APS—Yucca Power Plant
APTIM provides power maintenance services to the Yucca Power Plant, a natural gas-fueled plant near Yuma in southwestern Arizona. The Yucca Power Plant has six combustion turbine units that produce 233 MW, which are owned and operated by APS; one 75 MW steam turbine and one 22 MW combustion turbine, both of which are owned by the Imperial Irrigation District but operated by APS. 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.
