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
Greenfield Hunter Power Project target cost was reported by Snowy Hydro as $950 million after the 2023 project reset. The site has 660 MW initially available to the grid, but the registered unit capacity is 375 MW for HUNTER2; per-MW capex is therefore calculated using the DUID capacity provided by the user. O&M and performance values are taken from AEMO/Aurecon 2024 technology-cost review for large OCGT-style gas turbines. Heat rate source is an AEMO/Aurecon table for large gas turbines; used as an OCGT proxy.
