Just got my Bill for sep charges, so according to the statement, I was also moved to E6 rate without any notice.

And guess what I also got in the mail today , a letter from PG&E stating that based on my energy usage I would be transferred on over to the E6 rate(recommended) as of August 1, 2015. Funny thing, when I look up at my energy usage on their website, it actually states that I would save most by using the EV rate.
So by default, I assumed that since I was in the E9 rate that once that was finished. I would be eventually transferred into the new EV rate, so imagine my surprise that I wasn't and on top of that my bill is a bit higher than usual. Called them to voice my opinion and also request retro pay.
So keep an eye out on your PG&e bill to make sure that you are in the new EV rate and not some other one that they recommend so they can gouge you on it.
