This article is part of the Global Fossil Infrastructure Tracker, a project of Global Energy Monitor.

The Eastern Gas Pipeline is an operating natural gas pipeline.[1]


The pipeline runs from Longford, Victoria, to Sydney, New South Wales.[2][3]

Project Details

  • Operator: Jemena[4]
  • Owner: Jemena[4]
  • Parent company: SGSP (State Grid Corporation of China 60%; Singapore Power 40%)
  • Capacity: 355.5 terajoules per day / 336.95 million cubic feet per day[5]
  • Length: 797 kilometers / 495 miles (or 822.42 km including laterals)[6]

The Eastern Gas Pipeline (EGP) is operated and owned by Jemena, which is owned by SGSP (Australia) Assets Pty Ltd.[7] SGSP is jointly owned by State Grid Corporation of China (60%) and Singapore Power (40%).[7]

The EGP is 797 km long, and it connects Longford, in Victoria, to Horsley Park in New South Wales.[6] The EGP includes the main line and around 25 km of lateral pipelines.[6] The pipeline segments included in the Eastern Gas Pipeline are listed in the table below (adapted from the Australian Energy Market Commission's website on the Eastern Gas Pipeline).[6]

Expansion projects

Sydney to Hunter Valley extension

In September 2020, Jemena announced plans to extend the EGP by approximately 185 kilometers from Sydney to the Hunter Valley, with the intention of connecting the valley to existing domestic gas fields as well as to two proposed LNG import terminals, Port Kembla FSRU and the Newcastle LNG Terminal. Jemena said that it expected to take a final investment decision on the AU$400 million expansion project by the end of 2021, with first gas to flow as early as 2023. The company had been working on pipeline route options in the Hunter Valley and said it was preparing to commence community and stakeholder engagement.[8]

The expansion would run from Sydney, New South Wales north to the Hunter Valley, ultimately supplying gas to a gas-fired generator north of Tomago, New South Wales, and to a proposed plant at Kurri Kurri, New South Wales, in the Hunter Valley.[9]

This expansion project was mentioned in the 2021 Australian National Gas Infrastructure Plan, as part of necessary infrastructure for unlocking Gunnedah Basin gas resources.[10]

As of August 2023, no new updates regarding the Sydney to Hunter Valley extension have been found since 2021, so the project is considered to be shelved.

Port Kembla Lateral Looping Pipeline

In 2020, Jemena submitted a request to modify the Eastern Gas Pipeline to "allow it to increase the capacity of the Port Kembla lateral by constructing and operating a second pipeline (the Port Kembla Lateral Looping Pipeline) that would generally follow the same alignment as the existing Port Kembla lateral (i.e. to duplicate the Port Kembla lateral)."[12]

Jemena's expansion request followed the approval that was granted to Australian Industrial Energy (AIE) to construct and operate the Port Kembla LNG Terminal.[12] The terminal is planned to receive LNG, re-gasify it, and transport it via its own pipeline segment (part of AIE's LNG terminal project) to the Port Kembla lateral pipeline for subsequent distribution to New South Wales via the Eastern Gas Pipeline.[12]

However, because the existing Port Kembla lateral has a capacity of only 32 petajoules per year, the pipeline requires an expansion to increase its capacity to meet the terminal's gas output, which is expected to be up to 115 petajoules per year.[12] According to the Modification Assessment Report published by the New South Wales government for the looping pipeline project, "if approved, the pipeline would facilitate the operation of Port Kembla Gas Terminal project at full capacity and increase the supply of gas to the New South Wales market."[12]

As part of the project, Jemena has also proposed modifying the Eastern Gas Pipeline to allow gas to flow to Victoria (i.e., reversing the current flow of gas).[13]

The Port Kembla Pipeline Project involves the construction of both the Port Kembla Lateral Looping Pipeline[14] and AIE's pipeline segment, which is part of the company's infrastructure approval plans for the Port Kembla LNG Terminal.[15][16] Both segments will be operated and built by Jemena, but the segment that directly ties into the Port Kembla LNG terminal will be owned by AIE.[14][15]
