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
Eraring is an existing black-coal steam station; the available source evidence did not provide a plant-specific original construction capex figure. AEMO/Aurecon 2024 cost review indicates Australian coal-fired units are typically subcritical or supercritical, and the coal case uses a net heat rate of 10.108 GJ/MWh HHV for the selected project. The fixed O&M value used here is the 2024 escalated benchmark for the black coal case from the AEMO/Aurecon review, multiplied by the unit's 720 MW capacity.
