ANR Pipeline



The ANR Pipeline was founded in 1945 as the Michigan-Wisconsin Pipe Line. Built as part of America’s post-war expansion, the pipeline transports natural gas from Texas, Oklahoma, and Louisiana to cities and towns in Wisconsin, Michigan, Illinois and Ohio.

The two major legs of ANR Pipeline converge near Chicago. ANR also provides access to TC Energy’s extensive natural gas storage operations in Michigan.

As a result of a major capital program, natural gas can now flow in either direction on ANR.

Thanks to our commitment to pipeline safety and security, ANR is poised to support the Midwest for many years to come.
