Solar and wind cover record 80.4% of Australia's grid demand

Utility solar, wind and hydro provided most of the remaining renewable supply, leaving coal and gas at about 20% during the record period. Some surplus generation was stored in batteries and pumped hydro, while additional output was curtailed because of network constraints, system-security limits and low prices. Renewables averaged 44% of National Electricity Market generation in the year to June, showing the difference between a midday peak and the full-year transition challenge.
