Distribution and storage
There are reticulated eight gas supply areas in Western Australia. These are set out in the Energy Coordination Act 1994. The supply areas are:
- Great Southern
You can view these on the WA Gas Supply Area Map. The Public Utilities Office advises the Governor on changes to supply areas.
The Economic Regulation Authority (ERA) licenses gas distribution systems that operate at a pressure of less than 1.9 megapascals within these gas supply areas. A list of licensed gas distributors is available on the ERA website.
The ERA is also responsible for regulating third party access to regulated or ‘covered’ gas distribution systems in WA, in accordance with the National Gas Law Further information on access arrangements for gas pipelines are available from the ERA website, including a list of covered distribution systems.
There is currently one gas storage facility servicing the domestic gas market. The Mondarra gas storage facility is located near Dongara on the Parmelia Gas Pipeline – see the Energy Resources and Infrastructure Map.
Facility expansion should be completed in 2013, increasing the storage capacity more than five times to 15 petajoules.
