NEMA, EEI Announce Premium Efficient Transformers Purchasing Program

July 9, 2008 // Published as a news service by IHS

Under the program - called the EEI Premium Efficient Transformers Purchasing program - NEMA manufacturers will build and EEI utilities will install distribution transformers that meet or exceed the U.S. Department of Energy's (DOE) 2010 efficiency standards well before the regulations become mandatory.

Transformers that meet or exceed these new standards will be designated NEMA Premium Efficiency Transformers to assist buyers in quickly locating compliant products.

Eight manufacturers have committed to providing NEMA Premium Efficiency Transformers to the marketplace, including ABB Inc., Acme Electric Corp., Cooper Power Systems, Federal Pacific, General Electric/GE Prolec, Kentucky Association of Electric Cooperatives, Schneider Electric/Square D and VanTran Industries Inc.

In October 2007, the DOE finalized minimum efficiency requirements for medium-voltage dry-type and liquid-filled transformers. The standards are scheduled to take effect in 2010 and will reduce carbon dioxide emissions by 238 million tons over the next 30 years, said NEMA.

With approximately 1.2 million distribution transformers sold in the U.S. every year, advanced adoption of more stringent standards will save energy and reduce carbon dioxide emissions above and beyond the benefits identified by the DOE. EEI members purchase approximately 65% of liquid-filled transformers sold every year.

"The NEMA Premium mark has long been associated with highly efficient electric motors. [This] announcement extends that recognition to distribution transformers, and demonstrates that utilities and manufacturers are willing to accelerate government mandates where feasible in providing win-win solutions for electricity customers and the environment," said NEMA President Evan Gaddis.

"Energy efficiency is a top priority for EEI's member companies, and the NEMA Premium Efficiency Transformers program will help our members more quickly find and specify high-efficiency transformer units," said EEI President Tom Kuhn. "Ideally, the more manufacturers that participate, the more higher efficiency transformers will be available, and the more kilowatts saved."

Kuhn pointed out that a new federal law makes purchasing the new high-efficiency transformers more economical for utilities.

"The Economic Stimulus Act of 2008 gives a 50% bonus depreciation credit for equipment placed in service this year, which will make transformers purchased and put in service this year that much more economical," he said.
