TransCanada’s 303-mile Bison pipeline has started moving natural gas from northeastern Wyoming to Midwest markets.

The 30-inch-diameter pipeline is the company’s first to access natural gas produced in the US Rocky Mountain region.

The pipeline begins in northeastern Wyoming, going through Montana and North Dakota before connecting with Northern Border Pipeline in North Dakota.

Natural gas transported on Bison will reach Midwest markets through Northern Border, a pipeline partially owned by the firm indirectly through its interest in TC PipeLines.

The interstate pipeline has an initial capacity of 407 million ft3 a day, and could be expanded to 1 billion ft3 a day with extra compression.

TransCanada president and CEO Russ Girling said that Bison gives new options to producers in the Powder River Basin and to Midwest consumers.

"Connecting to Northern Border provides a lower-cost overall competitive solution for Bison’s customers, and it adds value to an existing asset by strengthening its contract profile and diversifying its gas supply mix," Girling said.

With the Bison pipeline, TransCanada has placed six major projects into service in the last ten months.
