Executive Order 14421 expands scrutiny of foreign-made bulk-power equipment

Federal action declares a bulk-power supply-chain emergency

President Donald Trump signed Executive Order 14421 on August 26, 2026, declaring a national emergency related to the foreign supply of bulk-power system electric equipment. The order invokes the International Emergency Economic Powers Act and the National Emergencies Act, framing foreign equipment exposure as a potential source of sabotage, unauthorized access, malicious remote action and supply disruption.

The candidate record’s executive-order number requires correction. Although a White House page displays the same text under EO 14420, the signed order’s official Federal Register publication identifies it as EO 14421. EO 14420 is a separate August 10, 2026 order. For procurement and compliance records, the relevant citation is EO 14421, published August 31 at 91 FR 55995.

What equipment is within scope

The order applies to the bulk-power system: interconnected transmission-network facilities and control systems, plus generation needed to maintain electric-system reliability. For this order, transmission lines rated 69 kV or more are included, while facilities used in local electricity distribution are excluded.

Its equipment definition is broad. It expressly names substation transformers, grid-connected inverters, battery energy storage systems, generators, voltage regulators, relays, metering equipment, high-voltage circuit breakers, industrial control systems, remote terminal units, programmable logic controllers, intelligent electronic devices, distributed control systems and safety-instrumented systems. Associated software, firmware, remote-access functions, maintenance and update mechanisms, and other supply-chain dependencies can also be considered when they present an unacceptable risk.

The restriction is triggered by an agency risk determination

The order does not automatically ban every product made outside the United States. For a post-order transaction to be prohibited, it must involve foreign-produced bulk-power equipment connected to a foreign country or national, be designed, developed, manufactured or supplied by a person linked to a Covered Foreign Entity, and meet one of the order’s risk thresholds.

Those thresholds include undue risk of sabotage, subversion, unauthorized access, malicious remote action or supply disruption; catastrophic effects on critical infrastructure or the economy; or another unacceptable national-security or safety risk. A Covered Foreign Entity can include a country or person subject to a U.S. arms embargo or sanctions regime, as well as parties DOE identifies under the order’s process. DOE may also approve mitigation measures as a condition of allowing a transaction and establish a pre-qualification process for equipment and vendors.

Existing equipment can face conditions, but reliability is a stated consideration

DOE may impose conditions on foreign-manufactured or foreign-operated bulk-power equipment acquired or installed before August 26. Potential measures include identification, isolation, monitoring, securing, disconnection, replacement or removal. The department must consider reliability and safety, availability of secure replacements, and continuity of essential service before directing isolation, disconnection, replacement or removal; phased compliance is permitted.

That distinction matters for asset owners and project teams. The order creates authority and a review framework, but it does not itself identify a list of affected manufacturers, equipment models or countries, nor does it direct the immediate removal of a named class of installed equipment. Practical obligations will depend on future DOE determinations, rules, directives or licenses.

DOE and federal procurement actions are next

DOE must publish implementing rules or regulations as needed within 120 days of the order. Those measures may identify Covered Foreign Entities, equipment or countries requiring additional scrutiny, and procedures to license transactions that otherwise would be prohibited. DOE is also directed, as soon as practicable, to identify risk-bearing equipment and provide recommendations for its identification, inventory, isolation, monitoring or replacement.

Separately, DOE has 180 days to recommend Federal Acquisition Regulation revisions intended to ensure national-security risks are considered in federal energy-infrastructure procurement and to prioritize U.S.-manufactured energy infrastructure. The FAR Council then has 90 days after receiving those recommendations to consider proposing amendments for public comment. These are future rulemaking steps, not final FAR requirements today.

Procurement and engineering response

Organizations involved in transmission, generation and grid-connected energy projects should treat equipment provenance as more than a country-of-origin field. Bid packages, approved-vendor files and turnover documentation may need to capture where equipment was manufactured or assembled; ownership and jurisdictional ties of key suppliers; critical component sources; software and firmware provenance; remote-support arrangements; and update or maintenance dependencies.

For ongoing projects, procurement teams and integrators can identify bulk-power equipment already installed, on order or specified; preserve configuration and service records; and assess contractual flexibility if DOE later restricts a transaction or requires mitigation. Teams should avoid representing that a product is approved, exempt or prohibited unless and until DOE publishes the applicable determination or rule.
