Transmission Expansion Is a Reliability Planning Issue

Cross-border transmission is becoming more important to reliability planning. T&D World reports that the U.S. Department of Energy issued a Presidential Permit authorizing new transmission lines from North Dakota to the Canadian border. The project is expected to add up to 650 MW of transfer capability between the U.S. and Canada: https://www.tdworld.com/reliability-and-resiliency/news/55380306/doe-issues-basin-electric-presidential-permit-to-expand-uscanada-transmission-infrastructure For utilities and grid planners, this is not just an infrastructure expansion story. It reflects the growing need for transfer capability, regional coordination, and reliability planning as demand accelerates from AI, data centers, electrification, and changing resource needs. New transmission capacity can improve flexibility across regions, but it also adds planning complexity. Utilities must account for cross-border operations, capacity availability, compliance requirements, cost impacts, and how new infrastructure supports reliability under stressed system conditions. As the grid becomes more interconnected, infrastructure planning has to move beyond project approval alone. The focus shifts to how transmission investments strengthen resource access, support system resilience, and maintain reliability as load growth continues.
