Idaho Power proposes to construct, operate and maintain a new electric transmission line (single circuit 500 kilovolt) from the Boardman Substation near Boardman, Oregon to the new Hemingway Substation near Murphy, Idaho—known as the Boardman to Hemingway Transmission Line Project or B2H.
The Boardman to Hemingway Transmission Line Project is being proposed by Idaho Power to:
- Reduce constraints on the Northwest’s transmission system as customer demand for energy continues to grow.
- Increase transmission capacity.
- Improve system reliability.
- Ensure Idaho Power’s ability to provide future service for its customers as well as other utility customers in Idaho and Oregon.
The location of the proposed transmission line corridor has not yet been determined. Many ideas have been proposed and more will be forthcoming during and following Idaho Power’s Community Advisory Process, through additional public involvement, data collection and analyses conducted by the Bureau of Land Management (BLM), and through the Oregon energy facility siting process.
The project will also undergo an environmental review and permitting process to meet state and federal requirements.

This Web site is a collaboration between Idaho Power, the BLM, the U.S. Forest Service (USFS) and the Oregon Department of Energy-Energy Facility Siting Council (ODOE-EFSC).
This is the one-stop place to find project information from the agencies and Idaho Power. To learn how to participate in the project, view our Public Involvement page.
