Sentinel Power Services, LLC

Sentinel Power Services, LLC, a for-profit limited liability company headquartered in Carefree, Arizona, provides site survey, design, and installation services for power infrastructure modernization at Federal Aviation Administration facilities as a prime contractor across a single dominant master contract vehicle — the $631.7 million Power Systems Installation Services IDIQ awarded by the FAA in October 2021 with a ceiling through October 31, 2026. Sentinel competes exclusively on full-and-open (non-set-aside) basis and is a 100% prime contractor with no subcontract footprint in the source data.

Sentinel's federal work centers on concrete power systems capabilities: emergency generator installation and replacement (20 kilowatt to 200-kilowatt units), diesel and propane fuel storage tank systems (250-gallon minimum with integrated fuel monitoring), uninterruptible power supply systems (10 kilovolt-amperes and above), underground electrical distribution cabling, electrical remote monitoring systems, and lightning protection infrastructure. Recent representative work includes a $12.1 million delivery order for site-specific fuel system upgrade and storage tank replacement at Middleton Island, Alaska (with removal and installation of five 15,000-gallon aboveground storage tanks, two 80-kilowatt generator sets, remote fill lines, and fuel system reconfiguration, completion July 2026); a $513,856 order for complete power system replacement at Barter Island, Alaska (site survey, design, and installation, September 2026); a $648,404 delivery order for Low Power Ground Based Surveillance construction at Pico del Este and Aguadilla, Puerto Rico radar sites (August 2025); and numerous smaller design-only and site-survey engagements under $50,000. Work spans site survey and engineering reports, design funding, and full installation with change orders for scope adjustments and field conditions across air traffic control towers, approach control facilities, air route surveillance radar installations, terminal Doppler weather radar sites, remote communication facilities, and navigational aid stations.

Customer concentration is absolute: the Federal Aviation Administration accounts for 100% of the 290 awards in the source data. The top three named contracting entities within FAA are FAA Headquarters (169 awards, $697.2 million combined potential value), FAA Aeronautical Center (84 awards, $40.2 million), and FAA Franchise Acquisition Services (29 awards, $56.8 million). A single Department of Defense contract (DOD Washington Headquarters Service, $373 thousand) represents one outlier award. Sentinel places nearly all task orders under two parent vehicles: the Power Systems Installation Services IDIQ (154 task orders, $56.7 million combined potential value) and the related Indefinite Delivery Contract DTFAAC16D00017 (132 task orders, $72 million combined potential value). Both are FAA vehicles through October 2026.

Activity has been substantial and sustained. In 2022, Sentinel received 56 awards; 2023 saw 36; 2024 delivered 52; 2025 and 2026 are tracking low at 7 and 3 awards respectively as of May 2026 — a normal mid-year snapshot for the most recent partial-year data. Over the full portfolio, 16 percent of the $798.8 million combined potential value has been obligated ($125.1 million). Thirteen awards with completion dates in the next twenty-four months carry combined potential value of $16.4 million and face recompete exposure. Sentinel's NAICS footprint is dominated by Electrical Contractors and Other Wiring Installation Contractors (288 awards), with PSC codes split between Installation of Equipment—Electrical and Electronic Equipment Components (153 awards) and Installation of Equipment—Electric Wire and Power Distribution Equipment (133 awards).

Place of performance spans the continental United States, Alaska, Hawaii, Puerto Rico, Guam, and Pacific territories (Chuuk, Pohnpei, Majuro, Grand Turk). Work is performed across FAA's national network with administrative and technical oversight rooted in the FAA's Franchise Acquisition Services organization. Funding sources include Infrastructure Investment and Jobs Act, Bipartisan Infrastructure Law appropriations, and standard FAA budget allocations. Delivery orders are uniformly firm-fixed-price and non-set-aside at task order level, with ultimate completions extending through October 2026, and Sentinel's portfolio demonstrates consistent multi-year engagement in federal power infrastructure modernization supporting the FAA's critical mission to maintain uninterrupted air traffic control and navigation operations nationwide.
