Columbia Gas Transmission is an operating system of natural gas pipelines.[1]
Location
The pipeline runs from points in the Midwest and Southeast to New York.[1]
Project Details
- Operator: Columbia Gas Transmission
- Owner: 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]
Background
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]
In July 2023, a section of the pipeline in western Virginia exploded, prompting a temporary localized shutdown.[6]
In July 2023, TC Energy announced that it will divest a 40% interest in its Columbia Gas Transmission and Columbia Gulf Transmission pipelines for US$5.2 billion to Global Infrastructure Partners (GIP). The transaction is expected to close in fourth quarter 2023.[7][8]
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 Gas Pipeline in Plaquemines Parish, Louisiana.[9]
As of September 2020, developers had already applied for project approval with the Federal Energy Regulatory Commission (FERC).[9]
- Operator: Columbia Gas Transmission[9]
- Owner: TC Energy[1]
- Capacity: 183 million cubic feet per day (MMcf/d)[9]
- Length: 8 miles / 12.9 kilometers[9]
- Diameter: 30-inches[9]
- Cost: US$364 million[9]
- Status: Proposed[9]
- Start Year: 2023[9]
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).[9]
- Operator: Columbia Gas Transmission[9]
- Owner: TC Energy[1]
- Capacity:
- Length: 2.18 miles / 3.5 kilometers[9]
- Diameter: 12 in[9]
- Cost: US$28 million[9]
- Status: Proposed[9]
- Start Year: 2023[9]
Virginia Expansion Project Background
The expansion project is in Virginia. It is a capacity expansion only, with no additional kilometers added.[10]
- Operator: Columbia Gas Transmission[10]
- Owner: TC Energy[1]
- Capacity: 45 million cubic feet per day[10]
- Length: 0 new kilometers[10]
- Status: Operating[10]
- Start Year: 2018[10]
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.[10]
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.[11]
According to the U.S. Energy Information Administration, as of April 2021 the project was under-construction.[12] As of January 2022, part of the project was complete[12], but the TC Energy website still identified the project as in development.[13]
