Williams Adds 514 MMcf/d as Two Transco Expansions Enter Service in Southeast, Gulf Coast
(P&GJ) — Williams has placed two Transco pipeline expansion projects into service, adding 514 million cubic feet per day (MMcf/d) of natural gas capacity to meet growing demand in the Southeast and Gulf Coast regions.
The projects include the Southeast Energy Connector in Alabama and the Texas to Louisiana Energy Pathway, both fully contracted expansions of the Transco system. The company said the new capacity supports increased power generation needs, manufacturing growth, and rising LNG export demand.

“I congratulate our team for the efficient completion of these projects, demonstrating our ability to execute large-scale expansions in a safe and environmentally responsible manner,” said Alan Armstrong, president and CEO of Williams. “Demand for affordable, reliable and clean natural gas continues to grow across U.S. markets, driven by increasing electric power generation, reshoring of energy-intensive manufacturing, data center load growth and LNG exports."
The Texas to Louisiana Energy Pathway adds 364 MMcf/d to Transco’s capacity in Texas and Louisiana, while the Southeast Energy Connector delivers 150 MMcf/d to support the region’s coal-to-gas power conversion efforts.
The expansions follow a record-setting winter for Transco, which logged 19 of its 20 highest-volume transmission days, driven by cold weather, electricity demand, and LNG exports.
With these additions, the Transco pipeline system—spanning more than 10,000 miles from South Texas to New York City—now has a system-design capacity exceeding 20 billion cubic feet per day. Williams also continues to expand its Northwest Pipeline and MountainWest systems to support demand in the West and Pacific Northwest.
