What is a substation?

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.

Why is this project necessary?

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.

Will I lose power during construction?

Interruptions to your electric service are not anticipated as a result of this project.

Will there be any impacts to traffic during construction?

Construction for the project will not take place on Ironbridge Road and should not require the use of flaggers or VDOT permits.
