August 27, 2026 - President Donald Trump signed an executive order Wednesday aimed at limiting the use of certain foreign-made equipment in the U.S. electric grid, citing concerns about national security and the reliability of the country's energy infrastructure.

The order declares a national emergency related to the foreign supply of equipment used in the nation's bulk-power system. The White House said some imported components, along with their software and digital capabilities, could create cybersecurity and operational vulnerabilities.

Under the directive, certain foreign-produced electrical equipment considered a potential security risk will be prohibited from being purchased or installed in the United States. The restrictions apply not only to physical components but also to associated critical software and other digital technology.

The move is part of broader U.S. efforts to address potential security risks associated with foreign technology, particularly equipment originating in China. Similar concerns have emerged overseas. Earlier this year, the European Commission moved to prohibit Chinese-manufactured inverters from being used in publicly funded energy projects.

Security questions surrounding solar equipment have also drawn attention in the United States. In 2025, specialists examining some Chinese-made solar power inverters reportedly discovered undocumented communication devices inside the equipment. Such examinations are conducted to identify potential vulnerabilities in technology connected to electrical grids.

In his executive order, Trump said dependence on foreign sources for bulk-power electrical equipment represents an extraordinary threat originating substantially outside the United States. He cited potential consequences for national security, foreign policy and the U.S. economy as justification for declaring the emergency.

The directive also gives the U.S. Energy Secretary responsibility for addressing equipment already operating within the country's power system. The secretary may establish conditions governing the continued use of affected technology when the administration determines that security or operational concerns need to be addressed.

The White House said the measures are intended to reduce vulnerabilities within critical energy infrastructure and strengthen protections surrounding the nation's electric grid.
