Entiat Valley 115kv Transmission Line and Switch Yard

We constructed 5.6 miles of new 115kv transmission line.

The line originated from a new switchyard in Entiat and progressed west to a new substation in the Entiat Valley. A new switchyard was constructed near Earthquake Point, in Entiat, WA. The entire right of way occupies an ecologically sensitive area which mandated project coordination with multiple regulatory agencies, some hand excavation only sites, select logging and helicopter sets for 13 structures.


Agate Pass Tower Replacement

Replaced two existing steel lattice towers supporting two 115kv transmission lines crossing over the Agate Pass Waterway.

Set new steel poles and reconductor. Replaced towers with four steel poles, two on each side of Agate pass – Kitsap County side of the crossing replaced by two 130-foot tall steel poles; Bainbridge side replaced by two 140-foot tall steel poles.
