Significant efficiency gains for one major class of products but outdated technology for the other major class
Washington, D.C. (April 10, 2013): Late yesterday, the U.S. Department of Energy (DOE) issued new energy efficiency standards for electric distribution transformers. In the final rule, relative to a draft standard issued a year ago, DOE improved the standard for "dry-type" transformers (those primarily used in buildings) but left the proposed standard for "liquid-immersed" transformers (those most commonly owned by utilities) unchanged.
"The new standard for dry-type transformers is a good step forward and represents a compromise between the positions of the transformer industry and energy efficiency advocates," stated Steven Nadel, executive director of the American Council for an Energy-Efficient Economy (ACEEE). "However, the final standard for liquid-immersed transformers....read more
