Tradvolt › Use cases › Port-ESS 2 MWh — Nigeria
Indicative 10-year landed-cost and TCO reference for a CATL EnerC 2 MWh LFP container BESS (Contemporary Amperex Technology Co., Limited) imported FOB China to Apapa / Tin Can Island port, Lagos, for port-energy-storage duty cycles (peak-shaving, RTG/STS crane buffering, reefer-plug back-up).
For the illustrative 10-year scenario below, the CATL EnerC 2 MWh LFP container BESS at Apapa/Tin Can Island port, Lagos, Nigeria shows a negative NPV of −785,840 USD, a Levelised Cost of Storage (LCOS) of 0.3097 USD/kWh, and no simple or discounted payback within the 10-year horizon. Limitations: all duty rates, fuel-displacement values and OEM commercial discounts are bounded model assumptions (see §4 and §6), not sourced facts. Authority: figures below are reproduced verbatim from the computed Tradvolt TCO model for this scenario.

Official lookup portals (please re-verify at RFQ):
Rates must be confirmed by a licensed Nigerian customs broker against the live NCS tariff before any landed-cost quotation. Tradvolt does not publish hardcoded duty/VAT rates.
Battery cells of LFP chemistry are typically classified under HS 8507.60, and static converters (PCS) under HS 8504.40. The applicable national tariff line, any exemptions and the current duty rate must be confirmed via the Nigeria Customs Service tariff portal (https://customs.gov.ng/?page_id=2512) and the WCO Harmonized System nomenclature tool (https://www.wcoomd.org/en/topics/nomenclature/instrument-and-tools.aspx). All duty rates on this page are model assumptions pending lookup.
No. All NPV, LCOS, payback and duty values are ILLUSTRATIVE — NOT A QUOTE. They show the calculation framework and must be re-validated against a current CATL proposal, the live NCS tariff, and your site's electricity tariff before any capex decision.
Request the product-level certificates by number from CATL or the issuing lab: IEC 62619:2022 (secondary lithium cells for industrial applications), UN 38.3 Rev. 7 (transport of lithium batteries), and IEC 62933-3-2:2024 (BESS performance and reliability testing). Verify each certificate number directly with the issuing body before procurement. For the Nigeria border, also engage an accredited SONCAP PVOC body at origin.
Typical routing is FCL sea freight from major Chinese export ports (Shanghai, Ningbo) to Apapa or Tin Can Island in Lagos. Indicative transit time is 35–60 days port-to-port, subject to vessel rotation and port congestion. Confirm with your freight forwarder.

Duty and VAT treatment depends on the HS national line assigned by Nigeria Customs and prevailing fiscal policy. Current rates must be confirmed via the NCS tariff portal (https://customs.gov.ng/?page_id=2512) and the FIRS VAT schedule (https://www.firs.gov.ng/wp-content/uploads/2023/01/Value-Added-Tax-Act-as-amended.pdf), and verified with a licensed customs broker.
