Basin-Chesterfield
230 kV Electric Transmission Rebuild Project
The transmission line between our Basin and Chesterfield substations is approaching the end of its service life and must be rebuilt.
Project Details
- New generation needs to integrate with the electric transmission grid
- Existing infrastructure is approaching the end of its service life
- We need to update infrastructure to today's standards to ensure safety and reliability

Frequently Asked Questions
The aging infrastructure was built between 1962 and 1980. This power line needs to be rebuilt to keep power reliable for customers. Customer power needs are rising in Virginia. More generation (otherwise known as energy supply) is coming to meet those needs.
No. This project proposes to move the existing lines onto the new poles. Only the wires on the transmission line all the way from Basin to Chesterfield will be upgraded.
Dominion Energy plans to use a safety net for wires that cross over highways like I-95 and 288. This is a construction method that reduces traffic disruptions. The safety net is temporarily installed above the road, underneath wires. The wires can be safely removed and installed while traffic moves below.
The transmission structures are expected to be rebuilt near the existing line. Existing space will be used, but there are some areas that need additional right of way. If additional right of way is needed on your property, a Real Estate representative will contact you.

Legal
The Virginia State Corporation Commission (SCC) has regulatory authority over all energy providers in Virginia. Among other responsibilities, the SCC validates the need for a proposed line and approves the route and structures. In reviewing a proposed project, the SCC must consider whether potential impacts on scenic assets, historic districts and the environment have been reasonably minimized.
Once this project is submitted to the SCC, we will post our application and provide a link to the SCC's case docket where you will find documents related to the case, as well as information on how to submit comments.
