It's the same in California. The problem is that the delivery charges are also calculated per kWh (so, the cost of delivering a single unit of electricity to your house). But what happens when the net electricity delivered is zero?

You could argue that customers should be charged for both the electricity delivered to their house and the electricity taken away from their house, since they are using the grid and other expensive infrastructure for both. However you are now disincentivising people from installing solar and giving back their excess power.

Thanks, this is the detail I was missing. Net billing for delivery makes zero sense. I think the reasonable solution is to bill the consumption direction only.
