Gas Transmission Northwest
From Wikipedia, the free encyclopedia
Gas Transmission Northwest is a natural gas pipeline that brings gas from western Canada through Washington and Oregon into California, connecting to the Pacific Gas and Electric system. Prior to being purchased by TransCanada Corporation, it was named Pacific Gas Transmission. Its FERC code is 86.[1]
[edit] System overview
The 612 mile long GTN system interconnects with TransCanada's BC System at Kingsgate, British Columbia; with Williams (Northwest Pipeline Corporation) at Spokane and Palouse, Wash., and at Stanfield, Ore.; and with Pacific Gas & Electric Company and Tuscarora Gas Transmission Company at Malin, Ore. Multiple taps also connect the GTN System to Avista Corporation and Cascade Natural Gas.
The gas in the pipeline is primarily from Western Canada, but the GTN System also receives U.S. domestic gas supplies at Stanfield, Ore.
The GTN System can transport more than 2.9 billion cubic feet of gas a day (Bcf/d). More than 2.1 Bcf/d can be delivered to California, and up to 1 Bcf/d to the Pacific Northwest (though typical deliveries there are 600-700 million cubic feet a day).
GTN began service on December 2, 1961. The GTN System was the first fully automated natural gas pipeline in the U.S.
