Project Information

NOVA Gas Transmission Limited (NGTL), a wholly owned subsidiary of Trans Canada, has filed an application for the 2021 NGTL System Expansion Project. A project description is not an application; it provides preliminary information about an application the company expects to file at a later date. NGTL proposes to build and operate approximately 350 km of 1,219 mm (NPS 48) outside diameter natural gas pipeline and associated facilities in northwestern Alberta. If approved, the project would “loop” or add new pipeline parallel or adjacent to, the existing NGTL System.

The Project includes three main areas:

Grande Prairie West Area:

  • Grande Prairie Mainline Loop No. 4 (Valhalla Section), approximately 38 km; and,
  • Grande Prairie Mainline Loop No. 3 (Elmworth Section), approximately 47 km.

Grande Prairie South Area:

  • Grande Prairie Mainline Loop No. 2 (Karr Section), approximately 57 km;
  • Grande Prairie Mainline Loop No. 2 (Deep Valley Section), approximately 68 km; and,
  • Grande Prairie Mainline Loop No. 2 (McLeod River Connection Section), approximately 15 km.

Edson South Area:

  • Edson Mainline Loop No. 4 (Rob Section), approximately 42 km;
  • Edson Mainline Loop No. 4 (Dismal Creek Section), approximate4ly 33 km;
  • Edson Mainline Loop 4 (Brewer Section), approximately 50 km;
  • Three compressor station unit additions at Nordegg, AB, Didsbury, AB and Beiseker, AB; and,
  • January Creek Control Valve and associated pipeline tie-ins.

In its application, NGTL said the project was needed to transport natural gas from areas of increasing production in northwestern Alberta and northeastern BC to intra-Alberta and export markets. If approved, NGTL plans to begin operating the project by April 2021.
