TC Energy operates one of North America’s largest natural gas pipeline and storage networks, spanning approximately 93,300 kilometres of pipeline infrastructure across Canada, the United States, and Mexico. The Calgary-based company moves roughly 25% of North America’s daily natural gas demand through its transmission systems, making TC Energy a foundational component of the continent’s energy supply chain — from Western Canadian gas fields through to US Gulf Coast LNG export terminals and Mexican industrial demand centres.
TC Energy: Company Overview
TC Energy is headquartered in Calgary, Alberta, and is listed on both the Toronto Stock Exchange and New York Stock Exchange. The company was formerly known as TransCanada Corporation — a name synonymous with the original TransCanada PipeLines system commissioned in 1958 — before rebranding to TC Energy in 2019 to reflect its broader North American footprint and diversified asset base beyond its Canadian origins.
TC Energy operates across three primary business segments: Canadian Natural Gas Pipelines, US Natural Gas Pipelines, and Mexico Natural Gas Pipelines. A fourth segment — Power and Energy Solutions — covers the company’s electricity generation assets and emerging energy transition investments. The company reported revenues of approximately CAD $15.7 billion in 2024, with the natural gas pipeline segments generating the majority of earnings through long-term regulated and contracted tariff structures.
Canadian Natural Gas Pipelines
TC Energy’s Canadian pipeline segment is anchored by the NGTL System — the Nova Gas Transmission Ltd network covering approximately 25,000 kilometres of gathering and transmission pipelines across Alberta and northeast British Columbia. The NGTL System collects gas from the Western Canadian Sedimentary Basin and delivers it to interconnection points for onward transmission east and west across Canada and south into the US market.
The original TransCanada Mainline extends approximately 14,000 kilometres from the Alberta border across Saskatchewan, Manitoba, Ontario, and Quebec to delivery points in Eastern Canada and interconnections with US pipeline systems. This system underpins natural gas supply to Canadian population centres and industrial facilities across the country’s most densely inhabited corridor.
TC Energy’s Canadian natural gas storage assets complement the transmission network, providing seasonal and operational flexibility for shippers managing supply and demand variability across the Canadian market. The role of underground gas storage in supporting pipeline network balancing is covered in depth in the Underground Gas Storage 2026: Global Capacity & Outlook analysis.
US Natural Gas Pipelines
TC Energy’s US pipeline segment comprises a network of interconnected transmission systems spanning the US Gulf Coast, Midwest, Northeast, and Southeast markets. Key assets include the ANR Pipeline system — approximately 17,700 kilometres of transmission pipeline serving Midwest and Gulf Coast markets — and the Columbia Gas Transmission and Columbia Gulf Transmission systems covering the Appalachian production region and its connections to Northeast demand centres.
The US segment underwent significant strategic review following TC Energy’s 2023 decision to separate its liquids pipeline business — including the Keystone Pipeline System — into a standalone entity now operating as South Bow Corporation. This separation, completed in October 2024, sharpened TC Energy’s focus on natural gas infrastructure and positioned the company as a pure-play gas pipeline and storage operator in the North American market.
TC Energy’s US gas pipeline assets interconnect with the broader North American transmission grid covered in the Top 10 Pipeline Companies in 2026 ranking, which maps the full competitive landscape of major gas and liquids transmission operators across the continent.
Mexico Natural Gas Pipelines
TC Energy’s Mexico segment operates approximately 4,900 kilometres of natural gas transmission pipelines serving industrial and power generation customers across northern and central Mexico. The company’s Mexican assets were developed under long-term capacity contracts with Comisión Federal de Electricidad (CFE) — Mexico’s state power utility — providing TC Energy with contracted revenue streams underpinned by sovereign counterparty exposure.
The Mexico segment has experienced contractual and payment disputes with CFE, which TC Energy has pursued through international arbitration processes. The resolution of these disputes and the long-term commercial framework governing TC Energy’s Mexican operations remain a material consideration for the company’s earnings outlook in the region.
Natural Gas Storage and Power Assets
TC Energy operates underground natural gas storage facilities in Canada and the United States, providing shippers with storage capacity to manage seasonal demand swings and supply variability. Storage is an integral element of the pipeline network’s commercial offering — shippers using TC Energy’s transmission systems can access adjacent storage capacity to optimise their supply chain economics across the annual demand cycle.
The company’s Power and Energy Solutions segment includes interests in nuclear generation through the Bruce Power partnership in Ontario — one of the largest operating nuclear facilities in the world — alongside natural gas-fired generation assets and emerging investments in carbon capture and hydrogen infrastructure. TC Energy has positioned its power assets as part of a longer-term energy transition strategy while maintaining its core focus on natural gas infrastructure earnings.
The role of natural gas storage in North American energy security is examined in the Top 10 Natural Gas Storage Companies ranking, which covers the major operators providing storage capacity across the US and Canadian markets that TC Energy’s pipeline network serves.
2026 Strategy and Capital Programme
TC Energy’s 2026 capital programme is focused on organic growth within its existing pipeline corridors — expansions of the NGTL System to accommodate growing Western Canadian gas production, incremental US pipeline capacity additions driven by LNG export demand on the Gulf Coast, and continued development of its Mexican contracted pipeline assets.
The company has identified approximately CAD $6–7 billion in annual capital expenditure as its near-term investment programme, funded through operating cash flow and selective asset monetisation. TC Energy has pursued a disciplined asset divestiture programme since 2023 — selling non-core assets to strengthen its balance sheet following the Keystone separation and a period of elevated capital deployment on large-scale projects including the Coastal GasLink pipeline in British Columbia.
Coastal GasLink — a 670-kilometre pipeline connecting Montney gas production in northeast BC to the LNG Canada liquefaction facility at Kitimat — was completed and commissioned in 2023, representing TC Energy’s largest single project delivery. LNG Canada’s first train commenced production in 2025, establishing Western Canada as a Pacific LNG export source and creating sustained long-term throughput demand on the Coastal GasLink system.
Competitive Position in North American Midstream
TC Energy competes with and interconnects with the major North American gas pipeline operators covered in the Top 10 Midstream Companies 2026 ranking — including Enbridge, Williams Companies, Energy Transfer, and Kinder Morgan, whose 83,000-kilometre US gas pipeline network is TC Energy’s closest comparable in scale and strategic positioning. The two companies’ networks interconnect at multiple points across the US-Canada border and compete for shipper volume on overlapping corridors in key producing and consuming regions.
TC Energy’s competitive advantage lies in the regulated tariff structure governing its Canadian transmission assets — providing earnings visibility and cash flow stability that underpins the company’s investment grade credit rating and dividend programme — alongside the strategic irreplaceability of infrastructure connecting Western Canadian gas supply to North American and Pacific export markets.
