President Donald Trump signed Executive Order 14420 on Wednesday, declaring a national emergency regarding the security of the U.S. bulk power system.
The executive order aims to block foreign-made bulk-power system equipment — including critical software, firmware and remote-access capabilities — from being purchased or installed in the U.S.
The Department of Energy has 120 days, roughly until Dec. 24, to finalize implementing rules and identify specific banned equipment or suppliers, per Reuters.
The order covers large substation transformers, utility-scale and grid-connected inverters, battery energy storage systems, high-voltage circuit breakers and industrial control systems, but excludes local electric distribution facilities.
Trump’s order targets transactions tied to nations under U.S. arms embargoes or sanctions — a list of roughly two dozen countries that is not named explicitly in the text but is widely read as aimed primarily at China, according to Reuters.
The move follows bipartisan concern over cybersecurity vulnerabilities in Chinese-made grid components, as well as a series of cyberattacks on U.S. water facilities, heightening scrutiny of critical infrastructure.
Domestic manufacturers and onshore suppliers could see increased demand as utilities move away from foreign vendors ahead of the DOE’s rulemaking deadline:
Broader market weakness weighed on all four names in Friday’s session, but Trump’s executive order sets up a multi-month catalyst window as DOE rulemaking unfolds through year-end.
