Notes
Project appears to be a 125 MW / 500 MWh four-hour battery. Owner site states estimated investment value of more than $220 million; a separate SA government submission cited approximately $240 million early estimate. Fixed O&M and efficiency are drawn from AEMO/Aurecon battery benchmarks as no project-specific operating data was found. Capex per MWh is based on the inferred 500 MWh storage duration.
