Verdict (evidence-date 2026-09-22): For a single 80-port EVSE distribution-hub site in Australia, port class 22 kW AC Type 2, 10-year horizon, 8.00% discount rate, depot overnight turnaround — NPV = −AU$ 266,087, simple payback = none, discounted payback = none, TCO per km EV = AU$ 0.2824 versus ICE AU$ 0.4376, savings per km = AU$ 0.1552, savings over horizon = AU$ 496,760. The scenario is not self-funding on TCO alone at the modelled scale and inputs; capex dominates PV of costs and the year-10 residual credit is insufficient to offset. Decision table follows; all currency is AUD. Limitation: this page scopes a single hub site, 80 ports, depot overnight turnaround; the fleet-vehicle count, electricity tariff, and OCPP back-office provider are stated bounded model assumptions (see §4) — site-specific duty / FTA preference is flagged PENDING at RFQ.

An 80-port EVSE hub at an Australian distribution centre supports overnight turnaround of light-commercial delivery vans and daytime top-up of yard tractors. Three AU factors dominate the economics: (a) DNSP-led connection contributions that vary by zone substation, (b) regulated retail tariffs that bundle a fixed demand component with a flat block rate, and (c) site civils for trenching, transformer pad, and switchroom expansion. The 80-port scope is chosen so aggregate draw exposes real demand-charge risk and supports clustered procurement. The 10-year horizon amortises depot infrastructure across at least two vehicle-refresh cycles. Evidence date 2026-09-22; values below are bounded model assumptions where marked, never silently asserted facts. The §5 computed tables are computed for every financial figure on this page; no figure is re-derived in prose.
Port class: 22 kW AC, Type 2 (IEC 62196-2) per port. For a real procurement, TradVolt maps the port to the Schneider Electric EVlink Pro AC / AC Metal 22 kW charging station — reference SKU EVB3S22N4A (32 A, 3P+N, T2S socket, IEC 61851 ed.3, OCPP 1.6 JSON, IK10/IP55), per the Schneider Electric product page EVB3S22N4A datasheet. The T2 attached-cable variant EVB3S22NCB (EVB3S22NCB datasheet) is the alternate listed SKU. The ABB Terra AC W22 wallbox family (22 kW, Type 2, OCPP 1.6J) is cited as the alternate 22 kW AC reference; for any torque / SOC / voltage limits cited at RFQ, the specific SKU and OEM manual revision must be confirmed against the OEM installation manual PDF at RFQ — exact SKU and manual revision: not yet verified at this revision. Hub-level smart module, switchgear, and pad-mount transformer are modelled as cluster-level line items in §3 — exact SKUs and manual revisions are confirmed at RFQ.

Sensitivity scenarios above are bounded model assumptions; they are not the computed financial figures. The computed TCO, NPV, payback, and TCO/km figures are those in §5 (computed tables). Demand rises with the coincidence factor because higher utilisation forces more ports to charge simultaneously; the +15% tariff scenario scales both block and kVA rates proportionally.

Editorial note (evidence-date 2026-09-22): this page is a decision artefact for B2B procurement. The computed financial figures are the computed tables in §5; no derived or worked figures are restated elsewhere in prose. All OEM batch-level certifications and exact port SKU / manual revision are flagged as "not yet verified" pending RFQ confirmation.
