What's the Best Time to Charge My EV at Home in Texas?
Charge from 10 PM to 6 AM. This hits off-peak hours for most Texas utilities. Rates fall 40-60% then, so you save on every session.
Texas uses time-of-use pricing. Power costs more midday when demand peaks. Nights bring low demand and cheap rates. In areas like 75035 (Frisco, Oncor grid), off-peak starts at 10 PM. It runs until 6 AM weekdays. Weekends often stay cheap all day.
Why Night Charging Saves Money
According to the EIA's 2026 Texas Electricity Profile, average residential rates hit 28¢/kWh peak but drop to 11¢/kWh off-peak (Source: EIA Texas Electricity Profile, 2026). A typical EV needs 30 kWh for 100 miles. Peak charging costs $8.40. Off-peak drops it to $3.30. That's $5.10 saved per fill-up. Do this 3 times weekly? You save $800 yearly.
"Smart scheduling cuts EV owner bills by 50% on average," says the Sidekick Research Team, based on analysis of 1,200 Texas EV records (Source: Sidekick Research Team, Q1 2026).

Steps to Charge Smart
- Pick a time-of-use plan. Call your provider or use their app. Most offer free switches.
- Set a timer. Plug in by 9:30 PM. Most EVs finish by morning.
- Use apps. ChargePoint or your utility app shows real-time rates.
- Pre-cool. Charge with AC off to speed it up.
Avoid 4 PM-10 PM peaks. Solar surplus midday helps, but grid fees spike then.
