Moomba to Adelaide Pipeline System (MAPS), South Australia

EpicEnergy_MAPS 600x900

Epic Energy took ownership of the MAPS in the mid-1990s when it was privatised.

The MAPS is one of Australia's oldest and longest pipelines. It was developed by the Pipelines Authority of South Australia (a Government owned utility) and commenced operation on 28 November 1969, delivering gas from Moomba, in the Cooper Basin, for use in South Australian power generation, industrial and domestic applications. The pipeline was privatised in 1995.

The MAPS supplies gas to regional centres as well as to Adelaide. A pipeline lateral running from the mainline supplies Port Pirie and Whyalla. An additional lateral to Angaston delivers gas to industrial users and into the Riverland Pipeline that, in turn, supplies gas users in Berri, Murray Bridge and Mildura.

In addition to delivering gas from the Cooper Basin into the South Australian market, the MAPS can receive gas from southeast Queensland through the APA-owned 'QSN Link' and from Victoria through the SEA Gas pipeline.


Gas transportation contracts are in place for various contract terms with significant business partners in the electricity generation, gas distribution and industrial sectors. End users of gas include Origin Energy, AGL, Engie, Liberty OneSteel and Adelaide Brighton Cement.
