computed TCO / landed-cost model output. Equipment: Sungrow IDC120E. Origin: China. Destination: Georgia. Horizon: 25 years. Discount rate: 8.00%. Evidence date: 2026-09-21. Limitation: figures reflect the bounded scenario inputs disclosed in §10; binding landed-cost quotes re-validate HS/duty/VAT against rs.ge on the RFQ award date.
Verdict: USD 1,371,368.03 NPV · simple payback 0.4801 year · discounted payback 0.5185 year · TCO per km USD 0.0542 (EV charging equipment share) vs USD 0.2055 (displaced ICE) · savings per km USD 0.1513 · net cash benefit over 25 years USD 3,782,500.00 (undiscounted).
For a Sungrow IDC120E (120 kW DC, CCS2 / ISO 15118) shipped CN → Georgia for highway-service fleet duty, the scenario model with the bounded inputs in §11 returns a strongly positive NPV at an 8.00% discount rate, with payback well inside year one. The EV-side equipment TCO is roughly one-quarter of the displaced ICE TCO on a per-kilometre basis. Recommended next step: submit an RFQ via /rfq/ to receive a binding landed-cost quote that re-validates HS 8504.40 duty and Georgian VAT against the official Georgia Revenue Service tariff portal.

Figures are computed model output from the scenario TCO model. All currency in USD. Horizon and discount rate as stated above. The energy column in the year-by-year cash-flow table is reported as 0.0000 kWh because the scenario's benefit stream is annualised as a flat USD 139,900/yr operating benefit (energy throughput and gross margin are embedded in that benefit, not separately metered at the equipment).
The product modelled here is the Sungrow IDC120E — a publicly marketed 120 kW DC fast charger from Sungrow Power Supply Co., Ltd. The IDC120E is the 120 kW member of Sungrow's IDC series of integrated DC fast chargers designed for highway-service and high-utilisation sites.

Under the bounded scenario in §3 (25-year horizon, 8.00% discount rate), simple payback is 0.4801 year and discounted payback is 0.5185 year, with NPV of USD 1,371,368.03. Results vary with utilization, electricity tariff, and RFQ-confirmed landed CapEx.
HS 8504.40 (static converters) is the indicative national line; accessories may classify under 8537 or 8544.42. Re-validate against the Georgia Revenue Service portal (https://www.rs.ge/Home-en) on the RFQ award date, with cross-checks against EU TARIC and USITC HTS.

The values below are the bounded assumptions the scenario TCO model used. They are model assumptions, not observed market prices. They are reproduced here so a reviewer can reproduce the figures in §2–§3. No additional bounded defaults were used beyond what is listed here.

Energy column in §3 is 0.0000 kWh because the benefit stream is annualised as USD 139,900/yr (energy throughput and gross margin are embedded in that figure, consistent with §11 inputs). TCO per km in §2 derives from the EV-fleet and ICE-fleet inputs above (10 vehicles × 100,000 km/yr × 25 years = 25,000,000 fleet-km horizon). Per-km figures are reported rounded as the scenario model output them (TCO/km EV 0.0542, ICE 0.2055, savings 0.1513).
