many of the same fields as the USGS dataset. It was merged into the USGS dataset using the ORS number, bringing in LBNL fields and IDs. (3) Non-matching LBNL turbines were also added as LBNL only turbines. (4) The most recent FAA Digital Obstacle File (DOF) was downloaded and filtered for "windmills", and reprojected from WGS-84, as FAA provided it, to NAD-83 datum, the USGS and LBNL datum. These new coordinates were used later in the process. (5) The DOF dataset was then merged into the working USWTDB using ORS number, keeping new (non-matching) DOF Only turbines, and DOF variables (faa_aglht, faa_amslht, faa_asn, ylat, xlong). (6) The most recent FAA Obstacle Evaluation Airport Airspace Analysis (OE-AAA) file was downloaded and filtered for "windmills". (7) The OE-AAA dataset was merged into working USWTDB using Aeronautical Study Number (ASN) and preserved as the faa_asn attribute,keeping new (non-matching) turbines as OE only and OE-AAA variables (oe_builtdate, oe_appdate, oe_expdate, oe_comdate, notice of, status, dtrmntn, oe_aglht, ylat, xlong). (8) The latest AWEA WindIQ turbine dataset was downloaded. (9) A geospatial match between AWEA turbines and working USWTDB was performed using "geonear" command in Stata statistical analysis software and the following steps: [a] Save separate AWEA and working USWTDB datasets. [b] Run "geonear" command in Stata between the two datasets to determine and "match" nearest neighbors (i.e., these turbines are suspected to be the same turbine but from the two different datasets), and calculate the distance between them. [c] Calculate differences in installed year, hub height, rotor diameter, and total height between "matched" turbine pairs. [d] Accept "match" (meaning assume they are, in fact, the same turbine) IF distance between pairs is zero (perfect geospatial match), OR distance between pairs is less than 100 feet (30.5 m) AND hub height, rotor diameter, and installed year are equal between the pairs. If the match criteria were not met, both turbines in the pair were saved for subsequent visual inspection and "manual" confirmation of match. Non-matching AWEA turbines are added to the dataset as AWEA-only turbines and all AWEA variables (turbine ID, p_year, t_cap, t_hh, t_rd, t_tth, ylat, xlong, t_manu, t_model, t_state, as well as other variables) were added to the dataset. (10) A hierarchy was developed because multiple datasets contain some of the same fields (e.g., t_ttlh was contained in USGS, LBNL, DOF, OE-AAA and AWEA datasets)Because LBNL and AWEA data are sourced from two high-quality sources (OEMs and developers) and reconciled to eliminate differences, LBNL data is the primary source for turbine attributes and turbine project characteristics, then AWEA, USGS, DOF, and finally OE-AAA. In the overwhelming majority of cases, differences between sources were minimal, but when discrepancies existed that order was used to populate fields. All fields that are missing from higher-order sources are populated from lower sources. (11) The working (i.e., fully merged) USWTDB was spatially joined with base layers via ArcMap in order to pin t_state, t_county and t_fips to turbine points. (12) Turbine points were selected by state, saved as an individual turbine file for each state, and distributed to authors for editing. (13) A basemap image from Digital Globe was added to the ArcMap project file. If Digital Globe imagery did not show a turbine installation, USDA/NAIP County Mosaic Orthoimagery Google Earth imagery was cross checked. Previous bing map image source was retained for some of the previous USGS data. (14) Turbine points were visually verified and edited/moved to the base of the turbine as needed with an estimated tolerance of 10 meters. (15) If the turbine data point was not seen on an image, the t_conf_loc was entered as 1. If the turbine point was in partial construction or with other doubts, the t_conf_loc was entered as 2. If a turbine was clearly seen on image, the t_conf_loc was entered as 3. Turbines that have not yet been visually verified are labeled with 0 in t_conf_loc. (16) Turbine points that had existed previously but were since decommissioned and removed were flagged as decommissioned and later removed( see step 20). (17) Duplicate turbine points (largely resulting from AWEA geospatial merge) were identified and t_img_date, and t_img_srce were attributed for each turbine. (18) Non-turbine points that had been assigned FAA Obstacle Repository System (ORS) numbers or were digitized in the process such as communications towers, meteorological towers, water windmills, power transmission towers, etc., were removed. (19) Edited wind turbine files for each state were merged into one single shapefile, turbines identified as duplicates were matched, all fields were collapsed into a single turbine observation, and duplicate points were removed. (20) Turbines flagged as decommissioned were removed. (21) QA/QC was conducted for spatial accuracy and attribution by a peer or a supervisor other than the author that initially completed the work. As noted above, steps 4-21 are repeated on a quarterly basis, using the most recent USWTDB as the starting point. 2018-10-20 Source information used in support of the development of the data set.
