Background
When an existing substation is consistently reaching 80% capacity, it triggers the PUD to begin looking into the need for a new substation. The PUD refers to this as an 80/20 Model and it initiates the process of identifying a location for a new substation and the associated transmission and distribution lines, in order to continue resilient and reliable service.
Chelan County PUD has been working with the community since 2015 to construct a new substation and associated transmission lines to serve the Leavenworth area. The existing double-bank substation serving the area is nearing capacity. In May 2017, the PUD, along with community input, selected a site at the intersection of North Road and Chumstick Highway for the new substation.
