I'm reviving this old thread because I updated the my spreadsheet rate calculator to reflect all the changes that happened at PG&E in 2016. Here is a little summary of the changes that I noticed.
1. New rate plans E-TOU-A and E-TOU-B were implemented starting March 1, 2016. They are not good for EV owners. From what I can tell, for most people they are approximately the same as E-1 but with some penalty for using power from 3-8pm or 4-9pm. They also have their own unique Summer duration and E-TOU-A has its own baseline quantities.
2. E-9 disappeared from the rate tables as of March 1, 2016
3. E-7 disappeared from the rate tables as of January 1, 2017.
4. Tiered rates changed from 5 bands to 3 bands starting August 1, 2016. They are now Baseline, 101%-200%, and over 200%. There used to be tiers at 130% and over 300%.
5. There were 7 different rate periods in effect during 2016, the shortest period was March 1, 2016 to March 23, 2016.
Minimum Charges are nothing new, but they were increased in 2015 for all rate plans to over $10/month and as of March 2016 there is a new Minimum Energy Charges table on NEM statements. I have now accounted for this in my calculations but not rigorously compared it to my NEM statement because a bunch of my Green Button data is not available right now. If your energy charges are higher than the minimum, there is no adjustment, if you are positive, but below the minimum, you are charged the minimum, if you are negative due to self generation, the minimum charge is added to your negative energy charge, decreasing your true-up credit.
All the historical rates for at least 2015 and 2016 are included in the Bill Calculation tab. You can copy and paste the whole blue shaded table for the period of interest to the top of the page and it will be used in the active calculations.
If you find any mistakes in the spreadsheet, please let me know.

I have been reading up on NEM 2.0 and thinking about how to calculate correct NEM charges with it. I will start a new thread for that in either the California sub-forum or the Energy, Environment & Policy sub-forum.
