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.

Table total may differ if recalculated from $/MW × registered capacity after CPI adjustment.

How this was derived
AEMO/CSIRO ETC capex benchmark for black coal sub-critical turbine (existing generator/ETC mapping) was not retrieved from the sources in this run; internal server-side default used.

How this was derived
No reliable official refurbishment/upgrades cost source extracted for ER04 in retrieved results.

How this was derived
No AEMO retirement O&M estimate table values for the exact technology mapping (black coal sub-critical turbine, existing) were extracted in retrieved sources; internal server-side default applied.

How this was derived
AEMO heat-rate dataset lists Eraring static heat rate 9.55 GJ/MWh (HHV).

Notes
Web search returned AEMO heat-rate data for Eraring (existing generator) showing a static heat rate of 9.55 GJ/MWh, but not the required AEMO/CSIRO ETC capex benchmark for black coal sub-critical turbine, nor an AEMO/CSIRO fuel-cost parameter and refurbishment-cost data for ER04 specifically. Therefore capex and O&M/fuel/performance fields use the provided internal technology defaults (server-side). Commissioning/online date and any refurbishment/upgrades were not reliably sourced from official Origin/AEMO documents in the retrieved results.
