Low Electricity Rate
Many states are offering a super low night rate for electricity used at the night times. Please check with your local utility company. Sometimes you also have to put a request in with the cooperation commision to instates these rates.
For example in Arizona we do have a super low night rate (2 cent/kW) for EV owners from APS. If you are with APS you can apply the EV owner super low rate 2.2 cent per KW from 11 PM to 5 AM at night. For this purpose please contact aps.com
You would need to have a copy of our electric bill and the registration of your car submitted per e-mail.
