USDA REAP Requirements 2026 | Missouri Solar Grant Guide

Last updated October 29, 2026. REAP rules are changing; check the official links below before you act.

The USDA Rural Energy for America Program (REAP) still exists, but its rules changed on October 16, 2026. If you farm or run a small business in rural Missouri and want help paying for solar, the requirements now matter more than the dollar amounts. Farm shops, grain dryers, irrigation, livestock barns, feed stores, rural shops, and small manufacturers all have high daytime loads that solar can offset. For businesses, REAP is one piece of the funding stack; the federal business tax credit is the other. This guide covers who qualifies, what the project has to look like, how much you pay, when you can apply, and how to pay for the system while you wait.

Quick status: USDA is not accepting REAP grant applications right now. REAP guaranteed loan applications are still accepted. (USDA RD REAP page)

1. Who is eligible for USDA REAP?

Eligible applicants (USDA RD):

Agricultural producers: at least 50% of gross income comes from agricultural operations. Producers do not have to be in a rural area.
Rural small businesses: located in an eligible rural area (50,000 people or fewer) and within SBA size standards. For-profits, cooperatives, and certain rural electric utilities qualify.

Ownership rules under the 2026 rule (final rule; USDA press release):

Affiliates count as one. Entities with common ownership or management, at any percentage and whether direct or indirect, are treated as one entity. Their combined grants cannot exceed the yearly limit.
One award per owner per federal fiscal year. You can't split one operation into several LLCs to get more grants.
The top-level owner applies. A subsidiary owned by another entity cannot apply on its own.*
12 months in business. The business must have existed for at least 12 months before applying.*

*Reported from USDA's October 13, 2026 webinar in a third-party recap (GDS Associates on LinkedIn). Confirm with your State Energy Coordinator.

Not eligible: residential (home) solar.

2. Project requirements: build first, then apply

The biggest change is that REAP grants are now a post-completion, performance-validated program (Federal Register, 91 FR 62600):

The system must be fully built and operating before you apply.
12 months of real data: energy production or savings for the prior 12 months, plus 12 months of usage data from before the install. Save your utility bills now.
Solar on cropland is disfavored or ineligible. Ground-mount solar or wind on cropland is restricted. Plan for rooftops, barns, shops, or non-crop ground.
No multi-location projects. Each project must be at one site.
Batteries must be paired with a renewable system. Stand-alone storage, and batteries added to an existing solar system, are not eligible.
Sized to your usage. The system can't be oversized for the load it serves.
Foreign-adversary components. Solar and wind projects must not use components made in foreign-adversary countries. A third-party webinar recap reports an exemption for equipment installed before October 1, 2026 (third-party: GDS).
Energy audit / assessment. Energy-efficiency projects need an audit by a qualified energy auditor. Renewable projects need documented costs, site control, and equipment sourcing.

3. Cost share: plan on paying at least 75%

REAP grants cover up to 25% of eligible project costs. You cover at least 75% from your own money or a loan (final rule).
Grant range: $1,500 to $500,000 for renewable energy systems and up to $250,000 for energy-efficiency improvements.
About the old 50% grant share: Inflation Reduction Act funds once allowed up to 50%. A third-party recap of USDA's webinar says the 50% share "may be available" depending on the next funding notice (GDS). Don't count on it. Budget for 25% until USDA publishes the notice.

4. Timing: when can you apply?

No application window has been announced. USDA says annual program notices will set the open and close dates (USDA press release).
Expected around early 2027. In the October 13 webinar, USDA reportedly said the funding notice was in clearance and the window should open around the start of calendar year 2027 (third-party: GDS).
The application moves online. USDA plans an online portal, reported as ProsperUS, to replace paper forms.
Grandfathered applications. Applications with a Form 1940-1 "Request for Obligation of Funds" signed by both the applicant and USDA before October 16, 2026 will still be processed under their terms (USDA press release). Unsigned older applications must reapply under the new rules (USDA FAQ).
First-round timing. Because projects need a year of operating data, a system finished in late 2025 or 2026 may be ready for a 2027 application.

5. Paying for the system in year one: the REAP loan guarantee

Because the grant comes after the project is built, you need financing up front. USDA points to the REAP guaranteed loan as the bridge (USDA RD; Under Secretary Glen Smith in a third-party interview):

Covers up to 75% of project cost through your own lender, with a federal guarantee (80% in recent years).
Applications are open now, unlike grants.
Fees: about a 1% upfront guarantee fee and a 0.25% annual renewal fee. Terms can run up to 40 years for real estate.

Talk with an ag or community lender that does USDA guaranteed lending. Ask early, because approval can take weeks to months.

7. Pair REAP with the federal business solar tax credit (Section 48E)

A business- or farm-owned system may also qualify for the federal clean electricity investment credit (IRC §48E). Here's where it stands as of October 2026 under the 2025 tax law (P.L. 119-21):

Deadlines. Solar that began construction by July 4, 2026 keeps the longer timeline. Solar that began construction later must be placed in service by December 31, 2027, or the credit is lost (26 U.S.C. §48E(e)(4); IRS Notice 2025-42). If you're starting a project now, plan to have it running well before the end of 2027.
Credit amount. Under the statute, the base credit is 6%. It rises to 30% for projects under 1 MW, or for projects that meet prevailing-wage and apprenticeship rules (§48E). Bonus adders have their own tests. Your tax advisor confirms what your project qualifies for. We don't promise a credit amount.
Foreign entity (FEOC) rules. Projects that begin construction after December 31, 2025 can't claim the credit if they receive "material assistance" from a prohibited foreign entity. Equipment sourcing must be documented, the same as under REAP's new parts rule.
Selling the credit. If your business can't use the full credit, it can generally be transferred (sold) for cash to an unrelated buyer under IRC §6418 (IRS: elective pay and transferability).
REAP and the credit together. A REAP grant and the tax credit can both apply to one project. A grant can affect your cost basis, so run the numbers with your CPA.

Financing and credit transfer: Solar Sam works with a tax-credit financing partner that can help qualifying customers turn the credit into cash, instead of waiting until tax time. Terms, eligibility, and fees come from the partner and your tax advisor. Ask us for an introduction.

9. The rule may still change

Public comments close November 2, 2026. Submit on the Federal Register page (doc 2026-20178).
Senators' letter, October 27, 2026. 21 U.S. senators asked USDA to reverse the build-first model and requested answers by November 5 (Sen. Welch press release).
USDA's Under Secretary said USDA may adjust the rule after comments (third-party interview).

We'll update this guide when USDA publishes the funding notice.

Frequently asked questions

Is REAP open in 2026? Grants: no. Loan guarantees: yes (USDA RD).

Can I get REAP for solar on my house? No. Residential projects are not eligible.

Can I put a ground-mount array in a crop field? Solar on cropland is restricted under the 2026 rule. Use roofs or non-crop ground.

How much will REAP pay? Up to 25% of eligible costs ($1,500–$500,000 for renewable systems). Don't plan on 50%.

Can a business get both REAP and the solar tax credit? Often yes, if the project qualifies for both. Solar must be placed in service by December 31, 2027 unless construction began by July 4, 2026. Check with your CPA.

When should I start? Now, if you plan to apply in a 2027 window. Collect your bills, line up financing, and get monitoring running from day one.
