In Southern California on SDG&E, I've been on the
EV-TOU2 rates since the fall of 2013, when we obtained our RAV4 EV. I only had to call them and tell them that I was getting a BEV and would charge at home in order to switch, that and fill out a form with no information to prove it. I didn't really want to do the separate meter, so EV-TOU2 is the plan I'm on. Right now, these are the summer rates:
12PM - 6PM (on peak): $0.46/kWh
12AM - 5AM (super off peak): $0.18/kWh
5AM - 12PM, 6PM - 12AM: $0.21/kWh
For my area, those rates are decent except for the dreaded on peak hours. To offset that, I have had solar panels from SolarCity since the fall of 2015. I paid $0 down for a 20-year lease, and only pay what gets generated from the panels. From SolarCity, I'm paying $0.188/kWh. The nice thing about that my energy usage from SDG&E has been negative during on peak, feeding back into the grid and getting me some payback via net metering.
