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.
