Bison Gas Pipeline is a natural gas pipeline that runs from Wyoming to North Dakota.[1]
Location
The pipeline runs from Gillette, Wyoming, to Glen Ullin, North Dakota.
Project Details
- Operator: Bison Pipeline LLC[2]
- Owner: TC Energy[3]
- Current capacity: 477 million cubic feet per day[2]
- Length: 302 miles / 486 km[2]
- Diameter: 30-inches[2]
- Cost: US$610 million[2]
- Status: Operating[2]
- Start Year: 2011[2]
Background
TC Energy's Bison Gas Pipeline was built by Michels Pipeline Construction and Price Gregory International, and became operational on Jan. 14, 2011.[4] TC Energy president Russ Girling explained the need for the pipeline this way: “The Rockies was one of the last major North American producing basins that we weren’t connected to."[4]
TC Energy originally bought the pipeline project in 2008 from Northern Border Pipeline Co. as a way of adding new shippers for its planned Pathfinder natural gas pipeline from the U.S. Rockies region.[5]
Expansion Background
The pipeline originally had 407 million cubic feet per day (MMcf/d) of operational capacity, but its design capacity with compression was approximately 477 MMcf/d with potential expandability to approximately 1 billion cubic feet per day.[1] Eventually, the operational capacity was expanded to 477 million cubic feet per day (MMcf/d).[2]
Accidents
The pipeline exploded in a remote area near Gillette, Wyoming, on July 20, 2011, blowing out a 36-foot section of the pipeline and shaking buildings more than a half-a-mile away.[6] In October 2012, the Canadian Broadcast Company (CBC) published internal TC Energy documents that showed employees were concerned about potential safety issues related to welding and inspection. "We are in trouble on the Bison project," the pipeline's construction manager wrote in Sept. 18, 2010.[7] TC Energy previously claimed that it would be "20 or 30 years" before the pipeline needed any repairs.[8]
Ranchers and others who lived along the route of the pipeline expressed concerns about shoddy construction after soil on top of the pipeline sank in the spring of 2011, as shown in this photograph:
Decline In Demand
The amount of gas flowing through the pipe dropped precipitously after its first year in operation, then dropped to nothing in 2015, according to a June 2016 report by BTU Analytics: "When the pipeline first opened, shippers ramped up volumes to nearly fill the pipeline, but changing natural gas pricing spreads and declines in Powder River volumes left the pipeline empty until the polar vortex of 2013. As storage volumes in the Canadian and Midwest markets have replenished, Bison flows have since returned to zero."[9]
