So I finally switched to SoCal Edison's TOU-D-TEV this month. They even sent out a service technician to verify my wiring.. not sure why but he opened up my panel the part where SCE has there security cable tag on it. He just looked at the service entrance wiring, put the cover back and retagged my panel. He was genuinely interested in the Tesla and knew quite a bit of facts about it already. So I had the old rates in my Excel spreadsheet and I wanted to verify the summer/winter transition and saw the new rates listed, effective April 1, 2013 linked here I hope these aren't typos. I tried to get a more descriptive breakout on the generation/delivery charges in a PDF file, but they seem to be referencing the old rates. If these are true, I'm a truly happy camper. With our second Model S coming soon (hopefully), that's 9 or 10cents a kWh basically every day, all year long Tier 1 or Tier 2 for the super-off-peak periods.
