|Darling Downs Pipeline Description||Pipeline description|
The Darling Downs Pipeline (DDP), also known as the Darling Downs Gas Pipeline or the Wallumbilla to Darling Downs Pipeline, is a transmission pipeline located in south-east Queensland. The pipeline is owned and operated by Jemena Gas Networks.
The DDP is 292 km in length, and has a diameter of 450 mm. The pipeline has a forward haul capacity of 270 TJ/day and a back haul capacity of 530 TJ/day.
The DDP links the Wallumbilla gas hub near Roma with the Talinga gas plant near Chinchilla and Jemena Gas Networks’ Darling Downs gas fired power station near Dalby in Queensland. Gas is sourced from the Talinga coal seam gas fields in the Bowen-Surat basin which are owned by Australia Pacific LNG.
The DDP is currently a non-scheme pipeline, and is subject to the access regime for non-scheme pipelines under Chapter 6A of the NGL and Part 23 of the NGR.
The DDP was constructed in 2009 and was initially owned and operated by Origin Energy. Origin sold the pipeline to Jemena Gas Networks in 2017.
