Natural Gas Icon



The Western Canada Sedimentary Basin (WCSB) is one of North America’s most prolific natural gas production basins and is of key importance to the Canadian economy.

Given the production of natural gas in Alberta and B.C., an important requirement for WCSB producers is getting their product into other markets. To be competitive, access to markets through well-positioned pipeline assets is critical.

Natural gas producers have asked us to increase natural gas transportation service on the NGTL System. To address this need, the 2021 NGTL System Expansion Project is now under construction, beginning in northwest Alberta and along the west path of the NGTL System and southeast towards Rocky Mountain House.

In total, we will add approximately 344 kms (214 miles) of newly built 1200 mm (48-inch) pipe to the NGTL System.

The pipeline sections start in the County of Grande Prairie, extending through the Municipal District of Greenview No. 16, Yellowhead County, and end in Clearwater County. Many of the pipeline sections will run parallel to the existing system and connect and connect at existing locations on the existing system.

In addition to the pipeline sections planned, NGTL is constructing three 30-megawatt (MW) compressor station unit additions on the NGTL System at the existing Nordegg, Didsbury, and Beiseker Compressor Stations. These facilities are located in Clearwater County, Mountain View County, and Rockyview County, respectively.

In total, the Project will add multiple pipeline sections and compressor station unit additions to our existing assets in three key areas:

  • Grande Prairie West Area
  • Grande Prairie South Area
  • Edson South Area

On February 19, 2020, the CER issued a report recommending that the Governor in Council (GIC) approve the 2021 NGTL System Expansion Project. The GIC directed the CER to issue an approval the Project on October 19, 2020, and the CER issued that approval (Certificate GC-129) on October 23, 2020. NGTL is progressing construction activities in accordance with regulatory requirements, with compressor station work completed and mainline pipeline construction activities under construction.

Once facilities are placed in service, the 2021 NGTL System Expansion Project will provide 1.59 PJ/d (1.45 Bcf/d) of incremental system capacity underpinned by long-term receipt and delivery contracts, connecting incremental supply to growing intra-basin and export markets. In-service is expected through 2021, with all Project components expected to be completed by April 2022.

Virtual Open House

Normally we'd be hosting pre-construction open houses for the NGTL 2021 System Expansion Project in local communities throughout Alberta, but in light of the COVID-19 pandemic, we've gotten creative to make sure our stakeholders, landowners and Indigenous groups still have an opportunity to connect with us.

We invite you to visit the virtual open house to learn all about this critical project, view the interactive map and submit feedback or questions.

Documents and maps

The pipeline additions will generally follow our existing NGTL pipeline corridors in western Alberta. The routes we’ve chosen would add multiple pipeline sections to our existing assets along our Grande Prairie Mainline and Edson Mainline pipeline assets. For a detailed view of the route, please visit our virtual open house.

Regulatory documents

How are we regulated?

The 2021 NGTL System Expansion Project is governed according to regulations outlined by the Canada Energy Regulator (CER), which replaced the National Energy Board (NEB) on August 28, 2019. For more information about the CER web site.

Project Application

If you would like to view NGTL application submissions to the CER they can be accessed on the CER’s 2021 NGTL System Expansion Project website.

If you require assistance accessing the files, you can also contact our Provincial and Community Relations team at public_affairs_ca@tcenergy.com and we will assist you.

Plan, Profile and Book of Reference  (PPBoR)

NGTL will file the Plan, Profile, and Book of Reference (PPBoR) with the CER, which reflects engagement and feedback received to date on the detailed routing. All landowners affected by the Project will receive information on the PPBoR and have the opportunity to comment on the final route before it is approved by the CER.

For additional information, visit the CER website.


About the NGTL System

In Canada, we have a very large natural gas source known as the Western Canada Sedimentary Basin (WCSB) in addition to smaller natural gas sources. The NGTL System is a 25,000-km (15,000-mile) pipeline system located primarily throughout Alberta and northeast British Columbia – where the WCSB is located – and connects with other pipeline systems to deliver gas across North America. According to the Canadian Gas Association, natural gas meets 35 per cent of Canada’s energy needs through heat and power.
