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.

Notes
Pacific Blue stated the project is a $100 million, 60 MW / 130 MWh grid-scale battery at Clements Gap; this is a reported project investment figure. Later Pacific Blue material describes the battery as 60 MW / 120 MWh, so the reported cost is paired here with the announced 60 MW project capacity and the 2024 construction start year. Operational lifespan noted by Pacific Blue is 20 years.
