NAICS 333611 – Turbine and Turbine Generator Set Units Manufacturing covers the design, assembly, and integration of steam, gas, and hydroelectric turbine systems along with their associated generator sets used for power generation in mission-critical applications. This sector produces high-efficiency rotating machinery that converts thermal or kinetic energy into electrical power, often deployed in remote installations, military bases, naval vessels, and federal infrastructure requiring reliable off-grid or backup power. These systems are engineered to meet stringent environmental, safety, and durability standards, and frequently incorporate advanced control systems, redundant cooling, and fuel-flexible combustion technologies. In government contracting, this NAICS supports energy resilience, expeditionary operations, and critical facility continuity programs. Top contractors in this sector include COLORADO STANDBY, LLC and ALLOY SLING CHAINS, LLC, both of which operate as specialized small businesses with niche expertise in turbine system integration, component fabrication, and field servicing. Their presence reflects a competitive landscape dominated by agile, technically focused firms rather than large primes, indicating strong demand for specialized manufacturing and maintenance capabilities tailored to rugged operational environments. The Department of the Interior and the Department of Defense are the primary federal buyers, driving demand through energy independence initiatives, remote facility electrification, and expeditionary power needs for forward operating bases and coastal infrastructure. These agencies prioritize systems that support mission continuity under austere conditions, often requiring ruggedized, low-maintenance turbine-generator units capable of long-duration operation with minimal logistical support. The market is characterized by high technical barriers to entry and a concentration of procurement among contractors with proven experience in military-grade power systems. Opportunities exist for firms with certifications in AS9100, ISO 13485, or defense supply chain compliance, particularly those offering modular, scalable, and fuel-adaptive turbine solutions. Growing emphasis on energy resilience and microgrid integration is increasing demand for turnkey turbine generator packages in both new construction and retrofits.
Small Business Size Standard
The SBA threshold that decides who can bid NAICS 333611 work as a small business.
The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.
13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
