Quartzsite Solar Energy Project

Quartzsite Solar Energy, LLC proposes to construct a 100-MW (net), solar-powered electrical generation facility in La Paz County, Ariz. The proposed Project would be located approximately six miles north of Quartzsite, and adjacent to Arizona State Route 95. The proposed Project, powerline and ancillary facilities would be on BLM administered land.

The proposed project would use concentrating solar “power tower” technology to capture the sun’s heat to make steam, which would power traditional steam turbine generators. The solar power facility would contain the power block, a central receiver or tower, solar fields which consist of mirrors or heliostats to reflect the sun’s energy to the central tower, a thermal energy storage system, technical and non-technical buildings, a stormwater system, water supply and treatment systems, a wastewater system, and other supporting facilities.

QSE has applied to Western to interconnect the proposed Project to Western’s transmission system. The transmission line from the solar facility would extend approximately 0.5 miles from the solar facility boundary to a new substation to be constructed adjacent to Western’s existing line. The substation would be owned, operated, and maintained by Western, and would be located adjacent to Western’s existing Bouse-Kofa 161-kV line that parallels State Route 95 in the vicinity of Quartzsite, Ariz.

Western will prepare an environmental impact statement to address Western’s Federal action of interconnecting the proposed Project to Western’s transmission system and making any necessary modification to Western facilities to accommodate the interconnection. The EIS will also review the potential environmental impacts of QSE constructing, operating, and maintaining the proposed project. The Bureau of Land Management will serve as a cooperating agency during preparation of the EIS.
