NGL and offgas fractionation is provided through interests in one straddle plant at Cochrane, as well as an integrated offgas business that includes the Redwater Olefinic Fractionator, Pioneer I and Pioneer II processing facilities located near Fort McMurray, Alberta, and the Boreal pipeline system that connects these facilities.
The facilities infrastructure segment generates adjusted EBITDA that is supported by fee-based and cost-of-service arrangements and sells commodity-based products to the marketing segment for fixed service fees.
The Cochrane straddle plant extracts and fractionates NGL into ethane and propane-plus and by production capacity, is one of the largest facility of its type in Canada. The plant has processing design capacity of 2.5 bcf/d of natural gas to recover approximately 100,000 b/d of NGL, of which 65,000 b/d are ethane and 35,000 b/d are propane-plus and processes a significant portion of available gas on the western leg of the TC Energy Alberta System.
Pioneer I and Pioneer II are two offgas plants located near Fort McMurray, Alberta and have the capacity to recover approximately 40,000 b/d of an ethane-plus mixture from upgrader offgas, a by-product of bitumen upgrading operations, helping to reduce GHG emissions. Once extracted, the liquid mix is shipped via pipeline to Inter Pipeline’s Redwater Olefinic Fractionator where it is fractionated into marketable products.
The Redwater Olefinic Fractionator is an ethane-plus fractionation plant near Redwater, Alberta. Ethane-plus produced from offgas processing is fractionated into an ethane-ethylene mixture as well as propane, polymer grade propylene, normal butane, alky feed and olefinic condensate. Once fractionated, the segregated products are sold and then transported to end-user markets by pipeline, truck or rail.
The Boreal pipeline system connects these facilities from Northern Alberta to the Alberta Industrial Heartland Alberta and has a current throughput capacity of 43,000 b/d of ethane-plus mixture.

This project highlights our commitment to sustainable operations
Inter Pipeline is pleased to be invited to work with Alberta Energy to further evaluate development of an environmentally safe carbon storage hub. The location outlined in our application for this tenure is north of Cochrane where we currently operate the Cochrane natural gas extraction plant. This project highlights Inter Pipeline’s commitment to sustainable operations through reducing emissions both at its own assets and at those of others in the energy industry. We look forward to working closely with the Government of Alberta to clarify and formalize next steps.
Inter Pipeline is pleased to be partnering with Entropy Inc. on this initiative. Entropy is an organization that specializes in carbon capture and storage technology. Brookfield Renewable announced a substantial investment in Entropy earlier this year through its Global Transition Fund.
Brookfield Infrastructure Partners acquired Inter Pipeline in 2021.
Inter Pipeline prioritizes the safety and protection of the environment for our employees, customers, shareholders and the communities in which we operate.
