The jurisdiction for this project is entirely within the Province of Alberta, which has well-established, constructive and efficient regulatory processes. Over a dozen letters of support from major employers, industry associations, economic development agencies and municipal governments were filed along with the application.
The Yellowhead Mainline project is expected to create approximately 2000 jobs during construction and will provide gas supply for the more than US$20 billion of investment and associated employment in Alberta by customers, including the Dow Fort Saskatchewan Path2Zero project.
The project consists of approximately 200-230 km of high-pressure natural gas pipeline and related control and compression facilities that will run from the Edson area to the northeast Edmonton area.
Since announcing the project in May 2024, ATCO Energy Systems has identified several potential routes and completed preliminary engineering to further refine the delivery capability and the scope to provide an initial cost estimate. The project is expected to have the capability to deliver about 1200 terajoules (1.1 billion f3)/d of incremental natural gas delivery capacity. Total investment for the project is estimated at US$2.8 billion and will be subject to further detailed engineering and tendering of supply contracts.
