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.

Financial overview

2026 real AUD. Monetary values are CPI-adjusted to 2026 real Australian dollars. Greenfield capex uses AEMO benchmarks when plant-specific cost is unknown.

How this was derived
No plant-specific gas supply cost was found in the searches, so the provided fallback was retained.

Notes
No plant-specific greenfield construction cost was found in official owner/government sources. The only specific dollar figure found was a 2023 Queensland Government-funded $75 million hydrogen expansion/replacement project, which is a refurbishment/transition project rather than original construction capex. OCGT O&M and heat-rate values were taken from AEMO/Aurecon 2024 technical parameters for large GT / OCGT-type plants and the server-side fuel cost fallback was used.
