Frequently asked questions

It depends on the gap between your flat rate and your off-peak rate, how many miles you drive, and how much of your charging you can shift to off-peak hours. Drivers on a time-of-use plan who charge mostly overnight often cut their charging cost meaningfully, since off-peak rates can be a fraction of the daytime rate.
