Clean Energy Business Grants Open Now — August 2026

The 67 open clean-energy grants, by what the money is for

All 67 grants, grouped into five lanes and sorted by deadline inside each. 30 states appear. Loans, tax credits, utility rebates and prize competitions are counted in the numbers and handled in their own sections — none of them is printed here as a grant. Where a program’s own notice contradicts its deadline, the row says so.

Closing in the next 60 days

8 of the 67 open grants carry a published deadline between today and October 26, 2026, soonest first. Six of the eight are federal — five research awards plus a nuclear licensing cost-share — which tells you plainly where the dated clean-energy money is.

Why this page is organised by purpose, not by size

160 rows in one flat table would be useless. The organising principle here is what the money pays for, because in clean energy that is the thing that decides whether you are eligible — far more than your revenue, your state or your headcount. A solar installer and a battery-materials startup are both “clean energy” and share almost no programs.

There is a sixth lane with nothing in it, and that is the most useful fact on this page. Agricultural and rural on-farm energy — the lane that USDA REAP occupies, and the one that reaches more ordinary rural businesses than every other clean-energy grant combined — has zero open grants in this catalog snapshot. REAP is recorded as paused. We have given it its own section rather than quietly dropping it, because a page that lists 67 grants and does not mention the missing one is telling you less than it appears to.

The lane labels are ours, assigned from each program’s own stated purpose, and they are a judgement call in a handful of cases — a state SBIR match funds research, but the research might be a heat pump. Where a program straddles two lanes we placed it where its eligibility rules bite hardest. The chip in each row tells you which lane we chose; the program’s own page tells you what it actually says.

If you want solar or an efficiency retrofit on your own building

Start with your utility, not with grants.gov. Eleven utility and state efficiency programmes in this slice are open right now and they behave nothing like a grant competition: you book a free assessment, a contractor installs, and the incentive is netted off the invoice. Mass Save covers 70–100% of a small-business lighting or refrigeration project in Massachusetts and finances the rest at 0%. Small Business Energy Advantage in Connecticut pays up to 50% and finances the balance at 0%. Focus on Energy in Wisconsin adds solar at $50/kW up to $25,000. None of these requires a proposal, and none of them appears on a “clean energy grants” list, which is precisely why they go unclaimed.

Then finance the gap, if there is one. Commercial Property Assessed Clean Energy financing covers up to 100% of project cost with no money down and is repaid through a property tax assessment over as long as 25 years — Connecticut and Rhode Island both run one, and your municipality has to have opted in. Michigan Saves lends from $5,000, sometimes at 0% through a utility partner.

24 rows — the clean-energy-specific programmes among the 93 open non-grants. The remaining 69 are general-purpose loans, state R&D and jobs tax credits, accelerators and pitch competitions that happen to list clean technology as an eligible industry; they are counted in the totals and summarised below rather than listed row by row. Work the full set in the database.

The biggest clean-energy money is a tax credit, and you do not apply for it

The distinction is not pedantry, it changes what you do next. A grant is money you compete for before you spend; a credit reduces tax you owe after you spend, which means it is worth nothing in a year you owe no tax unless the credit is refundable, transferable or direct-pay eligible. Several of the clean-energy credits are — §45X, §45Y and §45Q are transferable, which is why credit-transfer markets exist — but you need a project and a filed return first either way. Our Section 48 and 48E ITC guide works through the rate stack, and the Section 45X guide covers the per-unit manufacturing credit.

One of them is not like the others. §48C is a competitive allocation you do apply for through DOE, and it had no announced new round as of May 2026. If a page tells you to “apply for the 30% clean energy tax credit”, it has confused §48C with §48E. And §179D is a deduction, not a credit — it lowers taxable income rather than tax owed, so its cash value is your marginal rate times the deduction, not the headline per-square-foot figure.

The 42 credits counted in the open 160 are mostly not clean-energy credits at all: they are the state R&D credits and state jobs credits that list clean technology among their eligible industries. They are real money for a clean-tech company — the federal R&D credit alone offsets up to $500,000 a year of payroll tax for a qualifying small business — but they fund research and headcount, not kilowatts.

Farms and rural businesses: the REAP hole

What that means in practice. If you run a farm, a grain dryer, a rural workshop or a small food processor and you have been told there is federal grant money for your solar array, the program you were told about is REAP, and it is not currently taking applications in our data. Its historic pattern — quarterly windows, with FY2024 deadlines on March 31 and September 30 — is the thing to watch for; the NOFO on rd.usda.gov is where a restart would show up first. We have kept its page live rather than deleting it precisely so that the status is visible: see the REAP page.

What is actually open for a rural business in the meantime is smaller and different in kind. Nebraska Dollar and Energy Saving Loans lend up to $500,000 for efficiency and renewable projects at 5% or less. USDA’s Business & Industry guarantee backs up to 80% of a commercial loan for a rural business, energy project or otherwise. Nebraska’s Rural Development Act credits pay $3,000 per new employee plus $2,750 per $50,000 invested outside urban centres. Focus on Energy runs an agribusiness track in Wisconsin. None of these is REAP, and pretending otherwise would waste your time.

Two USDA biofuel and biomass vehicles in this slice are also shut: Section 9003 biorefinery assistance publishes competitive notices rather than staying open, with the FY2025 notice status recorded as uncertain, and the Higher Blends Infrastructure Incentive Program has had no active competition since its FY2022 round.

What moved, and when — the volatility this slice carries

Federal clean-energy funding has changed more in the last eighteen months than any other slice we track, which makes a stale “open” here unusually expensive. These are the changes recorded in the catalog, each with the date attached, so you can tell a program that is between rounds from one that no longer exists.

• DOE’s Office of Clean Energy Demonstrations was dissolved in November 2025. No new funding notices are anticipated for the demonstrations program; existing awards continue and successor programs are undecided.
• The Industrial Demonstrations Program was effectively cancelled with it. Its $3.7B of Phase 1 awards were terminated following the OCED dissolution, and no Phase 2 notice is expected.
• §30C, the alternative-fuel refuelling credit, was terminated by the OBBBA for property placed in service after December 31, 2025. EV-charger installations completed on or before that date in a qualifying census tract can still be claimed.
• §48E’s wind and solar window was shortened. Wind and solar must be placed in service by December 31, 2027 unless construction began by July 4, 2026. Other clean-electricity technologies keep the later phase-down.
• §45X wind components must be sold before December 31, 2027; most other eligible components phase down from 2030 through 2032.
• §45Z was extended, not cut. The July 2025 OBBBA pushed the clean fuel production credit from a 2027 sunset out to fuel produced and sold through December 31, 2029, and equalised the sustainable-aviation-fuel rate.
• §48C has announced no new allocation round as of May 2026. Round 2 certificate holders from the 2023–2024 allocations can still claim.
• The DOE ITAC implementation grant is on hold pending a program restart, recorded late 2025 — the one federal grant that paid small manufacturers up to $300,000 to act on an energy audit.
• USDA REAP is paused, with no published next window in our data.
• EPA’s Environmental Justice Collaborative Problem-Solving program is closed, with EPA terminating environmental justice grants since May 2025 and no FY2026 notice issued.
• DOE grid programs are between cycles. GRIP Round 1 was awarded in 2023; the FY2026 SPARK reconductoring round closed with full applications due May 20, 2026.
• CalSEED’s Cohort 8 deadline passed on March 31, 2026 and the next California clean-energy concept call had not opened as of the snapshot.
• DOE’s Title 17 §1703 clean energy loan guarantee is winding down, though pre-application consultation was still recorded as available.

The counterweight: 160 programs in this slice really are open, and the durable ones are the least glamorous — utility efficiency programmes run by regulated utilities on state-approved budgets, state SBIR matching grants funded by state legislatures, and the statutory tax credits. Those three families have moved the least, and they are where a small business should look first.

The numbers behind “clean energy grants open now”

268 of the 736 programs in the catalog touch clean energy; 160 are open today and 67 of those are grants. The other 108 of the 268 are between rounds, paused, closed or discontinued. Median maximum award among the open grants: $200,000.

Two numbers are worth sitting with. First, 53 of the 67 grants are rolling — no deadline at all — which means the urgency in most clean-energy grant content is manufactured; what limits you is appropriation, not the calendar, and several of these close early when a state’s funds run out. Second, 50 of the 67 are state programs against 16 federal. The federal clean-energy grant machine is the part that has been dismantled; the state layer has not moved nearly as much, and it is the layer most businesses have never looked at.
