Pipeline Profiles: NOVA Gas Transmission Ltd. (NGTL)

Pipeline system and key points

Updated September 2018

NOVA Gas Transmission Ltd. pipeline system map

NOVA Gas Transmission Ltd. owns the NGTL system, a natural gas gathering and transportation system in Alberta and northeastern British Columbia. NGTL transports natural gas produced in the Western Canadian Sedimentary Basin to markets in Canada and the United States. The pipeline commenced operations in 1957 and NGTL came under NEB jurisdiction in 2009. Prior to that date, NGTL was under provincial jurisdiction and regulated by the Alberta Utilities Commission (AUC) and its predecessors.

NGTL has over 1 100 receipt points and over 300 delivery points. NEB-regulated assets include approximately 24 500 km of pipeline and various auxiliary infrastructure.

In 2016, NGTL delivered over four trillion cubic feet of natural gas. This equates to 11 billion cubic feet per day (Bcf/d) or 311 million cubic metres per day (million m³/d). Approximately 40% of deliveries in 2016 were in Alberta and B.C, 19% went to markets in the Pacific Northwest and California, 19% to the Midwestern United States, and 22% to Eastern Canada and the U.S. through various interconnected pipelines.

Key points on NGTL include:

  • East Gate – In the southeastern portion of the NGTL system, the East Gate interconnects with TransCanada's Canadian Mainline (near Empress, Alberta) and TransCanada's Foothills Pipeline (near McNeill, Alberta).
  • West Gate – In the southwestern portion of the NGTL system, the West Gate interconnects with TransCanada's Foothills Pipeline (British Columbia).
  • Upstream of James River – Throughputs in the northwestern portion of the NGTL system. Upstream of James River flows contain receipts from the Horn River and the Groundbirch pipelines (part of NGTL).
  • North and East – Throughputs to delivery areas in northern Alberta, including natural gas used for oil sands operations.

NGTL is expanding at a rapid pace. New supply has entered the system, particularly from the Montney formation in the northwest portion of the system. In mid-2017, NGTL announced it has a $7.1 billion near-term capital program targeted for completion by 2021.

In September 2016, the Board approved the Towerbirch Expansion Project [Folder 2819218]. The project was underpinned by 859 million cubic feet per day (MMcf/d) or 24 million m³/d of new receipt firm service requests and entailed construction of approximately 87 km of new natural gas pipeline and associated facilities in northwest Alberta and northeast British Columbia. The project consisted of two sections: the Tower Lake Section and the Groundbirch Mainline Loop. The sections came online in October 2017 and November 2017, respectively.

In June 2016, the Board approved the 2017 NGTL System Expansion Project [Folder 2758964]. The project was under pinned by approximately 318 MMcf/d (9.0 million m³/d) of new firm transportation delivery contracts and 222 MMcf/d (6.3 million m³/d) of new firm transportation receipt contracts. The project required construction of 230 km of pipeline in five pipeline section loops, as well as two compressor stations. The project is coming online in stages, starting in the summer of 2017.

In March 2017, NGTL applied for the Sundre Crossover Project [Folder 3225032]. The project is underpinned by 232 MMcf/d (6.1 million m³/d) of new firm transportation delivery contracts to the Alberta-BC export point and entails construction of 21 km of new pipeline near the town of Sundre, Alberta.

Official Board documents related to the construction, operation and maintenance of the NGTL pipeline can be found here: NGTL regulatory documents [Folder 554112].

Condition Compliance

Updated September 2018

Every pipeline company in Canada must meet federal, provincial or territorial, and local requirements. This includes Acts, Regulations, rules, bylaws, and zoning restrictions. Pipelines are also bound by technical, safety, and environmental standards along with company rules, protocols and management systems. In addition to these requirements, the Board may add conditions to regulatory instruments that each company must meet. Condition compliance is monitored by the Board and enforcement action is taken when required. For a detailed list of conditions that NGTL must meet, and their status, please see the condition compliance table and search for “NOVA Gas Transmission Ltd.”

Safety Performance

Updated September 2018

The Board holds the companies it regulates accountable to protect the safety of Canadians and the environment. As part of this accountability, companies must report events such as incidents and unauthorized activities to the Board. For a summary of pipeline incidents and unauthorized activities on the NGTL pipeline since 2008, visit the Safety performance dashboard and select “NOVA Gas Transmission Ltd.”

Emergency Management

Updated September 2018

The NEB checks to make sure companies are keeping pipelines safe by doing inspections, in-depth safety audits, and other activities. Yet, even with these precautions, an emergency could still happen. Sound emergency management practices improve public safety and environmental protection outcomes, and provide for more effective emergency response.

The NEB holds its regulated companies responsible for anticipating, preventing, mitigating, and managing incidents of any size or duration. Each company must have an emergency management program that includes detailed emergency procedures manuals to guide its response in an emergency situation. We oversee the emergency management program of a regulated company’s projects until they cease to operate.

The Board requires companies to publish information on their emergency management program and their emergency procedures manuals on their websites so Canadians can access emergency management information.

Throughput and capacityFootnote 1

Updated September 2018

A toll is the price charged by a pipeline company for transportation and other services. Tolls allow pipeline companies to safely operate and maintain pipelines. Tolls also provide funds for companies to recover capital (the money used to build the pipeline), pay debts, and provide a return to investors.

The interactive graph below shows the NGTL tolls on major paths since 2009. These tolls are calculated using the receipt firm transportation average demand rate (3-year term) plus delivery firm transportation demand rate (1-year term) to major delivery points. Major delivery points include Empress/McNeill border where NGTL connects with the TransCanada Mainline and Foothills Saskatchewan; the Alberta-BC border where NGTL connects with Foothills BC; and the Gordondale border/Boundary Lake border. Tolls on NGTL have been increasing since 2012, particularly with expansions to enable increasing throughputs. The combination of higher throughput and billing determinants in 2018 and a substantive regulatory amortization credit that was carried over from 2017 to 2018 resulted in NGTL’s 2018 final tolls being six to 11 per cent lower than the comparable 2017 tolls.

Open data can be freely used and shared by anyone for any purpose. The data for these graphs are available.

Tolls on NGTL are based on a cost of service model. Customers contract separately for receipt and delivery services. In August 2010, the Board approved a new tolls design methodology for NGTL (RHW-1-2010) [Filing A25890]. New tolls came into effect on 1 November 2010. Under the revised toll methodology, delivery tolls on NGTL are calculated depending on the distance and service offering. Receipt tolls on NGTL are location-specific and are subject to pricing floors and ceilings. NGTL operated under revenue requirement settlements for 2010 to 2018.

Abandonment funding

Updated May 2018

The Board requires all pipelines to set aside funds to safely cease operation of a pipeline at the end of its useful life. In 2016, NOVA Gas Transmission Ltd. estimated it would cost approximately $2.5 billion to do this. These funds will be collected over 30 years and are being set aside in a trust. Official Board documents related to abandonment funding can be found here, sorted by year and by company: abandonment funding documents [Folder 3300366].

Pipeline financial information

Updated March 2018

Pipeline companies report important financial information to the Board quarterly or annually. A solid financial position enables companies to maintain their pipeline systems, attract capital to build new infrastructure, and meet the market’s evolving needs.
