I was able to get mine processed quickly by filing a complaint with the CPUC.
There is a 150 page 'law' of how the interconnections are to be handled. They have 30 days to process the agreements of the 'small' providers like us (rooftop solar, wind, etc.). Without a complete reading, nor being able to digest it all, my takeaway is:
1. PG&E must contact you within 10 days in WRITING if there is a problem with processing your application.
2. If your application is resubmitted, the 30 day countdown clock starts at the beginning again.
So, my takeaway is that PG&E is working to have us resubmit the applications so that they can avoid crediting us for solar, and they can follow the 'law'.
I would be happy to share my complete story and the names of the people at PG&E that 'worked' on my application.... I hope the CPUC asks me.
Edit: note that the on-line CPUC complaint form does not trigger an email with your case number. They will mail it to you via postal service.
