Yep, going through this now with my change to the battery plan. If I have too much, I will invite neighbors over to charge their EV's for free

Tesla Virtual Power Plant in CA

That's not on Elon, I think. That's part of the deal if you accepted the federal subsidy. You gotta take that one up with the government.
Edit: I couldn't find my source for this. Might be regulated by PUC.

I am only a little bit surprised. I mentioned earlier in this thread I would be surprised if it was much more than NEM credits + a small payment of < $100 per year per powerwall or something. I am surprised there is not some token payment of $50-60 a powerwall + nem credits, but I was fairly comfortable that there was no way they were actually going to "pay something" that would be worth it.
The benefit is as I mentioned earlier:
The benefit is as I mentioned earlier:
No it is not!!! Some of use did not get ITC wict SGIP! And the rules say we can charge from the grid, they will just only keep their head in the sand.
My opinion on what should happen with this is, people who are getting powerwalls "for free" through SGIP should "have" to participate in this and any other "help the grid" program that is rolled out, since "california" is paying for their storage, not them. I am aware that this would likely not be the position you would have, though.
I just edited my post to say I think it might be PUC. Either way, that's just Tesla following regulations but I agree that the rules are wonky. I think that VPP is a whole new ballgame and rules should be adjusted.
Tesla is now letting Powerwall owners enroll, and the website also got an update! Join the Tesla Virtual Power Plant | Tesla Support
I would fully support this is I can grid charge!! Sign me up
PUC support grid charging! I copied all the stuff from the sites, PGE also, sent to Tesla and they blew me off.
If all of that A/C usage that is draining those Powerwalls is during Peak already, then you wouldn't benefit at all from enrolling (assuming you don't want to go below 15%), and the public good for your participation would be low to zero.
If some of that A/C usage is during Part Peak, then enrolling would cause you to be a net exporter of ESS energy during the events, which would reimburse you at the higher NEM rate of Peak, presumably curtailing your Part-Peak on-site ESS offset and increasing your Part-Peak grid usage. So you'd make pennies on that arbitrage, but it would also be a public good.

I’m willing to bet Tesla DOES want to. Since they do that with other utilities in the US and around the globe. I bet it’s your CA utility that is dragging their feet preventing that from happening.ELRP is $1,000/MWh. Why can't Tesla get on board with something at the CPUC and get us half that amount - $0.50/kWh???
With tou-c, I think there is no part peak. But either way, I do from 3pm on, and need 100% of it for my AC keeping my big house at 72
Now the house batteries do not get drain as much, so some flexibility there.
Has to be a give and take. Give me ability to grid charge, which I need in winter, approve my 30KW of solar, and game on, we can work together.
And if you want to help pay for some more batteries, lets light the place up
Knowing something about the CPUC, there is a heavy, burdensome process to to me make rate changes along the lines of what we would like to see - 6 months to a year or two.
Taking this on as a public good helps us out now for this summer and essentially becomes a pilot test for the concept. Maybe they only get one in ten powerwall owners, but that s enough to show value and test the concept out. Later, incentives may appear after a full process through the CPUC.
So, I'm also going to try this out. Doesn't look like it will affect my financials to any significant degree, and I'm good with helping my community, even at a minor cost.

I suppose it depends on how you're using your powerwall. I don't think there's much of a change if you are already spending power back to the grid as part of an NEM agreement.
In my case, the plan was to use a battery during peak hours where rates are highest ($0.56) so from 4-9pm.
I guess a concern is if I'm set to send up to 50% of the powerwall energy during 4-9pm and it hits 50% at 6pm, then that means I'm now having to go to the grid for power (at the highest rates) or start draining the batteries earlier and may not have enough to last the last 3 hours of peak rates and less during a grid shutdown.
Everyone is looking out for their own interest, why not? I enrolled, to me it is more for the common good if it does not hurt me. If I get the notification and see that my 2 PWs can get me through the night and the weather forecast tells me the sun would come up the next day then I am fine, if not, I can always turn it off.
