AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy.
ACTION: Notice of Proposed Rulemaking and public hearing.
SUMMARY: Pursuant to Section 346(a) of the Energy Policy and Conservation Act as amended (EPCA), 42 U.S.C. 6317(a), the Department of Energy (DOE or the Department) proposes to adopt test procedures for measuring the energy efficiency of distribution transformers. The Department proposes to use these test procedures in the process of evaluating whether and what efficiency standards are appropriate for distribution transformers. If standards are promulgated, then use of these test procedures would be required to determine compliance and as a basis for representations. The proposed rule would incorporate by reference clauses from test procedures contained in commercial standards. The Department is proposing to use one of two alternative sets of standards as the primary references: alternative (A) is primarily based on American National Standards Institute (ANSI)/Institute of Electrical and Electronics Engineers (IEEE) standards C57.12.90-1993 and C57.12.91-1995, and alternative (B) is based on National Electrical Manufacturers Association (NEMA) standard TP 2-1998, pending its approval by ANSI.
