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.
  • State of charge — INITIAL_ENERGY_STORAGE (MWh at interval start) from UNIT_SOLUTION, published for bidirectional/storage units. Next-day data — the SOC line lags real time by up to a day.
  • 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
$20.0k (2019 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Used only as fallback context; exact solar PV fixed O&M value was not cleanly extracted from accessible lines, so server-side default was retained.

Notes
Project-specific greenfield capital investment value of A$200.6 million was reported in the EIS for the Gunnedah Solar Farm. The plant is a 110 MWac single-axis tracking solar PV facility. Fixed O&M and variable O&M were not found as project-specific values, so server-side defaults were used only for O&M fallback. No refurbishment capex identified.
