Wind Resource Potential

State Wind Resource Potential Tables

Find state wind resource potential tables in three versions: Microsoft Excel 2007, 2003, and Adobe Acrobat PDF.

30% Capacity Factor at 80-Meters

Additional 80- and 100-Meter Wind Resource Potential Tables

The National Renewable Energy Laboratory (NREL) estimated the windy land area and wind energy potential for each state using AWS Truepower's gross capacity factor data. This provides the most up to date estimate of how wind energy can support state and national energy needs.

The table lists the estimates of windy land area with a gross capacity of 30% and greater at an 80-meter (m) height and the wind energy potential from development of the "available" windy land area after exclusions.

"Installed capacity" refers to the potential megawatts of rated capacity that could be installed on the available windy land area, and "annual generation" is the estimated annual wind energy generation in gigawatt-hours that could be produced from the installed capacity. NREL reduced the wind potential estimates by excluding areas unlikely to be developed, such as wilderness areas, parks, urban areas, and water features (see Wind Resource Exclusion Table for more detail). Additional wind potential tables are included for 80-m and 100-m heights and various capacity factor ranges.

NREL produced charts showing the wind resource potential above a given gross capacity factor at both 80-m and 100-m heights. Below are two wind potential chart for the United States; one is for the 48 contiguous states. Additional wind potential charts are included for each state.
