TC Energy


TC Energy Corporation is a North American energy company, headquartered in Calgary, Alberta. The company builds and operates energy infrastructure across Canada, the United States, and Mexico, with core business segments in Natural Gas Pipelines, Power Generation and Energy Storage.
TC Energy's natural gas pipeline network spans approximately, transporting over 30% of the natural gas consumed across North America. The company also holds ownership interests in seven power generation facilities with a combined capacity of 4,650 megawatts, including nuclear and natural gas-fired assets.
In addition to its pipeline and power operations, TC Energy maintains strategic investments in energy infrastructure that support liquefied natural gas exports to global markets. Its assets contribute to the delivery of affordable, reliable, and lower-emission energy across the continent.
The company was founded in 1951 in Calgary. The company's US headquarters is located in the TC Energy Center skyscraper in Houston, Texas.
TC Energy is the largest shareholder in, and owns the general partner of, TC PipeLines.

History

The company was incorporated in 1951 by a Special Act of Parliament as Trans-Canada Pipe Lines Limited. In 1954 N. Eldon Tanner, president of Merrill Petroleums and former Alberta legislator, became president of the company. The purpose of the company was to develop the TransCanada pipeline to supply eastern Canadian markets with natural gas produced in the west.
In 1998, TransCanada Pipelines merged with NOVA Corporation's pipeline business, keeping the TransCanada name and becoming "the fourth largest energy services company in North America".
Seeking to expand its presence in the United States, in 2016, TransCanada acquired Columbia Pipeline Group for US$13 billion from NiSource's Shareholders. The CPG acquisition added a pipeline network in Pennsylvania and surrounding states, where the Marcellus and Utica shale gas formations are located.
In May 2019, the company changed its name from TransCanada Corporation to TC Energy Corporation to better reflect the company's business, which includes pipelines, power generation and energy storage operations in Canada, the United States and Mexico.
In October 2019, the 56-story Bank of America Center skyscraper in Houston, Texas was renamed as TC Energy Center and serves as the company's US headquarters.
On October 1, 2024, TC Energy completed the spinoff of its Liquids Pipelines business creating an independent company, South Bow, focused on crude oil pipelines.

Operations

Natural gas pipelines

TC Energy's natural gas pipelines business builds, owns and operates a network of natural gas pipelines across North America that connects gas production to interconnects and end use markets. The company transports over 30% of continental daily natural gas demand through approximately 94,000 km of pipelines. In addition, the company owns 532 Bcf of natural gas storage facilities, making TC Energy one of the largest natural gas storage providers in North America. This segment is TC Energy's largest segment, generating approximately 87% of the company's EBITDA in 2024. The Natural Gas Pipelines business is split into three operating segments: Canadian Natural Gas Pipelines, U.S. Natural Gas Pipelines, and Mexico Natural Gas Pipelines.
The major pipeline systems include:
  • NGTL System A wholly owned subsidiary, NOVA Gas Transmission Ltd., connects gas producers in the Western Canadian Sedimentary Basin with consumers and exports. TC Energy has the largest and most extensive natural gas network in Alberta.
  • Canadian Mainline This pipeline serves as a long haul delivery system transporting natural gas from the Western Canadian Sedimentary Basin across Canada to Ontario and Québec to deliver gas to downstream Canadian and U.S. markets. The pipeline has evolved accommodate additional supply connections closer to its markets. The mainline is over 60 years old
  • Columbia Gas This natural gas transportation system serves the Appalachian Basin, which contains the Marcellus and Utica plays, two of the largest natural gas shale plays in North America. The system also interconnects with other pipelines that provide access to the U.S. Northeast and the Gulf of Mexico.
  • ANR Pipeline System This pipeline system connects supply basins and markets throughout the U.S. Midwest, and south to the Gulf of Mexico. This includes connecting supply in Texas, Oklahoma, the Appalachian Basin and the Gulf of Mexico to markets in Wisconsin, Michigan, Illinois and Ohio. In addition, ANR has bi-directional capability on its Southeast Mainline and delivers gas produced from the Appalachian basin to customers throughout the Gulf Coast Region.
  • Columbia Gulf — This pipeline system was originally designed as a long haul delivery system transporting supply from the Gulf of Mexico to major demand markets in the U.S. Northeast. The pipeline is now transitioning to a north-to-south flow and expanding to accommodate new supply in the Appalachian Basin and its interconnects with Columbia Gas and other pipelines to deliver gas to various Gulf Coast markets.
  • Mexico Pipeline Network — This consists of a network of natural gas pipelines in Mexico.
  • Southeast Gateway Pipeline — A marine pipeline that will transport natural gas, connecting the supply from Tuxpan, Veracruz, to delivery points in Coatzacoalcos, Veracruz, and in Paraíso, Tabasco.
  • Coastal Gaslink Pipeline Project – Coastal Gaslink delivers natural gas from the Dawson Creek area to a facility near Kitimat, where LNG Canada prepares it for export to global markets by converting the gas to a liquefied state—also known as liquefied natural gas.

    Energy

TC Energy's Energy division consists of power generation and unregulated natural gas storage assets. The power business consists of approximately 4,650 megawatts of generation capacity owned or under development. These assets are located primarily in Canada and are powered by natural gas, nuclear, and wind.
  • Western Power These assets include approximately 1,000 MW of power generation capacity through four natural gas-fired cogeneration facilities in Alberta and one in Arizona.
  • Eastern Power These assets include approximately 2,900 MW of power generation capacity in Eastern Canada.
  • Bruce Power This operates the Bruce Nuclear Generating Station in Ontario. Comprising eight nuclear units with a combined capacity of approximately 6,400 MW, it is currently the largest operating nuclear power plant in the world. TC Energy holds a 48.4% interest in the asset.
  • Saddlebrook Solar + Storage project in Aldersyde, Alberta consisting of 81 MW of solar generation with utility-scale energy storage.
TC Energy has proposed two pumped storage projects to store and supply clean energy. The Ontario Pumped Storage Project near Meaford, Ontario would provide 1000 MW of clean energy and the proposed Canyon Creek Pumped Storage Project near Hinton, Alberta would provide 75 MW of clean energy.

Ownership

As of September 2025, 84% of the share capital of TC Energy is owned by institutional investors. The dominant shareholder is the Royal Bank of Canada, which owns over 12% of the company. The top 10 shareholders hold ~40% of total shares outstanding.

Political activities

A former TC Energy executive, in an internal meeting for external relations staff, claimed that the firm had played a central role in excluding pipelines from the scope of provincial legislation in British Columbia, Canada. A TC Energy representative described the claims as exaggerated and untrue.
In 2019 TC Energy aided the drafting of anti-protest legislation in South Dakota. The legislation, which Governor Kristi Noem signed into law in March 2019, created a fund to cover the costs of policing pipeline protests, and was accompanied by another law which sought to raise revenue for the fund by creating civil penalties for advising, directing, or encouraging persons participating in rioting. In response to the law Noem was sued by the Indigenous Environmental Network, Sierra Club, and other groups, who argued the laws violate First Amendment rights by incentivizing the state to sue protesters.
