ANR Pipeline


Founded as the Michigan-Wisconsin Pipe Line Company in 1945, the ANR Pipeline Company became part of TC Energy in 2007 and operates one of the largest interstate natural gas pipeline systems in the U.S. 

With access to major producing basins in North America, the ANR system transports natural gas from Texas, Oklahoma and Louisiana to cities and towns in Wisconsin, Michigan, Illinois and Ohio, with two major legs of the system converging near Chicago. ANR also provides access to TC Energy’s extensive natural gas storage operations in Michigan.

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