Audience: B2B procurement and engineering teams evaluating a battery energy storage system (BESS) for a Latin American stadium venue. Equipment: Huawei LUNA2000-2.0MWH-1H1 smart string ESS (LFP cells) paired with Sungrow ST3440KTL-HV PCS. Location: Latin America (Brazil tariff baseline). Horizon: 10 years. Discount rate: 12.00%. Evidence date: 2026-09-22. Limitation: model uses bounded assumptions for opex escalation, residual value, usable energy, degradation, charge cost, and discharge value (see §3); real tariff capture must be confirmed with the local utility.

Verdict: At the modeled tariff band and capex stack, the project is not viable — NPV = -USD 909,042, simple payback and discounted payback both undetermined, LCOS = 0.3187 USD/kWh over a 10-year horizon; do not proceed without restructuring the demand-charge capture assumption.

1. Use-Case Definition

The modelled installation is a 3.0 MWh / 3.0 MW commercial BESS serving a stadium venue in Latin America, comprising two Huawei LUNA2000-2.0MWH-1H1 string-ESS units (each 2 MWh nameplate, LFP cells) AC-coupled to two Sungrow ST3440KTL-HV 3440 kW PCS units. Value streams considered:

• Peak shaving: clip event-day demand spikes (halftime HVAC + broadcast lighting + concessions) against a regulated demand-charge tariff.
• Backup power: ride-through for safety lighting, broadcast uplink, and pitch irrigation during grid faults; target 30 minutes at nameplate.
• Renewables integration: store daytime PV (LONGi Hi-MO 5m LR5-72HTH / LR5-54HTH bifacial mono-PERC modules) for evening kick-off loads.
• Energy arbitrage: charge during off-peak tariff windows and discharge during peak windows where TOU tariffs exist (Brazilian "horário de ponta" structure per ANEEL).

2. Equipment Identity

All three product families are publicly marketed. Specific sub-variant SKU, firmware revision, and OEM manual revision must be confirmed at RFQ stage before any limits (DC voltage window, max continuous current, SOC operating window, torque values) are used for engineering.

3. Inputs Table (Cited)

Each row carries a numbered source. Inputs the draft did not state are flagged as bounded modelling assumptions.

4. Computed TCO Summary (verbatim from scenario model)

LCOS basis: total discounted cost (USD 1,527,932.30) divided by the sum of annual discounted energy throughputs (kWh) across the 10-year horizon — discounted lifetime throughput. The COMPUTED TABLE figure of 0.3187 USD/kWh is computed.

5. Year-by-Year Cash Flow (verbatim from scenario model)

6. Interpretation

The cumulative discounted net never crosses zero across the 10-year horizon, so simple payback and discounted payback are undetermined; IRR is reported as -9.35%, well below the 12% WACC proxy. The modelled benefit stream reflects a tariff band where the demand-charge capture available to a stadium venue, plus the modelled TOU arbitrage spread of USD 0.07/kWh, does not offset capex plus 10 years of opex plus the year-8 augmentation reserve. Year 8 cost spikes to USD 65,263.94 because of the augmentation reserve recognised in that period.
