What Is The National Electricity Market (NEM)?

The National Electricity Market (NEM) and Western Australia’s South-West Interconnected System (SWIS) are the largest electricity markets in Australia. The NEM covers Australia’s eastern and south-eastern coasts and comprises five states: Queensland, New South Wales (including the Australian Capital Territory), South Australia, Victoria, and Tasmania.

The SWIS covers south-west Western Australia. Together the NEM and the SWIS cover eighty-six per cent and eight percent, respectively, of Australia’s electricity demand.
