Dominion Energy Files Suit Over $100 Million Vint Hill Substation Plan
The utility argues Prince William County’s veto of the grid upgrade threatens regional reliability and seeks judicial review of the Board of Supervisors’ decision.

Dominion Energy has filed a lawsuit against Prince William County, challenging the local government’s decision to oppose a plan to overhaul an existing substation. The utility company is arguing that the Vint Hill substation project is needed to maintain regional grid reliability.
Dominion states that the Board of Supervisors’ decision warrants additional review. The suit marks a formal escalation in the dispute over the infrastructure upgrade, which the company contends is essential for the area’s power network.
The project involves a major upgrade to the Vint Hill substation. Dominion maintains that the county’s rejection of the plan could impact the stability of the local electrical grid. By taking the matter to court, the utility is seeking a legal determination on the county’s veto.
The lawsuit does not detail the specific financial costs of the project, but it centers on the operational necessity of the substation improvements. Dominion asserts that the current state of the infrastructure requires the proposed changes to ensure consistent power delivery to the region.
Prince William County officials have opposed the substation plan, leading Dominion to pursue this legal avenue. The utility’s filing suggests that the disagreement over the project’s scope and necessity cannot be resolved through administrative channels alone.
This legal action places the Vint Hill substation upgrade at the center of a jurisdictional conflict between the state utility and the local government. The court will now review whether the Board of Supervisors’ opposition to the project aligns with requirements for grid reliability.
