the full NEM credit, not just generation charges?I just went through this with my CCA Peninsula Clean Energy a week ago and they told me I would just get $80.00 credit balance rollover but I just got a $135.00 check from them, which actually is the NEM credit balance I have a month after the annual True-Up.
No, it wouldn't make sense. My roof orientation sucks with all of the large areas northwest and northeast. The northwest might be able to take another 2 panels and the northeast could take another 3-4 but it really wouldn't be worth it.Any chance you can slap more solar on your roof now?
That doesn't make sense. Can you share your true-up statement?I just went through this with my CCA Peninsula Clean Energy a week ago and they told me I would just get $80.00 credit balance rollover but I just got a $135.00 check from them, which actually is the NEM credit balance I have a month after the annual True-Up.
This is the email response I got from PCE a month after my True-Up:That doesn't make sense. Can you share your true-up statement?
My NEM balance is generation only with PCE, I pay PG&E for consumption delivery charges only and do not settle NEM with PG&E. You on the other hand have everything in the same PG&E bag.the full NEM credit, not just generation charges?
If so, I stand by my original question.
Interesting, but don't you lose out on the distribution credits? Do I understand this correctly?My NEM balance is generation only with PCE, I pay PG&E for consumption delivery charges only and do not settle NEM with PG&E. You on the other hand have everything in the same PG&E bag.
He is on E-TOU-C. PCE gives credit according to their Generation rates, found here:Interesting, but don't you lose out on the distribution credits? Do I understand this correctly?
Lets say Peak is $.40/kWh of which $.10 is generation. So if you use 10 kWh during peak, you get charged $4. ($3 to PG&E and $1 to PCE). If you export 10 kWh during peak, do you get credit of $4. or $1.?
That's my point. IF I export to PG&E during peak I get credited for the entire amount (Generation plus distribution). So if I export same as I use, I'm zero NEM. If he exports same as he uses, he is losing the distribution fees in his total rates.He is on E-TOU-C. PCE gives credit according to their Generation rates, found here:
That is $0.16966/kWh Summer Peak. So, the PCE credit in your example is about $1.70.
If you are a net generator or your PG&E true-up balance is negative, then it just gets wiped out. You only get what the CCA gives you for your surplus generation. PG&E Net Surplus Compensation does not apply.
PG&E is still doing their own NEM calculations for all the non-Generation portion of the tariff. If you owe money on the Total Rates, it will be basically the same. If you are Zero NEM, it will be the same. If you are a surplus generator, there is a very good chance you will get more money from the CCA than you would from CCA opt-out straight PG&E billing. With straight billing there is the no-man's land between zero dollar energy charges with positive kWh consumption and true net surplus kWh. In that zone, the CCA may still pay you something while PG&E will never pay you anything. Most CCA's also have higher reimbursement than PG&E NSC if you were net surplus kWh at true-up.That's my point.

Which means that you pay the higher of MDCs or NBCs, your NEM charges reset to $0 and that's it.thanks for clarifying that
I'm zero to negative NEM, but still a net consumer
So, your real April true-up was $134.95 which is why they sent you a check? And your next month bill starts over at zero?That doesn't make sense. Can you share your true-up statement?
yes correctWhich means that you pay the higher of MDCs or NBCs, your NEM charges reset to $0 and that's it.
Now that they cash me out I’m certain that $134.95 NEM credit will be gone from my PCE running balance and will start with my May NEM credit. Strange thing is everyone True-Up in April with PCE, and as the email from them told me my True-Up balance of $80.00 or so would be carried over to the new year, instead they pay me the $80.00 + April NEM credit of $54.00 and call it even.So, your real April true-up was $134.95 which is why they sent you a check? And your next month bill starts over at zero?
no SGIP - The Fed credit is a bit more fuzzy on ability to claim and utilize this function it seems.I'm still trying to get my head around export strategy. Your approach sounds easy, and if I'm seeing SDGE EV rate correctly, your super-off-peak $0.10/kWh is enviable. Here in PG&E land we pay $0.25 off peak to charge the car.
First question is what is your situation on the income tax credit for the PW. Grid charging might be a concern for folks who took ITC.
But check me on this regarding maximizing export credits:
My understanding of Non-Bypassible-Charges (NBCs) is that in effect they are a small tax on exported power, roughly 3 cents per kWh, or ~7% reduction in your peak rate credit. Would this mean that re-importing power after the battery is down to the reserve level entails a slight decrease in arbitrage value?
In your case, after PW reaches your reserve during peak, any non-solar power you use before peak ends would be imported. The import price is full retail, including NBCs, but the export is less the NBCs.
Maybe I've got this wrong? Or maybe the $ are insignificant, or I'm just overthinking this.
Might the net credit be a bit higher if you slowed the export so that PW could keep powering the house till the end of peak? Or does solar still have enough to power the house till 9pm?
Since the export rate is not adjustable, maybe one could delay the start of PW export so it ends around 9 when peak ends? However, the export is done at a constant grid power, causing the PW discharge rate to vary with changing solar contribution and house draw, making estimation imprecise.
Thanks,
SW

It behaves differently depending on whether you're using time-based control or self-consumption.I found that there is a setting in the Android app under Settings...Powerwall...Advanced that now allows you to manually turn on and off grid charging. I'm trying it now, but it seems that it will only charge from the grid up to your Backup Reserve setting. This makes sense since you would always want to top off your backup power whenever you can so it's ready for unforseen power outages.
