How does unbalanced loading systems(3 phase) affect prepaid metering (billing/charging)? When loads are not balanced, is it going to affect units consumed in any way versus a balanced loading system?

No, if the metering is done correctly it will be indifferent to the degree of imbalance. The utility might object if it is really severely unbalanced.

Alan, can you come again as i did not quite get you.
To clarify further - My point is, on a three phase metering system using prepaid meters, what would be the difference in energy units consumed if say the currents drawn across phases are 7A, 12A & 20A against a balanced system with currents drawn being 13A, 13A, 13A (across phases).?
Under these loading conditions, are the energy units consumed going to be the same or different at the end of the day/week/month???

The consumption will not be affected, however the neutral conductor.will be affected by high unbalanced currents.
