Project Scope
Pipeline loops
A total of approximately 137 km of 42-inch pipeline looping in various segments along the system is currently anticipated in order to increase natural gas transportation capacity. The pipeline loops would be added along Westcoast’s existing right-of-way (ROW). The additional loop segments will run parallel and connect to the existing pipeline system.
Compressors and infrastructure upgrades
Westcoast plans to install new compressors at existing compressor stations located at Azouzetta Lake (CS-2B), 93 Mile (CS-6B), Kingsvale (CS-8A), and Othello (CS-8B).
To reduce environmental impacts, Westcoast is considering the use of electric-driven compressor units for some of the compression required for the Project. If electric-driven compressor units are used, the Project could prevent about 360,000 tonnes of carbon dioxide equivalent (CO2e) emissions per year. That is equivalent to removing 100,000 cars off the road in a year.
To power the new electric-driven compressor units and ensure reliable operations, up to approximately 34 km of new electric transmission powerlines may be required. These overhead powerlines would largely follow existing linear infrastructure such as roads or rights-of-way to minimize environmental and local community impacts.
