Revenue (× MLF)

Estimated $ per interval — energy (RRP) and FCAS (regional FCAS prices), both × MLF.

Methodology & assumptions

  • Dispatch & availability — AEMO Next Day Dispatch UNIT_SOLUTION (5‑minute intervals). Intervention intervals excluded.
  • Regional price — dispatch_price RRP matched by settlement time and NEM region (from generator registry).
  • Energy revenue (× MLF) — cleared MW × (5/60 h) × RRP × MLF.
  • FCAS revenue & volume — cleared FCAS MW from DISPATCHLOAD (raise/lower 6s, 60s, 5min, reg) × (5/60 h) × regional FCAS price × MLF. Volume is total FCAS enablement MWh across services.
  • State of charge — INITIAL_ENERGY_STORAGE (MWh at interval start) from UNIT_SOLUTION, published for bidirectional/storage units. Next-day data — the SOC line lags real time by up to a day.
  • Curtailment — estimated economic curtailment when availability exceeds dispatch target: max(0, availability − cleared) × (5/60) MWh.
  • Not settlement — estimates only. AEMO settlement applies DLF, rebids, constraints, and other factors not modelled here.

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.

Reported / source value
$4,000.00M (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Confirms Stage 2 / West is part of the larger 1,333 MW mega-project, but does not give a West-only AUD cost.

Notes
Reported project cost for the full Golden Plains Wind Farm appears to be about A$4 billion, with sources describing Golden Plains as a 1,333 MW project and Stage 2/West as part of the larger development. West stage construction commenced in mid-2024 and is described as ~574 MW / 577 MW in project materials; the owner/developer sources did not provide a separate West-only capital cost, so the full-project reported cost was allocated to this site as the best available plant-level proxy. O&M values were not plant-specific, so server defaults were used for wind onshore.
