Ironbridge
Substation
Overview
We are making improvements to the Ironbridge Substation in Chesterfield County, Virginia to help maintain reliable service in the area.
This project includes expanding the substation and replacing aging infrastructure inside the substation and the security fence. The expansion will take place within Dominion Energy owned property.
Benefits
- Replaces aging infrastructure
- Strengthens area reliability

FAQs
A substation is a facility that changes voltage from high to low or from low to high, among other essential functions. When electric transmission lines enter a substation, the voltage is lowered using transformers. The lower voltage electricity is safely delivered to customers using electric distribution lines.
There are three primary drivers for this project:
- Aging infrastructure – Much of the equipment inside the substation is approaching the end of its service life and needs to be replaced to help maintain electric reliability.
- Load growth – Additional infrastructure is required in order to continue serving the present load, meet the network reliability criteria and prepare for anticipated load growth in the area.
- Safety regulations – The substation needs physical improvements for safety and reliability of service. An increase in space will allow us to maneuver inside the substation to access our equipment in a safe and efficient manner.
Interruptions to your electric service are not anticipated as a result of this project.
Construction for the project will not take place on Ironbridge Road and should not require the use of flaggers or VDOT permits.
