,This map illustrates the variety of median project capacity sizes across the United States and California counties for wind projects whose total nameplate capacity is greater than or equal to 1 MW. The absence of projects in the southeastern United States is attributable to low average wind speeds (United States - Annual Average Wind Speed, AWS Truepower and National Renewable Energy Lab). Hurricane strength winds are not usable with current technology. Median project capacity is a function of the statewide capacity and the number of projects within the defined area.

For more information, contact John Hingtgen at John.hingtgen@energy.ca.gov. The map illustrates the variation in median plant capacity across the United States and California of wind plants with nameplate capacity of at least 1 MW. Median plant capacity depends on the statewide capacity and the number of plants 0 60 120 240 Miles within the defined area.,

Power plants with capacity of at least 1 MW are included in totals. Counties shaded in grey have no utility-scale renewable electric capacity. Distributed generation such as rooftop solar, is not included. Data is classified using Jenks Natural Breaks Method. Projection is WGS 1984 California *Teale Albers (US Feet). Data sources are the California Energy Commission's Quarterly Fuel and Energy Report and the Wind Generation Reporting System databases. Data provided is for the year 2023 an dis current as of June 20, 2024. For further inquiries contact John Hingtgen at john.hingtgen@energy.ca.gov.

Areas with high potential for utility-grade wind power were based on wind energy adjusted to 80 m and excluding protected areas and land-cover types unsuitable for wind installations (Elliot et. al. 1986, NREL 2010). Data were originally in classes, 3-7, but were assigned 1/0 values for this dataset, and then averaged to create a 10 km2 grid. See citations for details on raw data. Elliot, D. L., C. G.
