  • Owner: TC Energy[1]
  • Capacity: 2900 million cubic feet per day[1]

Gas Transmission Northwest (GTN) is a 1,353 mile-long natural gas pipeline built in 1961 with a capacity of 2,900 million cubic feet per day.[1] It brings gas from Alberta, Canada, beginning at Kingsgate, British Columbia and passing through Washington and terminates at Malin, Oregon then connecting to California, connecting to the Pacific Gas and Electric system.[1]

Prior to being purchased in 2004 by TC Energy (formerly known as TransCanada Corporation), the pipeline was named Pacific Gas Transmission.[2] TC Energy subsequently sold 25 percent of its interest in GTN to TC PipeLines, LP, which connects via the Tuscarora Gas Pipeline.[2] GTN's FERC code is 86.[2]

Expansion Projects

GTN XPress Expansion Project

In November 2019 TC Energy proposed expanding the pipeline's capacity by 250 million cubic feet per day, with a completion date of 2023.[3] The project will increase imports into Canada via Kingsgate, Idaho, USA.[4]
