With more than 60 years experience, TransCanada is a leader in the responsible development and reliable operation of North American energy infrastructure, including natural gas and oil pipelines, power generation and natural gas storage facilities. TransCanada’s businesses are organized into two segments: Pipelines and Energy. The Pipelines business is principally comprised of TransCanada’s pipelines in Canada, the United States and Mexico..


We own, control or are developing approximately 11,800 MW of generation capacity powered by natural gas, nuclear, coal, hydro, wind and solar assets. Our power business in Canada is mainly located in Alberta, Ontario and Quebec. Our power business in the U.S. is located in New York, New England, and Arizona. The assets are largely supported by long-term contracts and some represent low-cost baseload generation, while others are critically located, essential capacity.

We conduct wholesale and retail electricity marketing and trading throughout North America from our offices in Alberta, Ontario and Massachusetts to actively manage our commodity exposure and provide higher returns.

Non-regulated Gas Storage

TransCanada is one of the continent's largest providers of natural gas storage and related services with approximately 400 billion cubic feet (Bcf) of capacity.

Our non-regulated gas storage business owns or controls more than 150 Bcf, or approximately 40% of all storage capacity in Alberta — through our 50 Bcf Edson and our 68 Bcf Crossfield, Alberta, facilities as well as a long-term, third-party contract.

Our regulated gas storage business, ANR Storage Company, provides firm and interruptible natural gas storage services to customers on our Great Lakes Gas Transmission and ANR Pipeline systems.
