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.

How this was derived
Derived from total capex and energy capacity, since battery duration is 1 hour.

Notes
Project is the AGL Broken Hill grid-forming battery (50 MW / 50 MWh). I used the owner-reported actual project capex of A$45m from AGL's FY25 half-year results (published 2026-02-11). AGL/ARENA earlier reported total project cost of A$39.4m / A$39.4m; because the latest owner-reported actual construction cost is higher, capex_total_aud is set to A$45m. No project-specific O&M or fuel cost disclosures were found in the searched sources, so those fields are left null. Battery storage has no fuel cost and zero direct emissions in operation.
