Rebuild Pearl – Marion #1 500 kV transmission line and replace the 2.5” expanded conductor
Justification as BPA states it: Will create additional capacity to support regional load growth, reliability needs and commercial requests for long-term transmission
A planning bundle in BPA's Grid Expansion and Reinforcement Portfolio: status, expected energization and cost change with each cycle; not a permit, a contract or a route. Proposed line rebuilds and upgrades as BPA published them for its GERP cycle: expected energization year, estimated cost in dollars and status are BPA's planning figures at publication and change with each cycle; the geometry is the existing line the project follows, not a final route.
Map location unavailable. This plant remains part of the source inventory and tables.
