| Summary | A Presidential determination issued on April 20, 2026, found that grid infrastructure supply chains, including distribution transformers and electrical core steel, are essential to national defense, and that U.S. industry faces critical constraints from limited domestic product capacity, extended procurement timelines, and foreign supply dependence. The U.S. Department of Energy ("DOE") is initiating an information and data gathering effort to understand how the energy conservation standards for distribution transformers adopted in an April 2024 final rule, with compliance required in 2029, interact with these national security considerations, including impacts on domestic manufacturing capa |
