Maryland

Applicable Territory:Maryland, USA
Standard: Mandatory

Pre-empted by the U.S. Energy Independence & Security Act of 2007 (H.R.6)

Senate Bill 674
Maryland State Energy Administration
Maryland Energy Efficiency Standards Act

In 2004 the Energy Efficiency Standards Act (EESA) became law in the State of Maryland. The General Assembly passed the EESA to establish minimum energy efficiency standards on nine separate products. While five of the nine appliances covered by the EESA were preempted by the Federal Energy Policy Act of 2005 immediately or by the end of the year, the EESA currently remains in effect for the following products sold or installed in the state: (Dates listed in parenthesis signify the year the standard takes effect.)

1. Unit heaters* (2005)
2. Commercial refrigeration cabinets (2005)
3. Large packaged air-conditioning equipment* (2005)

*Will be implemented for some time until federal standards take place.

On January 20, 2006, the new proposed regulations implementing the EESA were published in the Maryland Register. The new EESA proposed regulations incorporate the EESA amendments enacted June 2005 and address the preemptions issues caused by the federal Energy Policy Act of 2005. In 2007, the state of Maryland further passed the Maryland Energy Efficiency Standards Act of 2007 (SB674), with provisions covering single voltage external AC-DC adapters, among other products.
