Golden Valley 230 kV

Increased electrical system reliability

UniSource Energy Services, is planning to build a new 230-kilovolt (kV) transmission line and substation in Mohave County near Kingman and the Golden Valley area. The Golden Valley 230kV Transmission Line Project will improve service reliability by replacing aging equipment and provide greater electric capacity to accommodate a projected 5-35 megawatt (MW) increase in peak energy demand over the next decade in the area.

National Environmental Policy Act (NEPA) Process

The Bureau of Land Management (BLM), acting as lead federal agency, prepared an environmental assessment (EA) for the Golden Valley 230kV Transmission Line Project as required by the National Environmental Policy Act (NEPA).

Six route alternatives were identified through an extensive public outreach process initiated in 2007 that included input from area residents, landowners, business owners and government agencies. The EA identifies Alternative E1 as the BLM’s preferred alternative.
