Possum Point
Substations and Transmission Line Reliability Project
To help maintain reliable electric service for your area and comply with federal safety standards, Dominion Energy is making improvements to the infrastructure around Possum Point Power Station in Prince William County, Virginia.
The project includes adding a transformer at an existing 500 kilovolt (kV) substation, improving an existing 230 kV substation, and installing nearly one mile of new transmission line in an existing line corridor. All work will be done on Dominion Energy property and have minimal impact on the local community.
