My understanding is that there is Tesla VPP fleet wide controller that is instructs each Powerwall how much to discharge and when. Based on comments from past events there is variability from site to site. In 2022 the control software appears to have been mostly brute force and it did dump...

When I originally wrote this, I had picked a couple of low/high points from the graph in the app. Downloading and analyzing the 5 min increment Powerwall data resulted in the following for my two Powerwalls: Date Event Hours Min (5min) Max (5min) Avg 8-28-2023 3 6.4 9.1 7.60...

I don't think we can say "per kwh, this is a better deal", but I do think that it will be a better deal than before as there is no longer the prior day baseline subtraction. The Tesla VPP page says that there will be a maximum of 60 hours of event time. This is lower than the CEC page that says...

If you plan on participating in all events and you expect to be able to discharge at the maximum 5kW rate for the entire event period (up to 2 hours) then your payment would be num_powerwalls * 5 kW * $64.55/kW or num_powerwalls * $322.75. To get to the 5kW rate for the entire 2 hours requires...

There is a bunch more information on this from the California Energy Commission, CEC, which is not the CPUC that I mentioned earlier. For anyone interested you can look here: Demand Side Grid Support Program and you want to focus on "Incentive Option 3" which is the Aggregated Virtual Power...

Oops, I thought something looked odd. It makes it more realistic. I missed that. The same section says that the events are no more than 2 hours and no more than 35 events. Updates in the Tesla app also says no more than 60 hours, but that isn't on the webpage.

Looks like the CPUC, who governs the program, has changed the payment scheme for the 2024 season and it is weirdly not tied to amount of kWh that you provide, but the average kW that you deliver plus a variable rate per month that amounts to$64.55/kW/season. So, if you always consistently...

The right terminology isn't "time of use" it is "Time Based Control". "Time Based Control" is a mode where the algorithm tries to optimize based on basic utility pricing that includes time-of-day and day-of-week pricing to determine when to have the Powerwall start exporting. This works well...

Yes, the baseline is amount per day is tied to the Tier 1 versus Tier 2 rates. This listed on your bill as 9.7 kWh/day and during the February billing period you used an average of 9.77 kWh/day. That amount indicates that you are in "Territory X" and during the summer it increases slightly to...

You are confusing two very different things, one is the utility tariff rate type and the other is the Powerwall operational mode. Time-Of-Use refers to the type of the utility, PG&E, rate plan, which from one of your screenshots is the E-TOU-D plan. This rate plan governs how much you are...

Self-powered means that your house load is powered directly by your self-produced and self-stored power which is either your Solar or your Powerwall. Exporting to the grid and then importing it in the middle of the night is not direct use of your self-produced or self-stored power. Think of...

This should be the same as if you had a HELOC tied to the property, just have it paid off as part of closing.

Similar, $240.80 vs last year at $332.97. I wasn't tracking everything this time around, so no idea if this correlated to the rules or not. I felt dirty having to provide some much details to get the money, bank account (weird that it was account number then the routing number), name, address...

This was discussed over the weekend. You can start here: Tesla Virtual Power Plant in CA Bottom Line - No one has received payment yet, and doesn't look like physical checks this year and payment is via ACH transfer.

The VPP pages at one time said that the payouts were in March, but that has been deleted for the current text. This definitely is not in my app at this time either.

An ACH transfer would require that Tesla has my financial institution's routing number and my account number. Since I have never provided this information, I didn't see how they could possibly do an ACH. Looking into the link above...

The mandate for fluorescent bulb format fixtures versus CFL that screwed into a standard A19 socket was to prevent people/builders from switching back to incandescent after the permit inspections. The rise of LEDs as a lower cost, lower wattage, longer lifetime alternative to CFLs that have...

Global warming is changing environmental conditions and fires will get larger and spread more quickly in drier conditions. These changes aren't just happening in California and to the best of my knowledge, there haven't similar utility originated wildfires in our neighboring states of Oregon...

I grew up in NH with lots of rural customer, lots of trees and nearly every line was overhead and I can't recall any wild fires. I do recall the utility (PSNH then now Eversource) regularly going along and trimming back tree growth every 2-3 years which is the basic maintenance that PG&E wasn't...

And it's broken today. No data available after 1/19/2024 for my account.

Finally! When I went to adjust mine, I noticed there is a complimentary version in the VPP -> Settings section.

Well some of us have SolarEdge HD-Wave inverters which have crapped out. Mine died just shy of the 2 years and it was well after they had supposedly cleaned the pipeline of units that had "faulty" capacitors in them. It was replaced at no cost to me, but since I was still able to buy a 25 year...

In California, the current VPP payment is that you get the regular grid export compensation based on your tariff plan and NEM status and in addition you get $2.00/kWh for the additional kWh your Powerwall/battery discharges during the VPP event versus the average discharge during the same hours...

This was an old post (2 years ago) and I would be very surprised if any Powerwalls are still running that firmware. I wasn't logging all of the firmware updates that were being applied to my Powerwalls until things went sideways with the 22.1.1 release that hit my Powerwalls on 12/16/2021...

I don't get the sound purity obsessiveness of audiophiles, but everyone should have a hobby. I would expect that many that consider themselves true audiophiles would have massive amount of filtering happening between the mains and their equipment to the point where a grid sine wave vs powerwall...

The same cost question (2020 vs now) was brought up then and I addressed in Post 3227 and the equivalent system was $44.2K vs $32.5K. Slightly lower today at $43.0K purchase and $29.7K after tax credit and a minor PG&E credit. The interest rate has gone up since Post 3227 (6.0% vs 7.99%), but...

I've been ignoring the fixed charge by income proposal in the hopes that the legislature will realize that they screwed up and it gets repealed, so I'm not an expert. The basics are that there would be at least three levels of charges and different amounts for SCE, SDG&E and PG&E. The low...

How exactly are you being screwed with your legacy system? <conspiracy_hat on> I am starting to think that a lot of the these news articles and YouTube clips that proclaim the death of rooftop solar because of NEM changes is a FUD campaign run by the utilities to convince homeowners to not...

This is what was authorized. I think I tried to unselect some items, but it complained that it needed them. I don't know why it needs "Vehicle Commands" and I dislike giving them live location data, but this needed to know when the EV is at home.

Only for the E-TOU-C, but I've kept PDFs of the E-TOU-D, EV2 and E-ELEC to reference when I'm interested in something. There are also historical rate Excel sheets here: Rates and Tariffs

Close but it is "only" 23.88% (0.34462 vs 0.27818). The other rate periods have less than an increase which impact the people rate arbitraging with Export Everything and Charge From Grid. At $0.34462 that may change the dynamic for DC fast charging outside of the home versus in-home charging for...

I had a similar experience with the PG&E EV Pulse program which is run by WeaveGrid that needed a Tesla Virtual Key to participate. Made me feel queasy giving them this authorization, but I did it anyway. This is worth $150/year ($50 initial, $75 for the whole year and $25 for end of year...

This is a leap year and February 29th is a day, so yes there is another $0.37612 due. No extra charge for the leap seconds though. 😝

You mean MDC or Minimum Daily Charge which is compromised of all the various unbundled fees. This is currently $0.37612/day, for 365 days that is $137.28.

Thanks for this. Worked for me to resolve the issue.

Grid Charging so that you can Export Everything during Peak for price arbitrage explains the high imports and your negative delivery charge balance.

Wow $521 in NBCs! That's roughly 16,000 kWh of imports. Pre-solar my usage was less than 9,000 kWh.

I have seen bills from a few folks that are undersized and I haven't seen any forecasting happening, just the cumulative year-to-date amounts. The email that you received from PG&E said "Estimated year-to-date Solar energy Charges to be paid at True-Up" has both "Estimated" and "year-to-date"...

Without solar there isn't a NEM policy in place, so you can't price arbitrage by exporting. You can effectively use the price avoidance hoarding practice that you describe with a TOU plan using the Powerwall to power the house during Peak and with anything left during the Partial Peak...

The unbundled distribution/transmission rates (PG&E) and the generation rates (PG&E or CCA) on average are fairly similar. Below is the EV2 rates for PG&E During Peak and Part-Peak, the distribution/transmission rates are higher than generation, and during Off-Peak the lower than generation...

The screenshot from the Blue bill is the generation component from your CCA (Ava Energy was East Bay Community Energy) and that has a NEM balance/credit of $706.09. The screenshot from the B&W bill is for the transmission/distribution component (not sure how it looks for all PG&E) with a NEM...

In your billing for 9/8 through 10/9 the NBCs are almost exactly the same as they should be if the NBC interval was hourly with the rate of $0.03273. There is a small discrepancy of $0.01 between the two periods, but that is probably a weird PG&E rounding issue. Period kWh NBC Cost NBC...

That's crazy, I'm surprised that SolarEdge hasn't investigated further to understand what is causing your multiple failures.

SolarEdge had a lot of issues providing RMA units from 2020 through 2022, but it seems like they have a supply and 2023 replacements have been handled quickly. Hopefully you won't be down for long. As a Tesla Energy customer with a SE inverter I don't expect that Tesla would replace the unit...

The written and approved NEM2.0 regulations take precedent over a web page. I'm not terribly surprised that this discrepancy exists as wording on NBC metered interval does not explicitly say 5 min, 15 min or 60 min. I think it was done this way to allow some variance for existing installed meter...

If you are not using the Powerwall Export Everything option AND not charging the Powerwalls from the grid than you won't hit the export limit. It does appear that you are grid charging, but why are you enabling that feature?

The unpacked/unbundled tariff rate components are more of problem in my opinion than a help, especially in the convoluted way that it is presented on the B&W bill with indeterminate rounding rules. The en It appears that you can do the same math with the bundled rates on the Blue bill to...

The amount of kWh in each TOU bucket is not relevant to understanding your annual true-up amount. The billing info that @holeydonut posted earlier does show kWh per TOU period, so I don't understand why you are saying that you don't have this on your bill. What is relevant are: Net Energy...
