The Department of Energy's Wind Program and the National Renewable Energy Laboratory (NREL) published a wind resource map for the state of Indiana. This resource map shows wind speed estimates at 50 meters above the ground. 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).
This map shows the highest wind resources in Indiana are found across the northern half of the state. Class 3 areas are located across the north-central region of Indiana with the largest contiguous area being northwest of Lafayette and northwest of Indianapolis. Other Class 3 areas are located east of Muncie. 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 be suitable for utility-scale wind development.
Note: Wind resource at a micro level can vary significantly; therefore, you should get a professional evaluation of your specific area of interest.
