Gas Transmission Northwest System

The Gas Transmission Northwest (GTN) System is strategically positioned to serve western North America - bringing resources from the Western Canada Sedimentary Basin to markets in California, Nevada and the Pacific Northwest.

Connecting to the Foothills System at the British Columbia-Idaho border, GTN is 2,174 kilometres (1,351 miles) in length and connects with the Tuscarora pipeline and with Pacific Gas & Electric at the Oregon-California border.

Major interconnects on the GTN System help serve markets on the Pacific coast and the Southwest.

The GTN System is part of TransCanada's network 57,000 km (35,500 mi.) of wholly owned and 11,500 km (7,000 mi.) of partially owned natural gas pipelines connecting major supply basins with major markets all across North America. TransCanada is one of the continent's largest providers of gas storage and related services with approximately 380 Bcf of storage capacity - that's the second largest in North America. In total, TransCanada delivers approximately 20 per cent of the natural gas consumed in North America each day.

TransCanada operates Gas Transmission Northwest and effectively owns 83.3 per cent of the system through its direct ownership interest and its 33.3 per cent interest in TC PipeLines, LP.
