To meet Prince William County’s growing energy demands and comply with federal reliability mandates, we are proposing to upgrade equipment at the existing Vint Hill Substation located at 13405 Vint Hill Road in Nokesville, Virginia.

This project will add 500 kV equipment and new 230 kV infrastructure. We plan to install 500 kV transformers and related equipment as well as modern Gas Insulated Substation (GIS) technology.

To accommodate the new equipment, we will expand the footprint of the substation on Dominion Energy-owned property. No new permanent electrical easements will be required to support this expansion project

We have submitted an application for a Special Use Permit to Prince William County for the project; we will seek approval over the coming months. Pending permits and approvals, we anticipate beginning construction in Spring 2026.
