NAICS 221114 – Solar Electric Power Generation encompasses the design, construction, operation, and maintenance of utility-scale and distributed photovoltaic (PV) systems that convert sunlight directly into electricity for grid interconnection or on-site consumption. This sector includes solar array installation, inverters, tracking systems, energy storage integration, grid interconnection studies, and performance monitoring solutions. In the federal contracting landscape, this NAICS supports energy resilience, sustainability mandates, and renewable energy goals under executive orders and agency net-zero initiatives. Projects often involve complex engineering, environmental permitting, and compliance with Federal Energy Management Program (FEMP) standards, making it a specialized niche within the broader clean energy procurement ecosystem. No contractor data is available for this NAICS code based on current government contracting records. The Department of State is the primary federal agency awarding contracts under this NAICS code, primarily to support energy security and diplomatic infrastructure modernization at overseas facilities. These procurements typically fund solar microgrids, rooftop PV systems, and off-grid power solutions for embassies and consulates in remote or high-cost energy locations, aligning with the Department’s Global Climate Strategy and Foreign Assistance priorities. The competitive landscape for solar electric power generation in federal contracting is characterized by a small but highly specialized pool of contractors, often consisting of renewable energy developers, engineering firms with energy infrastructure expertise, and small businesses with niche certifications in federal solar procurement. Demand is driven by long-term power purchase agreements (PPAs), energy savings performance contracts (ESPCs), and mission-critical energy independence initiatives. Opportunities are concentrated in projects requiring compliance with federal sustainability frameworks and integration with existing utility infrastructure, presenting a steady, if selective, pipeline for qualified contractors with proven experience in federal energy projects.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 221114 work as a small business.

500 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.

C--REC Purchase Order Award
Solicitation # 1305M426Q0047
The National Oceanic and Atmospheric Administration (NOAA), through its Office of Chief Administration and Safety and Environmental Compliance Office, is soliciting 10,409 MWh of Renewable Energy Certificates (RECs) to meet federal sustainability mandates for carbon pollution-free electricity under Section 203 of the Energy Policy Act of 2005. The RECs must be Green-e certified or equivalent, generated from eligible U.S.-based renewable resources such as wind or solar, with commercial operation dates on or after January 1, 2011, and must be tracked and retired in recognized U.S. registries like WREGIS, M-RETS, NEPOOL-GIS, GATS, or NAR. The certificates must originate from facilities operating between April 1, 2025, and January 1, 2027, to qualify for FY 2026 vintage compliance. The solicitation, issued under FAR Part 12 as a combined synopsis/solicitation, is an entirely small business set-aside under NAICS codes 221114 and 221115, each with a 500-employee size standard. Offerors must be registered in SAM.gov with a valid UEI, provide a signed attestation confirming exclusive ownership and no double-counting of RECs, and comply with FAR 52.219-14’s limitation on subcontracting, which restricts non-small business subcontracting to no more than 50% of contract value. The award will be made under the Lowest Price Technically Acceptable (LPTA) method, where technical compliance is a pass/fail threshold and price determines selection among qualified responders. Delivery is FOB destination to NOAA’s facilities in Silver Spring, Maryland, with final acceptance requiring submission of facility metadata including name, commercial operation date, and NERC region. Payment must be requested via the Invoice Processing Platform (IPP) exclusively. Security requirements mandate that personnel complete either NACI or SAC clearance based on contract duration and type, and non-U.S. citizens must meet specific residency and immigration criteria. An organizational conflict of interest clause requires full disclosure of prior or ongoing work related to the acquisition, with potential disqualification from future procurements if unmitigated conflicts exist. No physical packaging, labeling, or barcoding requirements apply due to the digital nature of RECs, and attachments are intentionally omitted. The solicitation closed on July 31,
