Illustrative landed-cost range USD 1.26 M all-in CapEx at year 0 over a 25-year horizon; binding quote requires an RFQ; computed simple payback ≈ 9.31 years and discounted payback ≈ 20.91 years under the stated assumptions (8 % discount rate, USD 13,000/yr Year-1 OpEs escalating 2 %/yr, energy benefits starting at USD 162,408/yr and degrading with ESS capacity). Equipment reference: CATL LFP 280 Ah cells in a CATL EnerC containerised cabinet driven by a Sungrow ST500CP-250HV PCS, origin Shanghai/Ningbo, destination Tema port under ICC Incoterms® 2020 CIF Tema. NPV at the stated discount rate is USD 56,214; LCOS is USD 0.1306/kWh delivered. All customs rates are PENDING — lookup on the GRA ICUMS portal.
Evidence date: 2026-09-21. Limitation: figures are illustrative model outputs — no certificate, no Notified Body ID and no Ghana permit number is asserted on this page.

| Year-0 CapEx assumed (all-in) | USD 1,260,000 | Model input (battery + PCS + MV skid + BoP + freight + duties) |
| What does a binding number require? | An executed RFQ with confirmed HS national line, duty stack and freight quote | GRA ICUMS lookup + freight forwarder quote |
Reading note: simple payback answers "when do undiscounted cash flows cover the cheque"; discounted payback answers "when do present-value cash flows cover the cheque at 8 %". They are not interchangeable; both are reported above on a consistent basis from the same input set.
This page models a port energy storage system (port-ess-2mwh) for a Ghanaian port terminal: peak-shaving of diesel-generated port power, shore-power for berthed vessels and backup for refrigerated container (reefer) plugs.

Note on the "CapEx uplift" term used in market decks: the model does not apply a separate uplift multiplier. USD 1,260,000 is the single all-in year-0 figure; sensitivity to duty/VAT is handled by re-running the model after ICUMS lookup, not by an uplift.
The §5 cash flow uses a Year-1 OpEx of USD 13,000 escalating at 2.00 %/yr through Year 25 (USD 13,260 in Year 2, USD 13,525.20 in Year 3, …, USD 20,909.68 in Year 25). The line items below are bounded illustrations consistent with that envelope.
