Just thought I would mention that Alabama Power discounts residential rate by $0.017155 per kWh for 9pm to 5am for charging. That's nearly 15% off at night. You have to give them documentation (title application, etc) that you bought an electric vehicle or phev. They check again every year or so for current tag registration in order for you to keep the lower rate. Other utilities may have programs that are similar so I thought I'd mention it. None of the dealers ever tell anyone here when they buy.
