Hualapai Valley Solar, LLC, proposes to construct, operate and maintain a 340-megawatt, solar-powered generating facility in Mohave County, near Kingman, Ariz. The proposed project would use concentrating solar-power-trough technology to capture the sun's heat to make steam, which would power a traditional steam turbine generator. Proposed infrastructure would consist of a solar field, power block, thermal energy storage system, substation site, transmission line, temporary laydown areas and other ancillary facilities.
