Off-Peak EV Charging in 2026: The Time-of-Use Trick That Halves Your Bill

By Sarah Mitchell2026-04-207 min read

Most utilities with EV rates charge a low overnight price and a high daytime price. Shifting your charging to the 11pm–6am window commonly cuts the bill about in half — often the single biggest EV saving after the car itself.

Key takeaways

  • TOU EV rates split the day into cheap overnight and pricey daytime tiers.
  • Charging 11pm–6am often cuts cost roughly in half.
  • Enroll the day you plug in — do not wait for the first bill.
  • A smart charger or schedule timer automates the shift.
  • Savings beat most public-charging and gas comparisons.

How a TOU plan actually works

A time-of-use (TOU) plan prices electricity by the hour. EVs are perfect for it because you can shift a predictable overnight charge into the cheapest block. Typical EV TOU windows run roughly 11pm to 6am at 10–18¢ per kWh, jumping to 25–40¢ during the day. If your utility offers it, enrolling is usually free and the savings land on every future bill.

The saving, in real numbers

Utility (example)OvernightDaytimeAnnual @12k mi
CA IOU EV rate~$0.13~$0.40~$520 vs ~$1,200
TX repriced~$0.11~$0.22~$440 vs ~$880
NE utility~$0.16~$0.38~$640 vs ~$1,520

Automating the shift

Pro tip

A $300–$500 smart charger or even the car’s built-in schedule can hold charging to the overnight window automatically. Set it once and the savings happen whether you remember or not. Pair it with the 30C charger credit if you installed before July 1, 2026.

The mistake that erases the saving

The trap is plugging in the moment you get home at 6pm and letting the car top off during the expensive evening block. One forgetful night a week can add 20–30% to your annual cost. A simple schedule timer — most EVs have one in the infotainment — fixes it for free. Estimate your yearly bill with our <a href="/calculators/ev-charging-cost/">EV charging cost calculator</a>.

When TOU is not worth it

If you cannot charge at home — apartment, street parking, no outlet — TOU does nothing for you, and public fast charging at 35–50¢ per kWh plus fees will not beat gas in a high-rate state. TOU only pays when the car sits plugged in overnight on your own meter.

Frequently asked questions

What is off-peak EV charging?+
It means charging during the utility’s cheap overnight window (often 11pm–6am) on a time-of-use rate. The per-kWh price can be less than half the daytime rate, which is where the saving comes from.
How much can off-peak charging save?+
Commonly about half the charging bill. A California driver at ~$0.40 daytime vs ~$0.13 overnight cuts a 12,000-mile year from ~$1,200 to ~$520 — a $680 annual save for setting a timer.
Do I need a special charger for TOU?+
No. Most EVs have a charge-schedule feature in the car; a smart charger adds automation and sometimes utility rebates, but the free in-car timer is enough to capture the savings.
What if I forget and charge during the day?+
You pay the high tier for that session. One slip a week adds 20–30% to annual cost, so automate it with the car’s schedule so you never have to remember.
Is off-peak charging better than public stations?+
For daily use, yes — home off-peak at 10–18¢ beats public DC fast charging at 35–50¢ plus fees. Public makes sense for trips, not the commute. Model it with our <a href="/calculators/ev-charging-cost/">charging cost calculator</a>.
