Office of Energy Efficiency and Renewable Energy July 24, 2017 – Federal Register Recent Federal Regulation Documents

This notice announces receipt of and publishes petitions for waivers from Apple, Inc. (``Apple''), Microsoft Corporation (``Microsoft''), Poin2 Lab (``Poin2''), and Hefei Bitland Information Technology Co., Ltd. (``Bitland'') (collectively, ``the petitioners'') seeking an exemption from specific portions of the U.S. Department of Energy's (``DOE's'') test procedure for determining external power supply (``EPS'') energy efficiency. The waiver requests pertain to adaptive EPSs that support a particular International Electrotechnical Commission standard. Under the existing DOE test procedure, the average active mode efficiency of an adaptive EPS must be tested at both its lowest and highest achievable output voltages. The petitioners contend that since their products operate above 2 amps current at the lowest achievable output voltages under rare conditions and for only brief periods of time, the suggested alternative testing approach detailed in their waiver petition requests is needed to measure the active mode efficiency of their products in a representative manner. DOE is granting the petitioners with an interim waiver from the DOE EPS test procedure for the specified basic models of EPSs, subject to use of the alternative test procedure as set forth in this document and is soliciting comments, data, and information concerning the petitions and the suggested alternate test procedure.
