I was able to find a SCE Rate Comparison Tool mentioned by Boomer23 at breakfast last Saturday. It supposedly allows you to evaluate and compare several of the new and old TOU rates against your actual usage for the previous 12 months. Of course if you are contemplating adding solar or another EV, this evaluation will be flawed, but if your usage is stable, it should help a lot.
There are several paths on the web site to this tool. One is: home (residential) -> rates are changing -> learn more -> Residential Rate Plans -> Rate Comparison Tool.
I say "supposedly" because I could not run the tool. It requires a customer account of the form: 3-###-####-##. My customer account has the form: 2-##-###-####, so the tool rejects it. Is this because I am already on TOU-D-A ? I believe others on this thread also have TOU-D-A. Do you also have a 2-## account ?
I am overwhelmed with all the TOU choices, but some of them can be eliminated right away if you have solar, because they price daytime at Off-peak or Super Off peak (TOU-D-4-9PM, TOU-D-5-8PM).
