Administered by Montana-Dakota Utilities Co.
Montana-Dakota Utilities offers Montana residential customers rebates on high-efficiency natural gas furnaces (95% AFUE or higher) for $300, programmable thermostats ($15–$60 depending on features), and LED light bulbs (up to $5–$7 per bulb, max 40 bulbs per account). Apply by completing the relevant application form, submitting it with sales receipts or dealer invoices to Montana-Dakota, and expect a check payment within 4–6 weeks; note that funding is limited and processed first-come, first-served on a plan-year basis (March 1–February 28).
You can help Montana residential customers access furnace rebates ($300 for 95% AFUE or greater units on replacements) and thermostat incentives by ensuring equipment meets program specifications and helping customers submit complete applications with invoices. Tier 1 programmable thermostats require contractor installation with a qualifying new furnace, while Tier 2 Wi-Fi thermostats do not; all applications must include dealer sales invoices and are processed in order received until plan-year funding depletes.
This plan-year-funded (March 1–February 28) program targets Montana residential natural gas and electric customers with rebates for furnace replacements (95% AFUE, $300), programmable thermostats ($15 or $60 depending on connectivity and features), and LED bulbs (50% of package price, capped at $5–$7 per bulb, max 40 per account). Payments issue as checks processed within 4–6 weeks; applications are processed sequentially until annual funding depletes, with new construction and fuel conversions ineligible for the natural gas heating program.
