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
No plant-specific greenfield capex announcement for GSTONE4/Gladstone Power Station was found in the searched official and quasi-official sources. AEMO sources confirm the unit is part of the NEM generation information system, but the retrieved pages did not provide project cost, O&M, heat rate, fuel price, or emissions parameters for this specific unit. Because the user required source-backed research and the prompt forbids substituting benchmark capex when a plant-specific figure is not found, capex remains unset. AEMO 2024 technology-cost material was located for fallback benchmarking only, but not applied here because the instruction prioritises plant-specific reporting and the exact benchmark values for black coal subcritical were not extracted from the retrieved passages.
