Why KWHr on meters instead of KVAHr?
(OP)
Loads can be resistive, inductive or capacitive. However, when we look at the meters it only indicates energy cosumed in KWHr. Are we ignoring the reactive power in billing?

I am guessing a poor powerfactor load equates to high current consumption which equates to higher bills.

eg: If the average power factor for a month was 755 then a penalty of 0.9 - 0.75 or 15% would be applied to the KWHr consumption charges.
Now there are much more punative formulas and some countries charge for any amount of KVARHr consumption, either leading or lagging.
As has been mentioned, KVAR metering and PF penalties were applied to large commercial and industrial users.

It does, of course take money to build lines and equipment to carry kvar and fuel to generate the kWh from losses caused by kvar.
