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.

Financial overview

2026 real AUD. Monetary values are CPI-adjusted to 2026 real Australian dollars. Greenfield capex uses AEMO benchmarks when plant-specific cost is unknown.

Notes
Eraring is a 2,880 MW coal-fired power station; no plant-specific greenfield construction cost was found in the searched official sources, so no capex figure is reported. Used AEMO/GHD black coal super-critical O&M estimates as the closest published benchmark for an operating coal unit, and AEMO heat-rate data listing Eraring at 8.91 GJ/MWh incremental heat rate. Eraring construction began in 1976 and the first unit was commissioned in March 1982; however, no original build cost was identified in the sources searched. The NSW Government agreement indicates Eraring is expected to cease operation by no later than 30 April 2029, but that is an operating/closure note, not capex.
