Darling Downs Pipeline

The Darling Downs Pipeline (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

We look forward to discussing your gas transportation requirements.
