Cheapest Charging Hour Map

When home charging is cheapest across 14 major US metros — built from each utility’s published EV time-of-use rate. Pick your city; the map shows every hour of the day, colored by price tier, with a marker on the hour it is right now in that city.

The rule of thumb: plug in after 9 PM–midnight, let it finish before the early-afternoon peak, and never charge 4–9 PM. That single habit beats almost every “smart” charger setting.
Cheapest (super off-peak) Off-peak Mid / partial-peak Peak — avoid Real-time priced Flat rate (no penalty) Rebate-eligible

How to read this. Each row is a metro and its main residential EV rate; colors mark how the price changes by hour. Overnight is cheapest almost everywhere — the green blocks are your window. Honest exceptions are baked in: Chicago (ComEd) is real-time hourly pricing, so overnight is only statistically cheapest; Seattle is flat-rate, so charge whenever; Boston is a managed-charging rebate, not a TOU rate; and Dallas/Houston “free nights” still bill delivery (~5–6¢/kWh).

Verified off-peak prices where available: Georgia Power Overnight Advantage 2.19¢/kWh (cheapest here), Xcel Minnesota EV Accelerate 3.8¢/kWh, FPL EV pilot 2.016¢/kWh, PG&E EV2-A ~23¢ off-peak vs ~54¢ peak; Con Edison SmartCharge pays a 10¢/kWh overnight rebate. Windows are from each utility’s published EV/TOU rate (2025–2026). Audience geography: Google Analytics 4, last 28 days.
