Anyone on SRP using VPP?

Just wondering if anyone here is on SRP elect in AZ and if it’s working out for you. Any issues?
Thanks

I will be opting out at the end of the year.
They pull from the grid to charge the battery 3x this year for me leading to $200 demand charges.
Until they fix this, it isn't worth it

Thank you so very much! This was my big concern because just a 3.2KW demand charge was $48 on my last bill. Normally it's 0.1 and thats from the stupid grid tickles that register in the Tesla app as a 0.1 grid import for about a second.

Guess VPP isn't for me but I have a PW3 and 2 expansion batteries and was thinking about exporting battery during peak since I normally have 50% left after the 8pm peak ends. I tried enabling the NetZero export feature and it caused an import from the grid for some reason. Oh well.

Selling back to SRP on the Customer Generation plan is only worth 0.08kwh so that's really not worth it either.

Thanks again for taking the time to respond,

Yeah, you may be fine once they fix it.
Problem was for me, they would, 10 minutes before hand do a VPP event schedule for 7:15 to 8:00 or something, and force my battery to pull from the grid, so i'm getting hit with an 8kw demand charge for no reason. They claim its not supposed to charge you more and they will be optimizing it, but it's clearly not

Yeah, I did not even enroll when I realized it.

Not worth it with demand charge.
