Hemingway-Kingstree Transmission Line Project

Santee Cooper plans upgrades to the transmission system to maintain and improve reliability, support future load growth, and provide resiliency. This project involves rebuilding an older 115 kilovolt(kV) transmission line and building a new 230 kV transmission line as double circuits with modern steel poles in existing right of way from Santee Cooper’s Hemingway Substation to Kingstree Switching Station in Williamsburg County, SC.  

Santee Cooper plans to construct this 22 mile transmission line over a 16-month period, starting in early 2027. There is one Santee Electric Cooperative Substation served from the existing 115 kV transmission line that is being rebuilt. There are currently no planned service disruptions. Santee Cooper intends to send letters to homeowners along the route before project construction starts.

Only a small amount of new ROW is proposed at this time, including small portions near the Hemingway and Kingstree stations, and near the Nesmith delivery point. A material storage site will also need to be obtained.

2024-2026: Studies, Planning, and Engineering

2027:  Receiving materials and beginning construction

2028: Finish building the new Hemingway to Kingstree line

2029: The project should be complete and in service by June 1, 2029, and should close by the end of the year after accounting, engineering, and lessons learned are settled.

We do not expect any significant traffic delays at this point.
