NGTL System
As one of Canada's largest energy networks, the NGTL System connects natural gas from the Western Canadian Sedimentary Basin to communities, businesses, industries and export markets that help power Canada's economy.
Meeting demand. Expanding opportunity.
NGTL is the backbone of Alberta's natural gas network and a critical part of Canada’s energy system. Moving an average of ~15 billion cubic feet (Bcf) of natural gas each day, the NGTL system gathers gas from producers across the province and connects it to a vast network of markets, storage facilities and export connections across Canada and the United States.
As the central gathering and transportation hub for Western Canadian natural gas, NGTL connects supply to customers, downstream pipeline systems and LNG export pathways. Through these connections, Canadian natural gas reaches homes, businesses and industries across North America and global markets. The system supports energy security, economic growth, power generation, industrial development and Canada's evolving export opportunities.

- Greenview - A 15 kilometer loop expansion within the Municipal District of Greenview No. 16
Connecting what's next
As demand for reliable energy continues to grow, investments in the NGTL System will play a critical role in connecting Canadian resources to market and create the pathways that will allow Canada to compete, grow and diversify its economic future.
How are we regulated?
The NGTL System, an integrated natural gas transportation network that connects supply to Canadian and international markets through pipeline systems that cross provincial boundaries, is governed by the Canada Energy Regulator (CER) and associated regulations.
From a commercial perspective, the NGTL System operates under terms and conditions of the NGTL System Rate Design and Services Settlement approved in September 2024 through the RH-001-2019 Decision, as well as the provisions of the 2020-2024 Revenue Requirement Settlement approved in August 2020 through Order TG-009-2020. Together, these Settlements provide the basis for determining applicable rates and service provisions on the NGTL System.
We are pleased that the CER approved the components of these settlements 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, rates and services.
