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
Not applicable to Ladbroke Grove; searched to verify whether any Origin owner capex announcement pattern existed, but it relates to Eraring battery, not this generator.

Notes
No reliable plant-specific greenfield capex announcement was found for Ladbroke Grove. The plant is an existing Origin gas peaker in South Australia; public sources confirm it was operational in 2000 and currently 80 MW total across the station, but no owner-reported original construction cost was located. For operating assumptions, AEMO heat-rate data lists Ladbroke Grove at 11.88 GJ/MWh (as-generated, HHV). AEMO/Aurecon 2024 OCGT benchmark for a large GT gives fixed O&M of $17,368/MW-year and 25-year design life; this was applied to the 40 MW unit as a fallback. Emissions intensity is set to the provided default because no better plant-specific emissions factor was found in the searched sources.
