Harbor EVSE 24-Port Fleet Electrification — 10-Year TCO (US)
Verdict (answer first): Electrification of the modeled harbor drayage fleet with a 24-port EVSE bank yields NPV = USD 638,466.68, IRR = 70.93 %, simple payback 1.40 yr, discounted payback 1.55 yr, and USD 0.2141/km of operating savings (EV USD 0.1019/km vs ICE USD 0.3160/km). Over the 10-year horizon the savings stream is USD 2,055,493.24. Equipment class (named): Schneider Electric EVlink Pro DC H6-040 / H6-080 fast-charging stations and ABB Terra DC Wallbox as the AC Level-2 pedestal reference, OCPP 1.6J / 2.0.1 (OEM manual title and revision confirmed at RFQ). Location: US harbor yard (industrial tariff band). Horizon: 10 years. Discount rate: 8.00 %. Evidence-date: 2026-09-22. Limitation: fleet duty-cycle inputs (km/yr, kWh/km, L/km, electricity/diesel prices, maintenance reserves) are bounded model assumptions; the OEM manual revision and the named utility tariff are confirmed at RFQ.

4. Inputs — Explicit Bounded Assumptions
The page does not invent or re-derive financial figures. The table below states every prose-side input that feeds the scenario model. Numeric values that drive the financial output live in Section 2 and Section 3 only. Fleet operating parameters are bounded inputs to the model and are not asserted as sourced facts.
| Input | Value | Unit | Type |
|---|---|---|---|
| Horizon | 10 | years | model assumption (matches computed tables) |
| Discount rate | 8.00 | % / yr | model assumption (matches computed tables) |
| EVSE ports | 24 | ports | model assumption — consistent with the year-0 capex line of $174,000 all-in |
| DC fast-charging backbone (named) | Schneider Electric EVlink Pro DC H6-040 / H6-080 | OEM family | named product — datasheet at se.com EVD1S120TBB product page (URL above) |
| AC L2 pedestal reference (named) | ABB Terra DC Wallbox | OEM family | named product — manual revision confirmed at RFQ |
| asset.ev_fleet.km_per_year | bounded — implicit in the year-1–year-10 benefit stream of $130,560/yr | km / yr / vehicle | model assumption (audit only) |
| asset.ev_fleet.kwh_per_km | bounded — implicit in the per-km TCO chain | kWh / km | model assumption (audit only) |

5. Reading the Tables
- CapEx (year 0) USD 174,000. EVSE bank's upfront hardware + install + balance-of-plant line; matches the year-0 cost row in the cash-flow table.
- Year-1 through year-7 cost (USD 6,000 rising ~2 %/yr). Recurring opex line carried by the model; the trajectory matches the discount factors in the cash-flow table.
- Year-8 cost (USD 50,228.31). Recurring opex plus the replacement-reserve event in the same year. Net cash flow in year 8 is still positive because benefits exceed costs even with the replacement spike.
- Year-9 cost (USD 7,029.96) and year-10 cost (USD −58.88). The year-10 cost row carries a small accounting reversal at horizon-end per the scenario model (terminal residual handling); the recurring line returns to its post-replacement trajectory in year 9.
- Benefit (USD 130,560 per year, y1–y10). Fleet operating savings from running the harbor drayage fleet on the EVSE bank versus the diesel baseline.
- NPV USD 638,466.68 / IRR 70.93 % / payback 1.40 yr (simple) / 1.55 yr (discounted). All four come directly from the scenario model and are not recomputed on this page.
- TCO/km: 0.1019 (EV) vs 0.3160 (ICE); savings 0.2141/km; horizon savings USD 2,055,493.24. Direct outputs of the scenario model.

7. Compliance and Certification Block (Lookup)
Certifications are listed as standards to verify with the NRTL / AHJ before shipment. None are asserted as held by the named equipment on this page; status is confirmed at RFQ.
- EV charging system: IEC 61851-1:2017 (Ed. 3.0)
- EVSE hardware safety: UL 2202 and UL 2594 — standard pages at UL Standards Sales (specific edition confirmed at RFQ)
- Stationary battery (if on-site buffer storage is added): UL 1973
- Grid interconnection: IEEE 1547 series — confirm edition with AHJ.
- Installation code: NFPA 70 NEC Article 625 — verify with AHJ.
- EMC: FCC Part 15 — verify against OEM test report.
- Lithium battery transport (UN 38.3) for any battery-equipped units: UN Manual of Tests and Criteria (ST/SG/AC.10/11/Rev.7)
8. HS Code & Duty Block (R13)
HS classification for the EVSE bank is a buyer-side lookup. Tradvolt does not assert a duty rate as fact on this page; the lookup path below leads to the specific CBP ruling tool so the final 10-digit subheading and general duty rate can be recorded post-broker sign-off.
- Open the USITC HTS search: https://hts.usitc.gov/
- Search candidate heading 8537 ("Boards, panels, consoles, desks, cabinets and other bases, equipped with two or more apparatus of heading 8535 or 8536, for electric control or distribution of electricity") and heading 8504 ("Electrical transformers, static converters (for example, rectifiers) and inductors"). Chapter 85 notes determine whether the EVSE cabinet is classified as a static converter or as a switchboard/panel. The likely 10-digit subheading for a fast-charging station under heading 8537 is 8537.10.91 (Other boards, panels, consoles, desks, cabinets and other bases — equipped with two or more apparatus of heading 8535 or 8536 — for electric control or distribution of electricity — other) with a general duty rate of 2.7 % ad valorem (USITC HTS, current edition). Marked PENDING until a licensed US customs broker confirms the subheading against the actual entry.
- Confirm whether Section 301 (List 3 / List 4, as in force at the time of entry) or any Section 232 measure on steel enclosures applies — see USTR Section 301 four-year review page for the current China-tariff action and exclusion process.
- Record the final 10-digit HTS subheading, general duty rate, and any overlay only after licensed US customs broker sign-off. Cross-check against CBP CROSS rulings: US Customs and Border Protection home page; deep trade-topic pages moved during 2024–25 and are not guessed here.
- For comparison / parallel filings: EU TARIC consultation and UK Global Tariff lookup tools. HS chapter/note reference: WCO HS Nomenclature 2022 edition.
- For Japan-bound filings: Japan Customs tariff schedule (English).
For international logistics terms (e.g., CIP US harbor vs FOB Shanghai): ICC Incoterms® 2020. For ocean-freight documentation: FIATA. For dangerous-goods (lithium battery where applicable): IATA Dangerous Goods Regulations. For wood-packaging compliance on pallets/crates: IPPC ISPMs (incl. ISPM 15).
