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 / 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)	$6.86M Shown in table $6.86M (2026 real AUD) Reported / source value $6.50M (2024 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups).

Notes
No plant-specific greenfield capex announcement could be verified from owner/developer/government sources in web search. The site appears to be a publicly announced Hanwha Energy Australia battery project at 260 MW, with Boiling Down BESS Pty Ltd described as an entity supporting modifications to the Gregadoo Solar Farm project site to incorporate a 200 MW battery in Hanwha's FY24 modern slavery statement; however, this does not provide a project cost. O&M and other operating assumptions use the provided internal fallback defaults. Fixed OPEX annual is calculated as 25,000 AUD/MW-yr × 260 MW = 6,500,000 AUD/yr.
