South Australia's big battery fleet achieved a world-leading 40% share of instantaneous demand during the evening peak, delivering a record 611 MW, surpassing California's recent peak. The state leads in wind and solar energy, aiming for 100% net renewables by 2027. The batteries provide grid stability, allow for time shifting of excess renewable energy, and reduce reliance on fossil fuels. The addition of a new transmission link to NSW will further support the state's transition to cleaner energy sources, with synchronous condensers and large batteries ensuring grid stability and steady power feeds for industrial operations. The increasing share of battery discharge and integration of large scale solar-battery hybrids are key steps towards a more renewable energy future.
