Puget Sound Energy electric transmission project

Baker River to Sedro-Woolley 115 kV transmission line project


Fall 2012 project complete
  • Construction on the south line began in May 2012 and was completed in October 2012. 
  • We completed construction of the north line in mid-July 2011.
Project overview

PSE rebuilt two 115 kilovolt electric transmission lines between the Baker River switching station, 3163 Baker River Road in Concrete, and the Sedro-Woolley substation, 24972 Minkler Lake Road in Sedro-Woolley. The project, called the Baker River to Sedro-Woolley 115 kilovolt transmission line project, entailed rebuilding on wood H-frame poles approximately 23 miles of transmission line on either side of our utility corridor.

Originally installed in 1927 and 1959, respectively, the existing Baker No. 1 and Baker No. 2 transmission lines were in need of replacement. By replacing the aging infrastructure with new poles and high-capacity wire, this project will increase the reliability of the electric system and help meet increasing demand for electricity in Skagit County.

What is a transmission line?

Transmission lines are key elements in the electrical distribution system. The lines safely transport high voltage electricity from power generation sources like dams and wind generating facilities to substations in local communities. Transmission normally takes place at voltages of 55 kV and higher.
