Golden Valley 230 kV

Increased electrical system reliability

UniSource Energy Services (UES) has a need to develop a double-circuit 230kV transmission line from the Harris Substation to the new Mineral Park Substation to improve reliability, replace aged equipment, and accommodate a projected 5 to 35 megawatt (MW) increase in load over the next decade in the north Golden Valley area. Power within the UES Mohave service territory is transmitted primarily over a 69kV transmission network.
