Golden Valley 230 kV
Increased electrical system reliability
UniSource Energy Services is developing plans for a new double-circuit 230 kilovolt (kV) transmission line that will connect the Harris Substation to the new Mineral Park Substation in Mohave County. The new line would help improve reliability, replace aging equipment and accommodate a projected 5-35 megawatt (MW) increase in customer energy needs over the next decade in the north Golden Valley area. Power within UniSource's Mohave County service territory is transmitted primarily over a 69kV transmission network.
