Trump Blocks Foreign Grid Equipment Over Security Risks

Large transformers and control systems are critical to the U.S. power grid, with long replacement cycles and a concentrated supplier base. Concerns that embedded chips or firmware could provide a hidden route for disruption have elevated equipment sourcing into a national-security issue. The stakes have risen as artificial-intelligence data centers and cryptocurrency miners drive up electricity demand, making reliable power central to the race for advanced computing capacity.

President Donald Trump signed a national emergency executive order barring purchases of specified foreign-made equipment for the backbone power system, targeting products that may contain Chinese chips vulnerable to security backdoors. The administration has not disclosed a complete list of restricted equipment, the value of affected procurement or a detailed implementation timetable. Additional screening and supplier changes could delay grid upgrades and constrain the expansion of AI data centers and mining operations.
