This is the line Identification on the pole. Puget Power (now Puget Sound Energy) use to ID their 55 and 110kv lines this way. I've figured out what a lot of them mean. This one is White River - Electron - 1, Pole 17 of Mile 2 It runs from the white river hydro plant to the Electron dam via Bonney Lake and Orting. There is also a branch that runs to the Krain Corner substation that is shown here [id=141245196]. I think there is a '1' on this ID because there is a 55kV line that runs from white river to krain corner via the other side of lake tapps. It has the tag of WR-E. It does eventually connect to Electron but feeds a branch to Cumberland, one to greenwater, and then runs to Buckley, Wilkeson, through Carbonado (no sub there), then to Electron.
