President Trump signed an executive order on August 26, 2026 declaring a national emergency over the security of the U.S. bulk-power system and banning the acquisition or installation of foreign-made equipment used to manage electricity transmission and generation, according to the order published by the White House and reporting by The Record. The order covers technology tied to transmission lines rated at 69,000 volts or higher, along with substations, control rooms, power generating stations and reactors, as well as associated software and firmware that could be remotely accessed or updated by foreign governments.
The administration said the action responds to a pattern of foreign actors “creating and exploiting vulnerabilities” in bulk-power system technology that could enable remote access or supply-chain disruptions. The order directs the Departments of Defense, Commerce and Energy to review transactions involving bulk-power equipment and calls for a published list of pre-qualified vendors and components that federal agencies and utilities can rely on going forward.
The order follows a string of confirmed intrusions into critical infrastructure operators this year, including cyberattacks affecting water utilities in multiple U.S. states and a reported multi-day shutdown of a small power plant in the United Kingdom, incidents that researchers have variously linked to Iranian, Russian and Chinese-linked hacking groups. For operators of power generation and transmission facilities, the order effectively elevates supply-chain vetting of grid control and monitoring equipment to the same priority long applied to physical perimeter security and access control systems protecting the same sites.
