Sign up for e-mail updates on regulations for this and other products

The Department of Energy (DOE) has completed a rulemaking to amend the current energy conservation standards for liquid-immersed, medium voltage dry-type, and low-voltage dry-type distribution transformers. This activity is mandated by the Energy Policy and Conservation Act (EPCA).

Recent Updates

DOE published a final rule regarding amended energy efficiency standards for liquid-immersed, medium-voltage dry-type, and low-voltage dry-type distribution transformers. 78 FR 23335 (April 18, 2013). The distribution transformers final rule was the DOE's first "negotiated rulemaking," conducted under the Federal Advisory Committee Act and the Negotiated Rulemaking Act.

Related Rulemakings

DOE is also conducting a negotiated rulemaking for low-voltage dry-type distribution transformers energy conservation standards. The docket number is EERE-2011-BT-STD-0051.

Statutory Authority

The current energy conservation standards for distribution transformers are mandated by Part A–1, the "Certain Industrial Equipment" of Title III of the Energy Policy and Conservation Act (EPCA), as amended. (42 U.S.C. 6311–6317). This equipment is treated as covered equipment under Part A-1. (42 U.S.C. 6317(a)) In addition, the Energy Policy Act of 2005 (EPACT 2005) amended EPCA to set energy conservation standards for low-voltage dry-type distribution transformers. (42 U.S.C. 6295(y))
