I'm trying to use up "excess solar" generated during the day, to avoid those "non-bypassable charges" under NEM2 in California.
So, as I'm trying to optimize this, I have a question:
Does billing occur second-by-second? (i.e. if I send 0.1 kWh to the grid and consume 0.1 kWh from the grid a few seconds later, I'd have to pay NBCs on the 0.1 kWh?)
Or is it hour-by-hour? (i.e. if consume 1 kWh from the grid at 1:00-1:30 pm, I can avoid NBC's by exporting 1 kWh to the grid 1:30-2:00 pm, thereby zeroing out the usage for that hour?)
I realize that the meter is capable of reading the net consumption second-by-second, but I'm wondering whether the billing system uses all that granularity. (When I download my usage data from the PGE website, it only provides usage on an hourly level.)
