Well, as it turns out, I have some decent news from PG&E. The wording says that for the purposes of grandfathering, PG&E is to use the
earliest PTO on the current tariff. Because installing Powerwalls in May of 2018 required them moving me to NEM2 (NEM-PS), that PTO is the earliest on my current tariff and will be used for grandfather purposes.
More importantly, I was told that for most residences with similar storage (one to two Powerwalls), EV2-A is not an eligible rate anyway, and those on EV-A
will not be moved. I asked if this was across the board for storage, and he said it was not, but that it would pretty widely apply. He suggested that those with storage on the EV-A rate plan should call ASAP to clarify. I called the PG&E number provided by
@miimura (877-743-4112).
@MikeW, I see you're a long time member but an infrequent poster so I'm not sure if you are frequently lurking. If so, I wonder if the bolded text in my original paragraph would apply to you since you've been moved to NEM2 already. Perhaps because you moved after the rate plan was approved it does not apply. And you didn't mention storage, so I'm not sure if you have that protection or not.
I definitely suggest that those with storage give PG&E a call. I'm good until November 2023..
