Wind Turbine Road Setbacks: Ordinances (2022) and Extrapolated Trends, 115 Hub Height 170 Rotor Diameter

Description

This dataset represents wind energy setback requirements from roads based on existing county ordinances as of April 2022. A setback requirement is a minimum distance from a road that an energy project may be developed, and these varied widely across the counties in which they existed. Two versions are provided: one reflecting only the county ordinances and another incorporating extrapolated trends. In the extrapolated version, a median setback equivalent to 1.1 times the turbine tip-height was applied in counties that lacked specific railroad setback regulations. A TIF data file and a PNG map of the data are provided for both versions, showing areas where wind energy is prohibited or permitted across the contiguous United States. The turbine parameters used were a hub-height of 115 meters and a rotor diameter of 170 meters, as obtained from the Annual Technology Baseline (ATB) 2022.

33 In this, the 2023 edition of this report, we present new estimates of the technical potential for land-based wind and solar photovoltaics (PV) for the contiguous United States (CONUS). We also provide cost estimates for the available resources, presenting representative supply curves that can be used in downstream modeling and analysis. Additionally, we introduce new methodologies used to estimate wind capacity, wind energy losses, transmission cost and representation, updated technology cost and design, and scenarios of siting constraints designed to help bound the uncertainty of renewable potential. https://www.nrel.gov/docs/fy24osti/87843.pdf
48 Map of road setbacks existing for wind technology in TIF format. This is the extrapolated version where a median setback equivalent to 1.1 times the turbine tip-height was applied in counties that lacked specific road setback regulations. In the dataset, 0 indicates that wind energy is permitted, while 1 indicates that wind energy is prohibited. Due to size, a GIS software is likely needed to open this file. https://data.openei.org/files/6129/setbacks_road_115hh_170rd_extrapolated.tif
