Capex total (greenfield)
$33.76M

Shown in table
$33.76M (2026 real AUD)

Reported / source value
$32.00M (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
ACEN indicates significant construction investment but does not disclose a project-specific total capex figure.

Reported / source value
$12.0k (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Used 2-hour co-located BESS row to infer a mid-point annual fixed O&M rate of about $12,000/MW-year.

$1.58 (2026 real AUD)

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

How this was derived
Used as evidence that variable O&M is effectively nil for the benchmarked BESS.

Notes
No plant-specific greenfield capex figure was found in ACEN/public government sources for Cooma; ACEN describes the project as a proposed 80MW renewable energy generation project with a 180MW/2hr BESS, and NSW planning confirms a 100MW solar farm plus up to 80MW/320MWh BESS. In the absence of a project-specific investment announcement, battery capex was not estimated from benchmarks per instruction; O&M and performance defaults were taken from AEMO/Aurecon 2024 battery assumptions.
