Executive Order 14421 declares a national emergency over bulk-power system equipment — barring acquisition, import and installation of gear tied to covered foreign entities at 69 kV and above — Federal Register (August 2026)

1The hardware of the grid becomes a security question

Executive Order 14421, published in the Federal Register on August 31, 2026, finds the foreign supply of bulk-power system electric equipment itself to be an unusual and extraordinary threat to U.S. national security, foreign policy and the economy.

It is a declaration of national emergency under the International Emergency Economic Powers Act, and it reaches not only individual transactions but transactions considered as a class. The concern the order names is concrete: equipment that might have digital backdoors built in, allowing a foreign country to reach it remotely.

It also cites supply chain vulnerability — that reliance on foreign sources could eliminate the supply outright through disruptions in international trade or other causes.

2What triggers it, and what follows

1. 1DeterminationThe Secretary of Energy, coordinating with OMB and consulting the Secretaries of War, Commerce and Homeland Security and the DNI, makes the finding
2. 2ProhibitionAcquisition, importation, transfer or installation is barred where a Covered Foreign Entity designed, developed, manufactured or supplied the equipment and the transaction poses undue risk of sabotage, unauthorized access or supply disruption
3. 3Existing equipmentConditions may be imposed on equipment acquired or installed before the order, including identifying, isolating, monitoring, securing, disconnecting, replacing or removing it
4. 4SafeguardBefore directing isolation, disconnection, replacement or removal, the Secretary weighs reliability and safety, the availability of secure replacements and continuity of essential service, and may set phased compliance
5. 5Within 120 daysThe Secretary publishes rules or regulations implementing the delegated authorities
6. 6Within 180 daysThe Secretary submits recommended revisions to the Federal Acquisition Regulation so that security risks are weighed in federal energy infrastructure procurement and U.S.-manufactured equipment is prioritized

One provision worth noting is pre-qualification. The Secretary may establish criteria for recognizing particular equipment and vendors as pre-qualified for future transactions, and publish that list. The design does not only draw a line of prohibition; it also marks out a route through.

3Where the boundaries are drawn

The order defines its terms closely. The bulk-power system includes transmission lines rated at 69,000 volts or more but excludes facilities used in local distribution of electricity.

The equipment named includes substation transformers, utility-scale and grid-connected inverters, battery energy storage systems, uninterruptible power supplies supporting critical infrastructure, high voltage circuit breakers, generation turbines, protective relaying, metering equipment, and industrial control systems including remote terminal units, programmable logic controllers and intelligent electronic devices.

Associated software and firmware, remote access capabilities and lifecycle maintenance and update mechanisms may also be considered.

A Covered Foreign Entity means a country, or a person owned by, controlled by or subject to the jurisdiction or direction of a government subject to a U.S. arms embargo or sanctions regime under the International Traffic in Arms Regulations (22 CFR 126.1), or one the Secretary determines is engaged in conduct detrimental to U.S. national security or foreign policy.

4Why the scope widened now

The order states its own reasoning. Rapid growth in advanced manufacturing, data centers, artificial intelligence and defense production has deepened the nation's dependence on abundant, reliable electricity and magnified the consequences of a successful attack or supply disruption.

Discussion of AI infrastructure gravitates toward compute and semiconductors; here the question of where the grid hardware underneath was built is raised to the level of a declared emergency. Of the 6,830 Federal Register documents this site holds as of 2026-09-02, only 66 are presidential documents, against 920 rules and 5,384 notices. Few in number, they work as the origin point that sets subordinate rulemaking in motion.
