Natural Gas

TransCanada operates one of the most sophisticated pipeline systems in the world. Our network of approximately 57,000 km (35,500 mi.) of wholly owned and 11,500 km (7,000 mi.) of partially owned natural gas pipelines connect virtually every major natural gas supply basin and market, transporting 20 per cent of the natural gas consumed in North America.

TransCanada moves 15 billion cubic feet (Bcf) of natural gas per day, delivering to local distribution companies and businesses across Canada and the U.S. We're continually exploring new ways to help producers reach their markets. This includes transporting crude oil on both existing and new pipelines to connect Canada's growing oil sands supply with refineries in the U.S. Midwest.

Through our wholly owned subsidiary, ANR, TransCanada is also one of the largest developers of new storage facilities and providers of underground natural gas storage services in the U.S. We have nearly 64 Bcf  of storage, and can provide peak-day withdrawal capability of over 0.8 billion cubic feet per day. These services are available to key markets throughout the eastern United States.

Natural Gas Storage

TransCanada is one of the continent's largest providers of natural gas storage and related services. We offer more than 400 Bcf of natural gas storage capacity. This includes approximately 250 Bcf of regulated storage capacity operated by ANR and 130 Bcf of non-regulated storage capacity.


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.
