Notes
Plant-specific public source states Junction Rivers is a '$2 billion+' wind energy and storage project; the 200 MW/800 MWh battery is part of the wider project, so capex is allocated proportionally to the battery share using the registered 200 MW / 800 MWh battery size. This is an inferred allocation, not a directly stated battery-only cost. AEMO/Aurecon battery benchmark for a 200 MW / 800 MWh (4-hour) co-located BESS implies about AUD 269.4m EPC and AUD 7,000/MW-year fixed O&M in 2024 terms, but the project-specific reported headline project cost takes precedence for capex under the user's hierarchy.
