ANR Gas Pipeline is an operational natural gas pipeline.[1]


The pipeline consists of two major legs. One runs from Texas, to Chicago, Illinois. The other runs from Louisiana to Chicago, Illinois. The route below was adapted from the EIA gas pipelines database.[2]

Project details

  • Owner: ANR Pipeline Company[3]
  • Parent company: TC Energy[4]
  • Capacity: 6000 Million cubic feet per day
  • Length: 2896.819 kilometers / 1800 miles
  • Status: Operating
  • Start year: 1949


ANR Pipeline delivers gas from Texas, the Oklahoma panhandle region, and Louisiana to the Midwest and Great Lakes region. It has two legs, one from Texas and the other from Louisiana, which meet near Chicago.


ANR was founded as the Michigan-Wisconsin Pipe Line Company on July 25, 1945. In 1947, the company received federal approval to build a $52 million, 1,800-mile-long pipeline from Texas to the Detroit-Ann Arbor area and to sections of Wisconsin, Missouri and Iowa. The Michigan-Wisconsin Pipeline began operations on November 1, 1949. The pipeline ran from Hansford County in the Texas Panhandle through Oklahoma, Kansas, Nebraska, Missouri and Iowa to Illinois, where it branches in two with one line to serve Michigan and the other Wisconsin.

The Michigan-Wisconsin Pipe Line Company's name was changed in 1984 to the ANR Pipeline Company, in order to identify the company more closely with its parent, American Natural Resources. In 1985, American Natural Resources was acquired by Coastal Corporation. El Paso Energy acquired Coastal Corporation in 2001. El Paso Energy sold ANR Pipeline to TC Energy in 2007.


Explosion of 1993

On November 23rd, 1993 there was an explosion on the pipeline in New Castle, Indiana.

Explosion of 2008

On March 11, 2008, an explosion occurred on the pipeline 15 miles (24 km) off the coast of Marsh Island, Louisiana, in the Gulf of Mexico, while the Motor Vessel Jillian Morrison was bleeding natural gas from a shut section of a pipeline into a tank on the vessel. Six crew members of the vessel were injured and one left missing.[5]

Rupture of 2014

On September 16, 2014, around 2am EDT, a rupture occurred on the pipeline in Benton Township, Berrien County, Michigan. About 520 people were evacuated.[6]

Expansion projects

Wisconsin Access Project

The project will upgrade compressor stations and meters to expand the ANR pipeline's capacity by 72 million cubic feet per day. The product is destined for contracted utilities in Illinois, Iowa, Kansas, and Wisconsin. As of October 2020, the project had been announced, but had not yet applied for approval with the Federal Energy Regulatory Commission (FERC).[7]

On 19 May 2022, FERC approved TC Energy's request to complete project modifications by summer 2022, to allow for a 1 November 2022 in-service date.[8]

  • Owner: ANR Pipeline Company[3]
  • Parent company: TC Energy
  • Capacity: 72 million cubic feet per day[7]
  • Length: 0 new km, capacity expansion only[7]
  • Cost: US$200 million[7]
  • Status: Proposed[7]
  • Start year: 2022[7]
  • Cost: US$5.5 million[8]

Grand Chenier XPress Project

The project will bring additional compression to the ANR system to increase deliverability to Cameron Parish, Louisiana. The project was partially completed in April 2021. It is expected to enter service in 2022.[7]

  • Owner: ANR Pipeline Company[3]
  • Parent company: TC Energy
  • Capacity: 420 million cubic feet per day (MMcf/d)[7]
  • Length: 0 new km, capacity expansion only[7]
  • Cost: US$200 million[7]
  • Status: Construction[7]
  • Start year: 2022[7]

Alberta Xpress Expansion Project

The expansion project, called the Alberta Xpress, will deliver Canadian gas into the Great Lakes Gas Transmission Pipeline, and then to the ANR gas pipeline system, ending with product delivery to LNG facilities on the U.S. Gulf Coast. The project only involves the ANR Gas Pipeline and is a capacity-expansion only, with no additional kilometers of pipeline added. It will effect natural gas transportation capacity in Michigan, Indiana, Ohio, Kentucky, Tennessee, Mississippi, Arkansas, Louisiana.[4]

The project was completed in January 2023.[4]

  • Owner: ANR Pipeline Company[3]
  • Parent company: TC Energy
  • Capacity: 165 MMcf/d[4]
  • Length: 0 new km, capacity expansion only[4]
  • Cost: US$81.1 million[4]
  • Status: Operating[4]
  • Start year: 2023[4]
    • Originally 2022

Elwood Power Plant Expansion Project

In August 2020, TC Energy announced that it will proceed with the Elwood Power/ANR Horsepower Replacement Project. The expansion project will replace, upgrade, and modernize certain facilities along a highly utilized section the ANR pipeline, resulting in up to 125,000 Dth/d of new firm transportation service to the existing Elmwood power plant. The expansion project's in-service target date is in the second half of 2022 and with an estimated cost of US$400 million.[9]

  • Owner: ANR Pipeline Company[3]
  • Parent company: TC Energy
  • Capacity: 125,000 dekatherms per day (Dth/d)[9] / 125 million cubic feet per day
  • Length: 0 new km, capacity expansion only[9]
  • Cost: US$400 million[9]
  • Status: Proposed[9]
  • Start year: 2022[9]

Skunk River Replacement Project

The replacement project is to abandon and replace 1,880 ft of mainline pipe in Henry County, Iowa, United States.

  • Operator: ANR Pipeline Company
  • Owner: ANR Pipeline Company
  • Parent company: TC Energy
  • Capacity: 0 MMcf/d new capacity[4]
  • Length: 0.356 mi[4]
