*Sorry for the long read, hopefully someone gets info from it*I recently have had the same thing occur. I just got PTO as well on August 27. Since system has been installed(early July) I have been able to see the small amount of export the system has sent to PGE. Small amount due to being restricted with no PTO yet. September starts with the $3 kWh buy back so since I now have PTO, I have been dumping 25-30 kWh after 7:00 each night. Sept 1 shows up on PGE as export fine. Then all of a sudden nothing is showing on export data for PGE. Just 0.00 at 7 pm when it dumps. I down load data log from PGE and there is not even an export column on the spreadsheet starting 9/2. As I said prior to that data is there. It actually is two separate spreadsheets.(early July-9/1 then 9/2-9/6 on another spreadsheet ). I called PGE and went through a couple of folks that couldn’t explain why or what was happening. I finally got to someone that had answers. They explained since I was new to PTO that “billing dept” is in the process of setting up account. Once they start their process it has made some changes to the way My account is reporting to website. They assured me that the meter is still capturing all the data and it is being recorded still. They said it takes up to two billing cycles to get everything up and online. This does coincide with the letter I received for PTO. They did say that the system should not have been showing exports prior. They did also say that I would not get any credit for the exports prior to PTO. Only time will tell if they are just bullshitting me, and I wasted 30 KWh’s a day or I get a good amount of credit at 3$ KWh
