Use case: Cold-storage energy storage system (coldstorage-ess-100kwh) — a 100kWh lithium iron phosphate (LFP) cabinet deployed to support refrigeration loads in cold-chain facilities in Kenya. Vertical: LFP battery storage. Route: China → Port of Mombasa → Nairobi site. Reference equipment family: CATL LFP 280Ah cell-based commercial cabinet (e.g., a CATL-based 100kWh LFP ESS cabinet). Specific SKU and OEM datasheet are confirmed via RFQ.
Headline verdict (illustrative, 25-year horizon, 8.00% discount rate, evidence-date 2026-09-21): For a CATL LFP 280Ah-based 100kWh cabinet imported into Kenya under the stated bounded assumptions, the base-case 25-year NPV is −53,012.82 USD, discounted payback is None, simple payback is None, and the levelised cost of storage is 0.4293 USD/kWh. Landed CapEx (model default) ≈ 55,000 USD; the full Kenyan duty stack (import duty, VAT, excise, IDF, RDL) is PENDING — lookup on the KRA iTax tariff portal and is not embedded in the NPV. Limitations: duty/VAT/levies excluded; auxiliary load, marine insurance, KEBS PVoC fee, clearing & forwarding, and inland transport are out-of-model; degradation, residual value, usable percentage, cycles/year and charge cost are bounded model assumptions shown in §8.

Reading the table: Net annual benefit turns negative in year 11 (−155.41 USD) and continues to decline as energy throughput falls with battery degradation. Cumulative undiscounted net reaches break-even in year 10 (36.54 USD) but discounted payback is None because the discounted benefit stream does not recover the 55,000 USD year-0 outlay within 25 years at an 8.00% discount rate. LCOS of 0.4293 USD/kWh is the model output under §8 assumptions.
Required documentation for a 100kWh LFP cabinet entering Kenya. Each item below must be requested from the OEM with the specific certificate number and issuer name:
Certificate numbers, issuing bodies, and validity dates are NOT provided here. Confirm with OEM documentation and KEBS before shipment.
| HS national line | Program | As-of | SoT |
|---|---|---|---|
| PENDING — lookup (likely 8507.60 or 8504.40) | Kenya import duty + VAT + excise / RDL / IDF (if any) | 2026-09-21 | PENDING — lookup |
Confirm the exact HS national line for the LFP cabinet (with integrated BMS/inverter or without) on the official KRA tariff portal before any clearance. Tradvolt does not hardcode duty rates; binding landed-cost calculations require the buyer or their clearing agent to retrieve current rates. The TCO in §3 excludes all KRA duty-stack items.

The draft sensitivity table used a placeholder CapEx of 55,000 USD against 50,000 kWh/yr × 0.30 USD/kWh − 4,000 USD OpEx, producing a "5.0-year payback" headline. That headline is inconsistent with the computed tables in §3–§4 and has been removed. Under the computed model:
Directional sensitivities (illustrative, not recomputed): higher delivered energy per year, higher displaced-energy tariff, lower CapEx, or a longer operating window before end-of-life can each move NPV toward zero or positive; conversely, including the KRA duty stack (currently PENDING — lookup) and KEBS PVoC fees will worsen CapEx and NPV.
The TCO in §3–§4 was computed by the scenario model from the bounded inputs below. These are model assumptions, not sourced facts. They must be replaced with values from the OEM datasheet and the RFQ response before any commercial commitment.
