APS Completes One of the Largest Transmission Construction Projects in the West

Arizona Public Service completed work on one of the largest transmission construction projects in the west - a 500-kV power line that connects Phoenix to Yuma. The 110-mile transmission line runs from the Hassayampa substation (near the Palo Verde Nuclear Generating Station) to the North Gila substation in Yuma. Called HANG2, the $200 million project is the second route connecting the Valley to Yuma. Construction planning for the HANG2 line began more than a decade ago, as Southwest Arizona's population began to rapidly expand.
