NGTL System

Natural Gas Icon


This is our natural gas gathering and transportation system for the WCSB, connecting most of the natural gas production in western Canada to domestic and export markets. We believe we are very well positioned to connect growing supply in northeast B.C. and northwest Alberta. It is these two supply areas, along with growing demand for firm transportation in the oil sands area and to our major export points at Empress and Alberta/B.C. delivery locations, that is driving our large capital program for new pipeline facilities. The NGTL System is also well positioned to connect WCSB supply to potential LNG export facilities on the Canadian west coast.

The NGTL System currently has a $9.9 billion infrastructure program underway to add 3.5Bcf/d of incremental delivery capacity between 2020 to 2024. This additional capacity will help meet growing need for natural gas in North American and global markets, including the potential to supply LNG export facilities in Canada.

Criss-crossing Alberta and northeast British Columbia, gathering and shipping natural gas from the Western Canada Sedimentary Basin (WCSB), the NGTL System supplies natural gas to millions of Canadians and Americans every day. The NGTL System transports natural gas within Alberta and northeastern BC and connects with TC Energy’s Canadian Mainline, Foothills System, and other third-party pipelines.

How are we regulated

The NGTL System is governed according to regulations outlined by the Canada Energy Regulator (CER).

On June 25, 2018, TC Energy Corporation announced that its wholly-owned subsidiary, NOVA Gas Transmission Ltd. (NGTL), had received National Energy Board (NEB) approval for its 2018-2019 Revenue Requirement Settlement, which establishes the annual costs required to operate the NGTL System.

The settlement covers all NGTL System operating costs for the two-year term, including return on equity and depreciation. It also includes a mechanism that incentivizes NGTL to remain strongly focused on cost management as well as operating efficiencies and system reliability. The agreement:

  • encompasses a two-year period from January 1, 2018 to December 31, 2019;
  • fixes the equity return at 10.1 per cent on 40 per cent deemed common equity;
  • establishes depreciation at a forecast composite rate of 3.45 per cent;
  • fixes operating, maintenance and administration (OM&A) costs at $225 million for 2018 and $230 million for 2019, and includes a sharing mechanism that incents NGTL to achieve cost efficiencies; and,
  • provides for flow-through treatment of all other costs including pipeline integrity expenses and emissions costs.

We are pleased that the NEB approved the components of the settlement as filed. We worked diligently with our stakeholders through a collaborative process to reach this consensus that will provide greater certainty and stability to our operating costs and tolls through the end of 2019.”
