The Edson Mainline Expansion project is now in service.
NOVA Gas Transmission Ltd. (NGTL), a wholly owned subsidiary of TransCanada PipeLines Limited, an affiliate of TC Energy Corporation, constructed, owns and operates the Edson Mainline Expansion Project to provide pipeline capacity for the transportation of natural gas to growing markets located in central and southern Alberta from the Peace River Project Area.
The Project consisted of two pipeline components adding up to approximately 85 kilometres (km) of newly constructed 48-inch pipe to the NGTL System.
The Elk River section consists of approximately 40 km of 48-inch pipeline located 115 km southeast from Hinton, Alberta, in Yellowhead and Clearwater County. This section went into service on October 7, 2022.
The Alford Creek section is approximately 45 km of 48-inch pipeline located 29 km west from Rocky Mountain House, in Clearwater County. This section went into service on October 31, 2022.
NGTL submitted an application to the National Energy Board (NEB), predecessor to the Canada Energy Regulator (CER), under Section 52 of the NEB Act in Q2 2019 for permission to construct, own and operate the project. On November 19, 2020, the CER issued a report recommending that the Governor in Council (GIC) approve the project.
This Project was part of TC Energy’s $1.5 billion expansion to the NGTL System to connect WCSB supply to incremental market demand. Read more.
