Capex / MWh storage
$369,198

Shown in table
$369.2k (2026 real AUD)

Reported / source value
$350.0k (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).
Fixed OPEX (annual)
$2.78M

Shown in table
$2.78M (2026 real AUD)

Reported / source value
$2.64M (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Annual fixed O&M was scaled to the project capacity using the benchmark per-MW figure.

Fixed OPEX / MW-yr
$23,207

Shown in table
$23.2k (2026 real AUD)

Reported / source value
$22.0k (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
For the 1-hour BESS case, AEMO/Aurecon shows fixed O&M of 5,400 and extended warranties of 3,600 per MW-year, totaling 9,000 per MW-year.

$1.58

Shown in table
$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
The benchmark shows no separate variable O&M for BESS; user-supplied default of AUD 1.50/MWh retained in profile because no plant-specific value was found.

Notes
Project-specific greenfield capex could not be located in owner, government, or planning sources. Planning documents identify the project as approximately 120 MW / 480 MWh. Fixed O&M is estimated from AEMO/Aurecon 2024 BESS benchmark of AUD 5,400/MW-year fixed O&M plus AUD 3,600/MW-year extended warranties (total AUD 9,000/MW-year), not a reported plant-specific value; annual fixed O&M shown is scaled to 120 MW. Battery design life benchmarked at 20 years; no fuel/heat-rate assumptions apply.
