Just a heads up that San Diego Gas & Electric has an new EV rate. This one has a $16 monthly charge in exchange for .09/kWh super off peak rates - and a very slight savings on the other time periods.
This is probably better than EV-TOU-2 if you don't have PV. As it only takes 115 kWh of super off peak power each month to come out ahead.
If you have PV, then you will have to do a bit of work to figure out if it works out or not since the $16 monthly charge isn't part of NET metering and doesn't buy you any energy (it isn't a minimum charge). So under the new tariff, you will pay $192/year before you pay for any energy versus paying $120/year for $120 worth of energy.
Also, if you are on grandfathered TOU time periods, you will lose that status if you switch. This rate only has the 4-9pm peak rate on the tariff - no grandfathered time periods. It may still be a better deal if you use a lot of super off peak power and have low usage in the evenings - this will need to also be weighed against the super off peak going into the afternoons on weekends (not good for PV credits).
