Use case / Total Cost of Ownership • tradvolt.com • Evidence date 2026-09-22 • Limitation: illustrative; site-specific tariffs, demand-charge structures and duty rates must be re-verified by the importer.
Answer / decision: For the computed base case (300 kWh / 150 kW commercial LFP BESS, MEA 24/7 call center, 10-year horizon, 9.00 % discount), the 10-year NPV is −188,449.18 USD (negative NPV = net economic cost; benefits do not repay capex + opex at the modeled tariff and demand-charge assumptions). Simple payback: none within horizon. Discounted payback: none within horizon. LCOS: 0.3362 USD/kWh. Verdict for the base scenario: NOT justified on energy arbitrage + demand-charge savings alone; the modeled kWh tariff (0.14 USD/kWh), demand charge (18 USD/kW/mo) and cycle throughput are insufficient to recover capex at a 9 % WACC over 10 years. The system remains potentially justified only if non-modeled revenue lines (UPS ride-through value, second-life residual, demand-response payments, PV self-consumption uplift) are priced separately.

Note on the year-10 line: the negative Cost of −20,444.25 USD reflects the modeled residual-value credit returned to the buyer at end-of-horizon (RV = 15 % of C₀). The undiscounted residual at year 10 = 24,750 USD; PV of the residual is captured via the discounted net column across the horizon. Do not re-derive.
NPV = −188,449.18 USD means the discounted costs exceed the discounted benefits by ~188k USD over 10 years at a 9 % WACC. Simple payback and discounted payback are not reached within the 10-year horizon because the cumulative discounted net remains negative throughout (year 10 discounted net is +8,036.81 USD but the cumulative discounted net from year 0 through year 9 is deeply negative; the model reports no payback year). LCOS of 0.3362 USD/kWh is therefore higher than the modeled 0.14 USD/kWh kWh tariff, confirming that energy-arbitrage value alone does not repay the asset at the modeled duty cycle. The base verdict is: NOT justified on the two revenue streams modeled (energy displacement + demand-charge savings). The asset may still be justified on unmodeled lines (UPS ride-through, second-life residual uplift beyond 15 %, demand-response payments, PV self-consumption uplift), which must be priced separately and added to the COMPUTED TABLES' Benefit column.
The COMPUTED TABLES are run against a generic 300 kWh / 150 kW commercial LFP class. For procurement, the buyer should validate a specific OEM rack system against the §1 inputs. The following are real, publicly marketed product families whose datasheets and product pages exist at the URLs shown; tradvolt does not assert certification for the modeled generic 300 kWh class — see §5.
