Bison Pipeline

Natural Gas Icon


Bison Pipeline stretches 302 miles (486 km) across Wyoming and Montana to Midwestern North Dakota where it connects with another interstate natural gas pipeline. Thanks to the hard work of local employees and contractors, the pipeline safely delivers natural gas to families who depend on it for heating homes, cooking meals and more.

TC Energy operates Bison Pipeline and effectively owns 26.8 percent of the pipeline through its interest in TC PipeLines, LP.

Bison Pipeline delivers cleaner burning natural gas for heating, cooking, and more to the American Midwest. Opened in 2011, the final route of the line was approved following consultation with local Indigenous and non-Indigenous communities. The pipeline currently offers 407 million cubic feet per day of operational capacity.

Good question. Since we live in the same communities you do, we share your concerns. We spend between $200 and $300 million per year inspecting, repairing and upgrading our systems to keep your drinking water safe. Since 2011, the line has operated with 100 percent safety.
