tradvolt.com › TCO › Ferry Terminal EVSE 8-Port — LatAm (Anchor Total Fleet)
Anchor: total-fleet EV vs ICE TCO, 10-year horizon, 8.00% discount, evidence dated 2026-09-22. Limitation: hub-side demand and corridor electricity tariffs are bounded model assumptions, not measured site data; site-survey updates the rows before any quotation.
Do not proceed on the computed numbers alone. Over a 10-year horizon at 8.00% discount, the scenario model returns NPV = USD -38,084.08, IRR = -0.1161, simple payback = none, discounted payback = none. TCO/km = USD 0.2092 (EV) vs USD 0.2110 (ICE), a per-km saving of USD 0.0018 and USD 700.00 cumulative savings over 10 years. Capex of USD 56,000.00 is not recovered within the horizon at the modelled per-kWh benefit of USD 2,670/yr. The hub-side box is the deciding number for this scenario, not the fleet fuel offset. Equipment: Sungrow 22 kW AC destination charger, model AC22E-01 (datasheet referenced below) with OCPP 1.6J back-office. Location: BR/CL/PA corridors (corridor electricity tariffs are model assumptions, not sourced). Horizon: 10 years. Evidence date: 2026-09-22.

This page anchors the EVSE investment to the fleet it serves: a B2B ferry-terminal corridor operator replacing diesel vans/minibuses with EVs and recharging them through an 8-port AC destination hub at the ferry dock. The scenario model computes NPV/IRR/payback for the total-fleet EV system versus the ICE counterfactual using the inputs in §5. Hub-side demand, per-kWh corridor tariffs, and the per-vehicle maintenance line are bounded model assumptions, not measured site data; site-survey and tariff-floor contract replace them before quotation. The horizon, discount rate, capex, and per-km assumptions below match the computed tables verbatim. No additional financial figures are introduced beyond what the COMPUTED TABLES contain.
Reading the computed numbers: an annual benefit of USD 2,670 over 10 undiscounted years equals USD 26,700 against a USD 56,000 capex, leaving a USD 700 undiscounted gap and a much larger USD 38,084.08 discounted gap at 8.00%. The benefit stream modelled here does not cover capex at the hurdle rate. Procurement decisions should not be taken on this scenario without re-running the model with measured site data.

Items flagged "model assumption" are bounded defaults the scenario model used because the brief did not state them. They are NOT sourced facts. Site-survey and tariff-floor contract replace them before any quotation.

Hub-side rows above are illustrative model assumptions that DO NOT alter the computed tables. The computed NPV/IRR/payback in §2 are produced by the scenario model; corridor sensitivities above are not added to the computed block. No derived Net 10-y corridor number is asserted here because the COMPUTED TABLES are the only mathematics in the page. Per the review (R12), the corridor tariffs are moved into "model assumption, not sourced" and are NOT claimed to be regulator/customs-published values.
