Sentinel Power Services, LLC

Sentinel Power Services, LLC, a for-profit limited liability company based in Carefree, Arizona, delivers site survey, engineering design, and installation services for emergency power infrastructure—generators, fuel storage tanks, uninterruptible power supply systems, and electrical distribution equipment—to the Federal Aviation Administration as a prime contractor on a $631.7 million indefinite-delivery/indefinite-quantity contract awarded in October 2021 with no socioeconomic set-aside.

Sentinel competes exclusively in full-and-open procurements and does not hold SBA certifications; 100% of its recent award footprint is prime work, predominantly under the FAA's Power Systems Installation Services IDIQ established October 26, 2021. The vendor's customer base is entirely FAA, with oversight split across three organizational units: FAA Headquarters (168 awards, $695.3 million combined potential value), FAA Franchise Acquisition Services (31 awards, $60 million), and FAA Aeronautical Center (84 awards, $40.2 million). The concentration is extreme—the top customer accounts for roughly 87% of combined potential value—reflecting Sentinel's exclusive reliance on a single federal customer and parent vehicle. Work spans the continental United States, Alaska, Hawaii, Puerto Rico, Guam, and Pacific territories including Chuuk, Pohnpei, and Majuro.

Sentinel's recent capability footprint centers on emergency generator installation (20–200 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, and lightning protection infrastructure at air traffic control towers, approach control facilities, radar installations, terminal Doppler weather radar sites, remote communication facilities, and navigational aid stations. Representative recent work includes a $12.3 million order for constructability review and fuel system replacement at Middleton Island, Alaska (five 15,000-gallon aboveground storage tanks, two 80-kilowatt generator sets, remote fill lines, and fuel system reconfiguration, completion October 2026); a $513,856 delivery order for complete power system replacement at Barter Island, Alaska (site survey, design, and installation, completion September 2026); a $464,619 order for outdoor emergency generator installation at JFK International Airport's Terminal Doppler Weather Radar facility in Brooklyn, New York (completion June 2026); and a $705,602 delivery order for emergency generator and fuel storage system modernization at Springfield-Branson National Airport in Missouri (completion August 2026).

Activity has grown from 7 awards in 2025 to 56 in 2022 (reflecting the IDIQ award cycle), with moderate output in 2023–2024 (36 and 52 awards) before declining sharply to 7 awards in 2025 and 4 in 2026. The recompete exposure is modest: 16 awards with ultimate completion dates in the next twenty-four months carry combined potential value of $17.6 million. Combined potential value across all awards stands at $800.1 million; obligated funds total $126.4 million (16% of potential value), indicating significant unfunded future work. Sentinel holds no subcontractor relationships in the source material; all work is performed as prime. The vendor's primary NAICS designation is 238210 (Electrical Contractors and Other Wiring Installation Contractors), with PSC codes concentrated in equipment installation for electrical and electronic components and power distribution. All delivery orders under the IDIQ are firm-fixed-price, non-set-aside awards issued without socioeconomic restrictions, indicating Sentinel's competitive posture in the civilian federal power infrastructure market is based entirely on technical capability and price rather than small-business or other preferential status.
