Boardman-Hemingway Transmission Line

Transmission paths are key to utilities like Idaho Power for bringing electricity into and through our service area.

To meet the need for more transmission capacity, Idaho Power plans to build a transmission line from northeast Oregon to southern Idaho. Idaho Power, together with the Oregon Department of Energy, Bureau of Land Management and U.S. Forest Service, has more information available on a project Web site. View our Project Fact Sheet .

Community Advisory Process

Idaho Power has established a community advisory process to help site the Boardman to Hemingway project. This process engages and includes members of the local communities from Boardman, Oregon to Murphy, Idaho. We are using teams in geographic locations to: 

  • Identify community issues and concerns
  • Develop a range of possible routes (while following all federal, state and local requirements)
  • Recommend proposed and alternate routes.

As we seek a solution to ensure a secure and comfortable lifestyle for generations to come, we will continue working with community members to gain feedback and ideas. This collaboration, and your active involvement throughout the environmental review process, will ultimately lead to the strongest solution.

For up-to-date information on the comprehensive public process to identify proposed and alternate routes for this project, we encourage you to visit the project Web site. Please note that there are no updated route or resource maps available at this time. Maps showing the initial route locations were provided during the scoping phase for the project (Fall 2008). The Web site will be updated as information, including maps, becomes available through the community advisory process.

Planning For The Future

Idaho Power’s Energy Plan for the Future, a biennially-produced 20-year resource plan for meeting our electric service obligation, identifies Pacific Northwest generation resources as one component of the preferred resource portfolio. Requirements of Idaho Power’s wholesale transmission customers are also increasing. The existing transmission system to the Pacific Northwest has been at full capacity during high-demand periods.

Several electric utilities, including Idaho Power, have proposed development of a transmission station near Boardman, Ore., which will serve as the Northwest source of the project. The Idaho terminal will be the Hemingway Substation located in the vicinity of Melba and Murphy on the south side of the Snake River. An additional substation eventually will be located northwest of Caldwell to improve performance of the long-distance transmission line.

Corridors will be developed or modified based on recommendations from the community advisory teams, studies of the area, comments from federal agencies and land owners, topography, access, and other factors.
