Small Product and Appliance Energy Efficiency Standards

Connecticut product energy efficiency standards are an effective means to save energy and reduce residents' utility bills. In 1987, the Connecticut General Assembly first recognized the benefits of new product energy efficiency (EE) standards.  The state established product standards for -luminaires, light ballast and showerheads.  Since then, Connecticut has adopted 21 product energy efficiency standards.  Although Federal law has preempted, or replaced, some of CT’s EE standards, DEEP continues to support and adopt new product standards.  DEEP understands that more efficient products are a way to lessen pollution, while saving energy and money.

2017 - Connecticut's Current EE Small Product and Appliance Standards

Connecticut law requires the following products that are sold, offered for sale, or installed to meet energy efficiency standards.  

  • Bottle-Type Water Dispensers
  • Commercial Hot Food Holding Cabinets
  • Compact Audio Players
  • Digital Versatile Disc Players
  • Digital Versatile Disc Recorders
  • Pool Heaters
  • Portable Electric Spas
  • Residential Pool Pumps
  • Televisions
  1. Products sold wholesale in CT for final retail sale or installation outside the state.
  2. Products installed in mobile manufactured homes at the time of construction.
  3. Products designed expressly for installation and use in recreational vehicles.
Product Testing:

Connecticut generally adopts either California, or the U.S. Department of Energy’s product testing standards.  These standards describe the product testing procedures and energy efficiency levels required for compliance with the law.

Product Certification:

In Connecticut, certification is required prior to selling products in Connecticut. Connecticut regulated products listed as “certified” in the California Energy Commission’ s active Appliance Efficiency database are automatically considered compliant.


Any person who violates the energy efficiency appliance standards shall be subject to a civil penalty of $250 per day/per offense.
