Darling Downs Pipeline

Last updated 27 October 2018

The Darling Downs Pipeline (DDP) plays an important part in delivering 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 DDP consists of three interconnected gas transmission pipeline licences in the Darling Downs region in South-East Queensland that operate as a single pipeline network. It links the Wallumbilla gas hub near Roma with the Talinga gas plant near Chinchilla and Origin’s Darling Downs gas fired power station near Dalby in Queensland.

The DDP spans 292km in length and transports gas from the Bowen-Surat basin to the Wallumbilla gas hub, Origin’s 630MW Darling Downs Power Station, and to APLNG’s export pipeline.

Gas transported on the DDP is currently delivered to:

  • Brisbane via the Roma Brisbane Pipeline at Wallumbilla (Run 7)
  • Gladstone via the GLNG Pipeline at Wallumbilla (Santos WCS) or via the APLNG Pipeline at Talinga
  • South West Queensland Pipeline at Wallumbilla (Run 6 and Run 9), for delivery to southern markets
  • Darling Downs Power Station at the eastern end of the DDP

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.

Jemena does not currently have a standard service offering available on the DDP. As a responsible service provider, we are taking time to understand and develop the capabilities of the pipeline to service new users while ensuring a reliable service to existing users. We do, however, encourage prospective new users to contact us to discuss how DDP can play a role in servicing their gas transportation needs.
