Varnville-Robertville 69kV Rebuild

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 69 kV transmission line and building a new 115 kV transmission with modern steel poles in existing right of way from Santee Cooper’s Varnville Station to the Nixville tap.

Santee Cooper plans to construct this 6-mile transmission line over a 4-month period, starting around March 2026. There are currently no planned service disruptions. Santee Cooper intends to send letters to homeowners along the route before project construction starts and have previously sent letters to landowners along the route informing them of project activities.

No new right of way will be needed from landowners.

2024-2025: Studies, Planning, and Engineering

2025: Receiving materials and final permitting

2026: Construction likely to start in March

2026: Projected construction end date in July. Project should wrap up by Dec. 32, 2026, after accounting, engineering, and lessons learned are settled.

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