Boise Load Addition
- Location Washington
- TimelineFebruary 2019 - May 2021
Michels Power, Inc. was contracted to expand two Pacific Power substations, Wallula and Cascade Kraft, to accommodate for the increased load required by the Boise Paper Mill and update the Wallula substation which was at capacity.
At the Wallula substation, Michels Power added a new 230-69kV bay by installing a 230-69kV 150 MVA transformer and tying into the existing 230kV bus. Crews also replaced one of the existing 60 MVA 230-69kV transformer with a new 150 MVA transformer, demolished the second existing 230-69kV 60 MVA transformer bay, and replaced the existing 230kV bus switches.
At the Cascade Kraft substation, Michels Power added a new bay to the substation within the Boise Paper Mill, installed a new 69-12.47kV transformer, and paved the entire yard to prevent sawdust buildup which could create an electrical hazard.
