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
Callide B was commissioned in 1988 and is 100% owned by CS Energy. No plant-specific greenfield capex figure was found in official owner/government sources in the searched results, so capex remains unset rather than inferred from technology benchmarks. AEMO benchmark O&M for black coal super-critical large plant was used as the closest available official proxy for operating costs; however Callide B is sub-critical, so these O&M assumptions are approximate. System/market conditions and any post-commissioning refurbishments are not reflected in capex_total_aud.
