USDA's Rural Energy for America Program (REAP) once issued a grant before construction and reimbursed the cost. A final rule effective October 16 moves the award to after a year of operation and drops the cap from 50% to 25%.
For a farmer who wanted to put solar on their land, the federal money used to arrive before the array did. The U.S. Department of Agriculture's Rural Energy for America Program awarded grants to cover up to half the project cost, with the farmer paying the installer and the government reimbursing the bill. A final rule the agency published in the Federal Register on October 1, 2026 replaces that timing. Under the new rules, a farm must build the project, run it for 12 months, and submit a year of post-installation meter data alongside a year of pre-installation data before any federal dollar moves. The construction-period risk has moved from the Treasury to the balance sheet of the operation that wants the array.
The Inflation Reduction Act lifted REAP grants to cover 50% of project cost; the final rule drops that ceiling to 25%. The agency's stated rationale is that a post-completion, performance-validated award reduces program risk and targets funding at projects that have already proven they produce. The rule is not yet effective as of October 1, 2026. Its stated effective date is October 16, 2026, and USDA is accepting public comments through November 2, 2026.
Already-awarded grants are now in limbo. The Environmental Law & Policy Center has filed suit seeking continued processing of pending applications under the old rules, and the center says the new rule's foreign-adversary supply-chain provision captures most of the global solar supply chain. That characterization is the center's framing, not a court finding. The new rule's own summary lists retroactive application, grant caps, cropland exclusions, and supply-chain restrictions among the provisions subject to public comment; the operative text will govern any final disposition. Earlier in the year, a day-one executive order froze $911 million in REAP dollars before that funding was released. The rule rewrite is the next move in the same arc, not the first.
Other clean-energy dollars remain on the books. The Inflation Reduction Act's clean-energy investment tax credit and production tax credit remain available, and several states run their own agricultural energy programs that can be stacked. Third-party-owned arrays let a farm host solar without buying the equipment: a developer builds, owns, and operates the array, and the farm either buys the power under a long-term contract or hosts it for a lease payment. Rural electric cooperatives have member-solar programs of their own, and at least one co-op trade group has published model terms for member-financed arrays. None of these is a one-for-one replacement for a 50% REAP grant. The construction-period risk is real. The next dollar is still available.
Public comments on the Federal Register filing close November 2, 2026, and the rule's stated effective date is October 16, 2026, unless USDA moves either. The ELPC complaint seeks continued processing of pending applications under the rules in effect when those applications were filed; the complaint's requested relief has not been adjudicated. Farmers with already-awarded grants, projects mid-financing, or 2026–27 build plans have 32 days from October 1 to weigh in on the rule that will govern their next project.
