Interim Wind Energy Maps

Missouri Interim Wind Maps:

These maps are INTERIM work products of AWS Truewind Solutions, as published by the Missouri DNR in November 2003 and are provided here for those persons interested in comparing the INTERIM map with the FINAL (validated) maps. According to the Final Report from AWS Truewind:

"After reviewing the validation results, NREL recommended moderate adjustments in speed and power one region of the state. The speed was increased by 5% in eastern Missouri in the counties of St. Charles and St. Louis, and the power was increased by about 30%."

For your convenience we have provided a link to the FINAL wind energy maps.

Wind power density maps

The 50-meter wind power density map shows the predicted mean wind power density (amount of wind energy) at 50-meter height in the National Renewable Energy Laboratory's (NREL) standard wind resource classes. The 100-meter wind power density map shows the predicted mean wind power density at 100-meter height. When compared to the 50-meter wind density map, this indicates a substantial increase in wind energy as the distance from the ground increases. To view the INTERIM maps, click on the links below.

Average annual wind speed maps

The wind speed maps show the predicted mean wind speed in Missouri at heights of 30 meters, 50 meters, 70 meters, and 100 meters, respectively, above the effective ground level. A typical tower height for the current generation of large utility-scale wind turbines of 750 KW (kilowatt) to 2 MW (megawatt) rated capacity is 70 meters. A typical height for small turbines of up to 50 KW rated capacity is 30 meters, which is consistent with on-farm or residential use. To view the INTERIM maps, click on the links below.

Note icon.  Please note: The assignment of colors to wind speed in the legend of the INTERIM 30 meter wind speed map differs from the legend used for the other INTERIM maps of wind speed at other distances above ground level. To view the differences in the maps' legends, it is necessary to open the maps provided as PDF files.
