Executive Order 14420 Targets Foreign Bulk-Power and PLC Equipment

Detail

This is the most significant U.S. intervention in industrial control-system sourcing since the 2020 bulk-power order. Unlike earlier measures, it does not name a single supplier , it targets entire categories of equipment, which shifts the burden of proof onto buyers and vendors to demonstrate that their supply chains are clean.

President Trump grounded Executive Order 14420 in the International Emergency Economic Powers Act (IEEPA) and the National Emergencies Act. The White House describes foreign supply of bulk-power electric equipment as "an unusual and extraordinary threat" to national security, the economy, and foreign policy.

The order does not impose a blanket ban on all foreign-made products. Instead, it directs the Secretary of Energy to identify and prohibit specific transactions , acquisitions, imports, transfers, and installations , involving covered equipment from foreign adversaries and other covered foreign entities.

The definition of "bulk-power system electric equipment" is deliberately broad and includes:

Industrial control systems , including remote terminal units (RTUs), programmable logic controllers (PLCs), and intelligent electronic devices (IEDs)

The order's explicit inclusion of PLCs, RTUs, IEDs, DCS, and safety instrument systems reflects a sharp shift in Washington's view of industrial automation. Regulators no longer treat control hardware as neutral commercial technology; they see it as a potential remote-access vector for sabotage of critical infrastructure.

For industrial automation buyers, the implication is clear: a PLC or RTU with remote-access firmware, sourced from a covered foreign entity, could now fall within a prohibited transaction. Project timelines, vendor qualification, and lifecycle support decisions all carry new compliance weight.
