Revenue (× MLF)

Estimated $ per interval — energy (RRP) and FCAS (regional FCAS prices), both × MLF.

🔋 State of charge

Stored energy at the start of each 5‑minute interval (AEMO INITIAL_ENERGY_STORAGE). Available up to the latest next‑day dispatch file.

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.

Notes
No plant-specific greenfield capex announcement or owner-reported total project cost was found in the searched sources. The project is operational at 155 MW / 298 MWh and is operated by Akaysha Energy, while the registered owner is Ulinda Park ProjectCo Pty Ltd. GenCost 2024-25 confirms large-scale battery costs fell 20% year-on-year, but the report excerpt accessible here did not expose a usable plant-specific capex benchmark, so capex fields remain unset rather than inferred from benchmark assumptions.
