Williams Transcontinental Gas Pipe Line Co. LLC (Transco) has applied at FERC for an expansion of its system in Louisiana to serve the liquefied natural gas (LNG) terminal of Cheniere Energy’s Sabine Pass Liquefaction LLC.

Transco would expand its system to provide 1.2 million Dth/d of firm, year-round service from its Station 65 Zone 3 Pool in St. Helena Parish, LA, southward along its mainline and Southwest Louisiana Lateral and through a new seven-mile lateral to the Sabine Pass terminal in Cameron Parish, LA, the pipeline told the Federal Energy Regulatory Commission [CP15-29].

Despite a recent open season, no other parties besides Sabine Pass signed up for capacity on the project, which is called Gulf Trace (see Daily GPI, April 17).

“The precedent agreement between Sabine Pass and Transco requires the parties to execute a firm transportation service agreement under Rate Schedule FT, with a primary term of 20 years, within 30 days of Transco’s receipt and acceptance of the authorizations requested herein,” the pipeline told FERC. “Sabine Pass will be responsible for contracting directly with suppliers of natural gas and arranging for the deliveries of gas supplies to be transported from Transco’s Station 65, Zone 3 Pool to the…terminal.”

Transco asked the Commission to approve the project by Sept. 1 to allow for an in-service date of Jan. 1, 2017. The project is intended to serve trains three and four at Sabine Pass (see Daily GPI, Feb. 20).
