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...

Circling back around to this at the end of the year (2023). The NSC rates continue to drop across the board after the large increases in early 2023. Utility Dec 2022 True-Up Dec 2023 True-Up Peak PG&E 0.05878 0.06941 May'23 - 0.08788 SCE 0.05119 0.05881 Apr'23 - 0.07778 SDGE...

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...

Circling back to this thread, the snippets that you posted are from a bill that covers your true-up month. How do these bill sections look for a "normal" month? Reviewing these again, I think that these are the expected format for a solar account without ESS and a CCA (SJCE) for generation.

@YRide Did post details of their Blue bill and you replied to that post :) There is a bunch of information there, but some of the context is missing in how the individual images are assembled together. I think it would be best to take this discussion to that thread.

The B&W bill is only for accounts with ESS. Based on your posting history you do have Powerwalls. If you aren't getting the paper version have you looked for it online? Care to post your extended content blue bill info?

I can't think of any reason why these be would be different. Please post screenshots of the issues that you are seeing.

There is an image angle to these credits with the CPUC positioning this as relief coming from them to make up for higher prices. Having a single amount given to every account helps out lower income households to a larger extent than higher income households. If this was rolled into rates then...

The California Climate Credit applies against any charges that you have. The October PG&E credit was $38.39 which covered my September and October MDCs and gas charges and I still have a $4.34 credit that will apply to my November bill. I would caution against wording this as reducing your...

Under NEM2.0 the MDC/MEC are paid each month, so at my October true-up the only thing that I paid was the last month of MDCs which brought the total for the 12 months to $133.72. My PG&E net energy charges for the year was -$608.16, but that doesn't matter for this discussion. If I had...

You need to scratch your head a bit more, as you are still incorrect. Your solar array will generate X kWh per year, your house consumes Y kWh per year and recharging your EV consumes Z kWh per year. Your NSC check will be (X - Y - Z) * rate. Please notice that there are no TOU considerations...

I'm 99% sure that with solar that is all you get. The screen shots with Power, Grid and House are all using the Tesla Gateway that disconnects the house from the grid to provide those other measurements.

Well this is basically what I wrote except for the "exported kWh are credited at NSC rate". Your net annual kWh are compensated/paid at the NSC rate (or higher with a CCA) when the accumulated retail credits/charges for exports/imports are below $0. Your math here is faulty as it is comparing...

This isn't the way that NEM2.0 works, but it is close to how NEM3.0 works. Under NEM2.0, the exports get a credit at the retail rate, so if the export was during Off-Peak it would be the same as the Off-Peak import and the $0.25 export credit offsets the $0.25 import charge. If the export was...

This isn't correct. If you export 1kWh and import 1kW then your net is 0 kWh which means your NSC is $0.00 and you have a NBC of $0.0328.

I don't think that would really work. Maybe you could set a really high import price and a $0.00 export price from 10:00-14:00, but that won't do anything about leaving room in Powerwalls to recharge from excess that they house doesn't use during that time What is really needed is a setting...

The graph says Home = 0% and 0kWh Vehicle = 41% and 7.8 kWh Powerwall = 38% and 7.4 kWh Grid = 21% and 3.8 kWh Seems like you have a problem with how your system is measuring home usage.

Agreed that 4% is low, but that is what I recall him saying he used in his model and in the end that is a conservative number. I used 10% in my prior posts on NEM 3.0 payback modeling.

The near $2/kW in the summer of 2020 and the pending ITC reduction from 26% to 22% (this didn't actually happen as Biden/Congress increased the credit) at the end of 2020 was what got me off the fence and into solar. I didn't know nearly enough about how NEM2.0 worked, but I knew that was a...

I was talking with a neighbor that is in the process of getting solar installed (Tesla, 10KW Panels, 2 Powerwalls) with a tentative installation date of Feb 2024. He has run the numbers for his usage and operating as self-powered and has concluded that his payback will be at 8 years under NEM3.0...

Looks to me that if you put panels on that porch roof they are likely to be in the shade most of the day/year.

I am in the "gently use it" camp as I don't need to deeply discharge my Powerwalls for Peak/Off-Peak NEM price arbitraging. I have mine set to 85% during the Summer period and 92% during the Winter period. I do this partly to help out the grid during the Peak periods, partly to get some higher...

The percentage that you see in the app is not the actual charge percentage remaining in Powerwall. At 0% there is still 5% charge remaining, so there is nothing to worry about.

You don't "owe" SCE anything, it is just an adjustment to reflect the actual retail price of the kWh for this tariff that looks really weird when you are on NEM 2.0 and exporting more than you are using. SCE, and PG&E, breaks out the credit for below the baseline usage as separate line item...

I was checking the PG&E Green Button data download today and it is working again with no missing data for me.

A VPP event would pre-charge the battery if the Powerwall software didn't think that it would get 100% before the start time from just solar. Since there isn't a VPP event today the VPP specific software function won't pre-charge the battery from the grid and it is a normal charging cycle...

There was a wide range ($100-$500) in the reported check payments from Tesla. I think the likely average was around $225, so for PG&E that would be only $1.35M. So, yes a drop in the bucket. I hate getting emails like that from PG&E. It is going to be higher, but we can't tell you how high.

Ok, so you don't have 20+ hours, but 20+ kWh which is a different thing. :) Your days match the days in the table I posted earlier, but those days had a total of 16 hours and with 4 hours for today it gets to the VPP minimum of 20 hours.

What days and time did you record as VPP events?

Discussion already had up-thread: Tesla Virtual Power Plant in CA (this is the start).

I went back through this thread and verified in the Tesla app Powerwall tab. It looks like the event today will bring us to the 20 hour VPP program minimum. Date Start End Duration 7/20 8:15 9:00 0:45 7/25 7:45 9:00 1:15 7/26 6:00 9:00 3:00 8/28 6:00 9:00 3:00 8/29 4:00 9:00 5:00...

The VPP event is today (9/19) from 5-9pm, the announcement was yesterday (9/18)

The compensation rates have gone up a lot over the last couple of years from the original NEM 2.0 literature that said 2-3 cents/kWh. PG&E's rate for true-up in April 2023 was $0.08478/kWh and my CCA, SVCE, doubles this, so I received $0.16956/kWh for my excess which is higher than the average...

For PG&E it is just the annual net import kWh multiplied by the Net Surplus Compensation rate list in the AB920 document you posted for the month of your annual true-up. That was likely me, as I am with a CCA, Silicon Valley Clean Energy, and they pay at twice the PG&E NSC rate. Other CCAs...

You have two 7.8kW inverters, so if PV is split that is 10.2kW of PV per inverter or ratio of 1.31. Depending on the orientation of the panels it might not make sense for these to be 50/50. You might have more panels that are facing North going into one inverter and less panels facing South...

You aren't seeing this term, because it is generally known as oversizing the PV array versus the inverter. The inverter will not do more than its rated spec, but you can put more kW into than it can output.

I can confirm that this has also stopped working for me with no data after 9/11. There is no reason what NEM-PS accounts should be prevented from getting this information as it is just basic readout data from the meter that I believe CPUC mandates providing. In a possibly related event, on...

I often see the same discussion point, but this is too simplistic as it doesn't include the following: Continuing to still pay the utility ~$275/month (OP said $200-$350/month) Utility rate increases Running a basic scenario with your original vs including the payment and 4% vs 5% returns...

The limits are based on a monthly estimated, not daily or hourly. What does your "PAIRED STORAGE: MAXIMUM EXPORT ESTIMATION" table look like? I Unless PG&E has wrong data for your site or you have a near zero house load, you should have a lot of margin. In my cast for July, the PG&E...

I think that you are right to look into this, but you need to look at this holistically with solar, Powerwall, house and grid to understand why this happened. My VPP total discharge was pretty close to the same the 5 hour on Tuesday and the 3 hour on Wednesday, with the rate lower on Tuesday...

The behavior of the Powerwall will be impacted by solar generation, house load in addition to the site export limit. The second graph was for your solar generation. The first graph for Powerwall discharge looks it was discharging as intended during the VPP 6:00-9:00pm period yesterday and...

Looks good, but it isn't operating like it should. A couple of others have reported something similar. Reach out to customer support.
