Maryland Appliance and Equipment Energy Efficiency Standards

Summary

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 for comprehensive information about appliance standards.

On May 29, 2022, House Bill 772 was enacted as Chapter 564 of the Acts of the Maryland General Assembly of 2022. The legislation establishes minimum energy efficiency standards for eleven new products sold or installed in Maryland and establishes testing, certification, inspection, and enforcement procedures for ensuring compliance with established standards.​
