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 public source for the Christies Beach Wastewater Treatment Plant battery construction cost, O&M, or performance parameters was found in the searched official SA Water sources. SA Water does state it has installed solar panels and battery storage on some existing land and facilities as part of its Zero-Cost Energy Future program, but the searched results did not identify this DUID's battery project cost or a battery-specific asset breakdown for Christies Beach. The site is part of SA Water's broader wastewater operations; the plant itself began operating in 1970 and was significantly upgraded in 2013. Because no verified plant-specific capex was found, no capex estimate was substituted.
