The U.S. Department of Energy's (Energy Department's) Wind Program and the National Renewable Energy Laboratory published a 50-meter height wind resource map for South Dakota. This map is a key piece of understanding the state's wind resource potential from a development, policy, and a jobs and economic development impact perspective.

About the 50-Meter South Dakota Wind Resource Map

This resource map shows estimates of wind power density at 50 m above the ground and depicts the resource that could be used for community-scale wind development using wind turbines at 50-60-m hub heights.

As a renewable resource, wind was classified according to wind power classes, which were based on wind speed frequency distributions and air density. These classes ranged from Class 1 (the lowest) to Class 7 (the highest). In general, at a 50-m height, wind power Class 4 or higher could have been useful for generating wind power with turbines in the 250-kW to 750-kW rating. Given the advances in technology, resources below Class 4 may now be suitable for the new midsize wind turbines. In recognition of these continuing advancements in wind energy technologies and the ability for the current generation of wind turbines to extract cost competitive wind energy from lower wind speeds the Energy Department has moved away from the wind power classification system and now reports wind speeds only.

This map indicates that South Dakota has wind resources consistent with community-scale production. Good-to-excellent wind resource areas are located throughout the state. Prominent excellent-to-outstanding resource areas are located on the hills east of Pierre, the ridges in south-central South Dakota near the Nebraska border, and hills near Rapid City. Ridge crest locations in the Black Hills can also have excellent wind resource.

Note: Wind resource at a micro level can vary significantly; therefore, you should get a professional evaluation of your specific area of interest.
