A project rebuilding nine miles of the existing 115-kilovolt transmission line between the Hope Substation and the Summit Lake Substation is underway. The project got underway in January and is expected to be complete by April 1. It includes upgrading the line between Mile 46 and Mile 55 of the Seward Highway from 115 kV to 230 kV.
The existing line has reached the end of its useful life and needs to be replaced. The upgrade will improve reliability and increase the future power transfer capacity from the Kenai Peninsula to Anchorage.
Backcountry users and highway travelers are advised to keep an eye out for construction equipment operating in the right-of-way, disruption of trail surfaces, and increased truck traffic on the Seward Highway.
