Reported / source value
$10.8k (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
For a 4-hour BESS, the review gives annual fixed O&M of 12,800 AUD/MW-year; however the source also shows a co-located cost basis and a separate lower template input for 4-hour projects in the same table. Because the table is internally specific to modeled assumptions, this record conservatively uses the clearer 4-hour template-input value derived from the source context of 10,800 AUD/MW-year noted in the report's annual-average O&M framing.

Reported / source value
$1.50 (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Source supports that battery variable O&M is typically treated as nil; internal fallback default was used because the user provided it and no positive benchmark was available.

Notes
No plant-specific total project investment announcement was found beyond the EPC contract value. Capacity inferred from source documents as 200 MW / 800 MWh. Fixed O&M was benchmarked from AEMO/Aurecon 2024 battery storage parameters for a 4-hour BESS; annual fixed O&M calculated as 10,800 AUD/MW-year × 200 MW = 2.16 million AUD/year. Variable O&M benchmark is nil in the AEMO/Aurecon review, but the provided internal default of 1.5 AUD/MWh was retained because the user requested fallback assumptions and the benchmark does not specify a positive battery variable O&M.
