PGE is looking to expand its power line system in Portland's Forest Park along Highway 30, but the city opposed the environmental impacts to the area.

A Portland General Electric proposal to upgrade existing transmission lines in Forest Park would cut down too many trees, harm local efforts to combat climate change and fails to adequately consider alternatives,

PGE’s plans include shifting the location of one power pole and rewiring a segment of existing transmission line to it, and installing two poles to support a new 1,400-foot transmission line. Both the upgraded and new lines would run from just inside Forest Park, across Highway 30, to PGE’s Harborton substation on the Willamette River.
