TC Energy Corporation, previously known as TransCanada Corporation, stands as a prominent player in the North American energy sector. Headquartered in Calgary, Alberta, Canada, within the iconic TC Energy Tower, the company specializes in the development and operation of energy infrastructure spanning across Canada, the United States, and Mexico. TC Energy operates through three primary segments: Natural Gas Pipelines, Liquids Pipelines, and Energy.

The Natural Gas Pipeline network encompasses an extensive network of 92,600 kilometers (57,539 miles) of gas pipelines, facilitating the transportation of over a quarter of North America’s natural gas demand. On the other hand, the Liquids Pipelines division includes 4,900 kilometers (3,045 miles) of oil pipelines, enabling the shipment of 590,000 barrels of crude oil daily, equivalent to approximately 20% of Western Canadian exports. Additionally, the Energy division boasts ownership or interests in 11 power generation facilities, collectively generating 6,600 megawatts (MW) of power, sourced from nuclear and natural gas-fired plants. Notably, TC Energy is expanding its energy division to incorporate more renewable sources like pumped storage, wind, and solar generation.

Established in 1951 in Calgary, TC Energy underwent a rebranding in 2019. Over its history, it has evolved through strategic mergers and acquisitions, notably merging with NOVA Corporation’s pipeline business in 1998 and acquiring Columbia Pipeline Group in 2016. The company’s US headquarters are situated in the TC Energy Center skyscraper in Houston, Texas.

TC Energy’s operations are diverse and expansive. Its natural gas pipelines span across North America, connecting gas production to various markets and end-users. Some of its major pipeline systems include the NGTL System, Canadian Mainline, Columbia Gas, ANR Pipeline System, and Columbia Gulf, among others. The company also has a significant presence in Mexico, with a growing network of natural gas pipelines.

In the realm of liquids pipelines, TC Energy’s Keystone Pipeline System and Grand Rapids pipelines are instrumental in connecting Alberta crude oil supplies to refining markets in the United States. The Keystone Pipeline System, despite facing opposition and controversy, has been pivotal in transporting Western Canadian crude oil to export markets. Additionally, TC Energy has ongoing projects like the Keystone XL Pipeline, aimed at further expanding its liquids pipeline infrastructure.

TC Energy’s Energy division focuses on power generation and natural gas storage assets. With a capacity of approximately 7,000 MW, its power generation facilities are primarily located in Canada and powered by natural gas, nuclear, and wind sources. The company has proposed projects in pumped storage and solar energy to bolster its clean energy portfolio.

As of February 2020, TC Energy’s ownership structure reflects a diverse shareholder base, with institutional investors holding a majority stake in the company. Notable shareholders include the Royal Bank of Canada and other prominent financial institutions.
