Loudoun - Ox
Project Overview
The Loudoun-Ox project will replace approximately 19 miles of 230 kV transmission line that has reached its end of service life and needs to be rebuilt to maintain electric reliability.
The project also includes the removal and retirement of several infrastructure assets thereby reducing the number of structures. The new structures will be rebuilt to current industry standards.

How can residents and business owners in the community become involved in this process?
There will be two open house events in summer 2019 where the public can meet with our subject matter experts to learn details on the project. In addition, the Transmission Application Process Chart outlines how the public can become involved in the Virginia SCC approval process. You can also contact us to add your mailing address and email address to our distribution list.
Will Dominion Energy propose placing this line underground or overhead?
Dominion Energy has more than 6,700 miles of overhead transmission lines. The proposed project seeks to replace existing overhead structures with new overhead structures within the existing right of way. In doing so, the line will be rebuilt to current safety and industry standards.
What will be the environmental impact of the line construction?
As part of the regulatory application process, Dominion Energy completes an evaluation of potential environmental, cultural and historical impacts of the project. Dominion Energy works with local, state and federal agencies to complete these evaluations and mitigate any impacts. All required permits are obtained and permitting conditions are met. Permitting agencies typically include the 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.
