NAICS 221118: Other Electric Power Generation

This U.S. industry comprises establishments primarily engaged in operating electric power generation facilities (except hydroelectric, fossil fuel, nuclear, solar, wind, geothermal, biomass). These facilities convert other forms of energy, such as tidal power, into electric energy. The electric energy produced in these establishments is provided to electric power transmission systems or to electric power distribution systems. Cross-References.

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.

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.

Modular Power Generation and Distribution
Solicitation # CEHNC-031467-OT
The U.S. Army Corps of Engineers, Huntsville Center (CEHNC) is soliciting white papers under Other Transactional Authority 10 USC 4022(f) for the procurement of relocatable Modular Power Generation and Distribution solutions. This initiative supports the Department of War by providing standardized, factory-integrated, turnkey power systems for 10 to 12 sites across the United States. The primary objective is to implement solutions capable of stabilizing large transient loads, with technical requirements specifying voltage regulation within +/-2 percent under full load and the ability to stabilize voltage and frequency within 6 seconds during load-switching events. The total estimated aggregate value of the program is 1.2 billion dollars, with individual prototype awards expected to range between 55 million and 100 million dollars. This is a two-step acquisition process beginning with the submission of white papers by September 25, 2026, which may lead to a Request for Prototype Proposal. The final solutions must be fully implemented by February 28, 2028. Awards will be based on best value and utilize a Firm Fixed Price Milestones agreement structure. To be eligible, projects must include significant participation by a nonprofit research institution or nontraditional defense contractor, and all significant participants other than the government must be small business concerns. Additionally, at least one-third of the total prototype project cost must be funded by non-federal parties. All proposed solutions must comply with the Buy American Act and meet specific MIL-STD controls for SCADA systems.

Powering Affordable Reliable Technology (PART) Energy Program
Solicitation # RUS-PART-2026
The Powering Affordable Reliable Technology (PART) Energy Program, administered by the Rural Utilities Service (RUS) under the USDA, is soliciting Letters of Interest (LOI) for loan applications to finance renewable energy resource (RER) systems and supporting energy storage systems (ESS). Funded by approximately $410 million in budget authority from the Inflation Reduction Act of 2022, the program provides individual awards ranging from $1 million to $100 million. Qualified projects may receive loan forgiveness of up to 40 percent, provided they demonstrate tangible benefits to ratepayers in the service area. Project loans generally finance up to 75 percent of capitalized costs, requiring a 25 percent cash or equity match, though system loans may cover up to 100 percent of costs. Eligible entities must submit their LOIs via Grants.gov between September 8, 2026, and October 9, 2026. Submissions must include the SF-424 form, a completed LOI PDF, project shapefiles, and three years of financial statements. LOIs are evaluated on a rolling basis based on applicant and project eligibility, technical feasibility, and financial status. Successful LOI submitters who receive an invitation to proceed must submit a full application within 60 days, including detailed engineering reports, interconnection agreements, and environmental clearances. All projects must comply with the Build America, Buy America Act, maintain active SAM registration, and implement a cybersecurity risk mitigation plan. The performance period extends five years from environmental clearance, with a final deadline for all fund advances by September 30, 2031.
