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)	$36.92M Shown in table $36.92M (2026 real AUD) Reported / source value $35.00M (2024 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups). How this was derived Searches did not return an owner/developer/government announcement with a total project cost for this battery.
Capex refurbishment	—
Capex / MWh storage derived	$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)	$2.64M Shown in table $2.64M (2026 real AUD) Reported / source value $2.50M (2024 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups). How this was derived Annual fixed O&M derived from the provided default and stated 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 User-provided server-side fallback default used for battery fixed O&M.
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 User-provided server-side fallback default used for battery variable O&M.

Notes
No project-specific greenfield capital cost announcement was found in web search for Collinsville North Battery Project / TBSOL. Fixed and variable O&M are therefore set from the provided internal battery defaults. Asset life is an indicative battery default, not a project-specific disclosed value.
