Montana-Dakota Utilities Co.

Montana-Dakota Utilities (MDU) offers several residential rebates on energy efficient measures and natural gas equipment. New furnaces, water heaters and programmable thermostats are eligible for a rebate incentive if the equipment meets program efficiency standards. New furnaces must be replacing a working model with an AFUE of 80% or less and be rated at least 92% AFUE. Customers converting electric service to natural gas are also eligible for the furnace and water heater rebates if efficiency requirements are met. MDU issues rebate payments in the form of a check, not a utility bill credit. Application forms must be fully completed with equipment information such as invoice or receipt, brand, model number, serial number, installation date and dealer information. See program web site listed above to view application form or to see more program information. Only South Dakota residential MDU customers under service rates 60 or 66 are eligible for rebates.
