Arizona Public Service Company

Arizona Public Service Company, a for-profit subsidiary of Pinnacle West Capital Corporation headquartered in Phoenix, Arizona, is the exclusive provider of electric utility services and energy infrastructure support to federal agencies across central Arizona as prime contractor under a $50 million single-award indefinite delivery contract with the General Services Administration Public Buildings Service Central Office Energy Division (GS00P03BSD0264, running through March 2034). The company operates exclusively as a prime contractor (100% of recent awards) and competes full-and-open with no set-aside designations, reflecting its status as a large utility provider.

APS operates across a highly concentrated federal customer base with 37% of awards concentrated in the top five customer agencies. The General Services Administration Public Buildings Service anchors the relationship with 146 awards as the contracting agency, while end-use agencies are led by the Indian Health Service (12 awards, $31.6 million combined potential value), the National Park Service (10 awards, $17.6 million), and the Federal Bureau of Prisons Federal Correctional Institution Phoenix (17 awards, $15.1 million). Department of Interior Bureau of Indian Affairs offices, Bureau of Indian Education facilities, Bureau of Reclamation sites, and Veterans Health Administration medical centers round out the active agency set. The dollar concentration is stronger than the award count concentration—the top five customer agencies account for approximately 21% of combined potential value—signaling larger average award sizes at Indian Health Service and National Park Service compared to smaller task orders elsewhere.

APS's capability portfolio is narrowly focused on electric utility delivery, energy infrastructure maintenance, and facilities support services grounded in its regulated utility business. Representative recent work includes a $2.6 million delivery order from Indian Health Service for electrical service at Haskell Indian Nations University Center in Polacca, Arizona (FY2025, running through June 2030); a $9.13 million delivery order from Indian Health Service for electrical service at Phoenix Indian Medical Center (FY2024, running through July 2029); a $13.8 million delivery order from GSA for construction task-order services at Grand Canyon National Park (FY2023); and a $2.59 million delivery order from Bureau of Indian Education for electrical service at Tuba City Boarding School (FY2025, running through March 2030). Smaller orders for power line extensions, equipment purchases, transformer delivery, and utility right-of-way clearing round out the service mix. The award portfolio reflects 380 awards classified under PSC utilities-electric and 251 awards under NAICS electric power distribution, with secondary activity in fossil fuel and hydroelectric power generation and building lease/rental services.

APS places the majority of its task orders under three GSA vehicles: Basic Ordering Agreement GS09B96089 (106 task orders, $156 million combined potential value), Indefinite Delivery Contract GS00P03BSD0264 (69 task orders, $38.8 million), and Indefinite Delivery Contract GS00P14BSD1052 (51 task orders, $53.8 million). Activity has grown modestly over the past five years (two awards in 2022 to eleven in 2025) and remains recent with three awards issued in 2026 through October. The recompete cliff is minimal—only three awards totaling $2.8 million potential value complete within the next twenty-four months, meaning the bulk of APS's federal customer relationships carry five- to ten-year completion dates and carry low near-term recompete risk.

Grant-side work is substantial and recent: the Department of Energy awarded APS two large Project Grants under the Grid Infrastructure Deployment and Resilience program (CFDA 81.254) as prime recipient, both effective January 1, 2025 through December 31, 2029. The first is a $60.16 million award for smart grid technology deployment (reclosers, capacitor banks, voltage regulators, sensors) in the Phoenix area to enhance grid reliability and facilitate distributed energy resources integration. The second is a $121.24 million award focused on grid resilience and wildfire-risk reduction across Arizona, with 69% of work designated for rural, tribal, or disadvantaged communities. APS is also a sub-recipient under a Grid Resilience Grant Program subrecipient award from the Arizona Governor's Office (award date December 3, 2025). These grants represent APS's entry into Bipartisan Infrastructure Law-funded federal grid modernization work and signal a strategic pivot beyond utility delivery into infrastructure investment and resilience engineering.

The Service Contract Inventory dataset captures minimal APS activity—one named SCI subcontractor record in FY2025 representing 0.5 FTEs—indicating that APS's federal work is predominantly goods and utility services delivery (exempt from SCI reporting) rather than labor-hour service contracts above the $150,000 threshold. SCI does not reflect the scale of APS's actual federal footprint; the $366.5 million in combined potential value across 591 awards is the appropriate measure of APS's federal presence.
