TC Energy Corporation is a major North American energy infrastructure company headquartered in Calgary, Alberta. The company primarily operates an extensive network of natural gas pipelines and storage facilities across Canada, the United States, and Mexico. Its natural gas pipeline network spans approximately 94,000 kilometers, transporting natural gas from supply basins to local distribution companies, power generation plants, industrial facilities, and LNG export terminals. In addition to its midstream operations, TC Energy owns or has interests in several power generation facilities, including the Bruce Power nuclear plant in Ontario. In October 2024, the company spun off its liquids pipelines business into an independent publicly traded company, South Bow Corporation, to focus on its natural gas and power and energy solutions segments.
