Energy losses associated with electrical distribution systems amount to nearly nine percent of total global electricity consumption. Distribution transformers are responsible for approximately 30 to 35 percent of these losses.

Preliminary analysis  indicates that approximately 75 TWh of final energy and 30 million metric tons of CO2 emissions can be saved in 2030 by adopting the world’s best efficiency standards in participating Clean Energy Ministerial (CEM) economies. To date, nearly 30 economies around the world have developed minimum efficiency standards or labeling programs for transformers.

SEAD has published a series of reports analyzing the potential for alignment of distribution transformers efficiency levels. For more information and to download the reports click here.


Standards & Labeling: The S&L working group has initiated an international collaboration of technical and policy experts in transformer energy efficiency. This collaboration is intended to promote alignment and improvements in the scope and stringency of international standards and labeling programs. The collaboration is led by Canada with participation from Australia, Korea, the United Kingdom, and the United States.
