Bonneville Power Administration (BPA) will continue emergency maintenance and repair activities needed along two high voltage transmission lines affected by forest fires in Multnomah and Hood River counties, Oregon. The Eagle Creek fire started on September 2nd, 2017 and burned approximately 49,000 acres, including through areas where BPA owns and operates the 115-kV Bonneville-Hood River transmission line—which runs from the Bonneville Dam powerhouse in Multnomah County, Oregon, to Hood River Substation in Hood River County, Oregon—and the 500- kV Knight-Ostrander transmission line, which runs from Knight Substation in Klickitat County, WA, to Ostrander Substation in Clackamas County, Oregon. Both of these transmission lines are critical components to the Northwest’s transmission system.
