A Line Rebuild Project in Charleston County, SC
At Dominion Energy, we remain committed to providing our customers with safe and reliable energy. This focus led to the creation of the Queensboro-Church Creek project. We will rebuild the 115-kilovolt (kV) electric transmission line from Queensboro to Church Creek in Charleston, South Carolina and interconnect a “tie line” with Santee Cooper on Johns Island. This project will work with Santee Cooper to increase reliability and resiliency for the growing Johns Island area and to rebuild Dominion Energy South Carolina’s aging infrastructure in the region.
To better serve the growing Johns Island area, DESC will construct a new transmission line along its existing right of way between the Queensboro Substation on James Island and the Church Creek Substation on Johns Island. This line will parallel the existing line follow its right of way.
This entire project is approximately 9.5 miles in length and will be done exclusively on existing right of way along a transmission corridor. All new transmission structures will be rebuilt on galvanized steel monopoles designed to meet all modern National Electric Safety Code requirements.
Letters will be sent to impacted property owners along the route as DESC gets closer to construction. Property owners can expect to see right of way flagging along the corridor. Because only one side of the existing right of way has been utilized up to this point, there will be some tree trimming necessary to reclaim the full extent of the right of way.
The project begins on James Island at the Queensboro Substation on George Griffith Blvd. From there it passes in the front of the Meridian Place neighborhood, through the James Island County Park, and across the Stono River onto Johns Island. On Johns Island, the line turns north and crosses Maybank Highway and Rushland Landing Rd. before crossing the Stono River into Charleston. The line will cross Highway 17 and stop near Glenn McConnell Parkway.
The engineering design and environmental permitting began in the summer of 2020 continued through 2021. Line construction is expected to start in the 3rd quarter of 2022 and will continue through the end of 2023.
The major road crossings for this project are Maybank Highway and Hwy 17. Construction work will be sequenced to cause minimal interruptions to traffic patterns. Additionally, the line crosses the Stono River twice. Residents can expect to see barges and other construction equipment in the Stono River while construction is happening. Residents may see brief traffic delays.
