I will repeat that it is entirely possible for someone to not only not receive credit for any energy pushed back, but be charged for same (billed for it as if they used it). Additionally, if permission to operate has not been granted and a customer chooses to operate their equipment, they must be prepared to accept whatever outcome of that (if any) may arise.
In most cases its none (especially if one has storage and is not pushing much back). In some cases people are double billed, and then have to try to explain why they were operating their equipment before PTO.
Unless a person has a way to absorb what they are generating (operating in a microgrid), I would recommend to anyone who asks NOT to operate their equipment for any real length of time before receiving official PTO. If you have storage its murkier because you can absorb it yourself, so are not really impacting anything.
Here is one such thread here, for example:
Got my first bill for the first full month with my solar + PWs WITHOUT PTO. I sent, unintended, $0.81 to the grid. This was treated as a charge * 2 so instead of my bill being $115.14 - $0.81 it was $115.14 + $0.81 x 2. So energy put back on the grid was not just treated as a charge but charged...
