With more than 65 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 10,500 MW of generation capacity powered by natural gas, nuclear, 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, Pennsylvania 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.

TransCanada is one of the continent's largest providers of natural gas storage and related services with approximately 664 billion cubic feet (Bcf) of total gas storage, including 118 Bcf of non-regulated and 546 Bcf of regulated storage capacity.
