Hornertown–Hathaway
Overview
We are rebuilding an aging electric transmission line between Roanoke Rapids and Rocky Mount, North Carolina, in Halifax and Nash counties. After nearly six decades of dependable service, the lines’ structures and components are at the end of their service life. Replacing this equipment will maintain reliability and grid integrity for our customers.
The approximately 28.9-mile, 230 kilovolt (kV) electric transmission line between our Hornertown and Hathaway substations was built primarily on wooden H-frame structures. The new structures will be weathering steel H-frames. No new or expanded right of way is needed.
Benefits
- Maintains current right of way
- New structures located in the same general location as existing structures
- Complies with mandatory standards to ensure safety, reliability and to meet future needs
- Minimizes impact to the community and environment
- Replaces aging infrastructure
- Strengthens area reliability

The line was built primarily on wooden H-frame structures. We will rebuild this line using weathering steel H-frame structures. You can see examples of these structures on the Overview tab.
Our forestry team will survey area trees to identify danger trees that need removal. Danger trees are trees outside the right of way, and possibly on your property, that have the potential to fall within 10 feet of the transmission wires or structures. Trees and tree limbs that come in contact with electric lines are a leading cause of power outages, especially during storms. The removal of danger trees is necessary to help prevent large scale outages in your community.
If we need to access your property, our forestry team or authorized contractors will contact you. We are committed to working safely and courteously on your property. If you have questions or concerns about the right of way corridor, please email etrow@dominionenergy.com or call 800-215-8032.
We use a combination of traditional wooden matting to protect wetland vegetation and, where appropriate, the Emtek® wetland access system. This floating mat system allows our equipment to safely work on structures while protecting the vegetation beneath.
We also invite you to read our Corporate Environmental Policy and our Greenhouse Gas Report. Our enterprise-wide environmental report describes our commitment to the responsible stewardship of natural resources and provides a wealth of information on environmental management and performance.
We are rebuilding several electric transmission lines in North Carolina. Visit our Project Map and select North Carolina. The map will show a list of projects alongside their locations.
