To help increase American energy independence, the Rural Energy for America Program (REAP), administered by the USDA, provides guaranteed loan financing and grant funding for renewable energy systems and energy efficiency improvements. There are three types of funding available: Loan guarantees on loans up to 75 percent of total eligible project costs Grants for up to 50 percent of total eligible project costs Combined grant and loan guarantee funding up to 75% of total eligible project costs Renewable energy system grants can be anywhere from $2,500 to $1 million, and energy efficiency grants can range from $1,500 to $500,000. It is important to note that only non-residential costs are eligible to be reimbursed. For example, the electrical service for a farm property serves the agricultural side of things and the residence. Even though the costs are in one utility bill, you can only report the costs from your agricultural and business operations.
