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 reliable plant-specific greenfield capex announcement was found for Eraring GT (ERGT01) after searching owner, project, and government sources. AEMO benchmark values were used only for operating assumptions. Eraring GT is listed as a 41.5 MW OCGT diesel unit at Eraring; the exact commission date was not located in the search results.
