Solar Turbines Incorporated

Solar Turbines Incorporated, a subsidiary of Caterpillar Inc. based in San Diego, California, manufactures gas turbine generators and delivers maintenance, repair, and related support services to federal agencies as a prime contractor exclusively — the vendor holds no subcontract awards in the source data. The company competes in full-and-open federal markets without SBA set-aside designations across all recent awards.

Solar Turbines' federal footprint spans 696 total awards with a combined potential value of $52.3 million, though obligated funding of $230.3 million indicates significant work completion across a long contract history (first award 1981). The company serves 36 distinct customer agencies, with recent activity concentrated among Navy and Air Force customers. The top five customers by award count — the Department of the Air Force (121 awards), the Department of the Navy (120 awards), the Department of the Army (77 awards), the Department of Homeland Security US Coast Guard (43 awards), and the Naval Supply Systems Command (41 awards) — account for 58% of all awards. By potential value, however, concentration shifts: the GSA Public Buildings Service National Capital Region leads with 9 awards and $16.1 million combined potential value, followed by the Naval Facilities Engineering Command (19 awards, $11.9 million) and the Social Security Administration (9 awards, $8.8 million), which together represent 80% of combined potential value.

Core capability focus is turbine and generator manufacturing, maintenance, and repair. Recent representative work includes a $5.13 million Definitive Contract with the National Capital Region (awarded September 2025, running through March 2030) for gas turbine generator maintenance serving federal facilities in the Washington, DC area; a $4.39 million Definitive Contract with Naval Medical Center San Diego for cogeneration system maintenance through January 2027; a $1.85 million Social Security Administration Definitive Contract for maintenance and repair of Titan 130 gas turbine generator sets through November 2027; a $198,372 base-year USDA Agricultural Research Service Purchase Order for Solar Taurus 3500 kilowatt turbine service and maintenance at Ames, Iowa (with four one-year options totaling up to $991,860); and a $306,792 delivery order from Navy Installations Command (May 2026) for recurring solar turbine generator maintenance at Indian Head, Maryland through May 2027. The vendor also performs facility support work — a $1.41 million Naval Facilities Engineering Command delivery order (July 2025) for secured buildings janitorial services at Bowie, Maryland, and earlier electric inspection and emergency turbine support orders across naval installations.

The vendor's primary contract vehicles are five Basic Ordering Agreements and two Indefinite Delivery Contracts. The largest vehicle is Basic Ordering Agreement F0460683G0026 with 37 task orders, followed by an IDC with the Navy (N0010403GA110, 35 task orders, $975 thousand combined potential value) and a second BOA (F0460684G1053) with 20 task orders. An IDC with the Navy (N6247204D6003) carries 15 task orders and $1 million combined potential value.

Work is performed across multiple domestic locations, including naval installations at Dahlgren and Bowie, Maryland; Indian Head, Maryland; USDA facilities in Ames, Iowa; Naval Medical Center San Diego; and the National Capital Region. The NAICS and PSC profiles reinforce the turbine and generator focus: top NAICS categories are Turbine and Turbine Generator Set Units Manufacturing (104 awards), Other Electronic and Precision Equipment Repair and Maintenance (41 awards), and Speed Changer and Gear Manufacturing (36 awards); top PSC codes center on Gas Turbines and Jet Engines (141 awards), Generators and Generator Sets (58 awards), and Engine Fuel System Components (45 awards).

Recent activity has declined — nine awards in 2022 falling to one in 2024 and four in 2025, with just one award in 2026 to date. Only three awards with combined potential value of $6.5 million face ultimate completion within the next twenty-four months, representing modest recompete exposure in that window. Across SCI-reportable service contracts above the $150,000 threshold, Solar Turbines invoiced $3.9 million over FY2023–FY2025 (FY2023: $1.4 million; FY2024: $1.3 million; FY2025: $1.2 million) and delivered roughly 0.6 FTEs in FY2025. Government-paid hourly rates on SCI contracts run a median of $1,598.33 per hour, with senior labor pricing extending to $1,934.69 per hour and entry rates around $944.20 per hour. The vendor performs all work with internal staff — zero sub-hours share across SCI prime contracts — and operates as a pure prime with no subcontract work in the source data.
