Edson Mainline Expansion Project

TransCanada – Oil & Liquids


The pipeline expansion project in western Alberta is required to expand pipeline capacity for the transportation of natural gas to growing markets located in central and southern Alberta from the Peace River Project Area.

The proposed Project consists of two pipeline components which would add up to approximately 85 kilometres (km) of newly constructed 48-inch pipe to the NGTL System, as well as a compressor station unit addition.

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.

The Alford Creek section consists of approximately 45 km of 48-inch pipeline located 29 km west from Rocky Mountain House, in Clearwater County.

NGTL is also proposing a unit addition at the existing Princess Compressor Station located approximately 30 km northeast of Brooks, Alberta, in the County of Newell.

This Project is part of TransCanada’s $1.5 billion expansion to the NGTL System to connect WCSB supply to incremental market demand. Read more

Community Benefits

The proposed project will deliver well-designed and constructed infrastructure that provides short term and long term economic benefits and strengthens the economy on a local, provincial and national level.

Employment Opportunities – Construction will require the services of equipment operators, welders, mechanics, truck drivers, labourers and more.

Business Opportunities – Pipeline construction will create demand for local goods and services including food and accommodation, hardware, industrial parts, automotive parts and servicing, fuel and more.

Annual Revenue to Support Local Services – Project construction will result in tax payments to municipal, provincial and federal governments. When the project is operational, annual tax payments will help support schools and hospitals, emergency services, recreation facilities, recycling programs and other local programs vital to sustaining communities.

Investments in Local Communities – Through our engagement with local communities, we will identify areas where we can help build stronger, more vibrant communities through initiatives with community partnerships in the areas of safety, community and environment.
