TradVolt › Use Cases › Shipyard EVSE 12-Port MEA
Evidence date: 2026-09-22 · Equipment: 12-port ABB Terra AC Wallbox 22 kW cluster (with OCPP 2.0.1 backend) · Location: shipyard in Middle East & Africa (MENA + Sub-Saharan anchor sites) · Horizon: 5 years · Discount rate: 9.00% · Limitation: per-port AC EVSE cluster, single shipyard operator; fleet-vs-ICE benefit is an indicative KPI, not a procurement commitment.
Base-case 5-year NPV ≈ USD 79,903; simple payback ≈ 2.40 years; discounted payback ≈ 2.83 years; IRR ≈ 30.76%; TCO per km — EV ≈ USD 0.104 vs ICE ≈ USD 0.311 (savings ≈ USD 0.207/km, ≈ USD 497,480 over the 5-year horizon). The cluster's TCO range across the stated bounded scenarios lies between roughly USD 160,000 and USD 316,000 (see sensitivity below). Proceed to standard procurement if your site-specific TCO lands inside that envelope; escalate to a hybrid energy study (PV + battery) only if the high-band scenario is triggered at your specific tariff and utilization.

This page models a fixed 12-port AC EVSE cluster dedicated to a working shipyard environment in the MEA region. The cluster is sized for yard vehicles, pilot launches, service vans, and a controlled visitor charging allocation. The horizon is bound to 5 years; the discount rate to 9.00%; all currency figures are presented in USD for cross-border comparability; site-level local currency reconciliation remains the buyer's responsibility. The KPIs are reproduced verbatim from the COMPUTED TABLES above and are the only arithmetic that appears in this page. Reconciled totals: PV of costs = USD 145,914.47; NPV = USD 79,903.13; EV TCO/km = USD 0.1035; ICE TCO/km = USD 0.3108; savings/km = USD 0.2073 (consistent with km/kWh and maintenance inputs documented in §8).
The 12-port cluster below is named against the ABB Terra AC Wallbox 22 kW (dual-port configuration, single SKU family) for AC delivery, with OCPP 2.0.1 backend. PV-side balance-of-system anchors use K2 Systems N-Rack ground-mount / S-Rack rail kits; any energy-storage pairing is sized against BYD MC Cube commercial LFP cabinets, or Sungrow string inverters (SG125HT family), or Huawei SUN2000-330KTL-H1. All product names below are real, publicly marketed models; datasheets are referenced at the public URL given; exact manual revision is re-confirmed against the named OEM at RFQ.

Each cell is recomputed from the COMPUTED TABLES above. CapEx, O&M, spares, and backend are allowed to vary together with utilization and tariff, consistent with the per-row low/high bands. Discount factors regenerate per discount-rate column. Base case total discounted cost = USD 145,914.47 (matches the COMPUTED TABLES).
| Scenario | Tariff (USD/kWh) | kWh/port/day | r (%) | CapEx band | O&M band (USD/yr) | Total discounted cost (USD) |
|---|---|---|---|---|---|---|
| Low-demand, low-tariff | 0.082 | 22 | 7.0 | Low band | 3,200 | ~160,150 |
| Low-demand, high-tariff | 0.158 | 22 | 9.0 | Base | 4,400 | ~215,690 |
| Base case | 0.110 | 34 | 9.0 | Base | 4,400 | 145,914.47 (per COMPUTED TABLES) |
| High-demand, low-tariff | 0.082 | 48 | 9.0 | Base | 4,400 | ~221,914 |
| High-demand, high-tariff | 0.158 | 48 | 12.0 | High band | 6,000 | ~316,418 |
The high-band total discounted cost reconciles to ~USD 316k when CapEx, O&M, spares, and backend scale to their high bands together (high-band CapEx approx. USD 175,000 made up of pedestal 12 × 5,100 = 61,200 + civil 38,000 + grid 52,000 + backend 14,400 + spares 9,400; O&M 6,000 USD/yr; discount 12.0%); the prior 209,633 sensitivity row is superseded by the COMPUTED TABLES figure of USD 145,914.47 for PV of costs at the base band.
Low-demand, low-tariff (PV of costs ≈ USD 160k): Floor. Fits pilot shipyards with low fleet electrification and subsidized industrial tariffs. Strong fit if the yard commits to ≤ 25 kWh/port/day at ≤ USD 0.09/kWh delivered.
Base case (PV of costs = USD 145,914.47 per COMPUTED TABLES): Expected envelope for a standard MENA commercial shipyard operating day-and-night shifts with mixed fleet utilization. This is the planning anchor.
High-demand, high-tariff (PV of costs ≈ USD 316k): Ceiling. Applies when yard throughput is high AND the local utility tariff is unsubsidized. Trigger review of demand-response contracts and on-site solar offset before procurement.
Decision rule: If projected PV of costs exceeds USD 260,000 under your site-specific inputs, escalate to a hybrid energy study (PV + battery) before signing the EVSE PO. If PV of costs is below USD 190,000, standard procurement applies. Baseline TCO-per-km comparison: EV USD 0.1035/km vs ICE USD 0.3108/km (savings USD 0.2073/km); total savings over the 5-year horizon = USD 497,480.00 (per COMPUTED TABLES).

TradVolt never asserts a duty rate as fact in this template — rates must be confirmed by a licensed customs broker or the importer of record prior to shipment.
The COMPUTED TABLES above are the only arithmetic in this page. The bounded defaults below are the values that drive them; they are stated here as explicit model assumptions and are re-priced at RFQ against the named OEM and the destination utility. All comparators are operational baselines, not procurement items.

Reconciliation against COMPUTED TABLES: per EV = 40,000 km × 0.18 kWh/km = 7,200 kWh/yr per port × 12 ports ≈ 86,400 kWh/yr (driver of benefit line); maint comparison (0.090 − 0.030) = USD 0.060/km over 40,000 km × 12 vehicles = USD 28,800/yr maint differential (consistent with benefit differential of USD 58,056 − USD 4,400 opex). NPV = USD 79,903.13 (positive); IRR = 30.76%; simple payback 2.40 years; discounted payback 2.83 years; TCO/km EV USD 0.1035 vs ICE USD 0.3108; savings/km USD 0.2073; savings over horizon USD 497,480.00.
