Transco Project Would Serve Gulf Coast LNG Terminals

Williams' Transcontinental Gas Pipe Line Co. LLC (Transco) has filed at FERC for its Gulf Connector Project, a two-phase expansion of the pipeline's system in Texas and Louisiana. Capacity would be used to deliver natural gas to two Gulf Coast liquefied natural gas (LNG) terminals.

Gulf Connector would enable Transco to provide 475,000 Dth/d of incremental firm transportation service from Transco's Station 65 Zone 3 Pool in St. Helena Parish, LA, southward along its mainline to new delivery points in Zones 1 and 2. The first phase would provide 75,000 Dth/d by Sept. 1, 2018; Phase 2 would provide an additional 400,000 Dth/d by Jan. 1, 2019. Transco asked for Federal Energy Regulatory Commission authorization by July 1, 2017 to meet the planned in-service dates [CP16-494].

Transco would construct three compressor stations, add an interconnection with Cheniere Corpus Christi Pipeline LP's pipeline, and make piping and valve modifications at two existing Transco compressor stations to allow for bi-directional gas flow. No expansion of the Transco's pipeline is required.

The project would allow Transco to carry gas to a proposed interconnection with Gulf South Pipeline Co. LP's Coastal Bend Header (see Daily GPI, Jan. 29) in Wharton County, TX, and a proposed interconnection with Cheniere Pipeline in San Patricio County, TX (see Daily GPI, Dec. 31, 2014). The project would not affect Transco's ability to provide northbound transportation service on its mainline, the pipeline told FERC.

Transco has struck binding precedent agreements with two customers: Corpus Christi Liquefaction LLC and Osaka Gas Trading & Export LLC for 100% of the incremental firm service to be provided. Via Transco's interconnection with Coastal Bend Header, the project would enable gas delivery to Freeport LNG Development LP's export terminal in Brazoria County, TX. The project also would enable gas delivery to Cheniere Energy's Corpus Christi, TX, LNG terminal.
