The Department of Energy's Wind Program and the National Renewable Energy Laboratory (NREL) published a new wind resource map for the state of Virginia . 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 Virginia has wind resources consistent with utility-scale production. Several areas of the state are estimated to have good-to-excellent wind resource. These include the Atlantic coast along the Delmarva Peninsula and the Virginia Beach area, the ridge crests in the north-central part of the state, and ridge crests near the borders of West Virginia and North Carolina.
Note: Wind resource at a micro level can vary significantly; therefore, you should get a professional evaluation of your specific area of interest.
