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
Supports that Eraring is an existing operating coal station rather than a clearly documented greenfield project in the searched sources.

Notes
No reliable plant-specific greenfield construction/investment cost for Eraring/ER03 was found in the searched official and primary sources. Eraring is an existing 2,880 MW coal-fired station; the user-supplied DUID unit ER03 is part of that station, so greenfield capex is not directly inferable from available sources. Used AEMO/Aurecon 2024 technical parameter review only for the fallback heat-rate benchmark for Australian black-coal subcritical/supercritical plants, and used the user-provided emissions intensity default as an operating assumption.
