Bonneville Power Administration to Improve Transmission Line

BPA completed the EA and FONSI and decided to proceed with the project. Activities include removing most of its existing Olympia Shelton No. 1 115-kV transmission line (structures and conductor) from Olympia Substation to Shelton Substation and replacing the last 14.5 miles of this line into Shelton Substation with a double-circuit 230-kV line on lattice steel towers. This will improve voltage stability during winter-peak load conditions on the Olympic Peninsula. The project is expected to be complete in fall 2009. For more information, go to
