Commercial HPWH certificate range estimator
Estimate the VEEC (Victoria) or ESC (NSW) opportunity for a 10–200 kW commercial heat pump water heater from inputs you already know: capacity, tank volume and refrigerant. Results are a typical midpoint and a P10–P90 range, not a single figure.
Combined thermal capacity of all heat pumps. Modelled range 36–1,163 kW.
Combined storage across all tanks. Modelled range 459–19,092 L.
Refrigerant of the heat pump units.
Spot price moves. Default $85.

Estimated VEEC range
VEU Activity 44A(ii) — replace electric · ±29% typical error on public inputs
A system like this typically earns 1,547–2,586 VEECs, worth roughly $131,495–$219,810 at $85/VEEC.
At a glance — VEECs by capacity
VEU Activity 44A(ii) — replace electric, CO₂, ~5 L/kW storage. Updates with the toggles above.
| Capacity | Typical VEEC | Range (P10–P90) | ≈ value |
|---|---|---|---|
| 20 kW | 559 | 445–743 | $47,515 |
| 50 kW | 567 | 451–754 | $48,195 |
| 100 kW | 809 | 644–1,076 | $68,765 |
| 200 kW | 1,944 | 1,547–2,586 | $165,240 |
Estimates use the EnergyAE commercial modelling database (177 systems ≥10 kW) and the regulated VEU Activity 44 and ESS Schedule F equations, scaled across the relevant climate zones (VIC zones 4+5, NSW zones 3+5).
Figures are AS/NZS 4234-validated factors (EEFm 0.393, ElecCCF 1.06, GasCCF 0.47, metro network factor). They are an estimate for business-case purposes only — a registered certificate quantity requires full TRNSYS modelling of your specific system.
