The Trump administration has canceled a Biden-era effort to speed up power line construction by declining to designate three National Interest Electric Transmission Corridors (priority zones for transmission permitting). The Energy Department said the move ends a process that could have helped fast-track power line buildout in parts of Pennsylvania, Colorado, New Mexico, Oklahoma, Nebraska, North Dakota and South Dakota, along with five Native American reservations, by allowing federal regulators to issue permits if states moved too slowly or denied projects. The department framed the earlier push as part of a "Green New Scam agenda," while environmental advocates said blocking the corridors could weaken the electric grid and raise power costs at a time when much of the new generation seeking grid access is renewable.
