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)	$527.43M Source value $500.00M (2024 nominal) How this was derived Provides context that Iberdrola referenced Broadsound within its Australian investment program, though it does not specifically state BESS-only cost. Reference Iberdrola starts up the world's first wind-solar hybrid plant in Australia (medium confidence)

Notes
No plant-specific battery-only capex announcement was found. The reported A$500m investment appears to cover the full Broadsound Solar Farm and Battery project (solar + BESS), not the battery alone. I therefore allocate the full reported project cost to this generator as a proxy, but this likely overstates BESS-only capex. Registered battery output is 240MW with 360MWh storage; project documents also describe the BESS as 180MW/360MWh. Use with caution.
