The Australian Energy Market Operator (AEMO) has announced that renewables and storage supplied 51% of the Australian electricity needs during the fourth quarter of 2025 (AEMO press release, 29/01/2026). According to the AEMO’s Quarterly Energy Dynamics report, renewable output peaked at 91% on 20 December 2025.
In the fourth quarter of 2025, wind power generation grew by 29%, grid-connected solar by 15% and battery discharge nearly tripled "to an average of 268 MW, supported by 3,796 MW of new battery capacity added since late 2024." The increase of renewables and storage capacity contributed to a fall in coal-fired power generation "to an all-time quarterly low, down 4.6% year-on-year, while gas-fired generation dropped 27% to its lowest level since Q4 2000."
Wholesale electricity prices averaged AUD50MWh (US$35MWh) across the NEM, representing a reduction of 44% compared to the fourth quarter of 2024 and a -43% decline from the third quarter of 2025.
Gas production declined across all regions of Australia, with a quick decline on Queensland LNG export demand that saved 2.3 PJ for the domestic market that helped offset an 8.9 PJ decline in Victorian production.
