Alternative Energy Revolving Loan Program

July 29, 2025

Summary

The Alternative Energy Revolving Loan Program (AERLP) provides loans to individuals, small businesses, local government agencies, units of the university system, and nonprofit organizations to install alternative energy systems that generate energy for their own use. Funding may be used to provide loans for construction of alternative energy systems and capital investments for energy conservation purposes when done in conjunction with an alternative energy system. The program is funded by air quality penalties collected by the Department of Environmental Quality (DEQ). The program is administered by DEQ, which is responsible for developing the rules.

Alternative energy systems are defined by the Montana Code as "the generation system or equipment used to convert energy sources into usable sources." Technologies included in this definition are fuel cells that do no require hydrocarbon fuel, geothermal, low emissions wood or biomass, wind, photovoltaics, small hydropower (under 1 megawatt), and other recognized non-fossil forms of generation. DEQ provides a technical review and approval of systems proposed for the loan program.

In 2005, SB 50 added local government agencies, units of the university system, and nonprofit organizations to the list of eligible sectors, and allowed energy conservation measures to be financed when installed with an eligible alternative energy system. Interest rates are set annually and are fixed for the term of the loan. The rate for 2025 is 3.5% with a maximum loan amount of $40,000 and a loan term of up to 10 years with no early payment penalty.

DEQ will accept and process loan applications on a quarterly cycle (July, October, January, and April). Approved projects will be ranked according to criteria published in the Administrative Rules of Montana (ARM) Title 17, Chapter 85. This criteria includes items including, but not limited to, amount of energy produced, diversity of technology in the portfolio, return on investment, and geographical diversity of the project portfolio. Once a loan is approved, the applicant will be informed as to whether funds are currently available and when new funds are anticipated if funds are not currently available.
