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
Project-specific greenfield capex was not found in the searched owner/developer and related sources. The owner/developer sources confirm a 100 MW / 200 MWh battery, construction start in December 2021, financial close in October 2022, and operations beginning in 2023 rather than a disclosed total project cost. Neoen states the asset will be maintained for at least 25 years. No verified plant-specific O&M, fuel, or heat-rate assumptions were found for a battery asset; emissions intensity is zero for operational generation emissions.
