Oct 30 (Reuters) - Gulf South Pipeline Company LLC, a

subsidiary of Boardwalk Pipelines LP, announced on Thursday a

binding open season for the Texas Gateway Project, inviting firm

commitments to reserve capacity at its planned new network.

The Texas Gateway Project aims to connect Gulf South's

existing network with new pipeline infrastructure, and will

gather natural gas from the Katy and Carthage hubs in Texas,

Boardwalk said in a press release.

The gas will be delivered to Southwest Louisiana near

Gillis, where demand is rising, according to the release.

It said the project will increase liquidity, supply security

and flow assurance for LNG exporters, electric utilities,

industrials and natural gas producers.

"This project would enable low-cost natural gas supply

access to global LNG markets while also fueling industrial and

power demand in the Gulf Coast region," said Scott Hallam,

president and CEO of Boardwalk Pipelines.

Gulf South has secured a deal with a long-term user under

terms that will allow it to advance the project, and will use

this open season to determine additional interest, according to

the release.

The project will add at least 1.45 billion cubic feet per

day (1.450 million Dth/d) of capacity to Southwest Louisiana, it

added.

It includes a new 155-mile pipeline and upgrades to the

existing Index 129 pipeline in southeast Texas. The new line

will start at the Carthage Header and extend to Beauregard

Parish, Louisiana.

It will include new compression and metering facilities, the

release said, adding that the target start date is November 1,

2029.
