About Project Permitting

The U.S. Bureau of Land Management (BLM) released its Record of Decision (ROD) for the Boardman to Hemingway Transmission Line Project (B2H) on Nov. 17, 2017. The ROD allows BLM to grant right-of-way to Idaho Power for the construction, operation, and maintenance of the B2H Project on BLM-administered land. The approved route is the Agency Preferred Alternative identified in the Final Environmental Impact Statement (EIS) and Proposed Land-use Plan Amendments.

For all lands crossed in Oregon, Idaho Power must receive a site certificate from the Energy Facility Siting Council (EFSC) prior to constructing and operating the proposed transmission line. The Oregon Department of Energy (ODOE) is staff to EFSC and facilitates the review of the site certificate application process. ODOE and EFSC will review Idaho Power’s application for compliance with state energy facility siting standards.

The U.S. Forest Service (USFS) will issue a separate ROD for lands administered by the USFS based on the analysis in the Final EIS. Read more about the National Environmental Policy Act (NEPA) process on the federal process page.


PacifiCorp, Bonneville Power Administration (BPA), and Idaho Power jointly propose to design, construct, operate and maintain a new 500 kilovolt, single-circuit electric transmission line from a proposed substation near Boardman, Oregon to the Hemingway Substation near Melba, Idaho—known as the Boardman to Hemingway Transmission Line Project or B2H Project. Idaho Power is leading the permitting process for the Project.

The B2H Project would provide additional capacity for exchanging energy between the Pacific Northwest and the Intermountain West, depending on which region is experiencing the highest demand. The Project would also serve load, improve reliability, interconnect resources, and take advantage of seasonal and near-term load and generation diversity between regions. Visit Idaho Power's About the Project page for more information.

In 2010, following a year-long community advisory process, Idaho Power selected a proposed route for the transmission line. The project is now advancing through a federal review process under NEPA led by the BLM and a state review process led by the ODOE-EFSC. If approved by both the federal and state agencies, the final route would be selected from various alternatives and Idaho Power’s proposed route.
