Dominion Energy plans to build 8.4 miles of new transmission infrastructure in the Ashburn and Dulles area to carry 500 kV and 230 kV powerlines to Data Center Alley. 

The proposed Golden to Mars transmission line (red) is part of a three-segment loop proposed by Dominion to move more power to data centers. 

Known as the Golden to Mars line, it is the last segment of a three-part loop to serve Data Center Alley, which connects with the Aspen to Golden line (under litigation) and the Wishing Star to Mars line. It also includes two offshoot 230 kV loops (Lockridge and Sojourner).
