Phased Gas Pipeline Network is a proposed natural gas pipeline network in South Africa.[1][2][3]

Location

The network would run throughout South Africa's Strategic Gas Pipeline Corridors, as identified in South Africa's Government Notice 143, published in February 2021.[4]

Background

The South African government laid out the following Strategic Gas Pipeline Corridors in 9 phases:[4]

  • Phase 1a: Saldanha to Ankerlig
  • Phase 1b: Saldanha to Mossel Bay
  • Phase 2: Mossel Bay to Coega
  • Phase 3: Richards Bay to Gauteng
  • Phase 4: Mozambique (Southern Border) to Richards Bay
  • Phase 5: Abraham Villiers Bay (Northern Cape) to Saldanha
  • Phase 6: Abraham Villiers Bay (Northern Cape) to Oranjemund
  • Phase 7: Coega to Richards Bay
  • Phase 8: Rompco Pipeline Corridor
  • Phase 9: Inland Corridor from Saldanha to Coega

The image above shows the pipeline corridors that are intended to encompass the proposed pipeline routes.[4]

  • Capacity:
  • Length:
  • Status: Proposed
  • Start year:


Location

The Saldanha Bay–Ankerlig Gas Pipeline is Phase 1A of South Africa's Phased Gas Pipeline Network. It would carry gas from the proposed Saldanha Bay LNG Terminal to the Ankerlig Power Station near Cape Town.[1][2]

The pipeline would run from the proposed Saldanha Bay LNG Terminal in Saldanha Bay to the Ankerlig Power Station near Cape Town, in Western Cape province, South Africa.

Location

The Saldanha–Mossel Bay Gas Pipeline is Phase 1B of South Africa's Phased Gas Pipeline Network (PGPN). It would carry gas from the proposed Saldanha Bay LNG Terminal to the terminal at Mossel Bay. In addition to the proposed LNG terminal, it would also connect with the existing Mossel Bay F-A offshore gas platform, and with the proposed iBhubesi offshore gas platform.[1][2]

The pipeline would run from the proposed Saldanha Bay LNG Terminal in Saldanha Bay to the terminal at Mossel Bay, in Western Cape province, South Africa.

Location

The Mossel Bay–Coega Gas Pipeline is Phase 2 of South Africa's Phased Gas Pipeline Network (PGPN). It would carry gas from the terminal at Mossel Bay to the port of Coega (and presumably to the new gas-fired Dedisa Power Station at Coega).[1][2]

The pipeline would run from the terminal in Mossel Bay, Western Cape province, to the port of Coega, near Port Elizabeth, Eastern Cape province, South Africa.

Richards Bay–Gauteng Gas Pipeline

  • Operator: Transnet Pipelines
  • Owner: Transnet
  • Parent company: Department of Public Enterprises
  • Capacity:
  • Length:
  • Status: Proposed
  • Start year:


Location

The Richards Bay–Gauteng Gas Pipeline is Phase 3 of South Africa's Phased Gas Pipeline Network (PGPN). It would supplement the Secunda–Durban Lilly Gas Pipeline, which also runs from Richards Bay to Secunda, but has limited capacity. It would start at Richards Bay, connecting to potential offshore gas wells by Eni, which as of Nov. 2019 were in advanced permitting. It would run to Secunda, the endpoint of the Mozambique–South Africa Gas Pipeline. It would then possibly extend to the west, either to southern Gauteng or to Sasolburg, in Free State.[1][2]

The pipeline would run from the port at Richards Bay, KwaZulu-Natal province, to Secunda, Mpumalanga province, and possibly on to Sasolburg, Free State, and/or to southern Gauteng province, South Africa.

Mozambique–Richards Bay Gas Pipeline

  • Operator: Transnet Pipelines
  • Owner: Transnet
  • Parent company: Department of Public Enterprises
  • Capacity:
  • Length:
  • Status: Proposed
  • Start year:


The Mozambique–Richards Bay Gas Pipeline is Phase 4 of South Africa's Phased Gas Pipeline Network (PGPN)[4], though in the original environmental assessment, it was not seen as part of the program because it didn't allow for offshore gas exploration in South Africa.[1] This segment is considered part of the 2600-kilometer proposed GasNosu North–South Gas Pipeline and would likely connect Maputo, Mozambique with Richards Bay.

Location

The pipeline would run from the Mozambique border to Richards Bay.[1][2]

Abraham Villiers Bay–Saldanha Gas Pipeline

  • Length:
  • Status: Proposed
  • Start year:


Location'

The Abraham Villiers Bay–Saldanha Gas Pipeline is Phase 5 of South Africa's Phased Gas Pipeline Network (PGPN). Gas has already been discovered at the iBhubesi offshore gas field, off the coast from Abraham Villiers Bay; the South African Gas Development Company (iGas) believes that there are additional gas fields off the coast in this area. iGas completed route engineering for an onshore pipeline from Villiers Bay to Saldanha prior to 2014. At Saldanha Bay, the pipeline would connect to the proposed Saldanha Bay LNG Terminal, as well as to Phases 1A and 1B of the PGPN, Saldanha–Ankerlig Gas Pipeline and Saldanha–Mossel Bay Gas Pipeline.[1][2]

The pipeline would run from the Abraham Villiers Bay, Northern Cape, to the proposed Saldanha Bay LNG Terminal in Saldanha Bay, Western Cape, South Africa.

Abraham Villiers Bay–Oranjemund

  • Operator: Transnet Pipelines
  • Owner: Transnet
  • Parent company: Department of Public Enterprises
  • Capacity:
  • Length:
  • Status: Proposed
  • Start year:


Location

The Abraham Villiers Bay–Oranjemund Gas Pipeline is Phase 6 of South Africa's Phased Gas Pipeline Network (PGPN). It would carry gas from Oranjemund, Namibia, and would connect with Phase 5 of the PGPN, the Abraham Villiers Bay–Saldanha Gas Pipeline, at Abraham Villiers Bay, Northern Cape, South Africa.

This pipeline could potentially run in either direction. Namibia's state-owned gas firm NAMCOR plans to develop the Kudu offshore gas field, off the coast of Oranjemund, and to use the gas to power a new gas-fired power plant, the proposed Kudu Power Station at Oranjemund. If the project to build the Kudu Power Station does not go ahead, South Africa could import the gas from the Kudu offshore field. However, if the Kudu Power Station is built, South Africa estimates that the Kudu field only has enough gas to power the plant for about 20 years; after the Kudu field is depleted, South Africa could export gas through the pipeline to continue powering the Kudu Power Station.[1][2]

The pipeline would run from Oranjemund, ǁKaras, Namibia to Abraham Villiers Bay, Northern Cape, South Africa.

Coega–Richards Bay Gas Pipeline

  • Operator: Transnet Pipelines
  • Owner: Transnet
  • Parent company: Department of Public Enterprises
  • Capacity:
  • Length:
  • Status: Proposed
  • Start year:


Location

The Coega–Richards Bay Gas Pipeline is Phase 7 of South Africa's Phased Gas Pipeline Network (PGPN). It would connect with Phase 2 of the PGPN, the Mossel Bay–Coega Gas Pipeline, at Coega, and with Phase 3 of the PGPN, the PGPN Richards Bay–Gauteng Gas Pipeline, at Richards Bay. The PGPN's sponsors consider this to be "an expensive and unlikely scenario due to the significant length of the pipeline and the absence of substantial markets (except domestic use) between the two ends." However, it would allow the western and eastern portions of the PGPN to be linked into a single network.[1][2]

The pipeline would run from Coega port, Eastern Cape, to Richards Bay, KwaZulu-Natal, South Africa.

Rompco Gas Pipeline

  • Capacity:
  • Length:
  • Status: Proposed
  • Start year:


Location The Rompco Gas Pipeline is Phase 8 of South Africa's Phased Gas Pipeline Network (PGPN). It would connect Mozambique with Phase 3 of the pipeline.[1][2] While South Africa's plans for the project are unclear, it appears that this would be similar to the Mozambique–South Africa Gas Pipeline, owned and operated by Rompco.[5]

  • Capacity:
  • Length:
  • Status: Proposed
  • Start year:


Location The Saldanha–Coega Inland Corridor Gas Pipeline is Phase 9 of South Africa's Phased Gas Pipeline Network (PGPN). It would run from Saldanha to Coega, tracing a route further inland away from the coast.[1][2][4]
