South Australia has achieved remarkable new records in renewable energy, with wind energy hitting a new peak share of 149.6% of state demand. The state has been running at an average of 75% wind and solar over the past year and aims to reach 100% "net" renewables by 2027. Battery storage is also playing a significant role in reducing the reliance on fossil fuels, with 31.2% of demand being met by batteries at peak times. The state's increased capacity on interstate transmission lines and new big battery projects under construction are further contributing to the growth of renewable energy. A world-first trial by AEMO using battery inverters to run big grids with no synchronous generation showed promising results, setting records for renewables share, curtailment levels, and battery charging load on Sunday.
