Associated Ers (list all applicable):
This program is a foundational element of our overall effort to maintain the electric delivery system. While many of the assett management programs such as WPM, PCB transformers, Worst Feeders, URD
Cable replacement, are targeted efforts to maintain or improve reliability, this program specifically identifies thermal, voltage, and FDR tie issues amongst 345 individual electric circuits. This program
represents the collective effort of distribution planners and area engineers to manage our ability to serve customer load reliably, efficiently, and securely.
Distribution planning has identified a number of thermal constraints on the system where "segment
reconductor" work is warranted to mitigate thermally overloaded conductor. In addition, a number of
urban feeder tie additions are required to meet the Company's 500 Amp feeder plan also known as the
"feeder and one‐half" plan. This work is planned and coordinated with assistance from the five (5) Area
Engineers in Spokane, Big Bend, Colville, Coeur'd Alene, and Pullman. Annual spend varies from year to
year but the operational premise is constant: mitigate thermally overloaded conductor, mitigate known
or emerging voltage issues, and establish FDR tie points in compliance with the Company's 500A Feeder
Plan.
Annual Cost Summary ‐ Increase/(Decrease)
Unfunding segment reconductor and FDR tie program will result in thermally
overloaded conductor segments and significantly compromise the electric
distribution system. Loss of load service capacity would result.
