Our Businesses

Our Businesses
TransCanada's businesses are organized into two segments: Pipelines and Energy. 


The Pipelines business is principally comprised of TransCanada's natural gas pipelines in Canada, the United States and Mexico. We are also the general partner of TC PipeLines, LP, a limited partnership that owns interests in U.S. pipelines.

With increasing production from oil sands in Alberta, and growing demand for secure, reliable sources of energy, TransCanada has identified opportunities to develop oil pipeline capacity. The Keystone pipeline complements our natural gas transmission business, draws on our extensive pipelines experience and offers an efficient way to maximize the value of our current pipeline assets.  


The Energy business includes:

Power Generation

  • Encompasses natural gas, nuclear, coal, hydro and wind generation.
  • TransCanada owns, controls or is developing more than 10,800 megawatts of power generation.
  • TransCanada also conducts wholesale and retail electricity marketing and trading in Alberta, Ontario and the northeast U.S.

Non-regulated Gas Storage

  • Owns or controls approximately 130 billion cubic feet of natural gas storage capacity approximately one third of all storage capacity in Alberta.
