The Department of Energy's Wind Program and the National Renewable Energy Laboratory (NREL) published a wind resource map for the state of Nebraska. This resource map shows wind speed estimates at 50 meters above the ground and depicts the resource that could be used for utility-scale wind development. Future plans are to provide wind speed estimates at 30 meters, which are useful for identifying small wind turbine opportunities.
As a renewable resource, wind is classified according to wind power classes, which are based on typical wind speeds. These classes range from Class 1 (the lowest) to Class 7 (the highest). In general, at 50 meters, wind power Class 4 or higher can be useful for generating wind power with large turbines. Class 4 and above are considered good resources. Particular locations in the Class 3 areas could have higher wind power class values at 80 meters than shown on the 50-meter map because of possible high wind shear. Given the advances in technology, a number of locations in the Class 3 areas may suitable for utility-scale wind development.
This map indicates that Nebraska has wind resources consistent with utility-scale production. Major areas of good wind resource are found throughout much of Nebraska except the extreme eastern fringe (such as Lincoln eastward to the Missouri River). Transmission lines either traverse or are located in close proximity to many of these good wind resource areas. Significant areas of excellent wind resource are imbedded within some of the good wind resource areas, such as the excellent areas located southwest of Norfolk, west of Valentine, west of Chadron, and south of Scottsbluff. The best wind resource areas are typically located on elevated terrain features, whereas the lowest wind resource are generally located in valleys and basins with relatively low elevations.
Note: Wind resource at a micro level can vary significantly; therefore, you should get a professional evaluation of your specific area of interest.
