Distribution Transformers

The Energy Policy and Conservation Act (EPCA) of 1975 

established an energy conservation program for major household 

appliances. The National Energy Conservation Policy Act of 1978 

amended EPCA to add Part C of Title III, which established an 

energy conservation program for certain industrial equipment. The 

Energy Policy Act of 1992 amended EPCA to add certain 

commercial equipment, including distribution transformers.

The Department of Energy, Office of Energy Efficiency and 

Renewable Energy, Building Technologies Program conducts the 

program that develops equipment energy conservation standards 

and has overall responsibility for rulemaking activities for 

distribution transformers in fulfillment of the law.

The first step in developing energy conservation standards was 

the Secretarial determination in 1997 that, "Based on its analysis 

of the information now available, the Department has determined 

that energy conservation standards for transformers appear to be 

technologically feasible and economically justified, and are likely 

to result in significant savings" 62 FR 54809 (October 22, 1997). 

The Department is currently conducting two rulemakings for 

Distribution Transformers: an energy conservation standard and a 

test procedure.
