Revenue (× MLF)

Estimated $ per interval — energy (RRP) and FCAS (regional FCAS prices), both × MLF.

🔋 State of charge

Stored energy at the start of each 5‑minute interval (AEMO INITIAL_ENERGY_STORAGE). Available up to the latest next‑day dispatch file.

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.
State of charge — INITIAL_ENERGY_STORAGE (MWh at interval start) from UNIT_SOLUTION, published for bidirectional/storage units. Next-day data — the SOC line lags real time by up to a day.
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.

Capex total (greenfield)	$65.50M Shown in table $65.50M (2026 real AUD) Reported / source value $60.00M (2023 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups). How this was derived Genex stated the Bouldercombe Battery Project total capital spending budget was $60 million.

Capex / MWh storage derived	$655,022 Shown in table $655.0k (2026 real AUD) Reported / source value $600.0k (2023 nominal) Adjusted to 2026 real AUD using Australian CPI (All Groups). How this was derived Derived from reported total capital spending budget divided by 100 MWh.

Notes
Greenfield capex based on Genex-reported total capital spending budget of $60 million including finance costs and contingency funds for the 50MW/100MWh project. Fixed OPEX uses the provided server-side default for battery storage; variable OPEX uses the provided default. Project was fully operational from 2H CY2023.
