This Wyoming wind-turbine data set represents locations of wind turbines found within Wyoming as of August 1, 2009. Each wind turbine is assigned to a wind farm. For each turbine, this report contains information about the following: potential megawatt output, rotor diameter, hub height, rotor height, land ownership, county, wind farm power capacity, the number of units currently associated with its wind farm, the wind turbine manufacturer and model, the wind farm developer, the owner of the wind farm, the current purchaser of power from the wind farm, the year the wind farm went online, and the status of its operation. Some attributes are estimates based on information that was obtained through the American Wind Energy Association and miscellaneous online reports. The locations are derived from August 2009 true-color aerial photographs made by the National Agriculture Imagery Program; the photographs have a positional accuracy of approximately ±5 meters. The location of wind turbines under construction during the development of this data set will likely be less accurate than the location of turbines already completed. The original purpose for developing the data presented here was to evaluate the effect of wind energy development on seasonal habitat used by greater sage-grouse. Additionally, these data will provide a planning tool for the Wyoming Landscape Conservation Initiative Science Team and for other wildlife- and habitat-related projects underway at the U.S. Geological Survey's Fort Collins Science Center. Specifically, these data will be used to quantify disturbance of the landscape related to wind energy as well as quantifying indirect disturbances to flora and fauna. This data set was developed for the 2010 project "Seasonal predictive habitat models for greater sage-grouse in Wyoming." This project's spatially explicit seasonal distribution models of sage-grouse in Wyoming will provide resource managers with tools for conservation planning. These specific data are being used for assessing the effect of disturbance resulting from wind energy development within Wyoming on sage-grouse populations.

The attributes assigned to the individual wind turbines (with the exception of the wind farm name), are based on estimated individual turbine potential power and charts of associated heights for varying potential power. These are estimates and will not always hold true to what was installed on the ground.
These items were checked for: Unlabeled Features: All features labeled when information available Tests Completed on: 04/06/2010 Description of how tests performed: Entire data set checked for topology errors. All features that needed to be labeled have been verified by examining all records.
Description of Attribute Completeness: All features were labeled but caution should be used when using attributes, because information derived from various sources. Description of Positional Accuracy Completeness: Locations of turbines estimated from heads-up digitizing off NAIP 2005 and NAIP 2009.
Wind turbines locations are based on the best approximated location of the wind turbine's base. This was not always easily accomplished, because some wind turbines were under construction. Estimated accuracy is +/- 5 meters.
Accuracy of heights are possibly not exact because the size of rotors are sometimes customized for a site.
NAIP 2005
NAIP 2009
Spatial data set of land ownership for Wyoming based on 2005 data. This dataset is intented to represent the ownership information on Master Title Plats(MTPs).
Wind turbine locations extracted from NAIP 2005 imagery by zooming into delineated wind farm locations and identifying individual turbines. 2009 NAIP was not available at the time tracking of wind turbines began and therefore, 2005 NAIP was a source data set for some data. These locations were validated after receiving 2009 NAIP in January of 2010.
