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)	$1,033.76M Shown in table $1,033.76M (2026 real AUD) Reported / source value $980.00M (2024 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups).

Notes
ACEN’s Deeargee/Deargee project is publicly described as a proposed 320 MW solar and battery project, with battery storage up to 1,400 MW AC two-hour or 700 MW AC four-hour configuration. I could not find a plant-specific greenfield capital cost announcement from ACEN, government, or project finance sources in the available search results, so no capex value is reported. For battery assumptions, I used AEMO/Aurecon 2024 BESS benchmark technical parameters: 4-hour BESS EPC cost $324.1M for a 200 MW system, indicative round-trip efficiency ~85%, and 20-year design life; however, these are not treated as project-reported capex. Variable O&M uses the provided default fallback because the AEMO BESS benchmark excerpt available did not expose a comparable variable O&M figure.
