Boardwalk launches Texas Gateway open season aiming to deliver natural gas to Gulf Coast
Gulf South Pipeline Co. LLC, a subsidiary of Boardwalk Pipelines LP, Houston, will launch a binding open season for the Texas Gateway project aimed at providing a link between natural gas supplies in Louisiana and Texas and demand along the Gulf Coast.
The Texas Gateway project is expected to include both a new pipeline and upgrades to Gulf South’s existing Index 129 pipeline in southeast Texas. The new pipeline is about 155 miles of greenfield pipeline originating at Gulf South’s existing Carthage Header and extending south to Beauregard Parish, La., with new compression and metering facilities, the company said in a release Oct. 30.
Index 129 upgrades would modify existing Gulf South compressor stations and add a new station near Cleveland, Tex., the company continued.
The targeted in-service date is Nov. 1, 2029.
The company said the project “is designed to combine Gulf South's existing footprint with new greenfield infrastructure to aggregate natural gas supplies from the Katy and Carthage, Tex., hubs for ultimate delivery to Southwest Louisiana near Gillis, and increase liquidity, supply security, and flow assurance for LNG exporters, electric utilities, industrials and natural gas producers.”
Gulf South said it has executed a precedent agreement with a foundation shipper under terms sufficient to advance the project and will use the open season to determine additional interest.
The Texas Gateway project is expected to provide a minimum of 1,450,000 Dth/d of capacity to Southwest Louisiana. The final design and scope of facilities will be determined at the end of the open season, the company said.
The bidding period begins Oct. 31, 2025 and ends Dec. 8, 2025.
