FTA's FY2026 Bus NOFO Cuts the Pot From $2 Billion to $610 Million — and Flips the Priority From Zero-Emission to Low-Emission. Applications Close September 21.

The Federal Transit Administration has published its FY2026 notice of funding opportunity for bus capital programs, and the two numbers that matter tell most of the story before you open the document.

$610 million total. Split as $589 million through the Low or No Emission Grant Program under 49 U.S.C. 5339(c) and $21 million through the Buses and Bus Facilities Competitive Program. Proposals are due through Grants.gov by 11:59 p.m. Eastern on September 21, 2026.

Now the comparison. In FY2025, FTA awarded roughly $2 billion across 165 transit projects in 45 states and the District of Columbia. In FY2024, about $1.5 billion across 117 projects in 47 states.

This year's pot is roughly 70 percent smaller than last year's. Every strategic decision in your application should follow from that fact.

The priority reversal is the buried lede

The dollar figure will get the headlines. The sentence that will actually decide awards is a statement of intent in the notice: FTA intends to prioritize low-emission projects over zero-emission projects to the maximum extent permitted by law.

For anyone who has been applying to Low-No since the program's expansion, this is a genuine inversion. The Low or No Emission program has spent several years functioning, in practice, as the federal government's battery-electric and hydrogen fuel cell bus program. Agencies built fleet transition plans around it. Consultants built application templates around it. The unstated assumption in nearly every competitive Low-No application since 2022 has been that a zero-emission propulsion choice was the strongest position on the board.

That assumption is now wrong for this cycle.

Read the statutory frame and the shift becomes legible. Section 5339(c) funds buses using "low or no emission" propulsion — the "low" was always in the statute, covering technologies such as compressed natural gas, propane, hybrid-electric and other propulsion that reduces emissions relative to a conventional diesel baseline without eliminating them. FTA is not rewriting the law. It is exercising discretion within it, and moving that discretion in the opposite direction from the last several competitions.

There is a second provision that reinforces the same tilt. Any zero-emission project, or zero-emission components of a project, must dedicate 5 percent of federal funds to workforce development — unless the applicant certifies that less or no funding is needed for that purpose. That requirement exists to address the real problem that maintaining a battery-electric bus is a different job than maintaining a diesel one. But in a cycle where the pot shrank 70 percent, a mandatory 5 percent carve-out is 5 percent of your requested capital that does not buy a bus.

What this means for the two obvious applicant types

If you are mid-transition to a zero-emission fleet, you are in the harder position, and you should be honest with yourself about it. You are not disqualified — zero-emission projects remain eligible, and FTA's stated priority is an intent applied "to the maximum extent permitted by law," not a prohibition. But you are now competing for a smaller share of a much smaller pot, against a stated agency preference running the other way.

Your strongest available moves:

• Lead with reliability and state of good repair, not with emissions. A zero-emission application framed primarily around climate benefit is writing to last cycle's evaluation criteria. An application framed around replacing buses past their useful life, restoring service reliability, and serving riders who depend on the route is writing to this one.
• Handle the workforce development requirement affirmatively. You must dedicate 5 percent of federal funds to workforce development or certify that less is needed. Do not treat this as a compliance box. A concrete, costed technician training plan — with a named community college or joint apprenticeship partner — turns a mandatory carve-out into evidence that your project will actually keep buses on the road. That is a maintainability argument, and maintainability is where zero-emission applications have historically been weakest in reviewer notes.
• Consider whether a mixed-fleet request scores better than a pure one. An application that requests some low-emission vehicles alongside zero-emission units, with a clear operational rationale for each, sits closer to FTA's stated priority than an all-ZEB request while still advancing your transition.

If you operate a diesel fleet and had written off Low-No, this is your cycle. Hybrid-electric, CNG and propane replacements are now the favored category in a program that has been effectively closed to you by competitive pressure for years. The per-vehicle cost of a low-emission bus is also substantially below a battery-electric one, which means your requested amount buys more buses — and "buses delivered per federal dollar" is a metric that reads well in a constrained year.

The corollary for your application: do not assume the low competition of prior years. A large number of agencies are reading the same notice and reaching the same conclusion. The category that just became favored is also the category about to get crowded.

The math of a 70 percent cut

It is worth sitting with the scale for a moment, because it changes what a realistic ask looks like.

FY2025: roughly $2 billion, 165 projects — an average near $12 million per project. FY2026: $610 million. If FTA funds a similar number of projects, average award size drops to roughly $3.7 million. If it holds average award size near historical levels, it funds around 50 projects instead of 165.

Either way, the implication for your budget request is the same: the oversized ask is the most likely reason a technically sound application loses this year. An agency that requested $25 million in FY2025 and is preparing the same request now is asking for more than 4 percent of the entire national program. That is a hard argument to win.

Scope down. A phased request — fund the first tranche of vehicles now, with a clear plan for subsequent phases — is more fundable than an all-or-nothing capital package, and it gives the reviewer an obvious way to say yes.

The $21 million Buses and Bus Facilities line deserves specific mention because its scarcity is easy to miss. That is a genuinely small national number for a program covering bus purchases, rehabilitation and facility construction. Facility projects are capital-intensive; a single mid-sized maintenance facility can consume a meaningful fraction of $21 million. If your project is a facility, understand that you are competing in an extremely tight category and make the case for why this specific facility unlocks service that nothing else does.

The application mechanics that quietly disqualify people

None of the strategy above matters if you cannot submit. The recurring failure modes on FTA competitive programs are consistent:

Registration. Submission runs through Grants.gov. Confirm an active SAM.gov registration with a current UEI today, not in September. SAM renewals routinely take two to three weeks and expire without the kind of warning anyone notices. An expired registration on September 21 is a total loss regardless of how good the project is.

Local match. Federal share on FTA capital programs generally runs to 80 percent, leaving a 20 percent local match, with some categories differing. Have your match documented and committed — a board resolution, an executed local funding agreement, a state grant award letter. "Anticipated" match is a scoring liability, and in a competition this tight it is a decisive one.

Project readiness. In constrained cycles, FTA weights readiness heavily, because an agency that cannot obligate is an agency that returns money. Completed NEPA, secured site control, finished design, and a realistic procurement timeline are worth more in FY2026 than an ambitious vision. If you have a shovel-ready project and an aspirational one, submit the shovel-ready one.

Coordination with your state DOT and MPO. Letters of support are table stakes. Evidence that the project is programmed in the relevant TIP or STIP is substantive.

The pattern behind the number

FTA's bus programs are not the only place this is happening. Across DOT and other infrastructure agencies, the FY2026 pattern has been consistent: smaller competitive pots, and evaluation priorities rewritten toward conventional and near-term technology. We saw a version of this in FTA's transit accessibility grant programs earlier in the cycle.

For transit agencies, the durable lesson is about planning horizon. A fleet transition plan built on the assumption of consistent annual federal zero-emission capital support has just encountered a year where that support fell sharply and its priority inverted. That does not mean abandoning the transition — it means building transition plans with enough flexibility that a single lean federal year does not strand a depot full of charging infrastructure with no buses to charge.

FTA Acting Deputy Administrator Matthew Cahill framed the program in the plainest possible terms: "Every day, millions of American families rely on buses to get around their communities." That is the argument that wins this cycle. Not the propulsion technology — the riders.

Applications close September 21, 2026. If your SAM registration is not current, fix that before you write another paragraph.
