Trump on Wednesday signed an emergency executive order, citing national security, that prohibits US procurement or installation of certain foreign-made large power-system equipment and related software judged to pose cybersecurity or operational risks, including transformers. The order empowers the energy secretary to impose restrictions on already-installed equipment where necessary and directs the Department of Energy to issue implementing rules within 120 days; it excludes local distribution

Trump on Wednesday signed an emergency executive order, citing national security, that prohibits US procurement or installation of certain foreign-made large power-system equipment and related software judged to pose cybersecurity or operational risks, including transformers. The order empowers the energy secretary to impose restrictions on already-installed equipment where necessary and directs the Department of Energy to issue implementing rules within 120 days; it excludes local distribution facilities. The measure could benefit US electrical-equipment manufacturers, including SolarEdge, Enphase Energy and Tesla (TSLA.O).
