Power Plants in Australia

Australia has 615 power plants mapped on the OverWatts open energy atlas — the 6th-largest fleet of the 155 countries that hold any, and 2% of the world's mapped total. Of these, 205 operating and 393 under construction or proposed. Operating generation capacity totals 70.1 GW across 205 utility-scale plants of 100 MW and above. The largest is Western Green Energy Hub solar farm (32.0 GW).

The largest owner-operators are AGL Energy Ltd (22), Neoen SA (19) and Origin Energy Ltd (19) — AGL Energy Ltd alone is named on 4% of them. Half of Australia's power plants in service predate 2015 (median commissioning year of the 199 with a known date), 99 came online in the past decade and the oldest still listed is Tungatinah hydroelectric plant, dating from 1953. 393 are in the pipeline, led by Western Green Energy Hub solar farm (32.0 GW), proposed. They account for 46% of every energy asset OverWatts maps in Australia.
