The Aux Sable Story
Aux Sable’s vision is to be a market leader in the midstream gas processing and NGL industry within selected regions of North America where Aux Sable can profitably develop and expand competitive advantages.
Aux Sable was established as a key part of the Alliance-Aux Sable dense phase gas system that commenced operation on December 1, 2000. Two companies were established, one in the U.S. (Aux Sable Liquid Products or “ASLP” located in Channahon, Illinois) and one in Canada (Aux Sable Canada or “ASC” located in Calgary, Alberta) to manage the natural gas liquids (NGLs) business associated with the Alliance Pipeline. In 2010, a second U.S. company Aux Sable Midstream or "ASM" was established to focus on other midstream developments in the United States. ASLP and ASM are both owned by Enbridge (42.7%), Veresen (42.7%) and Williams (14.6%). ASC is equally owned by Enbridge and Veresen.
Aux Sable derived its corporate name from the township where it located the Channahon NGL extraction and fractionation facility in 1996 as part of the Alliance project. Aux Sable Township itself was named by the original French Canadian settlers who traveled to and from the sand bar on the local creek to access water…”aux sable” means “to the sand” in French.
Aux Sable has the exclusive right to extract NGLs from Alliance Pipeline gas. The company is well positioned to pursue its vision through development of opportunities to optimize the advantages inherent in the Alliance dense phase energy delivery system as well as growth opportunities outside of its exclusive NGL position in the Alliance gas/NGL transport system.
Aux Sable has now been in operation for over ten years and has delivered outstanding operating, safety and environmental results. The company continually strives to meet high standards in these areas, to comply with appropriate financial/business controls and to be a responsible participant in the local communities where it has operations.
Aux Sable USA
Aux Sable Liquid Products owns and operates one of the largest NGL extraction and fractionation plants in North America. The facility is located in Channahon, Illinois about 50 miles southwest of Chicago near the eastern terminus of the Alliance pipeline. Operations commenced December 1, 2000. The facility is capable of processing 2,100 mmcfd of gas and can produce about 102,000 barrels per day of specification NGL products. All of the Alliance gas is processed at ASLP’s Channahon NGL Facility.
Aux Sable Midstream owns and operates the Palermo Conditioning Plant and the Prairie Rose Pipeline. The Prairie Rose Pipeline connects the Palermo Plant to Alliance Pipeline, which delivers high energy dense phase gas to Aux Sable's Channahon, Illinois Plant for processing. ASM is pursuing other NGL processing and infrastructure midstream initiatives, primarily driven by the shale oil and shale gas developments in the midwest and northeast United States.
Aux Sable Canada
Aux Sable Canada is an active midstream player in Western Canada, primarily along the Alliance Pipeline corridor. Through the Alliance-Aux Sable dense phase gas system, ASC provides value added solutions for producers to effectively develop and produce NGL rich gas reserves. Since inception, the company has successfully attracted rich gas to Alliance through inducements and new rich gas connections. ASC's strategy also includes building, owning and operating offgas processing facilities for the heavy oil upgrading and refining industry in Alberta.
The Alliance Pipeline high pressure, dense phase system consists of over 2,000 miles of 36 inch mainline pipe and over 280 miles of gathering pipe connected to 48 gas plants in northwestern Alberta and northeastern B.C. These plants have a design capacity in excess of 2600 million cubic feet per day (mmcfd). Alliance currently has a capacity of approximately 1590 mmcfd on an annualized basis through its mainline of which 1325 mmcfd is the base throughput capacity guaranteed by Alliance under ship or pay contracts with an initial term of 15 years (2001 to 2015). Alliance is equally owned by Enbridge and Veresen.
