The typical PUC stipulates that Pocos charge for real power, period.
Then, for the big users, penalties are imposed for poor utilization of Poco assets:
Power Factors below 90
Peak Power surges -- like tanning saloons --
Seasonal Power surges -- like farm pumps --
Time of Day Power peaks -- like massive air conditioning loads
etc.
Power breaks are given for night time users such as an electric steel melter willing to run only on the night shift...
Power breaks are given for users willing to have the Poco cut them off entirely during energy peaks...
etc.
PG&E is rolling out a program to clip air conditioning demand by residential users. It responds to central control by interrupting just the air conditioner power circuits.
Because of all of the possibilities you simply have to have the customers bills in hand.
Now, with net billing on solar, it gets even more complicated. Pretty soon juice will be sold like airline seats.
