Pacific Power moves Oregon transmission line east after public pushback

Pacific Power moves Oregon transmission line east after public pushback

Built World

Utility shifts 180-mile line into a rural corridor; some residents remain split

Today: Route M named preferred corridor

Overview

Updated 2 hours ago

Pacific Power has moved its preferred route for a 180-mile transmission line east, away from subdivisions near Bend, after a year of community opposition. The new Route M runs through a more rural corridor across Crook, Deschutes, Lake, and Klamath counties, from a proposed substation near Prineville to an existing connection near Klamath Falls.

The 500-kilovolt line is designed to ease grid congestion and move renewable energy across south-central Oregon. Route M is preliminary, and PacifiCorp says it could change before the routing study concludes this year. Some Powell Butte residents welcome the shift; others were told the line could come within half a mile of their homes.

Why it matters

This line determines how Oregon's renewable energy reaches the grid for decades, and whether rural residents near Bend live next to 180-foot towers.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

2008-present

Gateway West transmission line (2008-present)

A roughly 1,000-mile, 500-kV transmission line proposed across Idaho and Wyoming by Rocky Mountain Power, a PacifiCorp brand. Routing was revised multiple times in response to concerns about scenic views, sage grouse habitat, and local opposition.

Then

Some segments completed; others delayed for over a decade by environmental review and routing disputes.

Now

Became a model for phased transmission development with ongoing public engagement.

Why this matters now

The closest precedent to Blueprint South: a 500-kV line from the same utility parent navigating rural routing conflicts.

2014-2020

Atlantic Coast Pipeline (2014-2020)

Duke Energy and Dominion Energy planned a 600-mile natural gas pipeline through West Virginia, Virginia, and North Carolina. Legal challenges over the Appalachian Trail crossing and environmental permits drove mounting delays and cost overruns.

Then

The companies cancelled the project in July 2020 after years of litigation.

Now

Showed that cumulative legal opposition can kill an infrastructure project entirely.

Why this matters now

A reminder that routing opposition, if it persists through litigation, can end a project.

2014-2024

Mountain Valley Pipeline (2014-2024)

A 303-mile natural gas pipeline from West Virginia to Virginia. Legal challenges over water crossings and federal permits halted construction repeatedly. The 2023 Fiscal Responsibility Act directed agencies to approve remaining permits, and the pipeline was completed in June 2024.

Then

Construction finished after years of delays and cost increases.

Now

Set a precedent for Congress overriding environmental review to speed energy infrastructure.

Why this matters now

Shows how permitting and legal challenges can stretch a major energy project into a decade-long fight.
