What is the Golden-to-Mars transmission line project?
Dominion Energy plans to build an 8.3 to 9.8‑mile double‑circuit line operating at 500 kV and 230 kV, connecting the Golden substation near Waxpool Road and Sully Road to the Mars substation near Old Ox Road and West Perimeter Road. This line will complete a loop that includes two other segments: Wishing Star-to-Mars and Aspen-to-Golden.

Community Concerns: Dominion has filed their application with the SCC (State Corporation Commission) proposing six high-voltage overhead transmission line route options that would bring 165-foot transmission towers within 500 ft of residences and public schools. The proposed routes can be viewed here: https://northernvaprojects.com/#close (filter: Loudoun County and Golden to Mars)

Environmental & Wildlife Impact:
Local conservation groups argue that overhead line construction would fragment remaining wildlife habitat—particularly along Broad Run stream corridors—and call for alternatives that minimize ecological harm.

Push for Undergrounding:
Loudoun County supports burying the lines where feasible and has urged the SCC to consider underground routing within 500 ft of residences or public schools, though the County cannot require it. The County is working with engineers to find an undergrounding solution that can be submitted during the SCC proceedings.

Take Action to Save our Community:
Our goal is to increase public awareness and encourage residents to submit comments to the SCC to keep high-voltage powerlines out of our neighborhoods and to support undergrounding.

Ongoing proceedings through the SCC—including hearings in September and October 2025—will shape whether the approved route is overhead or partially undergrounded, based on technical feasibility and public input.

We need to make our voice heard!
