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.

How this was derived
Indicates a black coal heat-rate assumption around 10 GJ/MWh in GenCost 2024-25; user-provided fallback heat rate retained due to lack of plant-specific data.

Notes
Gladstone Power Station is Queensland’s largest coal station with six 280 MW units (1,680 MW total). No verified greenfield capex figure was located; therefore capex fields remain unset. If a refurbishment or life-extension figure becomes available, it should be recorded separately as capex_refurbishment_aud rather than greenfield capex.
