TULSA — Williams Partners LP is planning to expand its Transco pipeline system to ship more than 1 million dekatherms of natural gas a day to an export facility being built in Louisiana.
Subsidiary Transcontinental Gas Pipe Line Co. LLC will spend about $300 million on the Gulf Trace expansion project, which is proceeding thanks to the anchor shipper commitment from Sabine Pass Liquefaction LC.
Sabine Pass is a liquefied natural gas export project being developed by Houston-based Cheniere Energy Partners LP. Construction of the nation’s first large-scale LNG export facility could be completed as soon as the last quarter of 2015.
Williams Partners hopes to have the Transco expansion project in service by early 2017, pending regulatory approval.
“Gulf Trace is a pivotal project at an extremely important time for Transco and the U.S. natural gas industry as a whole,” said Rory Miller, senior vice president of Williams Partners’ Atlantic-Gulf operating area.
The Gulf Trace project includes pipeline reversal, a new eight-mile lateral and two new compressor stations to provide firm transportation service to Sabine Pass. The expansion will be able to deliver as much as 1.2 million dekatherms a day.
