APS—West Phoenix Power Plant

APTIM provides power maintenance services to the APS Fossil fleet, including the West Phoenix Power Plant located in southwest Phoenix, Arizona. The West Phoenix Power Plant has seven natural gas-fueled generating units, two combustion turbine units and five units that employ combined-cycle technology. APTIM currently provides fossil plant maintenance services to nine stations within the fleet. A majority of work is performed at Four Corners and Cholla (coal units). The other sites are oil and gas units. APS is in the midst of decommissioning two Four Corners units where APTIM has scope in other Capital Services business units.
