Energy-efficient upgrades and sustainable practices often have upfront costs that often discourage homeowners from making energy-efficient upgrades. However, there are a variety of incentives that can make these upgrades more accessible and affordable. We have outlined the current incentives for energy, water, and transportation upgrades. As new incentives become available, we will update this page.

The Alternative Energy Revolving Loan Program (AERLP) provides zero-down, low-interest loans of up to $40,000 to individuals, small businesses, nonprofit organizations, and government entities in order to increase investments in alternative energy systems and energy conservation measures in Montana.
The program, which is managed by the Montana Department of Environmental Quality’s Energy Office, has financed more than 500 renewable energy installations across the state since its first loan in 2003 for an off-grid solar array in Belt. Eligible technologies include solar PV, solar thermal, geothermal, EPA-certified low-emission pellet or wood stoves, wind, and micro-hydro. Energy conservation measures may be included in a loan when installed in conjunction with an alternative energy system. For program terms and an application form, click here.
