Investing in essential infrastructure — for today and tomorrow

We invest in long-life, critical energy infrastructure that provides reliable delivery of clean-burning natural gas. Natural gas infrastructure is deeply interwoven into the U.S. economy – our industry touches nearly every other industry and our success supports the success of many businesses, big and small. Natural gas and its associated infrastructure also complement renewables, and therefore are key to achieving national and global environmental aspirations.


Natural gas is a major component of the power behind the plug that makes everything turn on, from appliances and electronics in homes, to hospital equipment in our cities, to information and telecommunications systems that connect the globe.”

- Nathan Brown
President, TC PipeLines, LP


Providing safe and reliable service to customers

Our customers span the energy value chain and include large utilities, local distribution companies, major natural gas marketers and producers. These customers, and the markets they serve, depend on us to provide safe and reliable energy to their homes and workplaces.

We operate across the U.S., with the ability to deliver energy into several major markets, including the Pacific Northwest, Northeast U.S. and Midwest and have a strong market position in those regions.

In high demand

Natural gas demand continues to increase as electrical generation, industrial sectors and residential users seek increased use of cleaner-burning natural gas for their power, heating and cooling needs. Recent technological advances have made natural gas abundant, enabling the U.S. to become one of the world’s largest natural gas exporters. North American natural gas production is expected to grow between now and 2040 to meet these needs, providing opportunities for the responsible growth of our infrastructure systems.

A master limited partnership

TC PipeLines, LP is a Delaware master limited partnership. TC PipeLines, LP was formed by TransCanada PipeLines Limited, a wholly owned subsidiary of TC Energy Corporation (TC Energy), to acquire, own and actively participate in the management of United States-based natural gas pipelines and related assets. Our common units trade on the New York Stock Exchange (NYSE) under the symbol TCP.

We are managed by our general partner, TC PipeLines GP, Inc. (TC PipeLines GP), which is indirectly wholly owned by TC Energy, one of the largest energy infrastructure companies in North America. TC Energy subsidiaries also operate our natural gas pipeline systems, apart from Iroquois’ assets and PNGTS’ joint facilities, which are partially owned by third parties and operated by separate management.
