NAICS 221116: Geothermal Electric Power Generation

NAICS 221116 – Geothermal Electric Power Generation covers the production of electricity through the harnessing of heat from the Earth’s subsurface, typically via binary cycle, flash steam, or dry steam power plants. This sector involves the design, construction, operation, and maintenance of geothermal wells, heat exchangers, turbines, and transmission infrastructure to convert geothermal energy into grid-ready electrical power. As part of the federal government’s broader clean energy and sustainability initiatives, geothermal generation supports climate resilience goals, energy security, and decarbonization efforts—particularly in regions with high geothermal gradients such as the western United States. It is a niche but strategically important component of the renewable energy portfolio, often integrated into military base energy resilience programs and federal land management energy projects. No contractor data is available for this NAICS code, indicating limited public procurement activity or a highly fragmented contractor base. Companies operating in this space are typically specialized energy developers, engineering firms with geothermal expertise, or small businesses with proprietary wellfield or binary plant technologies. Large primes are rarely direct performers here due to the project-specific and geographically constrained nature of geothermal development. No agency data is available, suggesting that procurement is either infrequent, consolidated under broader energy or environmental contracts, or managed through non-competitive mechanisms such as interagency agreements or Department of Energy research programs. The competitive landscape is sparse but offers opportunities for niche contractors with proven geothermal engineering capabilities, particularly those capable of supporting DOE-funded demonstration projects or serving federal facilities in high-potential regions. Procurement trends indicate a preference for long-term operational support contracts over capital construction, with growing interest in hybrid systems and enhanced geothermal technologies.
