Fresh doubts have been raised about the viability of the federal government's proposed Kurri Kurri gas peaking plant following the release of new data showing demand for gas is declining.
National Electricity Market data shows gas generation fell in every state in Australia between the first half of 2021.
Renewable energy sources - including wind, solar, hydroelectricity and biomass - supplied 28.8 per cent of electricity in Australia's main grid. Gas supplied just 6.1 per cent of electricity generation.
The government is pushing ahead with the $600 million 1000 megawatt gas-fired peaker at Kurri on the basis that it will be needed to provide stability to the grid following the closure of Liddell power station in 2023
