Massachusetts State Wind Resources Map

View larger version View/download a printable PDF version The Department of Energy's Wind Program and the National Renewable Energy Laboratory (NREL) published a new wind resource map for the state of Massachusetts. 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 Massachusetts has wind resources consistent with utility-scale production. Excellent-to-outstanding resource is located on the northern part of Cape Cod and good-to-excellent areas are found in the southern part of Cape Cod and along the shore of Martha's Vineyard and Nantucket. Particular ridge crest locations of the Berkshires in western Massachusetts also have excellent wind resource. Before you plan to install your own wind turbine or wind farm, you must know if the wind resource in your location is adequate. From wind resource maps, you can determine if your area of interest should be further explored. Wind resource at a micro level can vary significantly; therefore, you should get a professional evaluation of your specific area of interest.
