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.

Capex total (greenfield)
$262.71M

Shown in table
$262.71M (2026 real AUD)

Reported / source value
$186.00M (2014 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
The only plant-specific dollar figure located from the owner was a refinancing amount, which is not the same as original capex but is the closest project-specific source-backed value found.

How this was derived

Reported / source value
$15.0k (2014 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Retrieved AEMO onshore-wind lines support the technology classification and life assumption, but the exact fixed O&M value was not successfully captured, so the fallback default was retained.

Notes
Plant-specific capex was not directly disclosed as original construction cost; the closest source-backed figure found is Palisade's A$186m refinancing for Hallett 1 Wind Farm. This is used as a proxy for reported project value, not as a benchmark estimate. The wind farm has operated since 2008; capex year set to 2014 only to match the refinancing source year in the absence of a construction-cost source, so this field should be reviewed. For operating assumptions, AEMO 2024 indicates onshore wind is a mature technology with a typical design life of 25 years; variable O&M is not separately stated in the retrieved lines and is set to the provided fallback default.
