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
Could not find a plant-specific greenfield construction cost for Lake Bonney 3 from the owner/developer or government sources in the available searches. Available sources confirm Stage 3 is a 39 MW onshore wind project commissioned in 2009/2010, but do not state the total project capex. Use server-side fallback only if needed downstream. No refurbishment cost identified.
