Nimbus 230 kV Delivery
This 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 eastern Loudoun County has resulted in the need to build a new transmission line and sub station. 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.
Benefits
- Complies with mandatory standards to ensure safety, reliability and to meet future needs
- Minimizes impact to the community and environment

SCC
The Virginia State Corporation Commission (SCC) has regulatory authority over all energy providers in Virginia. 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.
On 2/23/22, Dominion Energy filed its application with the SCC. The SCC issued its Final Order approving the project on 10/14/22. Documents related to the case are available to the public on the SCC Docket of the SCC website or search by Case No. PUR-2022-00027 in the " Search Cases " section. In addition, interested parties may visit the SCC Case Comments Page where individual mailboxes are available for each case accepting public comments.
