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.

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.

How this was derived
AEMO/Aurecon provides a 4-hour BESS fixed O&M benchmark; this was the closest available storage O&M proxy.

Notes
Plant-specific total project cost reported by ARENA for the 25 MW / 50 MWh Darlington Point Energy Storage System. The ARENA project page lists $32.34m total project cost, with Edify Energy operating as DPESS DevCo. For O&M, AEMO/Aurecon 2024 benchmark for a co-located 4-hour BESS was used as the closest available template; there was no site-specific O&M figure located. BESS benchmark values are for a hypothetical 200 MW plant, so the per-MW O&M assumption is a scaled benchmark, not a reported project value. Efficiency and life assumptions are from AEMO/Aurecon BESS technical parameters.
