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.

Reported / source value
$205.70M (2009 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Reported financing amount associated with Hallett Hill 2; used because a direct owner construction-cost disclosure was not located.

Notes
Plant-specific greenfield capex was not found in a primary owner/government disclosure. The capex figure used is a reported 2015 financing/refinancing amount associated with Hallett Hill 2, not a direct original-construction cost announcement. Onshore wind O&M uses AEMO/Aurecon 2024 benchmark fallback. The plant is operational since 2009 and has 34 x 2.1 MW turbines.
