Low-Income Multifamily Building Retrofits

FON-026-2026

Through this Funding Opportunity Notice (FON) Efficiency Maine is seeking applications for energy efficiency projects in low-income multifamily buildings in Maine.

This initiative offers incentives that are approximately 30% higher than typically provided under the Commercial and Industrial Prescriptive Initiatives (CIPI), with the intent of accelerating the conversion to efficient systems. Interested participants can find more information about this program and instructions on how to apply in the FON document posted below under “Program Documents.”

Retrofit incentives are for the replacement of existing (operating) equipment that’s less than 16 years old.
