Williams Expands Transco Pipeline with Two New Projects to Meet Southeast Energy Demand

Williams announced the successful launch of two new Transco pipeline expansions: the Southeast Energy Connector in Alabama and the Texas to Louisiana Energy Pathway. These projects aim to address growing demand for natural gas in the Southeast U.S., driven by increased power generation, manufacturing, data centers, and LNG exports.

The Southeast Energy Connector adds 150 million cubic feet per day (MMcf/d) to support Alabama’s transition from coal to natural gas for electricity generation. The Texas to Louisiana Energy Pathway expands capacity by 364 MMcf/d to improve infrastructure reliability and support LNG activity along the Gulf Coast.

Williams emphasized its commitment to minimizing environmental and community impacts while delivering efficient, large-scale infrastructure. These projects increase Transco’s system capacity to over 20 billion cubic feet per day (Bcf/d), reinforcing its status as the largest-volume natural gas pipeline in the U.S.

Williams currently operates over 33,000 miles of pipeline and is advancing 12 additional transmission projects to meet surging energy demands nationwide while supporting the clean energy transition.
