New Texas Gateway Pipeline to Boost Natural Gas Flow from East Texas to Gulf Coast Markets

Gulf South Pipeline Company LLC, a subsidiary of Boardwalk Pipelines, revealed on Thursday that it has initiated a binding open season for its Texas Gateway Project, a new natural gas pipeline designed to link East Texas with southwest Louisiana.

The binding open season commenced on October 31 and will continue until December 8, allowing companies to submit bids for capacity on the proposed pipeline. According to the company’s announcement, interested parties must enter into a minimum agreement lasting 20 years.

The Texas Gateway Project involves enhancements to current infrastructure alongside the development of a new 155-mile pipeline. The route will start in Carthage, Texas, and stretch southeast toward Beauregard Parish, Louisiana, approximately 15 miles north of Lake Charles.

Upcoming enhancements will feature changes to compressor stations located in Brazos, North Houston, Carthage, and Magasco, as well as the establishment of a new compressor station in Cleveland, Texas. The project is expected to commence operations on or around November 1, 2029, subject to regulatory approval.

“Texas Gateway showcases our dedication to providing cutting-edge infrastructure solutions for our clients,” stated Scott Hallam, president and CEO of Boardwalk Pipelines, in a company announcement. “This initiative aims to provide affordable access to international LNG markets, simultaneously supporting industrial and energy needs in the Gulf Coast area.”

The pipeline represents the most recent development in a succession of significant energy infrastructure initiatives revealed for southeast Texas. In early October, ARM Energy and Pacific Investment Management Co. announced the launch of their $2.3 billion Mustang Express Pipeline, which links Bay City to Port Arthur via the Katy region.

Additional initiatives include Kinder Morgan’s 216-mile Trident Intrastate Pipeline, which connects Katy to Port Arthur, and WhiteWater Midstream’s 450-mile Eiger Express, which links Katy to the Permian Basin. The projects highlight a significant increase in investment in Texas natural gas infrastructure, fueled by rising demand from liquefied natural gas (LNG) facilities and industrial consumers along the Gulf Coast.

The Texas Gateway Project establishes Boardwalk Pipelines as a primary contributor to enhancing the area's ability to supply natural gas to both domestic and international markets via Louisiana’s LNG export terminals.
