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
Hallett 5 (The Bluff) is a 52.5 MW onshore wind farm in South Australia. AGL announced a total development cost of approximately A$120 million in February 2010 for construction beginning July 2010 and completion anticipated in December 2011. Operational timing in secondary sources indicates commercial operation by September 2011 / March 2012; capex_year set to the announcement/construction year 2010. No reliable plant-specific O&M benchmark was located in the available search results, so server-side fallback values were not used except for variable O&M default in the provided schema context.
