​On Sept. 16, 2011, WAPA cancelled the preparation of the environmental impact statement for the Hualapai Valley Solar Project.  Since the Hualapai Valley Solar LLC interconnection requests are no longer active, WAPA terminated the NEPA review process on its interconnection decision.

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

WAPA was going to prepare an environmental impact statement to address Hualapai Valley Solar’s request to interconnect the proposed project to WAPA’s transmission system and any necessary modifications to WAPA facilities to accommodate the interconnection. The EIS would have also reviewed the potential environmental impacts of constructing, operating and maintaining the proposed project.

The proposed project would have interconnected with WAPA’s transmission system at one of two alternative locations, either the 500-kV Mead-Phoenix Transmission Line or the 345-kV Liberty-Mead Transmission Line.
