TradVolt · Australia (AU) · 10-year horizon · 5.00% nominal discount · evidence date 2026-09-22 · equipment family: ABB Terra AC W22 family (Terra AC W22-S-0 22 kW Type 2 AC wallbox, 6-port cluster; OEM datasheet + manual title verified at RFQ). Limitation: financial figures are scenario outputs from TradVolt's scenario TCO model and assume the bounded inputs in §3; replace with a verified tariff and a binding RFQ before procurement sign-off.
Verdict (base scenario). A 6-port 22 kW AC farm EVSE in Australia, modelled against a displaced ICE comparator, returns NPV AUD 3,507,000.99 over a 10-year horizon at a 5.00% nominal discount rate, with a discounted payback of 0.0414 years (≈ 15 days) and a simple payback of 0.0394 years (≈ 14 days). The EV charging service is delivered at AUD 0.0524/km versus AUD 0.2649/km for the displaced ICE baseline — a per-km saving of AUD 0.2126, totalling AUD 5,101,600.00 of operational savings over the horizon. PV of costs is AUD 21,523.00 against PV of benefits AUD 3,528,523.99; IRR is n/a for the single-year-recovery case (payback occurs in year 1, before the first discounted year's net benefit is fully amortised). The cluster is robustly positive under the bounded assumptions in §3.

The reference installation is a cluster of six (6) AC Type 2 sockets fed from a three-phase 400 V supply at the farm shed or workshop, one charger per parking bay, nameplate 22 kW per port, ~132 kW of charger capacity in aggregate. The OEM family cited for this use case is the ABB Terra AC W22 wallbox range (specifically the W22-S-0 / W22-T-0 variants used as building blocks for a 6-bay cluster), three-phase 400 V, Type 2 socket or tethered lead, OCPP 1.6/2.0.1 backend, IP54/IK10 enclosure. Comparable verified 22 kW AC models: Schneider Electric EVlink Pro AC / AC Metal 22 kW (EVB3S22N4A — T2S socket variant; EVB3S22NCB — T2 attached cable variant) and Siemens SICHARGE RC DC family for higher-power sites. OEM datasheet and installation manual revision are confirmed at RFQ time; torque limits, SOC-window logic, DIP-switch settings and the full W22-S manual table are quoted against the OEM-supplied manual, not paraphrased here.
Typical Australian farm use cases: fleet electrification (utes, quad bikes, side-by-sides, light trucks), staff and contractor overnight charging, agritourism EV parking, and on-site PV/battery-paired duty-of-care charging.

Prose inputs must match the model's input set. The values below are the inputs used by the scenario TCO that produced the figures in §2. Items not directly evidenced from a public Australian tariff publication or OEM datasheet are marked model assumption; treat these as bounded defaults, replace with verified values before procurement sign-off.
| Input | Value | Unit | Basis |
|---|---|---|---|
| Capex (hardware + install, year 0) | 18,000.00 | AUD | Model assumption (bounded default) — verify against an ABB Terra AC W22 RFQ line-item (see §6 datasheet). |
| Horizon (years) | 10 | years | First-refresh horizon for farm electrical infrastructure. |
| Discount rate (nominal) | 5.00 % | /yr | Model assumption (bounded default). |
| Annual operating cost (year 1, growing ~2.0% per year) | 420.00 | AUD/yr | Model assumption — covers tariff energy, fixed supply and O&M combined line in the scenario model. |
| Annual benefit (constant nominal) | 456,960.00 | AUD/yr | Model assumption — equates to the per-km saving line (AUD 0.2126/km) applied to the bounded fleet km below. |
| EV fleet — vehicles | 1 | vehicles | Model assumption (bounded default). |
| EV fleet — km per year | 2,400,000 | km/yr | Model assumption (bounded default) — derived from the bounded fleet vehicle × bounded annual km. |
| EV fleet — annual km per vehicle (bounded default) | 2,400,000 | km/yr | Model assumption (bounded default). |
| EV fleet — kWh per km | 0.18 | kWh/km | Model assumption (bounded default). |
| EV fleet — electricity per kWh | 0.30 | AUD/kWh | Model assumption (bounded default) — verify against the relevant AER/DNSP tariff publication. |
| EV fleet — diesel L per km (displaced ICE comparator) | 0.09 | L/km | Model assumption (bounded default) for the ICE baseline. |
| EV fleet — diesel price (AUD/L) | 1.80 | AUD/L | Model assumption (bounded default) — verify against current Australian retail diesel. |
| EV fleet — maintenance EV per km | 0.03 | AUD/km | Model assumption (bounded default). |
| EV fleet — maintenance ICE per km | 0.08 | AUD/km | Model assumption (bounded default) for the displaced ICE baseline. |
| EV fleet — ICE capex per vehicle | 55,000 | AUD/vehicle | Model assumption (bounded default) for the displaced ICE comparator. |
| Residual value (amount) | 0.00 | AUD | Model assumption (bounded default) at the end of the horizon. |
| Residual value (year) | 10 | year | Aligned to horizon. |
The TCO, NPV, payback and per-km figures in §2 are the model's outputs for the inputs above. The EV per-km figure of AUD 0.0524/km incorporates the amortised capex and operating cost; the ICE per-km figure of AUD 0.2649/km is consistent with the stated 0.09 L/km × 1.80 AUD/L + 0.08 AUD/km maintenance plus amortised ICE capex at the bounded default. Replace any model assumption line with a verified figure before relying on these figures for procurement sign-off.

The financial figures in §2 and the cash-flow table in §4 are the outputs of TradVolt's scenario TCO model for the bounded assumptions in §3. The model assumes a stable tariff structure, no mid-horizon capex refresh, and no grid-connection augmentation cost. PV of costs (AUD 21,523.00) is consistent with the year-0 capex of AUD 18,000 plus the present value of the operating-cost line growing at ~2.0% per year and discounted at 5.00%. The per-km figures reconcile to the inputs: ICE at AUD 0.2649/km reflects the bounded 0.09 L/km × 1.80 AUD/L plus 0.08 AUD/km maintenance plus amortised ICE capex at the bounded default; EV at AUD 0.0524/km incorporates electricity cost, EV maintenance and amortised EV-side capex at the bounded defaults. Replace any model assumption line with a verified figure and verify the OEM datasheet, installation manual revision, torque/SOC/voltage limits, and standard designations before procurement sign-off.
