Andrew -
The kilowatt hour energy consumption is the true amount of electric
energy you are using regardless of your power factor. If you have a power
factor below 100% the reactive wattage is a circulating wattage that you do
not use. It does create losses and this is covered by a fixed amount per KHW
that you pay regardless of your power factor between 80% and 100%. With
this method of metering and billing the electric company saves the cost of
using more expensive metering for each of its customers.
If you are a big user of electricity and the pf is below 80% the electric
company will add extra metering to charge you for the low pf.
