“Renewable Energy will comprise at least 50% of the energy in Australia’s National Electricity Market no later than 2030.”

Renewable energy's contribution to total energy in the National Electricity Market passed 10% in 2010 and 20% in 2018. By mid-2020 renewable energy's contribution was just shy of 25%. With a number of coal power stations approaching end of life and with wind and solar generation being the lowest cost forms of new energy available in Australia, large amounts of new renewable generation will be built through the 2020s. (For the purposes of this prediction, energy in the NEM includes energy generated "behind-the-meter" from solar panels, as predicted by AEMO, the energy market operator.)
