Columbia Gulf Transmission is an operating natural gas pipeline.[1]


The pipeline runs from the Gulf of Mexico to connecting pipelines in Louisiana, Tennessee, Kentucky, and West Virginia.[2]

Project Details

  • Operator: Columbia Gulf Transmission LLC
  • Owner: Transcanada
  • Current capacity: 1.7 Billion cubic feet per day
  • Proposed capacity:
  • Length: 3,341 miles / 5,376 km
  • Status: Operating
  • Start Year: 1996


Columbia Gulf Transmission gathers gas in the Gulf of Mexico and brings it to Columbia Gas Transmission. It is owned by Transcanada.[3] Its FERC code is 70.[4]

Louisiana XPress Expansion Project

Columbia Gulf Transmission applied for an expansion in 2019 called the Louisiana XPress Project. The expansion would cost US$472 million and add 493 million cubic feet per day (MMcf/d) of natural gas transportation capacity. The expansion would effect Kentucky, Tennessee, Mississippi, and Louisiana.[5]

In August 2020 it was reported that Columbia Gulf Transmission was pressing the U.S. Federal Energy Regulator Commission (FERC) to fast-track authorisation of the Louisiana XPress Project which already received a favourable environmental assessment from FERC in February 2020. The promoters of the project, which will mainly provide additional supply into Cheniere Energy’s operating [[Sabine Pass LNG Terminal] in Louisiana's Cameron Parish, are pushing to begin construction of the project in September 2020 to avoid the rainy season in order to meet their intended February 2022 in-service target date.[6]
