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.
  • 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.

Notes
Gladstone Power Station was officially opened in September 1976; the plant’s unit sizes are 280 MW. AEMO/Aurecon 2024 review provides a generic black-coal new entrant heat rate of 8.98 GJ/MWh and availability assumptions for Australian black coal plants; the same review also contains a generic sub-critical boiler O&M example, which is used here only as a fallback proxy because plant-specific O&M was not located. Capex is left null because no plant-specific original construction cost source was found in the searched official and owner sources.
