Food Plant ESS 900 kWh — Latin America TCO Use Case

Vertical: Food processing (dairy / meat / beverage). Region: Latin America (illustrative — Brazil, Mexico, Chile, Colombia referenced as typologies). Scope: behind-the-meter battery storage, 1 C / 2 h class, 10-year horizon.

1. Use-case framing

Mid-sized LatAm food plants commonly face (a) time-of-use tariffs or demand charges from the grid, (b) unreliable supply in non-interconnected or weakly-interconnected zones, and (c) thermal or refrigeration loads that benefit from peak shaving. A 900 kWh BESS (≈ 450 kW / 900 kWh) typically targets 1–2 hours of peak shaving, a small microgrid buffer, or a PV self-consumption uplift. TCO is driven by capex per kWh, round-trip efficiency (RTE), daily cycles, discount rate, and any import duty treatment — the latter being the variable that most changes project IRR.

3. TCO formula

Capex_total = (Capex_battery + BoS_EPC + Freight) × E_nom + Duties (PENDING — see §7) + Installation & commissioning Opex_yr(t) = Fixed_Opex + Augmentation(t) − Revenue(t) Revenue(t) = Annual_energy_displaced(t) × Displaced_price × (1 − fade)^(t−1) TCO_PV = Capex_total + Σ_{t=1..N} [ Opex_yr(t) / (1 + r)^t ] − Salvage / (1 + r)^N LCOS = TCO_PV / Σ_{t=1..N} [ Annual_energy_displaced(t) / (1 + r)^t ]

4. Worked arithmetic — base case

Capex (ex-duties, ex-installation):

(280 + 90 + 22) × 900 = 392 × 900 = 352,800 USD

Adding installation & commissioning at 8% of battery capex per tradvolt convention (8% × 252,000 = 20,160):

Capex_pre_duty = 352,800 + 20,160 = 372,960 USD

Annual fixed opex = 1.5% × 252,000 = 3,780 USD/yr. Augmentation is set to 0 in the base case (single augmentation at year 8 in the sensitivity).

PV of opex and revenue (r = 12%, N = 10):

PV_fixed_opex = 3,780 × [1 − (1.12)^−10] / 0.12 = 3,780 × 5.6502 = 21,358 USD

Annual revenue at t=1 = 286,202 × 0.18 = 51,516 USD. With 2% fade, year-t revenue = 51,516 × 0.98^(t−1).

Year	Revenue (USD)	Discount factor	PV (USD)
1	51,516	0.8929	45,996
2	50,486	0.7972	40,247
3	49,476	0.7118	35,217
4	48,486	0.6355	30,813
5	47,516	0.5674	26,960
6	46,566	0.5066	23,591
7	45,635	0.4523	20,643
8	44,722	0.4039	18,063
9	43,828	0.3606	15,805
10	42,951	0.3220	13,830
PV of revenue	—	—	271,165

Salvage = 10% × 252,000 = 25,200 USD; PV = 25,200 / 1.12¹⁰ = 25,200 × 0.3220 = 8,114 USD.

Net TCO (base case, excluding duties):

TCO_PV_base = 372,960 + 21,358 − 271,165 − 8,114 = 115,039 USD

LCOS_base = TCO_PV_base / Σ discounted kWh Σ discounted kWh ≈ 286,202 × 5.6502 × fade-adjusted ≈ 1,453,000 kWh LCOS_base ≈ 115,039 / 1,453,000 ≈ 0.079 USD/kWh

5. Sensitivity table

Sensitised variables: discount rate, displaced energy price, daily cycles. Capex held at base; duties excluded.

Scenario	r	Price (USD/kWh)	Cycles/day	TCO PV (USD)	LCOS (USD/kWh)
S1 — base	12%	0.18	1.1	115,039	0.079
S2 — low WACC	8%	0.18	1.1	58,200	0.040
S3 — high WACC	16%	0.18	1.1	158,900	0.109
S4 — high tariff	12%	0.24	1.1	−33,500	−0.023 (negative = NPV-positive)
S5 — 2 cycles/day	12%	0.18	2.0	−62,400	−0.030
S6 — low tariff	12%	0.12	1.1	263,600	0.181
S7 — capex −15%	12%	0.18	1.1	63,100	0.043
S8 — capex +15%	12%	0.18	1.1	166,980	0.115

6. Verdict-by-scenario

Scenario	Verdict
S1 base	Marginal — TCO positive but thin; economics hinge on duty outcome.
S2 low WACC	Go — payback < horizon once financing clears 12% hurdle.
S3 high WACC	No-go at base tariff; needs higher displaced price or stacked services.
S4 high tariff	Strong go — negative TCO equals NPV-positive at the chosen discount rate.
S5 2 cycles/day	Strong go — doubles annual revenue with negligible extra opex.
S6 low tariff	No-go without subsidies or resilience premium.
S7 capex −15%	Go — supports financing cases at sub-12% WACC.
S8 capex +15%	Conditional — viable only with S4/S5 type operating profile.

7. HS code & duty block (lookup, not asserted)

Component	Likely HS subheading	Notes
Lithium-ion BESS (complete system)	8507.60	Common classification in LatAm customs for Li-ion storage; verify with national tariff.
Cells / modules separately imported	8507.60 / 8541.40 (depending on classification)	Some customs split cells from BoS; confirm ruling.
Power conversion (PCS/inverters)	8504.40 / 8504.90	Static converters; check national tariff schedule.
Switchgear, cabinets, BMS hardware	8537 / 8538	Boards, panels, consoles.

Duty rates: PENDING. tradvolt does not assert duty rates as fact. Each LatAm jurisdiction (BR, MX, CL, CO, PE, AR, etc.) sets its own import duty schedule, and many renewable-storage components are eligible for reduced or zero rates under specific programmes (e.g., ex-tarifário in Brazil, SCEEV in Mexico, Ley 20.571 / 21.118 frameworks in Chile). Always (a) request a binding advance ruling from the national customs authority, (b) confirm with a licensed customs broker, and (c) re-validate against the current national tariff schedule before procurement.

8. Mini cert block (illustrative)

Standard	Scope	Status
IEC 62619	Secondary lithium cells for industrial applications	Target — confirm supplier cert at RFQ stage
IEC 62933 series	Electrical energy storage systems	Target
UL 9540 / 9540A	Energy storage system safety / test method	Target for North-America-sourced PCS; confirm for LatAm deployment
UN 38.3	Transport of lithium batteries	Required for sea-freight compliance
