Energize Eastside

In 2013, PSE announced the need for an upgrade to the Eastside's power grid, citing this population increase.

[1][2] PSE ultimately selected to upgrade the existing corridor, known as "Willow 1" rather than use a parallel one owned by Seattle City Light or use alternatives such as batteries.

[1] The project has encountered significant controversy from the beginning, especially from the Coalition of Eastside Neighborhoods for Sensible Energy (CENSE).

The new 230 kV power lines require a larger easement and 20-40 feet taller transmission towers.

Opponents of the project argue that PSE has overstated the need for new power lines, using the most generous forecasts of electric demand.

[1][8] PSE has responded to these claims by citing several independent studies that power demand will surpass the capacity of the existing lines.

[2][9] As part of the permitting process, PSE is required to create a specific safety plan with Olympic.

It then enters the city of Redmond, passing over Rose Hill Middle school before ending at the Sammamish substation.
