PGE NEM Bill seems wrong

[Timr]

I have a paid in full 7.4 KW system with a 10 KW battery that was already installed when I bought my house. It was sized to be 105% of the consumption of the previous owner. It is my second house with solar. My first house I went through the joy of selecting an installer to get it installed with no hitch. I am living in Lemoore, CA and my bills for the last three months are unusually high with 0 KW being sent back to the grid. I have called PGE and have been getting all sorts of excuses after being on hold for 30 minutes each call. I finally found an old bill of the previous owner and discovered that there is a wierd EST PVGEN item on my bill where the channel id is which is not subtracting C from A. Does anyone else have that issue? Is that common for PGE or is there a legitimate billing mistake? My concern is that I will be billed incorrectly all year and then reimbursed at 3 cents a KW for what I produced at the yearly trueup. Is my concern legitimate or is this normal for PGE solar customers? If not normal I will physically go into an office and get it corrected.

Thanks!

That doesn't look like my PG & E bill. I have not heard of ETOUAWB tarriff. How did you decide to chose that rate? What rate options did you see when you signed up? When is your True Up date? If you have a battery, how is the inverter programmed for load shifting? Do you have data from the Inverter about production, consumption and sell to grid? In a conversation with PG & E, I would start with comparing how the PG & E number compares to your inverter "sell to grid" number and consumption number?

Also, are you part of a SGIP program? Can you get a copy of the NEM agreement. It appears there are Non Bypassable Charges so I assume you are on NEM 2.0.

Are you sure you only have one meter? That looks like a bill for the standard non generation meter in a multi-meter setup. Maybe when the guy moved he had your generation meter added to his account

Ampster my rate plan is E-TOU-A. I chose it as I was told I had to use a time of use plan and it seemed to be better than E-TOU-B. Since I have a battery I might change the rate plan to Home Charging EV2-A if PG&E does not fix my bill. Those are my three options of rates. My true up date is September 2020. I do not know how the inverter is setup for load shifting. From what the previous owner told me is that the battery will send everything at 5am to the grid. However looking at the Sunrun website the battery does not do anything until the summer. I use the Sun Run app for production. I asked Sunrun if there was any way to view production, consumption and sell to grid. They only can provide production. PG& E will not provide production, consumption and what I am sending to grid on their website they said due to the battery. I do not know what a SGIP program is. I am on NEM 2.0.

Pir8radio thank you for the manual I will print it and take it in to PG&E on Friday when I am off.

SGIP (Self Generation Incentive Program) is a grant program that the original owner may have used to get a rebate. It may limit how the battery can be used. PG & E should be able to tell you since they administered the funds.

You may want to find out more about the capabilities of your inverter/battery system. I would be surprised if it can not measure output and consumption and sell to grid. There are 3rd party devices that can do that if you want the data. Who is the manufacturer of the inverter?
Do you have multiple meters?

Speaking of data, what is it about your bill that PG & E needs to fix? How many kWhrs were you charged for and how many kWhrs did you get credit for generating last month? If you have an EV and charge at home I would definitely change to the EV rate since it offers the lowest cost off peak rate. The only reason not to do that is if your consumption is high during the peak times. The PG & E website can give you that data unless you have multiple meters on NEM Agregation billing.

That sheet you posted looks like one I used to get with SCE on a NEM agregation billing arrangement. If that is the case I doubt anyone at a PG & E office would be able to help you. In the case of SCE, there was one person that put that spreadsheet together and she was only reachable by phone. Not many customer service people understand NEM Agregation.
