Oregon Regulator Approves Segment of Boardman to Hemingway Transmission Line
Oregon’s Energy Facility Siting Council on Tuesday approved a site certificate for the Boardman to Hemingway (B2H) transmission line.
The permit, once finalized, will authorize construction of the 290-mile, 500-kilovolt line across five eastern Oregon counties. Federal agencies have already granted permission for the line to cross land they manage.
B2H will connect a new station near Boardman, Oregon, to Idaho Power’s existing Hemingway Substation in southwest Idaho. It will provide a crucial link to move energy, much of it from hydroelectric, wind and other clean sources, between the Pacific Northwest, where energy use peaks in the winter, and the Intermountain West, where energy use peaks in the summer.
Existing connections between the two regions are full — they can’t carry any more power during peak periods. Industry experts, environmental groups and government agencies agree that building more high-voltage transmission lines is crucial to incorporating a growing amount of clean energy on the grid. B2H will help Idaho Power pursue its goal of providing 100% clean energy by 2045. It will also support the clean energy goals of other energy providers in the West.
B2H’s site certificate follows a multi-year process in which residents, tribes, local governments, the federal government, interest groups and other stakeholders provided input on the project.
