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.

Shown in table
$94.59M (2026 real AUD)

Reported / source value
$70.00M (2017 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Owner/developer project page states the Hayman Solar Farm had a project value of approximately $70 million.

Reported / source value
$1.21M (2017 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
Per-MW capex is calculated by dividing the reported project value by the installed capacity stated on the same project page.

Reported / source value
$20.0k (2017 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
The source supports the technology class and maintenance implication, but the exact fixed O&M number was not clearly surfaced in the extracted lines; therefore the field is left as a cautious fallback assumption.

How this was derived
No plant-specific variable O&M was found; default server-side fallback retained.

Notes
Project value of approximately $70 million reported by Edify Energy. Site commercial operations began in August 2018; the reported project value is treated as the greenfield construction/investment cost. No separate refurbishment cost identified.
