The substation, along with new transmission infrastructure is needed to accommodate load growth and to maintain reliable electric service in the area. Rapid growth in electrical demand, particularly in the commercial/high-tech sector in Loudoun County has resulted in the need to build a new transmission line and substation. This project will improve electric reliability for all customers in the region.

At Dominion Energy, we are committed to reviewing and analyzing our energy infrastructure and doing this work safely to provide reliable electric service.

Three primary forces drive the need for new electric transmission infrastructure:

  • Economic development, such as population growth or business expansion
  • Aging assets, such as decades old structures that need to be replaced
  • Complying with mandatory standards to ensure safety and reliability

These drivers often overlap, and at Dominion Energy, we believe solutions should always account for future energy needs while continuing to balance cost and impacts.

Goals & Information

Recent

In September 2021, Dominion Energy plans to file an application for a Certificate of Public Convenience and Necessity (CPCN) with the Virginia State Corporation Commission (SCC).

Project Goals

  • Provide long-term reliability and durability without excessive maintenance
  • Deliver operational system flexibility to meet future needs
  • Comply with mandatory standards to ensure safety and reliability

Timeline:

  • July - September 2021: Outreach to the community

Overview

For this project, we will build new electrical equipment south of Dulles Airport near Route 50 in Loudoun County. This equipment will support the construction of a data center. In addition, we will build transmission lines to bring electricity to both a substation and data center

Proposed routes for this double circuit transmission line are estimated to be less than one mile and if approved, will connect the existing Poland Road Substation to the new Aviator Substation just east of Willard Road.

The project will include the installation of new steel structures.

SCC Approval Process

September 2021 - anticipated filing date for SCC application

The Virginia State Corporation Commission (SCC) has regulatory authority over all energy providers in Virginia and requires certification for all transmission lines out of the ordinary course of doing business or are at or above 138 kV. Among other responsibilities, the SCC validates the need for a proposed line and approves the route and structures. In reviewing a proposed project, the SCC must consider whether potential impacts on scenic assets, historic districts and the environment have been reasonably minimized.
