Mount Heron - Coal CreekTransmission Line Rebuild Project

Appalachian Power representatives announced plans in fall 2021 to upgrade the electric transmission grid in Buchanan and Tazewell counties. The project team has identified additional route options to build the transmission line and is seeking feedback from the community. The project involves:

  • Building about 4 miles of new transmission line
  • Rebuilding about 11 miles of transmission line
  • Retiring about 4 miles of transmission line
  • Retiring two substations
  • Building the Mount Heron Substation

Construction begins in early 2025 and concludes in fall 2026. 

Project Updates

May 5, 2023 - The project team has identified a new substation location and additional route options to build the transmission line. Landowners and community members are invited to a public open house to learn more about the project and provide input on route options. Since there is no formal presentation, residents may join the planned event at any time:

November 17, 2021 - The project team has determined a proposed power line route. The interactive map above shows the existing transmission line that crews plan to rebuild in or near the existing right-of-way. Note that the proposed line route as shown is subject to change during final engineering and after additional studies including, but not limited to, ground surveys, geotechnical and environmental studies, and additional interviews with landowners are completed. Directly impacted landowners can expect to hear about next steps from the right-of-way contractor representing Appalachian Power.

September 23, 2021 - Project representatives encourage landowners to submit their feedback about the project by Friday, October 22.
