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
No plant-specific greenfield capex figure was found in owner/developer or government search results. Hornsdale Power Reserve was completed in two phases: 100 MW/129 MWh in 2017 and a 50 MW/64.5 MWh expansion completed in 2020, bringing total capacity to 150 MW. For battery O&M, the 2024 AEMO/Aurecon review indicates BESS long-term service agreements are not typically based on fixed/variable O&M; the closest published benchmark found was an annual fixed O&M of $4,800/MW-yr for the smallest large-scale Li-ion BESS case in the 2023/24 review. No fuel or heat-rate assumptions apply.
