Notes
Project-specific capital investment value of $518 million found in NSW Department of Planning assessment report for the Calala Battery Energy Storage System (SSD-52786213). The report describes a 300 MW / 600 MWh project; Equis later announced a 250 MW / 500 MWh Calala BESS reaching financial close in March 2025. Because the user requested CABESS1 and the project appears to have been resized, capex per MW and per MWh are calculated using the 300 MW / 600 MWh planning value to match the NEM site reference, but this should be reviewed against the registered DUID capacity once available. O&M and performance defaults were not plant-specific in the sources searched, so no plant-specific O&M assumptions were populated.
