Back in December we opted out of the SD rate study because SDGE wanted to add a second meter to our system for the car. We have an excess of solar power since we designed the system for two electric cars. SDGE wanted us to pay for charging the car even though we were producing plenty of power from our PV system. We reviewed all the rate schedules before we made the decision and back then there was only two different classes, M and H, the low rate structure not currently being offered. (Though in reality the L,M,H names I found highly misleading once you study the rates. They are posted somewhere on SDGE's site. They are buried pretty deep otherwise I'd link to them)
We'll see how the rest of the EV Project goes now that the car has been delivered!
