Arizona Wind Resource Map


The Department of Energy's Wind Program and the National Renewable Energy Laboratory (NREL) recently published a new wind resource map for the state of Arizona. 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, wind power class 4 or higher can be useful for generating wind power with large turbines. Class 4 and above are considered good resources.

This map indicates that Arizona has wind resources consistent with utility-scale production. The larger contiguous areas of good-to-excellent resource are located in northern and eastern Arizona close to the eastern edge of the Mogollon Rim. Good-to-excellent wind resources are also found on the higher rims and ridge crests throughout the state.

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