Donald Trump issued an executive order that restricts foreign-made electrical infrastructure across the United States bulk-power system, and the move is framed as Trump declares a national emergency around grid security. The order reaches transformers, utility-scale inverters, circuit breakers, energy storage systems, and industrial control electronics tied to substations, power generation facilities, and control rooms.
The order covers equipment connected to entities in 24 embargoed nations and applies to transactions initiated after Aug. 26, 2026. It also excludes residential or commercial distributed energy assets that connect only to local low-voltage distribution lines, narrowing the rules to higher-risk parts of the grid rather than every electricity customer.
Department of Energy rules
The Department of Energy has 120 days until Dec. 24, 2026 to publish formal rules implementing the policy. Norton Rose Fulbright said equipment is not formally barred until the Department of Energy evaluates specific vendors and issues official risk determinations, which means the order starts with a framework and ends with case-by-case screening.
The agency is also instructed to make recommendations to the National Security Council to isolate, monitor, or replace sensitive infrastructure as soon as practicable. For utilities and clean energy developers, the immediate practical question is not whether the order exists, but which products will be caught once the rulemaking turns the policy into an operational filter.
China, Iran, Russia, Syria
Iran, Russia, and Syria are among the affected nations, and China is described as the primary commercial supplier affected across solar, battery, and electrical component supply chains. The order also applies to transmission lines rated at 69 kV or higher and to generation assets necessary to maintain overall power system reliability, so the coverage reaches into core infrastructure rather than only specialized equipment.
The stated concern is remote access, cyber vulnerabilities, and grid disruption. That makes vendor review central: the executive order names the risk, but the Department of Energy must still decide which vendors and which pieces of equipment create that risk in practice.
Utilities and compliance
Utilities and clean energy developers already navigating Foreign Entity of Concern restrictions, domestic content rules, Section 45X manufacturing credits, and import tariffs now face another compliance layer. The next deadline that matters is Dec. 24, 2026, when the Department of Energy is due to publish the rules that will tell the market how to separate permitted supply from restricted supply.
Until then, procurement teams can see the direction of travel, but not the full map. The open question is which specific vendors or equipment lines the Department of Energy will designate as risky under the new framework.
