What Aux Sable does
Aux Sable is a privately held North American midstream infrastructure company that extracts and fractionates natural gas liquids (NGLs) from liquids-rich natural gas. It is a wholly owned subsidiary of Pembina Pipeline Corporation and operates through three entities: Aux Sable Liquid Products (ASLP), which owns and operates the Channahon NGL Extraction & Fractionation Facility in Illinois — described as one of the largest such facilities in North America, capable of processing 2,100 MMcfd of natural gas and producing approximately 131,500 bpd of specification NGL products; Aux Sable Midstream (ASM), which operates the 80 mmcfd Palermo Conditioning Plant in North Dakota and the Prairie Rose Pipeline that feeds conditioned gas to the Alliance Pipeline; and Aux Sable Canada (ASC), which operates the Heartland Offgas Plant in Fort Saskatchewan, Alberta (serving Western Canadian heavy oil upgraders and refiners) and the wholly owned Septimus Pipeline in Northeastern British Columbia, which transports liquids-rich gas from the Montney Shale Area into the Alliance system. The core technology platform is NGL extraction and fractionation at the eastern terminus of the Alliance Pipeline — a dense-phase gas pipeline that delivers rich gas from Western Canada to Channahon — supplemented by gas conditioning, pipeline transportation, offgas processing, and a fleet of approximately 300 leased rail cars that load 6,000+ cars per year to distribute NGL products to US and Canadian markets. Since commencing operations in December 2000, the Channahon facility has processed over 7.3 Tcf of natural gas and produced over 13 billion gallons of specification NGL products.
Aux Sable earns revenue primarily through negotiated tolling arrangements with shippers on the Alliance Pipeline system, charging transaction fees for NGL extraction and fractionation services, and through managed midstream services — construction and operation of customized processing plants and pipelines — for natural gas producers and heavy oil upgraders. Customer segments are concentrated in upstream natural gas producers with liquids-rich reserves (primary) and Western Canadian heavy oil upgraders and refiners (secondary). Distribution flows through the Alliance Pipeline for upstream gas intake, the Prairie Rose and Septimus pipelines as feed systems, and rail transportation for outbound NGL product delivery. Pricing is opaque: terms are private and negotiated, with no publicly disclosed fee schedules.
In April 2024, Pembina Pipeline Corporation completed its acquisition of Enbridge's interest in Alliance/Aux Sable, achieving 100% ownership consolidation of all Aux Sable assets and enabling fully coordinated growth with Pembina's broader integrated midstream platform. Aux Sable employs 251–500 staff across its primary sites in Illinois, North Dakota, Alberta, and British Columbia.

Aux Sable partnerships and signals
Strategic signalPartnerships
One partnership is on record.
- Alliance PipelinecoreAux Sable was established in December 2000 as part of the Alliance Pipeline system. The Alliance Pipeline transports liquids-rich gas from Western Canada to Aux Sable's Channahon facility where all gas is processed. The partnership is fundamental to Aux Sable's operations - all gas delivered via Alliance Pipeline is processed at ASLP's Channahon NGL Facility. Two companies were established - Aux Sable Liquid Products (US) and Aux Sable Canada - to manage the NGL business associated with Alliance Pipeline. In 2024, Pembina fully consolidated ownership of all Aux Sable assets.

Aux Sable competitors and assessment
Company assessmentDirect peers
- MPLX LP: MPLX is a diversified midstream operator with significant NGL processing, fractionation (Cincinnati, complex), transportation, and storage assets. Comparable integrated NGL value-chain operator to Aux Sable serving similar producer and shipper counterparties.
- ONEOK Inc. ONEOK operates one of the largest NGL gathering, processing, fractionation, and transportation systems in the US, with significant operations across Mid-Continent, Permian, and Rocky Mountain basins. Directly comparable integrated NGL value-chain operator to Aux Sable.
- DCP Midstream LP: DCP Midstream is one of the largest natural gas and NGL gatherers/processors in the US, with operating fractionation capacity serving the Permian, Mid-Continent, and other basins. Closely comparable NGL processing and fractionation franchise to Aux Sable.
- Keyera Corp. Keyera is a Canadian midstream operator with gathering, processing, and NGL fractionation assets primarily in Alberta. Most directly comparable to Aux Sable's Canadian operations (Heartland Offgas, Septimus) given shared Western Canadian Sedimentary Basin exposure and integrated processing-fractionation model.
- Enterprise Products Partners L.P. Enterprise Products is one of the largest NGL fractionators in North America with extensive pipelines and export terminals. Both companies run large-scale NGL processing and fractionation operations tied to natural gas streams and rely on a similar hub-and-spoke business model.
- Energy Transfer LP: Energy Transfer operates Sunoco NGL pipelines, fractionation, and export terminals across the US. Both companies are integrated NGL midstream players with comparable processing, fractionation, and downstream distribution infrastructure.
- Targa Resources Corporation: Targa Resources is a leading US midstream company operating NGL gathering, processing, and fractionation assets in key shale basins. Both companies operate integrated NGL extraction/fractionation businesses serving liquids-rich gas producers under similar toll/keep-whole commercial structures.
Broad incumbents
- Kinder Morgan Inc. Kinder Morgan is one of the largest North American energy infrastructure operators, with significant natural gas pipeline and processing operations. Overlaps with Aux Sable in gas processing and gathering services, though its core franchise is long-haul pipeline transmission rather than NGL fractionation.
- Williams Companies Inc. Williams is a large diversified midstream operator with natural gas processing, NGL fractionation (especially via its Mt. Pleasant complex), and gathering pipelines across the US. Comparable gas processing and fractionation capabilities to Aux Sable, though Williams operates a broader portfolio beyond NGL/frac.
Others
- Pembina Pipeline Corporation: Pembina is the 100% owner/parent of Aux Sable and operates adjacent integrated midstream assets (gas processing, NGL/fractionation, pipelines). Included as a structural/strategic reference rather than a competitor, since Aux Sable now consolidates fully into Pembina's midstream segment.
