The National Electrical Manufacturers Association (NEMA) has initiated the NEMA Premium Efficiency Transformer Program, which helps utilities, commercial buildings, and industrial plants incorporate electrical transformers into their operations.

The U.S. Department of Energy (DOE) adopted NEMA’s original
publication, NEMA TP 1-2002 Guide for Determining Energy Efficiency for
Distribution Transformers. The press release states, “the new NEMA
Premium Efficiency Transformer designation requires 30 percent fewer
losses than existing DOE regulations (10 CFR 431) for low-voltage
dry-type distribution transformers”.

Under the new program, transformers used for commercial and industrial
applications are covered, however, the program is also being considered
by electric utilities for their commercial and industrial efficiency
rebate programs.

Seven NEMA member manufacturers have committed to providing the
program: Eaton Electrical, Federal Pacific, GE Energy Industrial
Solutions, Hammond Power Solutions, ONYX Power, Schneider Electric, and
Siemens Industry.
