Project Details

  • Operator: TC Energy[1]
  • Current capacity: 3 Billion cubic feet per day[2]
  • Proposed capacity:
  • Length: 12,000 miles / 19,312 km[1]
  • Status: Operating[1]
  • Start Year: 1996[1]


Columbia Gas Transmission is owned and operated by TC Energy.[3] It was acquired by TC Energy as part of its $13 billion purchase of the Columbia Pipeline group in 2016.[4] The acquisition came after TC Energy's 2015 failure to win approval for its proposed Keystone XL Pipeline, and TC Energy's CEO Russ Girling stressed the company's desire to increase its capacity to carry gas from the lucrative Marcellus and Utica Shale regions.[5]

Expansion Projects

East Lateral Xpress Project

The expansion will provide additional transportation services on Columbia Gulf’s East Lateral from Columbia Gulf’s Onshore Pool (CGT-Rayne) and the Venice Meter Station to a new delivery point with the Gator Express Pipeline in Plaquemines Parish, Louisiana.[6]

As of September 2020, developers had already applied for project approval with the Federal Energy Regulatory Commission (FERC).[6]

East Lateral Xpress Project Details

  • Operator: Columbia Gas Transmission[6]
  • Owner: TC Energy[1]
  • Capacity: 183 million cubic feet per day (MMcf/d)[6]
  • Length: 8 miles / 12.9 kilometers[6]
  • Diameter: 30-inches[6]
  • Cost: US$364 million[6]
  • Status: Proposed[6]
  • Start Year: 2023[6]

Marysville Connector Pipeline

The expansion will supply additional gas to the Marysville, Ohio area by running a line from Dublin, Ohio to Marysville, Ohio. Developers have received project approval from the Federal Energy Regulatory Commission (FERC).[6]

Marysville Connector Pipeline Project Details

  • Operator: Columbia Gas Transmission[6]
  • Owner: TC Energy[1]
  • Capacity:
  • Length: 2.18 miles / 3.5 kilometers[6]
  • Diameter: 12-inches[6]
  • Cost: US$28 million[6]
  • Status: Proposed[6]
  • Start Year: 2023[6]

Virginia Expansion Project Background

The expansion project is in Virginia. It is a capacity expansion only, with no additional kilometers added.[7]

Expansion Project Details

  • Operator: Columbia Gas Transmission[7]
  • Owner: TC Energy[1]
  • Capacity: 45 million cubic feet per day[7]
  • Length: 0 new kilometers[7]
  • Status: Operating[7]
  • Start Year: 2018[7]

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. It does not include adding any additional miles of pipeline.[7]

In August 2020 it was reported that Columbia Gulf Transmission was pressing the U.S. Federal Energy Regulator Commission (FERC) to fast-track authorization of the Louisiana XPress Project which already received a favorable 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.[8]

According to the U.S. Energy Information Administration, as of April 2021 the project was under-construction.[9]
