These direct normal solar radiation maps—filtered by solar resource and land availability—identify the most economically suitable lands available for the deployment of large-scale concentrating solar power plants in the southwestern United States.
Each of the following seven states, as well as the southwestern U.S. region, has two maps: the left and right maps represent analyses excluding land with slopes >1% and >3%, respectively. Lower-resolution jpg versions are available below; much higher-resolution pdf files, suitable for plotting large-scale posters, can be requested.
The index for each map includes three categories of information: power plants by generation type; transmission lines in a range of kilovolts (kV); and direct-normal solar radiation in kilowatt-hours per square meter per day (kWh/m2/d).
NREL has developed these maps to support the Southwest Concentrating Solar Power 1000-MW Initiative. Our Geographic Information Systems (GIS) team assisted with the development of these maps.
