Dominion has completed the construction of the Beaumeade to NIVO underground 230 kV transmission line.
In the Ashburn area of Loudoun County, new development is increasing electrical demand. Our existing Beaumeade substation is fully utilized and requires additional facilities and the Ashburn area requires an additional substation to meet the growing demand for power.
Dominion has expanded and added additional facilities to the Beaumeade substation located off Smith Switch Road near the W&OD Trail.
Dominion installed a 230 kV double circuit underground transmission line, approximately 2700 feet (0.5 mile±) long, from the existing Beaumeade substation to a new substation (NIVO) located near the intersection of Smith Switch Road and Chilum Place. This project was approved by the SCC as a qualifying pilot project under House Bill 1319.
The new NIVO substation is located at the DuPont Fabros Ashburn Corporate Center and serves the increase in electrical load due to construction of new data center facilities.
The Virginia State Corporation Commission (SCC) has regulatory authority over the need for the project, the route, and the environmental impact of electric transmission lines in Virginia. Typically, the SCC holds public hearings in the area, where anyone may address the SCC. If the findings of the SCC uphold the need for the line and route, the company is then required to comply with all applicable environmental state and federal laws.
