The Moomba to Sydney Pipeline (MSP) is a transmission pipeline that operates across NSW. The pipeline is owned and operated by the APA Group.
The pipeline is 2 081 km in length and has a forward haul capacity of 489 TJ/day and a back haul capacity of 120 TJ/day. The pipeline links the Cooper basin gas fields at Moomba in South Australia to gas distribution systems in Sydney, Newcastle, Wollongong, Canberra and some NSW regional centres.
Since 2008, with the completion of the QSN Link which connects to the MSP at Moomba and the change in flow direction on the South West Queensland Pipeline (SWQP), gas can also be sourced from conventional and coal seam gas fields in the Bowen-Surat basin in Queensland. In December 2015, the MSP became bi-directional. A new receipt point at Wilton connected to Jemena Gas Networks’ Eastern Gas Pipeline and the provided the ability to flow gas north to Moomba.
The Moomba to Marsden portion of the MSP is currently treated as 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 pipeline was initially subject to regulation by the ACCC as a covered pipeline under the Gas Code. The coverage of the Moomba to Marsden segment of the MSP was revoked in November 2003. The remainder of the covered pipeline, from Marsden to Wilton (and laterals), has been subject to light regulation under the NGR since November 2008.
The MSP was constructed in 1976 to service the NSW gas market. It comprises a mainline from the Moomba processing plant to Wilton near Sydney and four lateral pipelines (Young to Orange and Lithgow, Young to Wagga Wagga, Junee to Griffith and Dalton to Canberra). With the completion of the NSW-Victoria Interconnect between Wagga Wagga and Culcairn in 1998, gas can be transported bi-directionally between NSW and the Victorian Transmission System. The capacity between NSW and the Victorian Transmission System has been progressively expanded between 2014 and 2017 to transport additional gas between NSW and Victoria. The MSP is also interconnected with the Central West Pipeline (CWP) and the Central Ranges Pipeline (CRP).
