Western Australia, for example, already has an operational DC-coupled hybrid site in the form of Green Power Generation’s 128MW Cunderdin hybrid solar PV and BESS project, which was inaugurated in early April 2025. The battery component features approximately 10-hour duration capability, positioning it among Australia’s longest-duration grid-scale battery systems currently under construction. Adam Pegg, country manager for Lightsource bp Australia and New Zealand, emphasised that the project demonstrates how long-duration energy storage (LDES) can firm solar generation, enabling coal plants to retire on or before schedule. The hybrid project received federal backing through the Australian government’s Capacity Investment Scheme (CIS). Specifically, the project received backing in the first tender round, which saw solar PV awarded 2.8GW.
