Method — effective $/kWh (energy + demand + fixed charges per published schedule) from RightSite’s 5/10/15% load-factor model, interpolated linearly in 1/LF to each state’s implied energy load factor: observed statewide fast-charging time-utilization × 0.45 average-power factor, clamped to 2.5–15%. AK, MT, ND, SD, VT and ME sit at the clamp floor — true economics there are worse than shown. Statewide averages; individual sites vary widely.
Territories — HIFLD Electric Retail Service Territories (2025 federal archive), cleaned; multi-state utilities clipped to the tariff’s state; overlaps draw smallest-on-top; where two ranked schedules share a territory the better-ranked colors it.
Utilization — Paren, “State of the Industry: US EV Fast Charging,” Q2 2026, average DCFC utilization by state.
