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
Hume Power Station at Hume Dam is listed by GSP Energy as a 58 MW hydro station with two 29 MW Kaplan units and commissioning in 1957. I did not find a plant-specific original construction/investment cost for this DUID/asset in the reviewed sources, so capex remains unfilled rather than inferred from benchmarks. A separate Hume Battery Energy Storage System project exists within the Hume Dam precinct, but that is not the hydro generator's greenfield capex.
