Check the boxes above to view the routes PSE is currently considering, as well as photo simulations of the preferred route, Willow 2.

PSE is currently considering multiple route options: Oak 1, Willow 1, Oak 2 and Willow 2. PSE's preferred route is Willow 2. PSE also submitted two 'bypass' route options to be evaluated in the EIS. These routes were developed in order to minimize the risk of a potential project delay due to permitting.

PSE prefers to use the existing transmission line corridor. However, it's our responsibility to keep the lights on and we must measure and address permitting risks to the project in an effort to keep Energize Eastside on schedule.
