Electricity sector in Australia

The Australian electricity sector has been historically dominated by coal-fired power stations, but renewables are forming a rapidly growing fraction of supply.

Due to its large size and the location of its population, Australia lacks a single grid that covers all states, but has a transmission grid that extends along the east coast from Queensland via New South Wales and Victoria to South Australia and also connects via submarine DC cable with Tasmania.

Since 2005, wind power and rooftop solar have led to a fast growing share of renewable energy in total electricity generation. Generation from renewable sources reached a share of 32.5 per cent in 2021, an increase from 16.9 per cent in 2017.
