Manufacturers Association (NEMA) today expressed
its overall satisfaction with the Department of Energy’s final rule
establishing increased energy conservation standards for distribution
is appreciative of the open process and fair hearing of all perspectives that
DOE allowed for in the negotiations,” said NEMA Assistant Vice President for Industry
Operations John Caskey. “This transparent process gave all interested parties,
including transformer manufacturers the opportunity to discuss existing
technologies, market forces, benefits and burdens, and we believe this input
was largely reflected in the final rule.”
the fall of 2011, DOE hosted a negotiated rulemaking, where stakeholders
gathered to discuss the justification for higher energy efficiency standards
for all three classes of regulated distribution transformers: low voltage
dry-type, medium voltage dry-type, and medium voltage liquid-immersed.
current energy conservation standards, distribution transformers are already
the most energy-efficient product that DOE regulates, at 97–99 percent efficiency.
NEMA members, however, believed there was an opportunity to increase energy
conservation without unduly burdening the sectors that supply materials for
transformers, the manufacturers, and the consumers of transformers.
the rulemaking process, several performance tiers above those selected in the
final rule were proposed and reviewed. NEMA manufacturers provided data and
analysis to DOE and participants in the negotiations and expressed its strong
reservations with higher performance tiers which relied on materials with
limited availability and few suppliers and which would have required
significant capital investment for any company that lacked amorphous material construction
capabilities at the outset.
efficiency levels for medium voltage liquid immersed transformers announced
today remain unchanged from DOE’s proposed rule and NEMA’s recommended levels. These
efficiency levels ensure maximum energy savings while remaining within the bounds
of technical feasibility and maintaining a competitive marketplace.
low voltage dry-type transformers, the final rule requires the efficiency
levels in TSL-2, whereas the proposed rule would have required TSL-1. During
the negotiations, NEMA expressed reservations about the higher efficiency levels
out of concern for their impact on small manufacturers.
efficiency levels for the third category of transformers—medium voltage dry-type—had
been previously agreed to by all parties during the negotiations.
should be commended for an open and transparent rulemaking process,” said Caskey.
“We believe the final rule goes a long way in promoting efficiency while
maintaining a vibrant transformer manufacturing industry.”
NEMA is the association of electrical equipment and medical imaging manufacturers, founded in 1926 and headquartered in Arlington, Virginia. Its member companies manufacture a diverse set of products including power transmission and distribution equipment, lighting systems, factory automation and control systems, and medical diagnostic imaging systems. Worldwide annual sales of NEMA-scope products exceed $120 billion.
