The PUD began working with the community in 2015 to find a location for a new substation in the Leavenworth area to support growth and development in the Upper Valley. The existing double-bank substation serving this area is nearing capacity. The new substation is being planned at the intersection of Chumstick Highway and North Road. The decision was made based on input from the community focus group, the general public, PUD staff's engineering analysis and the consultant's feasibility report. The PUD is working with stakeholders in the vicinity of the site on substation design variables such as landscaping, fencing, lighting and more.
Two new transmission lines are needed to create redundant feeds to the new and existing substations to increase reliability for the Leavenworth area. One line is being planned between the existing Leavenworth substation, traveling north along Chumstick Highway and the second line is being planned in the Fox Road and North Road areas. The PUD worked with stakeholders in the area to gather input on three route alternatives for the second line. Based on public input and the feasibility analysis, PUD staff will move forward with design on the southernmost alternative (Alt. 3).
PUD staff is currently working on the design of the substation and transmission line routes. Staff anticipates submitting permit-level design to Chelan County to initiate the Conditional Use Permitting (CUP) process in spring of 2018. Staff will continue to work with stakeholders on the design of the substation and will notify all stakeholders before submitting the CUP.
We will continue to update our website and our outreach efforts via email and direct mail will continue as we move into the next phase of this project.
