What is not covered in Maine
No open program with a published amount was found for induction range or cooktop, electrical panel upgrade. That does not prove nothing exists: a municipal utility or a pilot can run its own offer, and the methodology page lists the program pages that could not be read. Where the federal credit used to cover one of these, it has ended.
