Spacer Damper Replacement Program
​Bonneville Power Administration crews or contractors will be conducting maintenance work on transmission lines in the coming months. Spacer dampers are pieces of equipment that prevent high voltage transmission lines from touching one another. Over time they wear out and need to be replaced. The work is necessary to maintain system reliability and ensure the reliable transmission of high-voltage electricity. Maintenance crews will use existing access points and roads to enter the transmission right-of-way. The work requires the use of utility bucket trucks, and occasionally helicopters, to complete. There will be minimal if any interruption to local traffic as a result of this work.
​If you have any questions call BPA toll free at 1-800-622-4519.
