USDA REAP grant changes take effect, with post-completion applications and solar limits

USDA's revised Rural Energy for America Program grant rule takes effect on October 16, 2026. The rule was published October 1, with comments due November 2. Today's development is the effective date, not a newly announced funding award or confirmation that an application window is open.

USDA's revised Rural Energy for America Program grant rule takes effect on October 16, 2026. The rule was published October 1, with comments due November 2. Today's development is the effective date, not a newly announced funding award or confirmation that an application window is open.

The rule changes grants to a post-completion model. Projects must be built and operational before an application, with 12 months of actual energy-production or savings data and pre-installation data. The preamble says completion generally must fall 12 to 24 months before application, with a 12-to-36-month exception for the first window under the new regulation.

Ground-mounted solar photovoltaic systems and wind turbines installed on certified cropland are ineligible. The rule also excludes solar and wind systems, including roof-mounted systems, containing a component made in a country designated as a foreign adversary. It identifies a transition exception for projects completed before publication; eligibility should be checked against the actual rule rather than a blanket claim that every farm solar project is banned.

USDA also excludes multilocation projects, stand-alone energy storage and retrofits that add storage to an existing renewable-energy system from these grant provisions. The rule lists electric vehicles, chargers and charging stations as ineligible. These are program-specific grant limits, not a general prohibition on buying or installing the equipment.

USDA says applications with Form 1940-1 signed by both the applicant and agency before the effective date may continue under applicable terms. Its October 2 release says annual notices will announce application opening and closing dates. An effective regulation is not itself an invitation to submit an application today.

For rural businesses, the change affects when funding can be sought and which projects may qualify. Building first creates financing and award risk; completing a project does not guarantee a grant. Applicants should confirm current notices, project eligibility and transition rules with USDA before committing funds, rather than relying on an expected reimbursement.
