through Washington and Oregon
into California
, connecting to the Pacific Gas and Electric system. Prior to being purchased by TransCanada Corporation in 2004, it was named Pacific Gas Transmission. TransCanada subsequently sold 25 percent of its interest in GTN to TC PipeLines, LP, a master limited partnership. GTN's FERC

; with Williams (Northwest Pipeline
) at Spokane
and Palouse, Washington
, and at Stanfield, Oregon
; and with Pacific Gas & Electric Company and Tuscarora Gas Transmission Company
at Malin, Oregon
. 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.
The GTN System can transport more than 2.9 Gcuft/d of gas a day. More than 2.1 Gcuft/d can be delivered to California, and up to 1 Gcuft/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.
