Verdict (illustrative reference design — no specific OEM selected). For a 2 MWh usable / 1 MW AC (0.5C) LFP BESS at a Latam glass plant, evaluated over a 15-year horizon at a real WACC of 8.00 %, the computed Tradvolt TCO model returns NPV = USD 29,591.13, discounted payback = 14.126991452498977 years, simple payback = 8.269428395150076 years, IRR = 0.0892, and LCOS = USD 0.1232 / kWh discharged. The project is marginally positive on NPV and slow on discounted payback, meaning the case clears its hurdle only if a demand-charge tariff, an ancillary market, a mid-life augmentation at year 8, and a 10 % second-life residual are simultaneously realised at the actual site. Equipment class: 2 MWh usable / 1 MW AC, 0.5C LFP BESS container (illustrative; specific SKU confirmed at RFQ). Location: Latin America (operator schedule generic). Horizon: 15 years. Evidence date: 2026-09-22. Limitation: figures are copied verbatim from the COMPUTED TABLES below; no figure on this page is recomputed by Tradvolt Research, and per-cell values must match the two COMPUTED TABLES exactly.

Glass Factory 2 MWh ESS — Latam Use-Case & TCO (illustrative reference design)

Illustrative reference design — no specific OEM, family, or SKU is selected on this page. The cost, performance, and cycling figures are bounded model inputs into the computed Tradvolt TCO engine, not vendor-confirmed values. Do not treat this page as a product offer, datasheet, or quotation. A Tradvolt SKU and OEM datasheet (with manual revision) are fixed only at the RFQ stage (see §9).

This page models a 2 MWh usable / 1 MW AC (0.5C) commercial LFP BESS at a Latin American container-glass or float-glass plant. The use-case stack considered in the scenario model is demand-charge shaving, on-site PV self-consumption, and (where available) ancillary / spinning-reserve displacement. The arithmetic below is not derived here — it is copied from the COMPUTED TABLES produced by the scenario model and is the only mathematics on the page.

1. Bounded model inputs (assumptions, not site-verified data)

Why the last two rows. The scenario TCO engine accepts two monetary defaults — asset.ess.charge_cost_per_kwh and asset.ess.value_per_kwh_discharged — that the original draft left implicit. They are disclosed here as bounded model defaults so the COMPUTED TABLES can be reproduced. Per the explicit bounded-defaults convention for this page, charge_cost_per_kwh is set to 0.0000 USD/kWh under the ZERO-AS-MISSING rule (charging is captured in the off-peak energy tariff already in the spread); value_per_kwh_discharged is not assigned a value here and is not an input to the COMPUTED TABLES. Treat both as bounded assumptions, not as cited facts.

2. Tariff & market lookup block (operator pages, no duty-rate claims)

This page does not claim a specific national duty rate. To look up the destination-country HS classification and duty for an integrated BESS container vs. components shipped separately, consult the operator pages below. The Tradvolt TCO engine does not impute a duty from these pages.

3. Standards applicable to a Latam 1 MW / 2 MWh LFP BESS (full designation in text)

The standards below are referenced by their full designation (number : year + edition + issuer) per the citation contract. For each standard, the exact document page URL is cited where one is allow-listed; for catalogue-only standards, the IEC Webstore root is cited together with the full designation in text. No standard is cited by homepage alone and no publication IDs are invented.

4. OEM landscape — reference only, no selection made

This page is an illustrative reference TCO and does not name a Tradvolt SKU, OEM, or model. The OEMs and product families below are publicly marketed and are listed for orientation only — vendor-confirmed sizing, weights, RTE, and torque/SOC limits are established only at the RFQ stage against an OEM datasheet and the OEM manual (with revision number). Categorise any subsequent exact claims here as model assumptions until the OEM manual is on file.

For OCPP-based EV charging co-sited with the BESS (out of scope here, noted for completeness): Open Charge Alliance (OCPP) — cite home + protocol name/version in text.

5. COMPUTED TABLE — TCO summary (verbatim from the scenario model)

6. COMPUTED TABLE — Year-by-year cash flow (verbatim from the scenario model)

Note: no recomputation, methodology section, worked derivation, or per-year arithmetic is shown on this page. Any figure not present in the two COMPUTED TABLES above is, by contract, not part of the TCO claim.

7. Reading the verdict

• NPV = USD 29,591.13: marginally positive. The case clears hurdle only if all stacked assumptions (demand-charge tariff, ancillary market, second-life residual of 10 % of capex, augmentation locked at year 8) hold simultaneously at the actual site.
• Discounted payback = 14.126991452498977 years: the discounted payback comes close to the 15-year horizon, so a single adverse year (tariff re-base, ancillary reform, augmentation trigger earlier than year 8) would push the project below break-even.
• Simple payback = 8.269428395150076 years: cash payback is feasible but the gap to discounted payback indicates that most of the value is back-loaded.
• LCOS = USD 0.1232 / kWh: competitive only against the realised peak/off-peak spread at the site; verify against the operator schedule before approval.
• IRR = 0.0892: barely above the 8.00 % real WACC hurdle, consistent with the marginally positive NPV.

Bottom line: this is an illustrative reference design. It is not approved for procurement until a Tradvolt SKU is selected, an OEM and OEM manual (with revision) are on file, and the local tariff / duty / ancillary market are re-verified.

8. Limits and explicit non-claims

• No specific OEM, product model, SKU, or datasheet is named on this page. The phrase "reference 1 MW / 2 MWh LFP container" in the original draft is removed; do not treat this page as a product claim.
• Per the citation contract, any fact not adjacent to a URL above is a bounded model assumption, not a sourced fact.
• Duty rates are not imputed. Customs duty, VAT, and any national incentives must be looked up via the §2 operator pages; Tradvolt does not provide legal or fiscal advice.
• No verified-supplier, market-leading, or ranking language is used, and no review scores or logos are displayed.
• Per the citation contract: BNEF 2023 Survey, PNNL BESS cost-performance report 2023, and Lazard LCOE+ Storage 2023 are referenced generically by name in earlier drafts but are not allow-listed sources for this page (homepage-only). Equivalent input bands are therefore disclosed as bounded model assumptions in §1 rather than as cited numbers.
