Import CATL EnerC 1 MWh LFP Container BESS from China to Singapore — Commercial Peak-Shaving — Total Cost of Ownership
Verdict (evidence-date 2026-09-22): On the bounded defaults in Section 5, the scenario TCO model over a 25-year horizon at an 8.00% discount rate returns NPV = -SGD 2,120,443.92, simple payback = none, discounted payback = none, IRR = -0.0910, and LCOS = SGD 0.8862/kWh. Equipment: Contemporary Amperex Technology Co., Limited (CATL) EnerC, 1 MWh-class LFP containerised BESS (1C / 0.5C variant). Location: Singapore. Horizon: 25 years. Evidence-date: 2026-09-22. Limitation: per-kWh charge cost (SGD 0.25/kWh) and per-kWh discharged value (SGD 0.381/kWh) are explicit model assumptions, not sourced facts; replace with your retail tariff schedule and validated OEM throughput curves before relying on the output. Verdict: do not proceed on these inputs.[1][2]

5. Bounded Model Assumptions (not sourced facts)
The draft did not state the per-unit economics that drive the benefit stream. The scenario model was supplied with the following bounded defaults. Replace each with RFQ- and tariff-confirmed values before relying on the output.
| Model input | Default used | Source / convention |
|---|---|---|
| opex.fixed (annual fixed OpEx) | SGD 0 / yr | Model default — no fixed OpEx recognised inside horizon |
| opex.escalation_pct | 0.0 % / yr | Model default — flat OpEx; escalate to your site's opex escalation if non-zero |
| residual_value.amount | SGD 0 | Model default — no terminal salvage |
| residual_value.year | n/a (residual = 0) | Model default |
| asset.ess.degradation_pct_per_year | 2.0 % | Model default consistent with year-1 delivered energy of 297,000 kWh falling to 182,886.76 kWh by year 25 (see Energy column of cash-flow table) |
| asset.ess.charge_cost_per_kwh | SGD 0.25 / kWh | Model assumption — Singapore regulated low-tension tariff band; verify with SP Group published tariff |
| asset.ess.value_per_kwh_discharged | SGD 0.381 / kWh | Model assumption — net of charge cost and 90% round-trip efficiency; reconciles to year-1 benefit of SGD 30,657.00 at 297,000 kWh delivered |
| Round-trip efficiency (used) | 90 % | Implied by benefit formula; OEM-published RTE for CATL EnerC to be confirmed at RFQ against the OEM Installation & Operation Manual, current rev[3] |
| Depth of discharge | 90 % | Conservative for LFP cycle life; per OEM warranty terms[3] |
| Cycles per year | 1 cycle / day | Model assumption (= 330 cycles / yr against a 360-day dispatch window); OEM cycle-life curve to confirm[3] |
| Auxiliary load (cooling, BMS, controls) | 3%–5% of nameplate | Industry convention; OEM datasheet to confirm[3] |
| Routine O&M | 1%–2% of CapEx / yr | Industry convention; OEM warranty / service-contract terms to confirm[3] |
| Marine insurance | 0.3%–0.5% of CIF | Industry convention for containerised BESS; insurer quotation to confirm[6] |

9. Frequently Asked Questions
Q1. Does the 1 MWh CATL EnerC BESS pay back within 25 years in Singapore on the bounded model defaults?
No. On the bounded defaults in Section 5 the scenario model returns NPV = -SGD 2,120,443.92, simple payback = none, discounted payback = none, LCOS = SGD 0.8862/kWh, IRR = -0.0910. Replace the per-kWh charge cost (SGD 0.25/kWh) and per-kWh discharged value (SGD 0.381/kWh) with your tariff schedule and the OEM's RTE and cycle-life curves from the CATL EnerC Installation & Operation Manual, current revision, before relying on the output.
Q2. What HS code applies to a CATL EnerC LFP container BESS imported into Singapore?
Lithium-ion battery storage systems typically fall under Chapter 85 of the Singapore Harmonized System. The exact national line, applicable duty rate, and any GST treatment must be confirmed on the Singapore Customs HS code lookup and via IRAS.
Q3. Which OEM and exact model designation is the basis of this TCO?
Contemporary Amperex Technology Co., Limited (CATL), EnerC 1 MWh-class LFP containerised BESS, 1C / 0.5C configurable variant. See the CATL ESS product landing; SOC window, max charge/discharge C-rate, DC bus voltage window, and torque values must be confirmed against the CATL EnerC Installation & Operation Manual, current revision at RFQ stage.
Q4. Which safety and grid standards apply to LFP BESS in Singapore?
Commonly referenced: IEC 62619:2022 (industrial lithium cells), IEC 63056:2020 (BESS DC supply), UL 9540:2020 / UL 9540A:2019 (BESS and thermal runaway), UN 38.3 (UN Manual of Tests and Criteria, ST/SG/AC.10/11/Rev.7), CE/EMC for EU-bound units, and Singapore-specific grid compliance via EMA. Fire-safety scope with SCDF must be confirmed with the appointed Qualified Person.
Q5. What shipping terms does Tradvolt support for Singapore?
Common Incoterms are EXW, FOB, CIF, and DDP Singapore (per ICC Incoterms 2020). State your preference in the RFQ form.

11. LCOS Formula Disclosure
LCOS is defined as PV of costs ÷ lifetime discounted kWh delivered. PV of costs = SGD 2,400,000.00 (Section 2). Lifetime discounted kWh delivered is the sum of Energy (kWh) × Discount factor across years 1–25 of the Section 3 cash-flow table. Because the model's per-kWh charge cost (SGD 0.25/kWh) and per-kWh discharged value (SGD 0.381/kWh) are bounded model assumptions, the headline LCOS of SGD 0.8862/kWh is scenario-dependent and must not be quoted as a sourced fact.
Disclaimer: All numbers in the COMPUTED TABLES are the only financial figures on this page and are computed for the bounded defaults stated in Section 5. Tradvolt does not warrant any specific OEM performance, certification status, or duty outcome until validated by the issuing body and the official Singapore Customs tariff lookup. Replace every PENDING — lookup marker with values confirmed against the named portals before any procurement decision.
