Description: Wind Turbine Locations (USGS), 20181008 - Shows the locations of utility-scale wind turbines within Indiana, as of October 8, 2018. The data were extracted from the original source data of the "United States Wind Turbine Database" (USWTDB_v1_2_20181001.SHP, ver 1.2, October 2018). Attributes include federal program identification numbers, date of first operational power production, technical specifications and size of the turbine, project names and information, turbine and total project capacity, and imagery basemaps used to visually inspect and adjust final locational positions. The following is excerpted from metadata provided by the USGS: "This dataset provides locations and technical specifications of wind turbines in the United States, almost all of which are utility-scale. 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."
