Greenhouse ESS 1 MWh Latam - Use Case & TCO

Verdict (answer-first)

Under the base 10-year, ~1 cycle/day bounded assumption, a ~1 MWh DC-class Li-ion greenhouse BESS in Latin America returns NPV = -436,461.55 USD (PV of costs 630,316.72 USD vs. PV of benefits 193,855.17 USD), discounted payback = None, simple payback = None, IRR = -0.2044, LCOS = 0.3025 USD/kWh. Equipment verdict: Sungrow PowerTitan2.0 ST2752UX liquid-cooled 20-ft container BESS (2,752 kWh stored, 1,500 V DC, operating -30 to 50 °C) paired with the SG3150/4400UD-MV PCS (Sungrow ST2752UX product page); reference product family Sungrow PowerTitan2.0. Location: Latam (jurisdiction TBD at RFQ). Horizon: 10 yr base. Discount rate: 10.00 %. Evidence date: 2026-09-22. Limitation: financial figures are computed from a single bounded tariff blend and a single demand-charge assumption; substitute the site-specific tariff and demand-charge before commitment. The financial verdict must be re-issued against the chosen OEM's datasheet and the manual revision cited at RFQ; operating limits (DC voltage window, SOC window, lug torque, max C-rate) are not asserted on this page until that manual is bound.

The financial verdict at the bounded defaults is negative; do not commit capex on bill savings alone without substituting site-specific tariffs and the chosen OEM's datasheet values. The bound OEM equipment verdict is the Sungrow ST2752UX; operating limits (DC voltage window, SOC window, lug torque, max C-rate) must be re-asserted against the OEM's installation and operation manual (revision captured at RFQ).

1. Context

A ~1 MWh DC-class lithium-ion battery energy storage system (BESS) sized for a mid-to-large Latin American greenhouse complex can shave demand peaks, ride through grid instability, and back up ventilation and irrigation during outages. This use-case page reports the bill-savings arithmetic and the total cost of ownership (TCO) envelope computed by Tradvolt's scenario TCO model so a procurement or sustainability lead can shortlist a configuration before opening a formal RFQ. The financial figures in §5 are computed and are reproduced verbatim from the model output; no other financial numbers appear on this page.

2. Inputs

Inputs labelled "Assumption: explicit bounded default" or "Model assumption" are model inputs stated for traceability, not sourced facts; they must be replaced by named tariff lines, OEM datasheet values, and site measurements before any commitment.

3. Equipment verdict (bound OEM model)

The financial verdict is bound to the Sungrow PowerTitan2.0 ST2752UX liquid-cooled 20-ft container BESS paired with the SG3150/4400UD-MV PCS. Public product page: Sungrow ST2752UX product page. Product family page: Sungrow PowerTitan2.0.

Publicly published limits taken from the product page above (current at evidence date 2026-09-22): stored energy 2,752 kWh; DC bus 1,500 V; operating ambient -30 to 50 °C; container format 20-ft liquid-cooled; pairing PCS family SG3150/4400UD-MV. Per-product power, duration, and cycle-life figures are not published on the ST2752UX product page and must be asserted against the OEM's installation and operation manual (manual title, edition, revision captured at RFQ); operating limits not on the public product page - DC voltage window, SOC window, lug torque, max C-rate - are not asserted on this page until that manual revision is bound.

Candidate alternates in the same ~1 MWh DC turnkey class (each a named, publicly marketed product; sub-model, manual title, and revision to be confirmed at RFQ):

• CATL EnerC - 1 MWh container-class DC BESS. OEM reference: CATL energy storage. Specific sub-model (e.g., EnerC 20-ft container) and manual revision confirmed at RFQ.
• Huawei Smart String ESS (container class). OEM reference: Huawei FusionSolar. Specific sub-model and manual revision confirmed at RFQ.
• BYD MC Cube / HVS-class commercial-industrial LFP (residential/CI rating band; cabinet ratings must be confirmed against the OEM datasheet before any utility-scale claim). OEM reference: BYD Energy Storage. Cabinet rating and manual revision confirmed at RFQ.
• EVE Energy prismatic LFP cells (cell-level OEM, typically integrated by a pack/system partner). OEM reference: EVE Energy. Cell part number and pack-integration manual revision confirmed at RFQ.

4. Methodology (one paragraph)

The scenario TCO model integrates Capex, annual Opex (%/yr of capex), a mid-life augmentation allowance (% of capex, incurred at the listed year), and a benefit stream (annual energy-value USD plus annual demand-charge USD), all discounted at the stated rate. The base benefit stream is the single number reproduced in the COMPUTED TABLE §5 as "Benefit (USD)"; the 0.18 USD/kWh blend and 110 USD/kW-yr demand tariff are the bounded defaults behind that stream, with the ESS charge cost already embedded in that blend (charge cost per kWh = 0.00 USD/kWh as an explicit bounded default) and residual value set to 0 USD at no terminal year. The COMPUTED TABLES in §5 are the only mathematics on the page.

5. COMPUTED TABLES (verbatim from scenario model)

Closed-form NPV check (sum of discounted net cash flows): (-550,000.00) + 23,373.52 + 20,550.95 + 18,056.14 + 15,851.88 + 13,905.14 + 12,186.58 + 10,670.17 + (-16,325.13) + 8,153.90 + 7,115.31 = -436,461.55 USD, matching the NPV line in the TCO summary table above. A procurement professional can re-verify the NPV by summing the "Discounted net (USD)" column of the year-by-year cash-flow table without trusting the model.

Headline LCOS is computed as the 10-year PV of costs (630,316.72 USD) divided by the discounted kWh stream over the same horizon; LCOS = 0.3025 USD/kWh.

6. HS code block with lookup instructions

How to confirm HS classification and duty rate: (1) Pick the candidate row that best describes each line item (cells vs. PCS vs. BMS/switchgear). (2) Pull the current national tariff schedule from the destination country's customs authority. (3) Cross-check with the latest WTO or regional trade-agreement schedule the country is a party to (Pacific Alliance, Mercosur, EU agreements) for any preferential rate. (4) Confirm the ruling with a licensed customs broker in the destination country before shipping.

Disclaimer: No duty rate is asserted as fact on this page; every duty figure is marked PENDING and must be confirmed by a licensed customs broker against the current tariff schedule of the destination country.

7. Certification and shipping standards (informational)

Final certification set is site-specific and must be confirmed with the local authority having jurisdiction (AHJ) and the chosen EPC. The IEC, UL, UN, and IATA references above are the canonical sources; cite the full designation, edition, and revision against the OEM manual and the chosen OEM at RFQ.
