About the project
Boardman to Hemingway, or “B2H,” is a proposed 500-kilovolt transmission line that will run approximately 290 miles across eastern Oregon and southwestern Idaho. It will connect the proposed Longhorn Substation four miles east of Boardman, Oregon, to Idaho Power’s existing Hemingway Substation in Owyhee County, Idaho.
Idaho Power is partnering with two other utilities, PacifiCorp and Bonneville Power Administration, to obtain permits for the project. Idaho Power, which is leading federal, state and local permitting efforts, has a 21 percent share of the project. BPA has a 24 percent share, and PacifiCorp has the remaining 55 percent.
What’s the schedule?
Idaho Power expects to finalize B2H permitting no later than 2021. Construction is expected to take three to four years. The line is planned to be in-service in 2026 or later.
