Notes
No plant-specific greenfield capex announcement or owner-reported total project cost was found in the searched sources. The project is operational at 155 MW / 298 MWh and is operated by Akaysha Energy, while the registered owner is Ulinda Park ProjectCo Pty Ltd. GenCost 2024-25 confirms large-scale battery costs fell 20% year-on-year, but the report excerpt accessible here did not expose a usable plant-specific capex benchmark, so capex fields remain unset rather than inferred from benchmark assumptions.
