TransCanada is getting back to the basics: gas transmission and power generation. Through TransCanada PipeLines and other subsidiaries, it wholly owns more than 42,100 miles of natural gas pipeline; its six pipelines link the Western Sedimentary Basin to markets in seven Canadian provinces and 35 US states and Mexico. The company also owns a major oil pipeline (Keystone) and stakes in several other gas pipelines in the US, Canada, and Mexico. TransCanada has 370 billion cu. ft. of natural gas storage assets. On the power side of its business portfolio it owns, operates, or controls about 20 power plants in Canada and the US, with more than 11,800 MW of power generation capacity.
