Distribution Transformers
Test Procedure Supplemental Notice of Proposed Rulemaking (SNOPR)

The Department of Energy is now publishing its Test Procedures Supplemental Notice of Proposed Rulemaking (SNOPR) for Distribution Transformers. The SNOPR follows from the Notice of Proposed Rulemaking and the Reopening Notice.

SUMMARY: The Department of Energy previously published a Notice of Proposed Rulemaking (NOPR) to adopt test procedures for measuring the energy efficiency of distribution transformers under the Energy Policy and Conservation Act (EPCA or the Act), definitions to delineate the products covered by the test procedures and provisions (including a sampling plan) for implementing the test procedures. The Department now proposes to adopt revised test procedures for distribution transformers, primarily based upon existing industry standards. The proposed rule also contains revised definitions and provisions to implement the test procedures, calculation methods that manufacturers could use to determine the efficiency of some of their models, and enforcement methods for distribution transformers. The Department would use the test procedures in evaluating whether, and to what extent, energy conservation standards are warranted for distribution transformers. If standards are promulgated, then these test procedures and the other provisions proposed today would be used to determine efficiency and assess compliance of the transformers subject to the standards.
