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.

$3.28M (2026 real AUD)

Reported / source value
$3.20M (2025 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
AEMO’s BESS review indicates annual O&M for batteries is highly variable and suggests fixed O&M is typically quoted on a $/MW basis; a midpoint-style proxy was used to populate the field.

Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
AEMO provides indicative battery O&M values and notes they are highly variable between OEMs; a proxy value was selected for the requested output.

Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
No plant-specific variable O&M figure was located; batteries commonly have negligible variable O&M under long-term service arrangements.

Notes
Plant-specific reported capex found in CS Energy fact sheet: $300 million investment for the 200 MW/400 MWh Greenbank Battery, commissioned in June 2025. Fixed O&M not explicitly published for this asset; used AEMO 2024 BESS indicative annual fixed O&M excluding extended warranties of $1.8m-$7.46m total annual O&M across size cases, selecting a midpoint-style proxy of ~$16,000/MW-yr for a 200 MW battery as a fallback estimate. Variable O&M is typically treated as negligible for BESS long-term service agreements; a small default of $1.50/MWh was retained from server-side fallback. No fuel or heat rate applies.
