I forget the date, but if you got solar in the past, and are on NEM1, you get 20 years, so no tou change I believe
Grandfathering for NEM tariffs, NBCs, and process is 20 years.
This means someone who is on NEM 1.0 and paying that $2.00 per month NBC or whatever will keep paying that for many years even after NEM 2.0 or NEM 3.0 come in (assuming AB1139 doesn't pass).
Grandfathering for TOU structures (not the $ per kWh; just the fundamental structure) is 5 years.
This means someone on NEM 1.0 but with the E-6 TOU had 5 years of benefit before they will be forced to switch to E-TOU-C or EV2. That is why @astrob made this thread. The grandfathering they had on the EV plan is ending so they're being pushed to EV2.
There is no grandfathering for TOU $ per tier/structure/time-slot.
This means someone on NEM 1.0 but EV2-B was hit with that recent increase that brought Summer Peak up to $0.56 per kWh. And presumably this will go up again once PG&E is authorized to increase their "revenue" again to match their crazy cost base.
Edit: And I hope it's not lost by now that I view the TOU gamesmanship as the true way PG&E makes its "fair share" from people. I know the prevailing common knowledge from just a few years ago was that PG&E paid for the fair share of residential solar by using NBCs and interconnection fees. But to me, messing with TOU is where they can force someone to pay more $ even if hey were grandfathered into the old NEM. And of course AB1139 would just kick that messy Jenga puzzle over and force everyone with rooftop solar into one big bucket without any of the grandfathering on NEM or TOU carrying over. That's why I hope more people write their local reps.
