South Bow Secures 20-Year Commitments for Prairie Connector Crude Pipeline
According to RBN Energy, South Bow Corp. announced on May 29 a “successful outcome” of the open season it held in March, securing 20-year binding commitments for crude oil transportation from Hardisty, AB to US delivery points including Cushing, OK and the Gulf Coast.
Market Impact
The open season offered approximately 450 Mb/d of capacity, representing about 82% of the pipeline’s initial proposed capacity of 550 Mb/d. While South Bow did not disclose the exact volume committed, Reuters reported in early May that at least 400 Mb/d in commitments had been received.
South Bow is advancing Prairie Connector, the Canadian portion of the pipeline project formerly known as Keystone XL, toward a final investment decision (FID) targeted for mid-2027. The project involves construction of approximately 380 km (236 miles) of 36-inch pipeline and will leverage approximately 150 km (93 miles) of previously installed and preserved pipeline along with two pump stations. Prairie Connector would connect with Bridger Pipeline LLC’s proposed Bridger Expansion project at the Alberta-Montana border, with Bridger delivering crude to the Guernsey, WY hub.
One key uncertainty remains. Reuters reported that South Bow CEO Bevin Wirzba, speaking at a Calgary conference on May 28, said the company will not proceed until the US Presidential Permit for the border crossing segment, signed by President Trump on April 30, proves “durable.” That concern reflects the history of Keystone XL, whose Presidential Permit was rescinded by President Biden on his first day in office in January 2021. The Montana Department of Environmental Quality and the US Bureau of Land Management expect to issue a Record of Decision on Bridger’s project by spring 2027.
What It Means for Subcontractors
- Pipeline construction opportunity: If FID is reached in mid-2027, construction of 236 miles of 36-inch mainline pipe will generate significant demand for welding crews, right-of-way contractors, equipment operators, and civil construction subcontractors across Alberta and Montana.
- Integrity and reactivation work is near-term: The project plans to reuse approximately 93 miles of previously installed and preserved pipeline and two pump stations, meaning pipeline integrity assessment, inspection, and recommissioning contractors could see work before full construction mobilization.
- Watch the regulatory calendar: The spring 2027 Record of Decision from Montana DEQ and BLM is a hard gating milestone. Subcontractors should track that decision closely, as it will signal whether the US side of the project is cleared to proceed alongside any FID announcement.
- Permit durability risk is real: South Bow has explicitly conditioned its FID on the Presidential Permit holding. Subcontractors considering early resource commitments should factor in that political risk before locking up equipment or personnel for this project.
- Guernsey takeaway is still open: South Bow has confirmed no project has been announced yet to move crude beyond Guernsey, WY. That gap may represent additional pipeline or terminal work for midstream contractors further down the line.
