Appliance Efficiency Standards
Appliance efficiency standards set essential requirements for residential and commercial products to help maintain the performance and quality of the product while reducing its energy and water consumption. These standards help ensure poor quality, inefficient, and wasteful products do not enter the supply chain, and protect consumers from purchasing appliances that would drive up their utility costs.
Maine’s Appliance Efficiency Standards, 06-096 C.M.R. ch. 180, (Chapter 180) became effective November 3, 2022, to help Maine meet the greenhouse gas reduction goals established in 38 M.R.S. § 576-A, and is intended to operate in conjunction with the efforts of other states.
