March 2020 – Project announcement sent to neighbors
Summer 2021 – Begin construction
End of 2023 – Complete project
The line is at the end of its service life and needs to be replaced to maintain reliability for our customers.
- Project Informational Meeting – TBA
Our suggested approach is to rebuild this line in a manner that:
- Upgrades it to current 115 kilovolt (kV) standards
- Utilizes the existing right of way with minimal exceptions
- Uses brown, weathering steel H-frames and monopoles
Two 115 kilovolt (kV) transmission lines were built in the 1920s with a combination of steel lattice structures and wooden H-frames in the 9.2-mile right of way corridor that runs through Rockbridge, Amherst, and Bedford counties. Both electric transmission circuits begin at our Balcony Falls Substation in Rockbridge County. They primarily share the same structures until they reach Cushaw Substation at the hydroelectric generation facility in Amherst County. From there, one circuit continues to Skimmer Substation in Bedford County.
The existing wooden H-frame and steel lattice structures will be replaced with a combination of brown, weathering steel H-frame and steel pole structures.
The key purpose of this project is to replace old infrastructure and rebuild to current reliability standards.
Existing Transmission Corridor Conditions:
- Project area is 9.2 miles long
- Right of way width is primarily 125 feet wide with some 100-foot sections
- Average H-frame structure height is 46 feet
- Average lattice structure height is 80 feet
- 85 structures in the corridor
Proposed Transmission Corridor Conditions
- Average proposed H-frame structure height is 56 feet
- Average monopole structure height is 92 feet
- 69 total structures in proposed corridor
- Maximum structure height increase of 63 feet in Balcony Falls-Cushaw section.
- Maximum structure height increase of 17 feet in Cushaw-Skimmer section
