I spent some time looking into electricity providers who offer discounts for night EV charging. All of the switching websites seem to be a bit behind the times as none ask you if you have an EV...
I spoke with my current provider (Pulse) an they said that in order to offer a night rate, I would need a second meter. I have a smart meter and I thought that the whole point of smart meter was to enable real-time monitoring.
Thus far, it seems that Mercury is the most proactive in offering an EV plan.
What do you use?
