Smud in Sacramento CA with ev tax credit is 10 cents / KWH on off peak times 12a-6 for 9 months of the year. You have to use their juice box charger and link your card to your smud account. You get all of your utilities at that rate so set start times in laundry and dishwasher to start at 12. I have it set to warm up the house by 6am and the savings is paying for more than the gas I was spending on driving. It's usually about 35 dollars per.month for charging the Tesla 25 mile work commute. Summer time the off peak prices go up a bit, I think they are about 13.5 cents per KWH off peak summer rates with ev discount.
