    My original PV system dates back to 11/2015. I have been on NEM 1.0 and TOU-D-A since that time.

    2/2020: added 2 Powerwalls, remained on NEM 1.0 + TOU-D-A
    2/2021: added 15 more solar panels and 1 Powerwall; currently in PTO process

    My question is, would I be able to keep NEM 1.0 once I receive PTO this time around? Or would I be forced onto NEM 2.0? I realize 2.0 is not that terrible, but just wanted to see if others in the community had experience or knowledge on this.

    As a side note, I expect to lose TOU-D-A and be forced onto one of the newer TOU rate plans any day now.

    Your going to be forced onto NEM 2.0. If your system size changes more than 10% or 1kW I believe is what it says. You can basically fix a panel, but adding is going to force you onto NEM 2.0

    He is talking about Southern California Edison, not PG&E.

    So they are different? Oh well. I sure would have thought twice about losing NEM1

    The NEM rules appear to be the same, but their TOU rate schedules are different.

    I think you can get a 2nd meter and have both the old system on nem 1 and new on nem 2 but cost will be likely be more than just paying your 2-3c nbc especially if your 3 powerwalls allow you to have low grid usage

    Thanks for all the input. Will probably just transition the entire system to NEM 2.0 as suggested. Definitely going to miss that sweet TOU-D-A rate plan though.
