See equipment requirements listed above for eligibility or visit program web site. 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. Equipment must be installed during the same program year in which incentives are sought. See program web site listed above to view application form or to see more general program information.
