Empire-Electrical District 5 Double Circuit Upgrade
CX(s) Applied: B1.3
Location(s): Pinal County, Arizona
Office(s): Western Area Power Administration-Desert Southwest Region
Western proposes to replace structures and upgrade to a double circuit 230-kilovolt (kV) transmission line on its Empire-Electrical District #5 115-kV transmission line, within Western's existing right-of-way. This will include the rebuild of 9.2 miles of transmission line, replacing the H-frame structures with steel monopole structures with foundations, hardware and insulator replacement and adding a overhead ground-wire over the entire length of the project. Western will access the structure using crew trucks along the existing access roads. This work is necessary to maintain the safety and reliability of the bulk electrical system.
