Notes
Project-specific owner website describes Junction Rivers as a '$2 billion+ wind energy and storage project'. Site materials also describe the project as 600 MW wind plus 200 MW/800 MWh battery. Because the DUID name suggests a battery unit but the only project-level reported capex found is for the combined wind-and-storage project, capex_total_aud is assigned to the whole project and per-MW/per-MWh figures are calculated against the 200 MW/800 MWh battery share for this DUID. Fixed O&M was derived from the AEMO/Aurecon 2024 BESS benchmark of $1.6m/yr for a 200 MW 4-hour system, scaled linearly to 200 MW. Variable O&M uses the fallback default. No plant-specific refurbishment cost or battery replacement announcement was found.
