What is NAICS code 221111?

221111 is the U.S. Census Bureau's 2022 NAICS code for Hydroelectric Power Generation, inside the Utilities sector and the Utilities subsector. Federal solicitations carry exactly one NAICS code, and that code is how the buyer classifies the requirement — it decides which size standard applies to the bid and, with it, whether your business counts as small for that contract.

Where is NAICS 221111 work performed?

Tennessee leads of the award records on file for this code, with 1 award. Place of performance is where the work happens, not where the winner is headquartered, so this is the market you would be serving rather than a list of local companies. The full state breakdown is on this page, and each state links to its own award history.

Are there open government bids under NAICS 221111 right now?

Not as of this page load. That is a fact about the feed we track — federal SAM.gov postings plus the state portals we pull — and not a statement that no government anywhere is buying this work today. Join the free alerts and Sam will email you when a solicitation carrying 221111 appears.

Do I have to use NAICS 221111 to bid?

You bid what the solicitation says. The buyer assigns one NAICS code to the requirement, and that code — not the list on your SAM.gov registration — sets the size standard your offer is judged against. Your registration should carry every code you can genuinely perform, because that is what buyers filter on during market research, but adding a code you cannot deliver under does not make you eligible for anything.

Q: What is the SBA size standard for NAICS 221111?

We do not hold a size standard published for these exact six digits, and we will not show you a neighbouring industry's figure in its place — sibling codes in the same NAICS family do not always share a standard, and self-certifying against the wrong one is how a bidder ends up claiming a set-aside they do not qualify for. Look up 221111 directly in 13 CFR 121.201, which lists a threshold for every code.

Q: Who wins NAICS 221111 contracts?

Of the federal contract awards on file under 221111, TENNESSEE VALLEY AUTHORITY holds the largest total: 1 award worth $393,507,089. That is a ranking of this dataset, not of every contractor in the industry, and the table above is capped at the 10 largest by award dollars rather than being the whole field. Those companies are your competition if you bid prime and your customers if you subcontract.

Q: Which agencies buy NAICS 221111?

Department of Energy accounts for the largest total in this dataset: 2 awards worth $393,643,929. Buyers are creatures of habit — the same contracting offices reissue the same requirements on a predictable cycle, so learning one buyer in your code beats chasing every bid in it.

101 federal contract awards on file carry NAICS 221111, worth $556.7M between them. Below: where that work is performed, who has been winning it, which agencies buy it, and the solicitations open under this code right now.

It is the top of the list rather than every contractor in the industry: 10 companies are shown. These are the incumbents: your competition if you bid prime, and worth a call about subcontracting or teaming before you chase a prime award of your own.

Awards are history. These are live: solicitations tagged with this code that still have a deadline ahead of them, soonest first, each carrying the agency's own published record — the buyer, the deadline and the documents. Sam's deep workup, the part that names what disqualifies bidders, is published for specialty-trade construction and janitorial and facilities services, and this industry is not in that scope — so we do not publish one here.

How to use a NAICS code to win government work

Your NAICS code is not paperwork trivia. It is the hinge the whole federal eligibility question turns on: the buyer assigns one code to the requirement, that code sets the SBA size standard the offers are measured against, and the size standard decides whether your business counts as small — and therefore whether you can compete for the set-aside version of the work at all.

Which means the first question is never “can I do this job”. It is “is this contract classified as work I am registered and sized to do”. A firm that can genuinely perform under 221111 but never listed it on its SAM.gov registration is invisible to the market research a contracting officer does before writing the solicitation, which is where most small-business awards are really decided.

Award history under a code tells you the rest. It shows which agencies actually buy this work and where, which contractors have been holding it, and roughly what it pays — before you spend two weeks on a proposal against an incumbent who has held the contract for nine years. A contract with an end date twelve to eighteen months out is a recompete in the making, and the quiet window before it is posted is when a capability statement and a call to the contracting office are worth more than any proposal you could write later.

None of it works if you are not registered. A federal award requires an active SAM.gov registration with a UEI, and the set-aside on a solicitation decides whether your bid is even read. Both are free to sort out, and both are the most common reason a ready contractor is disqualified on a technicality.

Where this page's facts come from

The classification. U.S. Census Bureau 2022 NAICS. Codes, titles and the sector hierarchy are reproduced verbatim from the Census files and cross-checked against a second official Census file. Nothing is paraphrased or shortened.
The size standard. SBA, 13 CFR 121.201. We print a threshold only when it is published for these exact six digits; where it is not, we say so and link the table rather than showing a related industry's figure.
The award figures. Federal prime contract awards published by USAspending.gov, the government's official spending record. Public record, free, no data vendor in between. Grants, loans and direct payments are excluded — they are not work a contractor competes for — and so is state, county and city purchasing.
What is not here. This is a portion of federal contracting under 221111, not all of it. Treat these figures as a floor: the real market is larger than what is on this page.
Missing values. Where USAspending records no amount, agency or recipient, we leave it out instead of filling it in. An award with no reported amount is still counted as an award but enters no total or average, which is why a row's award count can outrun its dollars.
