Northern Gas Pipeline

The Northern Gas Pipeline is a gas transmission pipeline in Australia. It runs 622 km from Tennant Creek in the Northern Territory to Mount Isa in Queensland. It took 18 months to construct, and was completed in December 2018.

The Northern Territory already had production facilities offshore, feeding to processing near Darwin, and the bi-directional Amadeus Gas Pipeline running north–south through the Territory connecting to the Amadeus Basin southwest of Alice Springs.

North East Gas Interconnector
The Northern Gas Pipeline addresses a requirement known as the North East Gas Interconnector (NEGI) before it was built. The purpose of the NEGI is to provide a way to transport gas from Northern Territory production to eastern Australian consumers. Options for the NEGI included the Tennant Creek to Mount Isa route that has been built and an alternate course that would have connected from Alice Springs to Moomba in South Australia. There were four proponents invited to bid for the project, with two preferring each route. The successful tender was from Jemena to build and operate the pipeline, to link Tennant Creek to Mount Isa.
