wanted to bump this thread.
PGE introduced new E-TOU-D plan and according to them i would save more if i switch from EV-2A to E-TOU-D. its not that i trust PGE. Has anyone done analysis & compared prices?
Here is pricing for each reate: https://www.pge.com/pge_global/comm...-work/Residential-Rates-Plan-Pricing-2020.pdf

$30 difference is about 20-25% of your annual bill, which seems like a big % difference. But you have both large generation (as indicated by the big negative summer months) and large consumption (as indicated by the winter bills) in terms of kwh. While they won't likely change the TOU structure of either, any of their slight tweaking of the hourly per-kwh charge could easily swing that $30 difference in either direction.
Here's my dumb experience - with solar (no powerwalls) and EV's, I was around $120 net annual true-up, and I saw a slight advantage on the order of $20-30/yr of (now discontinued) EV-A over my grandfathered E-6, which had a few good years left before phasing out. Since EV-A was closing to new customers, I made the switch knowing I couldn't switch back to E-6. In short order, PG&E not only closed EV-A, they discontinued it, forcing everyone to EV2-A or E-TOU-A, then removed E-TOU-A, forcing those users to E-TOU-C or E-TOU-D. I lost out on $200-300/year, had I stayed on E-6, to try to save $20-30.
I believe they will keep messing with E-TOU-X variants until it is as disadvantageous as possible, especially with millions of E-1 customers being forced to them over the next year. While there is no guarantee of EV2-A, there are going to be far less customers on it for them to bother mucking with new varaiants such as EV3-A, EV4-A as frequently. So if I were you, I'd stay on EV2-A and hold out for something more substantial than $30/year savings, as there's no guarantee that E-TOU-D will be around a year from now. and a replacement is likely to not be in your favor...
