Reported / source value
$18.0k (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
No directly extractable AEMO line for solar PV fixed O&M was retrieved in the search session, so the internal fallback value is retained as an unverified placeholder.
Variable OPEX / MWh
$0.21

Shown in table
$0.21 (2026 real AUD)

Reported / source value
$0.20 (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
No plant-specific variable O&M was found; this remains a server-side fallback.

Notes
No plant-specific greenfield capex announcement or official project cost could be located in searched sources. AEMO/CSIRO benchmark sources were located for utility-scale solar PV and BESS assumptions, but no verified Bonnie Brae Hybrid Plant investment figure was found. Given the site is a hybrid battery + solar project, the provided normalised type is solar_fixed only as a fallback label; financial assumptions should be reviewed if project-specific documentation becomes available.
