Arizona Public Service Company

Arizona Public Service Company, a subsidiary of Pinnacle West Capital Corporation headquartered in Phoenix, Arizona, supplies electric utility services, energy management solutions, and electrical infrastructure support to federal civilian agencies as a prime contractor on a full-and-open basis with no set-aside designations. APS competes as a large, for-profit utility provider delivering electricity, system repairs, power line extensions, infrastructure design, and equipment purchases across central Arizona federal facilities.

APS holds a single-award indefinite delivery contract (GS00P03BSD0264) valued at $50 million through March 2034 with the General Services Administration Public Buildings Service Central Office Energy Division, from which the majority of task orders flow. This IDV enables federal agencies to procure electric utility and energy management services throughout central Arizona, including at National Park Service sites, Bureau of Indian Affairs offices, Bureau of Land Management lands, Veterans Health Administration medical centers, Indian Health Service clinics, and Bureau of Prisons correctional institutions. Recent representative prime work includes a $10 million delivery order from the Indian Health Service for electrical services at the Phoenix Indian Medical Center (awarded July 2024, ultimate completion July 2029); a $13.8 million delivery order from GSA for construction task order services at Grand Canyon National Park (awarded May 2023, ultimate completion August 2024); a $2.6 million delivery order from the Indian Health Service for electrical service at Haskell Indian Nations University Center in Polacca, Arizona (awarded June 2025, ultimate completion June 2030); and a $2.3 million delivery order from the Bureau of Indian Education for electrical services at Tuba City Boarding School (awarded March 2025, ultimate completion March 2030).

APS also received two significant federal grant awards in 2025 from the Department of Energy under the Grid Infrastructure Deployment and Resilience program (CFDA 81.254): a $121.2 million Project Grant for wildfire resilience enhancement across Arizona's grid with 69% of work in rural, tribal, or disadvantaged communities (through December 2029), and a $60.2 million Project Grant for smart grid technology deployment in the Phoenix area (through December 2029). The vendor serves 43 distinct customer agencies. The Indian Health Service leads by potential value ($32.4 million across 12 awards), followed by the National Park Service National Office ($17.6 million, 10 awards) and the Bureau of Prisons Federal Correctional Institution Phoenix ($15.1 million, 16 awards). By award count, the GSA Public Buildings Service dominates with 146 awards, representing 37% of the portfolio; the Department of the Army, Department of the Interior Bureau of Indian Affairs Navajo Region, and Bureau of Prisons round out the top tier. APS operates three additional parent vehicles: Basic Ordering Agreement GS09B96089 (106 task orders, $156 million combined potential value), Indefinite Delivery Contract GS00P14BSD1052 (51 task orders, $53.8 million combined potential value), and Blanket Purchase Agreement V649P2445 (18 task orders, $2.3 million combined potential value). Recent activity shows growth—from two awards in 2022 to eleven in 2025—with only four awards (combined potential value $4.4 million) completing within the next twenty-four months, indicating minimal near-term recompete exposure. APS also serves as a sub-recipient on a Grid Resilience Grant Program award from the Executive Office of State of Arizona (subrecipient awarded December 2025). The vendor's federal footprint concentrates in electric power distribution (250 awards) and fossil fuel electric power generation (118 awards) under PSC Utilities-Electric (379 awards).
