Northern Gas Pipeline

The Northern Gas Pipeline (NGP) is a key component of Jemena’s Northern Growth Strategy which seeks to build an interconnected supply chain of energy delivery assets in northern Australia through targeted acquisitions and greenfield developments.

The Northern Gas Pipeline (NGP) is a 622km gas transmission pipeline between Tennant Creek (NT) and Mount Isa (Qld). It is owned and operated by Jemena Northern Gas Pipeline Pty Ltd. The NGP, which links the formerly separate northern and eastern gas markets, started commercial operations in January 2019.  

The main purpose of the NGP is to provide a pathway to transport gas from production facilities in the Northern Territory to demand centres in Mount Isa and eastern Australian states. It is an example of Jemena's continued commitment to providing dependable and competitive gas transportation solutions. 

Jemena is committed to the provision of voluntary, non-discriminatory, pipeline access to third parties. We operate within a framework that takes into account sound commercial principles, and provides a fair and reasonable foundation to meet shippers’ needs.  Jemena believes that such a commitment is essential to the development of transparent and competitive markets for pipeline services.

Local and Indigenous participation have been key considerations for Jemena throughout the planning, construction, commissioning and operation of the NGP.
