  • April 2020 – Sent project update
  • August 2020 - Crews completing preliminary field reviews for construction start in October


  • Upgrades it to current 115 kilovolt (kV) electrical safety and clearance standards
  • Requires no new permanent right of way
  • Utilizes similar structure design as the existing corridor conditions

After more than six decades of operation, the wooden H-frame structures and associated components along the nearly 23-mile line running between our Staunton and Harrisonburg substations need to be replaced. This line runs through Staunton City, Augusta County, and Rockingham County, and serves more than 7,500 customers. Almost half of these customers are powered by two Shenandoah Valley Electric Cooperative substations served by this line.

Overview & Project Description

The Staunton-Harrisonburg 115 kV line was originally built in 1958 using wooden H-frame structures. Although the line and its components have been well-maintained, they are at the end of their service life and need to be replaced to maintain reliability for over 7,500 customers served by Dominion Energy and Shenandoah Valley Electric Cooperative substations along the corridor. The line was originally constructed using wooden H-frames and will likely be replaced with weathering steel H-frames and monopole structures.

Existing Transmission Corridor Conditions

  • Project area is 22.8 miles long
  • Right of way width is primarily 100 feet wide with some 150-foot sections
  • Average structure height is 53.4 feet
  • 205 structures in the corridor

Proposed Transmission Corridor Conditions

  • Weathering steel H-frame structures
  • Utilizes existing right of way corridor
  • Average proposed structure height is 66 feet


  • June 2019 - Project announcement postcard sent to neighbors
