Check the boxes above to view the final route for Energize Eastside and photo simulations of the upgraded transmission lines.

PSE evaluated multiple route options and selected the existing corridor route because it is the least impactful route to Eastside communities.

PSE's decision was shaped by community input through the Community Advisory Group process, open houses, neighborhood and stakeholder briefings, detailed engineering analysis, the Cities' Environmental Impact Statement (EIS) process, property owner meetings, and nearly 3,000 comments and questions.
