External Power Supplies
As defined in the Code of Federal Regulations (CFR), “external power supply” means an external power supply circuit that is used to convert household electric current into DC current or lower-voltage AC current to operate a consumer product. 10 CFR 430.2 Manufacturers have been required to comply with the U.S. Department of Energy (DOE) energy conservation standards for external power supplies since 2007.

Recent and Ongoing Activities
DOE has published a Federal Register notice of proposed rulemaking (NOPR) pertaining to energy conservation standards for external power supplies (EPSs). The Energy Policy and Conservation Act (EPCA) requires DOE to periodically determine whether more-stringent, standards would be technologically feasible and economically justified, and would result in significant energy savings. In this NOPR, DOE proposes amended standards for EPSs, and also announces a public meeting to receive comment on these proposed standards and associated analyses and results.
- DOE will accept comments, data, and information regarding this NOPR until April 3, 2023.
- Interested persons may submit comments identified by docket number EERE–2020–BT–STD-0006, by email (EPS2020STD006@ee.doe.gov), Federal eRulemaking portal (http://www.regulations.gov).
- DOE will hold a webinar on Wednesday, March 1, 2023, from 1:00 p.m. to 4:00 p.m.

- Foreign Nationals interested in participating in this webinar, must be screened by DOE Headquarters Security prior to being granted access. Please email Regina.Washington@ee.doe.gov to complete the necessary documentation at least two weeks prior to scheduled meeting date.
- Additional webinar registration information, participant instructions, and information about the capabilities available to webinar participants will be published on DOE’s website: https://energy.gov/eere/buildings/public-meetings-and-comment-deadlines

Current Standard
External power supplies manufactured and distributed in commerce, as defined by 42 U.S.C. 6291(16), must meet the energy conservation standards specified in the Code of Federal Regulations at 10 CFR 430.32(w).
To determine that external power supplies that are currently manufactured or distributed into commerce are in compliance with DOE standards, manufacturers must follow the test procedure methods specified at 10 CFR 430, Subpart B, Appendix Z.
