APS—Cholla Power Plant
APTIM provides power maintenance services to the APS Fossil fleet, including the Cholla Power Plant. Cholla is a major coal-fired power plant near Joseph City, Arizona. The coal burned at the plant came mostly from the McKinley Mine in New Mexico until the mine closed in 2009. APS operates the plant and owns Units 1, 2 and 3, which are capable of producing 615 megawatts of electricity. 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 & gas units. APS is in the midst of decommissioning two Four Corners units where APTIM has scope in other Capital Services business units.
