Key information
Capacity
292 MW

AEMO status In Service
Project status Operational (AI)

Mortlake Power Station is described as a 566 MW open-cycle gas-fired power station and AEMO shows it as In Service (Origin/Wikipedia/Grokipedia, 2024-2026).

Region VIC1
Coordinates -38.06310, 142.66780 (AI)

Global Energy Observatory lists Mortlake OCGT Power Plant coordinates at -38.0631, 142.6678; consistent with Wikipedia/Wikidata location references.

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.
