President Trump’s measure is not a blanket ban on foreign-made equipment across the entire U.S. power grid. The key point is that, for large-scale power systems—including transmission lines rated at 69 kV or more—the Department of Energy may assess the risks posed by foreign-made electrical equipment and related digital elements to national security and grid reliability, and restrict transactions and operations accordingly. Local distribution facilities are excluded from the scope.
Key Changes
On August 26, 2026, President Trump determined that the supply of foreign-made electrical equipment for large-scale power systems constituted an unusual and extraordinary threat to U.S. national security, foreign policy, and the economy, and declared a national emergency. The executive order applies to transactions initiated after its issuance and authorizes the Secretary of Energy to prohibit the acquisition, importation, transfer, or installation of covered equipment when a foreign government or foreign national has an interest and the Secretary determines that the transaction poses a risk.
The scope extends beyond basic power infrastructure. Listed equipment includes substation transformers, grid-interactive inverters, battery energy storage systems, high-voltage circuit breakers, protective relays and metering equipment, generators, turbines, and industrial control systems. Critical components, software, firmware, digital services, maintenance services, and remote-access functions may also be subject to review.
The key standard is not simply whether equipment is foreign-made, but whether the transaction and equipment have been determined to pose a risk within a large-scale power system.
Current Status
The risk criteria set out in the executive order include sabotage, subversion, unauthorized access, malicious remote manipulation, and supply disruption. The order also identifies the potential for catastrophic effects on U.S. critical infrastructure and the economy, as well as unacceptable risks to U.S. national security or personal safety.
Accordingly, the executive order alone does not mean that all foreign-made power equipment has been immediately and completely banned. Nor can it be assumed that every company or entity from a particular country has automatically become subject to sanctions. The Secretary of Energy may designate specific countries, individuals, or equipment as a “Covered Foreign Entity” or as high-risk, and may establish separate authorization procedures or lists of prequalified equipment and suppliers.
The scope of application also requires careful distinction. The large-scale power systems covered by the order include generation, transmission, substations, and related equipment, while ordinary local distribution facilities are excluded. In other words, the phrase “the entire U.S. power grid” does not adequately describe the actual scope of the measure.
Impact
Equipment that has already been installed or acquired may also become subject to future management requirements. The Secretary of Energy may impose conditions on its continued use, operation, maintenance, or updating and, if deemed necessary, require the equipment to be identified, isolated, monitored, secured, disconnected, replaced, or removed. This does not mean that all existing equipment will be uniformly replaced or dismantled; the measures may vary according to risk levels and operating conditions.
The measure addresses the risks of large-scale power system equipment involving foreign interests in a way similar to Executive Order 13920 from the first Trump administration in 2020. However, the detailed equipment lists and authorization and exemption criteria under the 2026 order remain to be established through subsequent rules.
The growth in electricity demand from AI data centers can be viewed as part of the broader context making grid security and supply-chain discussions increasingly important. The International Energy Agency projects that global data-center electricity consumption will rise from approximately 460 TWh in 2024 to more than 1,000 TWh by 2030, and identifies the United States as a region where data-center electricity demand is expected to grow particularly rapidly. However, increased electricity demand from AI data centers has not been confirmed as the sole direct cause of this executive order.
What to Watch Next
The executive order directs the Secretary of Energy to issue the implementation rules and regulations deemed necessary within 120 days of its issuance. The following matters may be clarified in the rules released later:
- Which countries, individuals, and equipment will be designated as high-risk or as a Covered Foreign Entity
- How risk-assessment standards will be applied to equipment, software, firmware, and remote-access functions
- How transaction bans, separate authorizations, conditional operations, and exemptions will be distinguished
- What identification, monitoring, security-enhancement, disconnection, and replacement standards will apply to equipment that has already been installed
The conclusion currently supported by the available information is clear: the measure creates a framework for restricting transactions and operations involving risky equipment, centered on large-scale power systems of 69 kV or more. To determine which equipment and suppliers will actually be restricted, it will be necessary to review the Department of Energy’s subsequent rules and designations.
