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.
Some segments completed; others delayed for over a decade by environmental review and routing disputes.
Became a model for phased transmission development with ongoing public engagement.
The closest precedent to Blueprint South: a 500-kV line from the same utility parent navigating rural routing conflicts.
