Williams completes key Transco upgrade, boosting gas supply in North Carolina and Virginia
(UI) — Williams has announced that its Southside Reliability Enhancement project is now fully operational, increasing natural gas capacity in North Carolina and Virginia. The expansion adds 423,400 dekatherms per day (Dth/d) of pipeline capacity, sufficient to meet the energy needs of more than 2 million homes.
The project, completed on schedule, comes as demand for natural gas surges during the heating season. Transco, the nation’s largest-volume natural gas pipeline system operated by Williams, set an all-time daily peak of 17.77 million Dths on Dec. 22, surpassing its previous record earlier in the month. In New York alone, Transco delivered over 2.2 million Dths on the same day, marking its highest delivery in recent years.
“The on-time completion of this latest project underscores our team’s ability to execute large-scale expansions in a careful, efficient, safe and environmentally responsible manner,” said Alan Armstrong, president and CEO of Williams. “Our entire team continues to execute on a full portfolio of transmission growth projects to meet accelerating natural gas demand in the United States.”
The Southside Reliability Enhancement project includes a new all-electric compressor station in Mecklenburg County, Virginia, additional compression at Station 166 in Pittsylvania County, and upgrades to meter stations in several North Carolina counties. By optimizing the existing Transco corridor, the project minimized land use and environmental impact while expanding capacity to meet growing energy needs in North and South Carolina.
Williams emphasized the critical role of natural gas infrastructure in ensuring energy security during periods of peak demand. “The recent frigid conditions across the Northeast are an important reminder of the vital role transmission pipelines play in delivering the natural gas necessary to keep millions of Americans safe and secure,” Armstrong added.
With this expansion, Transco’s system-design capacity has increased to 19.9 million Dths per day, further solidifying its role in transporting approximately 20% of the natural gas produced in the U.S.
