Sunrise Expansion Program

Westcoast Energy Limited Partnership (Westcoast), an Enbridge affiliate, owns and operates British Columbia’s major natural gas transmission system referred to as the Westcoast Pipeline system.

This system transports processed natural gas to consumers throughout the province, Alberta and the U.S. Pacific Northwest.

This gas is ultimately used to heat homes, businesses, hospitals and schools. It is also used as a fuel for electric power generation and is a staple in many industrial and manufacturing processes.

Following a successful open season in 2022 that resulted in requests for additional transportation capacity, Westcoast is proposing the Sunrise Expansion Program (Project), an expansion of the southern portion of the Westcoast system, known as T-South.

The proposed Project includes the installation of pipeline loops and additional compression at select existing compressor station sites. Westcoast is proposing the use of electric-driven compressors, which would require new powerline infrastructure.

The Project will provide up to 300 million cubic feet per day (MMcf/d) of additional natural gas transportation capacity on the T-South system.

The targeted in-service date is late 2028.

Westcoast filed a regulatory application with the Canada Energy Regulator in Q2 2024. To support its application, environmental, geotechnical, and socio-economic studies are underway. These studies help determine the specific configuration, location, and timing of any new facilities, including compressor station upgrades and pipeline loops.

We are engaging with Indigenous groups, landowners and local communities as we move the Project forward.
