Financial overview

2026 real AUD. Monetary values are CPI-adjusted to 2026 real Australian dollars. Greenfield capex uses AEMO benchmarks when plant-specific cost is unknown.

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 No authoritative plant-specific greenfield capex figure was located in ACEN Australia, EPBC, or other official sources during the search.
Capex refurbishment	—
Capex / MWh storage	—
Fixed OPEX (annual)	$2.11M Shown in table $2.11M (2026 real AUD) Reported / source value $2.00M (2024 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups). How this was derived Derived from the provided fallback O&M assumption and the stated 80 MW capacity.
Fixed OPEX / MW-yr	$26,371 Shown in table $26.4k (2026 real AUD) Reported / source value $25.0k (2024 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups). How this was derived This was supplied as an internal technology default by the user and used only because no project-specific O&M figure was found.
Variable OPEX / MWh	$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 This was supplied as an internal technology default by the user and used because no project-specific variable O&M figure was found.

Notes
No plant-specific greenfield construction cost was found in official ACEN or government sources. ACEN describes the project as a proposed 80 MW battery co-located with a 100 MW solar project (180 MW / 2-hour BESS in later ACEN project pages), but publicly available materials did not disclose total project capex. Default battery O&M and capex assumptions were therefore used from the provided server-side fallback only for capex_per_mw_aud and O&M values, not as reported project cost. Fixed OPEX annual value is derived from 25,000 AUD/MW-yr × 80 MW.
