Technical Amendments Made to Power Supply Energy Standards, Deadline for Input on Residential Furnace/Water Heater Petition Extended

The U.S. Department of Energy has amended certain aspects of the mandatory energy efficiency standards and scope of coverage for external power supplies. The contents of these technical amendments correspond with provisions enacted by Congress through the Power and Security Systems Act and EPS Improvement Act. The DOE is also correcting a misprint related to a table detailing certain statutorily-prescribed requirements.

As a result of these provisions, power supply circuits, drivers and devices designed exclusively to be connected to and power three key categories of products – (i) light-emitting diodes providing illumination; (ii) organic light-emitting diodes providing illumination; and (iii) ceiling fans using direct current motors – are excluded from the external power supply definition. Additionally, the no-load mode standards will not apply to certain external power supplies certified to the DOE as being designed to be connected to a security or life safety alarm and surveillance system component until the effective date of any amended external power supply standards that the DOE publishes through a final rule in July 2021. Finally, the DOE’s current table listing the active mode standards for Class A external power supplies has been amended to match the statutory text.

Separately, the DOE has extended from 30 January to 1 March the deadline for public input on a petition on whether the agency should (i) issue an interpretive rule stating that its proposed energy conservation standards for residential furnaces and commercial water heaters would result in the unavailability of “performance characteristics” within the meaning of the Energy Policy and Conservation Act of 1975 and (ii) withdraw its proposals for amended standards for those products/equipment based upon such findings.
