Interpolated between $50M, $200M, $500M breakpoints
We tested 472K, 945K, and 2.36M EVs. Optimal station placement doesn't change — the best locations are the best locations regardless of fleet size. What changes is utilization and queue times. The planning question is budget and focus, not headcount.
Data: 9 scenarios (3 budgets × 3 focus types) from real Texas AFDC, Census, TxDOT AADT, and HIFLD substation data. 472,572 registered EVs, 3,976 existing stations, 4,151 substations. Cost model: hardware $150K/port, installation $50K/port, land $200K/station, grid upgrades at $55.38/kW. O&M: $6,500/port/year, NPV at 5% over 10 years.
