Maybe, but I'm not convinced. The document that you linked to is draft version and the text is for A.1 Non-residential while the VPP is under A.4 rules. It does say hourly, but it isn't clear to me if that is hour-by-hour comparison or using hourly increments versus 5 or 15 minute increments. Further confusing the issue is the latest CPUC ELRP documents make reference to "adopted baseline methodology" and "(IIOUs) shall have discretion to determine the proper baseline against which Incremental Load Reductions will be calculated".

Tesla Virtual Power Plant in CA
- Thread starter power.saver

Hour-by-hour is the way it used to work a few years ago when I was a member of OhmConnect. I think it likely that they haven't changed. The 10 weekday and 4 weekend day lookback periods are the same as back then, for example. It should be easy for me to tell at the end of this season if we keep having long VPP events like today's.
I thought I read somewhere in the 50+ pages of this thread, that people who participated in VPP last year essentially got the amount they exported during VPP x dollar / kWH as payment back in March. All this nebulous calculation by the power companies really seems unnecessary as they will always err on the side that benefits them most.
A couple users said that this was how their payment worked out, but I think that for the majority, including myself, the numbers didn't work that way. IMHO, the problem is the lack of reporting from Tesla on the payment. No breakdown of any kind from them, just a check.
I might give this a try…but with 51.3kWh normally available, at 11.8kW sustained, that is 4.35hrs to get to 5% reserve. So if I start at 4p I’ll be at 820p anyway, really only 40min to delay.
Also, yesterday I had excess SoC at 9p, but now I’m off peak rate. So export credits weren’t as good.
So now thinking this through as I type, I’ll leave it at 5% reserve. Then from 4p to whenever they calculate I “typically” stop exporting…if they discredit that for VPP, at least I get peak credits.
That is correct from the way it was worded. However, a bunch of us got paid simply by the total amount exported seemingly without any deduction for the typical amount exported. Additionally, we got full credit for peak time export as well. It really was double dipping.
Thought about but was slightly paranoid it might be seen as an opt out. Maybe someone can try it and report back
This would be great if they don’t really use the baseline. At least since I’m exporting every day from 4p usually until about 730-8p
I set it to 99%…will set it to 0% at 430p. Then will put it back to 5% after today.Thought about but was slightly paranoid it might be seen as an opt out. Maybe someone can try it and report back
That said, didn’t CAISO indicate tomorrow is another impacted day? So maybe one more VPP to follow?
So I'm not convinced this will make a difference. Say you discharge 10kwh from 4 to 5 pm. If your solar generation is the same as yesterday, you'll get $20 towards vpp. If you export 0 because you set your reserve to 100%, then you'll get $0 because he 5 or 6 kwh (or whatever it is based on your installation) will be typical and you won't get credit for it. So if you delay exporting until 8 pm when you're making little or no solar, you'll still get $20 for that same 10kwh.
To really game the system, you kinda need to go into self consumption during the solar export period that overlaps with the event times days before a series of events so that you can lower your average export or even eliminate it if your home usage is high enough during that period.....and then to extra game it, make sure you turn everything off during the event.
Another VPP event on old (23.4.2-2) Powerwall firmware... another event where my batteries are not discharging into grid even though the Tesla app says "Powerwall is discharging to support the grid". Well yeah, they are discharging, but only into my home loads.
Best part? Tesla support told me today it would take them 3-4 weeks to look at pushing a FW update to my system

Just note that while it would make sense for all of these various Demand Response / VPP (both terms now used generically) programs to work the same way, they are not all governed by the same rules. OhmConnect is not part of ELRP that Tesla VPP is; I think OhmConnect is categorized as a third-party Demand Response Provider (DRP), that participates by way of a successful bid in the Demand Response Auction Mechanism (DRAM), it is different from being part of ELRP, and has been around longer.
From the end-user standpoint, they probably look similar in how each residential consumer's participation is measured, probably by design. But one clear constant in ELRP is the end-user gets $2/kwh (even though folks are not 100% sure how kwh are measured). Whereas third-party DRP's I believe define their own incentive structures in how they compensate end-users to entice enrollment - could be flat annual incentive, could be hourly, could be whatever. Ohmconnect is definitely not $2/kwh like ELRP, but it is typically $1-1.40/kwh (but sometimes with 2-4X multipliers, and other incentives.
How much do you all think you'll get this year from participating in the VPP? I mean in terms of $ in your wallet/purse; not some higher NEM credit from your peak time exports.
My check was $538 for last year but I was late signing up and missed 4 or 5 events.
From a warranty perspective, does participating in VPP exclude unlimited warranty coverage for pushing stored energy to the Grid (as in VPP events)?? Where can you see aggregate throughput? Is that the sum of lifetime Discharged / Charged for the power wall in the app? If so, I'm already at 21.7MWh for my 2 year old system.
