Beaumeade - NIVO 230kV Double-Circuit Line

Dominion has completed the construction of the Beaumeade to NIVO underground 230 kV transmission line.

Project Description

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.
