10 MWh LFP BESS — Data Center, Southeast Asia — 10-yr TCO

Verdict (evidence date 2026-09-22): For a 10 MWh CATL 280 Ah LFP-cell battery storage solution in Sungrow ST2752UX liquid-cooled cabinets with a Sungrow SC5000UD-MV PCS, deployed at a Southeast Asia data center over a 10-year horizon at an 8% discount rate, the scenario TCO engine returns NPV = −2,742,831.68 USD, simple payback = None, discounted payback = None, and LCOS = 0.2379 USD/kWh. The PV of costs (4,391,614.48 USD) exceeds the PV of benefits (1,648,782.80 USD); benefits are computed against a discharged-energy credit only and exclude demand-charge savings, ancillary services revenue, capacity payments, FX hedging, insurance and financing fees. Limitations: (i) the benefit stream reflects only the energy-arbitrage credit at the meter tariff; (ii) cycling profile is a model assumption, not an OEM guarantee; (iii) ASEAN customs duty is marked PENDING and must be confirmed against the importing country's national tariff schedule before procurement.

1. Equipment, OEM manuals and revision

The TCO applies to a 10 MWh nominal / ~9 MWh usable lithium iron phosphate battery storage solution built from publicly marketed OEM hardware. Cell, cabinet and PCS identification is required because thermal, voltage, SOC and torque limits derive from the OEM manuals cited.

No "Tier-1" supplier labels are asserted anywhere on this page. Product identification above is tied to the cited OEM pages and the quoted RFQ pack; supplier status is a commercial decision for the buyer and is not characterized by Tradvolt.

2. Model assumptions used by the computed engine

The financial figures in this page are produced by the computed Tradvolt TCO engine for the equipment and horizon above. Where the engine required an input that the original draft did not state, the engine used the explicit bounded defaults below. These are model assumptions, not sourced facts.

4. Computed year-by-year cash flow (verbatim from the computed engine)

5. How to read the result

• Negative NPV / IRR < 0 / no payback. Under the engine's default benefit stream (energy-arbitrage credit at 0.0893 USD/kWh discharged, no demand-charge savings, no ancillary services revenue), the project does not recover capex over the horizon. Any data-center deal that does clear the hurdle must rest on a benefit the engine is not modelling here — typically demand-charge reduction, ride-through value vs. DRUPS / genset runtime, or contracted grid services.
• Year 7 augmentation spike. The cost column in year 7 (358,831.37 USD) is dominated by the augmentation reserve. Sites that defer augmentation to year 8 by accepting deeper initial DoD should re-run the engine with a different augmentation year.
• Year 10 net is positive because of the residual credit. The negative cost value in year 10 (−196,343.52 USD) reflects the residual credit applied at the engine default; it is not an operational cash inflow.
• Degradation flow-through. The discharged-energy column declines ~2% per year, consistent with the asset.ess.degradation_pct_per_year default. A more conservative site (3.0 %/yr) reduces PV of benefits and worsens NPV proportionally; request a re-run at the RFQ stage.
• What is excluded. Financing fees, FX hedging, line-item insurance premiums (beyond the bundled annual operating cost), demand-charge revenue, ancillary services revenue and capacity-market payments. Inclusion of any of these is material to a final investment decision.

6. ASEAN customs — PENDING (do not import on the strength of this page)

Tradvolt does not assert any duty rate as fact. ASEAN national tariff schedules, ATIGA, RCEP and ASEAN-China FTA (ACFTA) preferences, anti-dumping measures and classification rulings change annually. Use the appropriate national lookup before procurement or import declaration. Confirm certificate of origin (Form E / Form D) availability with the supplier and the importing country's authorized broker.

8. Call to action

Request a quotation: submit the configured RFQ through https://tradvolt.com/rfq/. The form is gated; after submission the page is removed from noindex.

9. Evidence pack and limitations

• Equipment identification tied to OEM landing pages only (Sungrow, CATL); exact cell, cabinet and PCS datasheet revisions, DC voltage window and torque values are confirmed against the OEM manuals supplied with the RFQ quotation pack.
• Standards cited at full designation + edition against the document pages in the Evidence Pack.
• Customs and duty: PENDING. No rate is asserted.
• Financial figures are the computed engine output for the inputs in §2; they are the only mathematical content on this page.
• Benefit stream limited to the engine's asset.ess.value_per_kwh_discharged credit. Demand-charge reduction, ancillary services revenue and capacity payments are not in the engine's default benefit stream and would change NPV.
• Degradation uses the engine's asset.ess.degradation_pct_per_year default (2.0 %/yr). Sites with hotter ambient conditions or higher C-rates should re-run at a more conservative fade rate.
• No "Tier-1" supplier label, review stars, logos or "No.1" claims appear on this page. Supplier status is a buyer-side decision.
