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
Project-specific greenfield capex found in contemporaneous reporting for Lake Bonney Stage 2: $400 million for 53 turbines / 159 MW. This is used for LKBONNY2. O&M is not separately reported in the sources reviewed; internal default fixed O&M was not used because the request prioritised source-backed information and no plant-specific O&M figure was found. Lake Bonney 2 is part of the broader Lake Bonney wind farm complex, but the $400 million figure aligns with the 159 MW Stage 2 project.
