The Money-Saving Answer
Charge between 11 PM and 7 AM on Time-of-Use plans to save 50-70%. Off-peak rates average $0.08-0.12/kWh versus $0.25-0.40/kWh during peak hours. This saves $40-80 per month for typical drivers.
Understanding Time-of-Use (TOU) Rates
Most utilities charge different rates based on when you use electricity. Peak hours (when everyone uses power) cost more. Off-peak hours (late night/early morning) cost less.

How to Set Up Scheduled Charging
Tesla makes it easy to automatically charge during off-peak hours. Here's how to set it up:
Open Tesla app
Tap your car, then tap the charging icon at the bottom of the screen.
Enable scheduled charging
Tap "Schedule" and toggle on "Scheduled Departure" or "Scheduled Charging." Choose the time you want your car ready (e.g., 7 AM).
Set off-peak times
Under "Off-Peak Hours," enter your utility's off-peak window (typically 11 PM - 7 AM). The car will only charge during these hours.
Plug in anytime
Now you can plug in whenever you get home. The car won't start charging until your scheduled off-peak time.
Pro tip: Use "Scheduled Departure" instead of "Scheduled Charging" to also precondition your battery and cabin, ensuring maximum range and comfort.
Special EV Utility Plans
Many utilities offer special rates for EV owners with even bigger savings. Call your utility and ask about these programs:
EV-specific Time-of-Use plans
Super-low overnight rates ($0.07-0.10/kWh) designed for EV charging. Available from PG&E, SCE, SDG&E, and many others.
Whole-home TOU plans
Lower rates for all electricity during off-peak hours, not just EV charging. Good if you can shift other usage too.
Separate EV meter
Some utilities install a second meter just for your EV charger with special low rates. Requires electrician installation.
Demand response programs
Get paid to reduce charging during peak events. Programs like OhmConnect can earn you $50-200/year.
