$1,229.51M (2026 real AUD)

Reported / source value
$1,200.00M (2025 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Useful financing context, but not usable as plant capex.

Notes
No plant-specific greenfield capex figure was found in owner, government, or project-finance sources. FRV/ARENA materials confirm a 250 MW / 500 MWh project and financial close, but do not state total project cost. In the absence of a reported project cost, battery capex was not back-filled with an AEMO benchmark. O&M and performance assumptions use AEMO GenCost / cost-parameter review battery defaults for a 200 MW Li-ion BESS scaled to 250 MW, with 20-year life and 84% round-trip efficiency. Variable O&M is treated as zero for large-scale BESS long-term service agreements in AEMO's review.
