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).
Revenue (× MLF) — cleared MW × (5/60 h) × RRP × MLF. Chart uses MLF effective on each interval’s date; summary total uses MLF as at the end of the selected period (same as the revenue list).
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.
