Do you think the plan really saves any money? Have you ever found it necessary to charge outside of the off-peak hours , especially on the weekends which because those rates are significantly higher than just the standard rates it might eat into any savings from the normal charging at off-peak times
I switched to the EV+Home plan when I got my car and my electricity bills before and after stayed the same, even with daily charging. My house is heated with gas (although the winter peak rate is only slightly above the nominal rate) and I have a Nest thermostat set up so that the AC only occasionally kicks in at the tail end of the summer peak-rate times. So for the other ~18 hours a day, my electricity rate is below the standard rate.
I can only recall two instances in the past two years where I've needed to charge at home in the middle of the day, so the plan has been a net-win for me. I am concerned that Dominion has curtailed signups and the EV+Home plan will, IIRC, sunset in 2018. I'm hoping that Dominion and whichever VA utility board regulates electricity rates will renew this plan or offer a substantially similar one in the future.
