NOVA Gas Transmission Ltd. – 2021 NGTL System Expansion Project

What’s New


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. NGTL proposes to build and operate approximately 344 km of 1,219 mm (NPS 48) outside diameter natural gas pipeline and associated facilities in northwestern Alberta, from approximately Grande Prairie to north of Calgary, including three compressor station additions. If approved, the project would “loop” or add new pipeline parallel or adjacent to, the existing NGTL System.

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.
