Clark Civil is constructing an 8,400-square-foot gas-insulated substation (GIS) within the footprint of Dominion Energy’s active Idylwood Substation without interrupting service.

The new GIS will support increased capabilities despite limited available space. This project is a part of Dominion’s ongoing efforts to increase the resiliency of electrical service in Northern Virginia.
