Southeast Supply Enhancement
Southeast Supply Enhancement
We make clean energy happen.
Project Overview & Resources
As energy demand in the Southeast and Mid-Atlantic accelerates, natural gas is supporting economic growth and helping meet the ever-increasing demand for clean, reliable and affordable power. Natural gas provides a reliable, efficient and low-emissions alternative to coal-fired electricity generation and is a natural partner with renewables.
The proposed expansion taps into established pipeline corridors to minimize environmental impact to property owners. It will be built and maintained using Williams’ industry-leading safety standards: That means 24/7 monitoring, rigorous maintenance, and the transparent communication that has made us a trusted neighbor.
Williams proposed Southeast Supply Enhancement project will provide additional energy reliability to support communities across the region. In addition to stimulating direct and indirect economic growth, SSE will add ~1.6 million dekatherms per day of natural gas transportation capacity — equivalent to what is needed to serve approximately 9.8 million homes.

Construction Activities
The project includes pipeline looping adjacent to existing Transco corridors and modifications to existing compressor and meter stations.
- Virginia Scope of Work: A total of 26.4 miles of pipeline looping adjacent to the existing Transco corridor and additional compressor units located in Pittsylvania County, Virginia. (Station 165)
- North Carolina Scope of Work: A total of 28.4 miles of pipeline looping adjacent to existing Transco corridors located in Rockingham, Guilford, Forsyth, and Davidson Counties and additional compressor units in Cleveland, Iredell, and Davidson Counties. (Stations 145, 150, 155)
- South Carolina Scope of Work: Compressor station reversal in Anderson County. (Station 135)
- Georgia Scope of Work: Compressor station reversal and regulator in Walton County (Station 120) and compressor station reversal in Henry County. (Station 125)
- Alabama Scope of Work: Compressor station reversal and modifications in Coosa County. (Station 105)
