The Rio Grande River north of Albuquerque, New Mexico. In the majority of western US regions, freshwater availability is a challenging factor for developing new power plants. In some basins, surface and/or groundwater may be available through permitting with the state water-management agency, alternatively water might be purchased and transferred out of its current use to another, or nontraditional water sources can be captured and treated (e.g., wastewater). The relative availability and cost of [...]
