DOE Issues New Efficiency Testing Standards for Distribution Transformers

April 27, 2006

The U.S. Department of Energy (DOE) today announced that it has published a new test procedure ruling to gauge energy efficiency in distribution transformers, which are normally placed on utility poles or are housed underground, taking electricity from the electricity grid and supplying it to homes and commercial buildings at the required voltage. This final rule means testing standards will be more rigorous in determining the degree of energy efficiency of distribution transformers; and meets DOEs commitment to complete its rulemaking activities as scheduled in its January 31, 2006 Report to Congress.

"Improving Americas energy efficiency is a cornerstone of this Administrations energy policy," Andy Karsner, Assistant Secretary for Energy Efficiency and Renewable Energy said. "This new rule reinforces DOEs commitment to moving diligently on an expedited schedule for appliance standards, and providing Americans with the most energy-efficient appliances and equipment available."

The final distribution transformers rule also defines products covered by the test procedure, establishes testing and sampling provisions for manufacturers, and delineates enforcement testing for distribution transformers.

DOE continues to focus on increasing the transparency and speed of the standards rulemaking process. The Appliances and Commercial Equipment Standards Program, administered by DOEs Office of Energy Efficiency and Renewable Energy, is responsible for managing test procedures and energy conservation standards for consumer products and commercial equipment.
