Northern Wasco PUD

NIA Substation Transmission-Feeders

The design consisted of engineering and preparation of written specifications, bill of materials and drawings for a Project as described as below:

The first component of the Project, (“Interim Service Lines”) consisted approximately 0.15 mile of two (2) parallel, 13.8 kV double-circuit, three-phase, overhead distribution lines. At one deadend, the risers and conduit were installed for underground cable. This component of the Project crossed Rivertrail Way, near the BPA Chenoweth Substation, in the Columbia Gorge Industrial Center, The Dalles, and Wasco County, Oregon. Each of the two, double circuit lines must have a capacity of 33 MVA.

The second component of the Project (“Temporary Power Line”) consisted approximately 450 feet of 13.8 kV single-circuit, three-phase, overhead distribution line. At the source deadend, a riser and conduit were installed for underground cable. This component was located along the north side of Rivertrail Way, near the BPA Chenoweth Substation, in the Columbia Gorge Industrial Center, The Dalles, and Wasco County, Oregon. This circuit must have a capacity of 10 MVA.
