Maine Appliance and Equipment Energy Efficiency Standards

August 24, 2023


Note: The federal government has imposed and updated appliance efficiency standards through several legislative acts,* and now has standards in place or under development for 30 classes of products. In general, states which had set standards prior to federal action may enforce their own standards until the federal standards take effect. States that had not set standards prior to federal action must use the federal standards. This summary addresses (1) state appliance standards that will be in place until the federal standards take effect and (2) products for which the federal government is not currently developing an efficiency standard. Much of the information in this summary comes from the Appliance Standards Awareness Project (ASAP).Visit the ASAP web site and the U.S. Department of Energy's Appliance and Equipment Standards site for comprehensive information about appliance standards.

Maine adopted appliance efficiency standards for a range of products in 2019.  Additionally, the state is phasing out the sale of fluorescent lighting. Screw-base CFL bulbs will be phased out on January 1, 2025, and pin-base CFL and fluorescent tubes will be phased out on January 1, 2026. The following products have efficiency standards:

  • Computers and Computer Systems 
  • Faucets

  • Hot Food Holding Cabinets 
  • Portable Electric Spas
