Natural Gas

Our 67,300 kilometre (41,900 mile) network of natural gas pipelines supplies 20 per cent of the natural gas consumed daily across North America to heat homes, run industries and generate power. This pipeline network strategically connects growing supply to key markets across our three operating geographies of Canada, the U.S. and MexicoOur natural gas pipeline network transports natural gas to local distribution companies, power generation facilities and other businesses across Canada, the U.S. and Mexico.

We serve this natural gas demand on a daily basis by connecting major natural gas supply basins and markets through:

  • Wholly-owned natural gas pipelines – 56,600 km (35,200 miles)
  • Partially-owned natural gas pipelines – 10,700 km (6,700 miles)

Natural Gas Storage

TransCanada owns and operates 368 billion cubic feet of natural gas storage capacity. We have regulated natural gas storage facilities in Michigan with a total capacity of 250 Bcf, making us one of the largest providers of natural gas storage and related services in North America.


TransCanada has identified a unique opportunity to link the growing supply of Canadian crude oil with North America’s increasing demands for energy. Transporting crude oil represents an ideal fit with TransCanada’s existing business strategy – and an efficient way to maximize the value of our current pipeline assets.
