Overview

Dominion Energy South Carolina (DESC) is beginning a series of new electric transmission projects in Jasper County to continue to meet the growing demand for safe and reliable energy in the area. The projects will require the acquisition of new right-of-way easements, the installation of two new 230 kV lines and a new electric substation. Once installed, this system enhancement will provide necessary upgrades in the area to facilitate increased electrical reliability and improved flow of power across the electrical grid.

Because this project requires the acquisition of new rights of way, DESC will be conducting a siting study to determine the optimal route for the lines. During the siting study, Dominion Energy will host two public workshops to gather input and feedback from the public to factor into the study. Additionally, a third-party consulting firm will be contracted to analyze different route options and various environmental and visual impacts, which will factor into the route selected. After the siting study is complete, DESC will choose the optimal route and notify the impacted property owners to begin the right-of-way acquisition process.

The siting study began in the third quarter of 2021. The first public workshop will be held on December 2, 2021 and the second public workshop will be held in the spring of 2022. The final route should be determined by June of 2022 at which point the right-of-way acquisition process will begin.

Once all right-of-way is acquired, DESC will begin the engineering design, environmental permitting, and material procurement. Tree clearing and construction of the transmission lines and substation is expected begin in the 3rd quarter of 2023.

DESC will be installing two new 230 kV lines in Jasper County. The first 230 kV line will begin at Dominion Energy’s Jasper Generating Plant and will conclude at Dominion’s existing Okatie Substation. The second 230 kV line will begin at the Okatie Substation and will conclude at the new Riverport Substation.

While most of the line is away from heavily traveled areas, there may be traffic control set up at road crossings occasionally as Dominion Energy and its contractors ensure the work is completed safely and effectively. The three major road crossings associated with this project are Highway 17, Main St in Hardeeville, and Independence Boulevard (Highway 141). Dominion Energy expects there to be no interruptions to existing customer’s power.
