TC Energy Corp. subsidiary Columbia Gulf Transmission LLC has filed an abbreviated application at FERC to build, own and operate the Louisiana XPress (LAXP) natural gas pipeline project, which would provide open access firm transportation service through the expansion of existing capacity on Columbia's current pipeline system.

The project would include construction of three new greenfield compressor stations, modifications at one existing compressor station, and related facilities to create 493 Mmcf/d of incremental mainline capacity on the Columbia system.

"The incremental capacity created by the project, in conjunction with the utilization of existing capacity, will allow for open access firm transportation service on approximately 850 MMcf/d of capacity on a north-to-south path from Columbia Gulf's Mainline Pool to a primary point of delivery with Kinder Morgan Louisiana Pipeline LLC in Evangeline Parish, Louisiana," Columbia said in its application.

Columbia held a binding open season last year, and said in the application that it has executed a binding precedent agreement with a shipper to provide 800 MMcf/d of long term firm transportation service, providing the required market support for the project. That capacity will provide transportation service to the Sabine Pass Liquefaction export terminal in Cameron Parish, LA, where Cheniere Energy is progressing on plans for Train 6, Columbia said.

Columbia is seeking approval by July 1, 2020, from the Federal Energy Regulatory Commission in order to build the project and commence service by Feb. 1, 2022.

The estimated cost of the Louisiana XPress project is $472 million.
