Import LFP Rack 100kWh from China to Bahrain — Hotel-Solar TCO & Landed Cost
Verdict (illustrative, model output): For the reference 100 kWh LFP rack (CapEx 45,000 USD; 1 cycle/day at 80% DoD; net shift delta 0.01 USD/kWh; 8% discount rate; 10-year horizon), the computed NPV is -48,942.70 USD, simple payback is not reached, discounted payback is not reached, and LCOS is 0.2749 USD/kWh. Equipment family: CATL EnerC 100 commercial LFP rack (CATL CTP/CTC architecture, 100 kWh class), comparable with Sungrow ST114 / ST129 C&I LFP cabinets and Huawei LUNA2000-215 Series — exact SKU confirmed at RFQ. Location: Manama, Kingdom of Bahrain. Horizon: 10 years. Evidence date: 2026-09-22. Limitation: net shift delta (0.01 USD/kWh) reflects charge cost ~0.09 USD/kWh against a flat self-consumption value of 0.10 USD/kWh; higher ToU delta materially compresses payback (see §3).

| 10 | 806.69 | 128.13 | -678.55 | 0.4632 | -314.30 | 24,345.43 |
Note on the §3 verdict: at the modeled inputs (CapEx 45,000 USD; net shift delta 0.01 USD/kWh; 8% discount; 10-year horizon), annual net cash flow is negative in every year, so simple and discounted payback are not reached and IRR is undefined — consistent with NPV = -48,942.70 USD and the COMPUTED TABLES above. Higher ToU delta materially compresses payback and would change the verdict.
