NAICS 221118: Other Electric Power Generation

NAICS 221118

NAICS 221118 – Other Electric Power Generation covers the production of electricity using technologies not classified under conventional thermal, hydroelectric, or nuclear generation. This includes emerging and niche power generation systems such as geothermal, solar thermal, biomass combustion, wind energy, tidal and wave power, and other renewable or alternative energy sources that fall outside standard classifications.

NAICS 221118 – Other Electric Power Generation covers the production of electricity using technologies not classified under conventional thermal, hydroelectric, or nuclear generation. This includes emerging and niche power generation systems such as geothermal, solar thermal, biomass combustion, wind energy, tidal and wave power, and other renewable or alternative energy sources that fall outside standard classifications. These systems are often deployed in remote, off-grid, or specialized federal installations where grid connectivity is limited or reliability must be enhanced through distributed energy resources. In the federal contracting landscape, this NAICS supports mission-critical energy resilience, sustainability goals, and compliance with executive orders on renewable energy adoption across defense, civilian, and federal facility portfolios. No contractor data is available for this NAICS code, indicating a fragmented or nascent contractor base with no dominant primes or large-scale contractors emerging from current procurement records. The sector likely includes small businesses, specialty engineering firms, and niche technology providers focused on decentralized generation systems, often partnering with larger integrators on broader energy infrastructure projects. No agency data is available, suggesting that procurement activity is diffuse across multiple departments, including the Department of Defense, Department of Energy, General Services Administration, and U.S. Army Corps of Engineers, each pursuing localized energy independence, microgrid development, or environmental compliance initiatives without concentrated spending patterns. The competitive landscape is characterized by low concentration and high technical specialization, presenting opportunities for innovators with expertise in distributed energy resources, energy storage integration, and microgrid control systems. Procurement trends indicate growing interest in resilience-focused, low-carbon generation solutions, particularly for military bases and remote federal facilities, though contract volume remains uneven and project-driven rather than programmatic.

Small business size standard

The SBA threshold that decides who can bid NAICS 221118 work as a small business.

SBA threshold
650 employees
Applies to the whole industry code

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.
