A lot of my fellow electric vehicle owning friends often talk about how their EV charging is "free" through their power companies EV special rates and policies. The notorious ones are the 9pm - midnight free power period and the EV special rates. I must note that different plans can suit different households, and I'm sure that for some households, these plans work out, but in my analysis, the plans that offer "free" or heavily discounted rates usually have much higher day rates.
For me, the cost of the Genesis EV plan was nearly $500 more than my current standard Mercury rate (with 9pm - 7am half price).
