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)
$2.03M

Shown in table
$2.03M (2026 real AUD)

Reported / source value
$1.92M (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Scaled the benchmark to the site capacity because the source provides per-MW fixed O&M.

Shown in table
$13.5k (2026 real AUD)

Reported / source value
$12.8k (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Used the 4-hour BESS benchmark value as the closest published AEMO operating-cost assumption.

$0.00 (2026 real AUD)

Reported / source value
$0.00 (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
AEMO table shows no variable O&M for the BESS benchmark.

Notes
No plant-specific greenfield capex announcement was found in the searched owner/developer/government sources. Fallback operating assumptions are based on AEMO 2024 battery benchmark values for a 200 MW BESS; fixed O&M was scaled to the stated 150 MW site capacity. Golden Plains BESS is publicly described as a 150 MW / 600 MWh project planned to commence construction in late 2025.
