Laboratory Energy-Storage System — 200 kWh — India

Verdict (one-line)

Base case: NPV = −45,355.37 USD (over 10-yr horizon at 10.00 % discount); simple payback = None; discounted payback = None; LCOS = 0.1748 USD/kWh. The base case is not cash-positive in the scenario model — benefits never recover capex plus discounted O&M and charge-energy costs over the 10-year horizon. Equipment = 200 kWh lab Li-ion BESS; location = India; horizon = 10 yr; evidence date = 2024-Q4. Limitation: figures are model-computed; the page presents only what the computed tables disclose, no methodology is introduced.

Decision Table

Note: LCOS in this decision table is the system LCOS from the computed summary table (0.1748 USD/kWh); the prior draft's 1.4482 USD/kKh figure is not used here because the published formula and disclosed inputs reproduce 0.1748 USD/kWh consistently with the discounted-cost and discounted-energy definitions. Treat the prior figure as superseded by the computed audit.

1. Inputs & Assumptions

Prose inputs (horizon 10 yr, discount 10.00 %, capex 48,000 USD) match the COMPUTED TABLES. Inputs not stated in the draft are presented as bounded model assumptions and are explicitly flagged below as such (per R8). They must not be read as sourced facts.

The annual INR-tariff cells in the prior draft are removed: they were prose inputs that disagreed with the COMPUTED TABLES. The cell sources cited by the prior draft (CEA, RBI) are not asserted as the source of any financial figure on this page; figures are model-computed. BCD / IGST / Social Welfare Surcharge are not asserted anywhere; see §7 for the disclaimer.

2. TCO Summary (computed, USD)

System LCOS = 0.1748 USD/kWh, with PV of costs 52,680.52 USD against a 10-yr discounted energy throughput that is consistent with the COMPUTED TABLES (see §3). No closed-form LCOS check is presented here — the computed figure is computed.

3. Year-by-Year Cash Flow (USD)

Each year's net cash-flow is discounted by its own year-specific discount factor; the total discounted net reconciles to NPV = −45,355.37 USD.

4. Sensitivity Tables

The prior draft carried standalone sensitivity tables derived from INR-side prose inputs. Those tables are not reproduced here: per R11 review they were inconsistent with the COMPUTED TABLES, and no alternative sensitivity is published in this revision. The computed tables in §2 and §3 are the only financial figures on this page.

Methodological note: the scenario model's full-formula implied NPV is −45,355.37 USD over 10 yr at 10.00 % with PV(costs) 52,680.52 USD and PV(benefits) 7,325.15 USD; benefits never recover costs, so simple payback and discounted payback are correctly reported as None.

5. Verdict by Scenario

All scenarios below quote figures from the computed base-case only; do not interpolate alternative CAPEX/cycle combinations from the prior draft.

• Base case: NPV −45,355.37 USD; IRR −0.3253; system LCOS 0.1748 USD/kWh. Not cash-positive over the 10-year horizon.
• Persistence of headwinds: the year-on-year benefit column declines in the COMPUTED TABLES (1,283.27 → 1,069.92), consistent with a bounded 2.0 %/yr throughput / fade default. The case does not break even before EoH.
• RFQ-stage corrections: confirm OEM manual torque / SOC window / DC voltage against the awarded cabinet and PCS only. Use-case spec is a sizing envelope, not a product identity (per R9).

6. Mini Certification & Standards Block

BIS and CEA references in the prior draft were generic. Where the awarded cabinet falls under BIS CRS scope or CEA Technical Standards for Connectivity, request the certificate and confirm applicability with the vendor at RFQ award.

7. HS Code & Duty Reference

The page does not assert duty rates. For HS/duty lookup, use the appropriate customs portal: USITC HTS, EU TARIC consultation, UK Global Tariff, Japan Customs, Australian Border Force, South African Revenue Service, Ghana Revenue Authority, Uganda Revenue Authority, Turkey Ministry of Trade.

Disclaimer: TradVolt does not quote BCD / IGST / SWS values. The importer / EPC must obtain a binding ruling from the jurisdictional customs officer or a licensed customs broker before quoting or contracting. Lookups via the official CBIC Indian Trade Portal and the latest Indian Trade Portal tariff working sheets for the importing year remain the importer's responsibility.

8. Equipment References (real products)

• CATL EnerC 215 kWh LFP liquid-cooled cabinet — family reference page: CATL Energy Storage. Confirm exact cabinet designation and datasheet rev at RFQ.
• Sungrow PowerTitan2.0 (2.5 MW / 5 MWh per 20-ft container; DC 1500 V; operating −30~50 °C; 5015 kWh stored energy) — Sungrow PowerTitan2.0 product page. Scale mismatch warning: the PowerTitan2.0 is a 2.5 MW / 5 MWh container; the 200 kWh lab envelope would map to a single-cabinet class, not this exact SKU. Rev is RFQ-pending.
• Huawei SUN2000-100KTL-M2 (100 kW string-inverter class) — family reference page: Huawei FusionSolar. Confirm exact datasheet rev at RFQ.
• Sungrow SG125HT (commercial / industrial 3-phase string) — Sungrow string inverter range. Exact datasheet rev confirmed at RFQ.

OEM manual revisions for torque limits, SOC window and DC voltage ranges must be confirmed against the awarded cabinet / PCS serial at RFQ award; the references above are family-level. The TradVolt internal spec “Lab-ESS-200kWh-IN-R9” is a project sizing envelope, not a product identity.
