Notes
Project is 225 MW / 450 MWh and scheduled for completion in 2026 per project website; reported investment figure of A$150 million appears to come from early development/approval-stage disclosures rather than a final financial-close announcement. No project-specific operating-cost disclosure found, so O&M uses AEMO 2024 battery storage benchmark for 2-hour LFP BESS as a fallback. Capacity inferred from project sources.
