Harrowgate–Locks
115 kV Electric Transmission Rebuild Project
Overview

Dominion Energy is planning to rebuild an aging 115 kilovolt ( kV) electric transmission line between our Harrowgate Substation in Chesterfield County and Locks Substation in the City of Petersburg, Virginia. After nearly five decades of dependable service, the existing structures and components on the 5.4 mile line are at the end of their service life and need to be replaced. The line is built on wooden H-Frame structures. We are proposing to rebuild this line using weathering steel H-Frame structures. No new right of way is required.
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

Our forestry team will survey trees in the area 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.
Dominion Energy completes an evaluation of potential environmental, cultural and historical impacts of the project. We will work with local, state and federal agencies to complete these evaluations and mitigate any impacts. Permitting agencies on transmission line projects typically include the U.S. Army Corps of Engineers, the Virginia Department of Conservation and Recreation, the Virginia Marine Resources Commission, and the Virginia Department of Transportation. Commenting agencies include the Virginia Department of Game and Inland Fisheries and the Virginia Department of Historic Resources, among others. 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 also invite you to read our Corporate Environmental Policy and our Greenhouse Gas Report.
Yes. Existing easement agreements will allow us access to private roads crossed by the right of way. The company, at its expense, will repair any private roads damaged by Dominion Energy or its contractors during construction of the line or during future maintenance. In addition, we will reimburse property owners for crop damage, and repair or replace fences or gates if we damage them.
Interruption to your electric service is not anticipated as a result of this project.
