Williams Partners said Transcontinental Gas Pipe Line Company filed an application with the Federal Energy Regulatory Commission (FERC) to construct a 475,000 dekatherm per day (Dth/d) expansion in Texas and Louisiana that would connect natural gas supplies with global LNG markets.
Constructed in two phases, the Gulf Connector Project is designed to deliver 75,000 Dth/d to Freeport LNG Development’s liquefaction project by the second half of 2018, and 400,000 Dth/d to Cheniere Energy’s Corpus Christi liquefaction terminal in 2019. Construction of the first phase of the project is expected to begin in the third quarter of 2017, with service beginning in the second half of 2018.
Both of the liquefaction facilities are currently under construction. The Freeport LNG export terminal will have three liquefaction trains with expected aggregate export capacity of 15.3 mtpa. It is expected to begin operations in phases between September 2018 and August 2019.
Cheniere Energy’s Corpus Christi liquefaction terminal is proposed to have up to five liquefaction trains, two of which are under construction, with expected aggregate nominal production capacity of up to 22.5 mtpa of LNG. Trains one and two at the Corpus Christi liquefaction terminal are expected to reach “substantial completion” in 2019.
The Gulf Connector Project involves adding compression and making the natural gas flow bi-directional on a portion of the Transco system between Louisiana and South Texas. The project has been designed to provide incremental firm transportation from Transco’s Station 65 in St. Helena Parish, LA to mainline interconnects with proposed header pipelines in Wharton and San Patricio counties in Texas.
As previously announced, Williams Partners is also building the Gulf Trace Project to serve Cheniere Energy’s Sabine Pass Liquefaction project in Cameron Parish, LA, the first large-scale LNG export facility in operation in the continental United States. The Gulf Trace Project is expected to be completed in the first quarter of 2017.
