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)	— How this was derived Government project record confirms development-stage work and that the project did not proceed further, but does not provide a total build cost.

Capex / MW	$4,912,664 Shown in table $4.91M (2026 real AUD) Reported / source value $4.50M (2023 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups).
Fixed OPEX (annual)	$30.57M Shown in table $30.57M (2026 real AUD) Reported / source value $28.00M (2023 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups). How this was derived Annual fixed O&M was calculated using the benchmark and the project target capacity of 1000 MW from Alinta/ARENA sources.

Notes
No plant-specific greenfield project cost was found in official owner/developer or government sources. The project remains pre-planning and Spinifex/Alinta materials located did not disclose total capex. Fixed O&M is therefore based on AEMO/Aurecon 2024 offshore wind benchmark. Project target capacity has been described as 1000 MW in 2023 Alinta and ARENA sources, and as 1GW+ / 1.2GW in later project pages; no commissioned capacity or online date is available.
