Mt. Storm-Valley

At Dominion Energy, we are committed to continually reviewing and analyzing our energy infrastructure to provide the most safe and reliable electric service. We are currently exploring options to address an aging 500 kilovolt (kV) electric transmission line running from West Virginia into northwest Virginia. The line needs to be replaced to maintain reliability for our customers.

Open House Events

  • June 2018
    Augusta and Rockingham counties
    Dates TBD

Project Goals

  • Create no new right of way
  • Keep structures in the same general location as existing structures
  • Provide long-term reliability and durability without excessive maintenance
  • Complie with mandatory standards to ensure safety and reliability


This project will rebuild an existing 500 kV line located in West Virginia’s Grant, Hardy and Pendleton counties and Virginia’s Augusta and Rockingham counties that connects our Mt. Storm and Valley substations. The 64-mile line was built in 1965 and features brown, weathering steel lattice structures, which are nearing the end of their service life.


The line has been in operation for over five decades and needs to be replaced to ensure the integrity of the power grid and maintain reliability for our customers.

SCC Approval Process

The Virginia State Corporation Commission (SCC) has regulatory authority over all energy providers in Virginia and requires certification for all transmission lines out of the ordinary course of doing business or are at or above 138 kV. Among other responsibilities, the SCC validates the need for a proposed line and approves the route and structures. In reviewing a proposed project, the SCC must consider whether potential impacts on scenic assets, historic districts and the environment have been reasonably minimized.
