Trump unleashes emergency powers to block foreign-made grid gear
President Trump signed an executive order declaring a national emergency and directing the Department of Energy to draft rules to secure the bulk-power system, including blocking or limiting foreign-made equipment such as transformers, batteries, inverters and related software; the order allows replacing installed foreign gear and sets a 120-day deadline for rulemaking, drawing industry comments on implementation and the need for clarity on software and covered-entity rules amid national-security concerns.
