Verdict: NPV = -AED 5,070,169 over 10 years at 8.00% discount; simple payback = None; discounted payback = None. TCO per km: EV = AED 0.1888 vs ICE = AED 0.3160; savings per km = AED 0.1273; savings over horizon = AED 2,545,000. Horizon: 10 years. Equipment: 50-port AC EVSE array (Sungrow AC011E-01 reference charger, GoodWe HCA-G1 series equivalent). Location: UAE office tower. Evidence date: 2026-09-27. Limitation: 10-year discount horizon; OPEX escalates at 2% p.a.; 80% utilization applied to BOTH energy cost and revenue consistently per R11.
