Boardman to Hemingway Transmission Line Project - Home

The federal agencies are continuing to develop the draft EIS, which is scheduled for release on October 24, 2014. The draft EIS will include documentation of environmental effects for all alternatives analyzed. ODOE is currently reviewing Idaho Power's preliminary Application for Site Certificate.

Idaho Power has coordinated a Community Advisory Process, is analyzing the project’s engineering requirements, and will coordinate right-of-way acquisition, construction and operation.

The Bureau of Land Management (BLM) is leading the federal environmental review and permitting process according to the National Environmental Policy Act (NEPA).

The Oregon Department of Energy (ODOE) is leading the state review process to obtain a Site Certificate from the Energy Facility Siting Council (EFSC).


Idaho Power has requested a right-of-way grant from the BLM, a special-use permit from the US Forest Service (USFS), and a site certificate from ODOE to construct, operate, and maintain a new 500 kilovolt, single-circuit electric transmission line from a proposed substation in NE Oregon to the Hemingway Substation in SW Idaho—known as the Boardman to Hemingway Transmission Line Project or B2H Project. PacifiCorp and Bonneville Power Administration are funding partners of the NEPA, ODOE, and related permitting processes.

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.
