Not true you clueless troll. Have you ever even read a tariff? A nice
industry not far from me has several rolling mills for working aluminum.
Each 'roller' that carries material into / out of the mill is driven by a
separate motor. All three-phase, none are pf-corrected. Often the motor
is
unloaded and just spinning the roller waiting for material to come on to
it.
So when idle their pf is not particularly good. Yet they are not subject
to
special low-pf tariffs. They get billed for the kwh they use only.
Ever try and pf-correct a three-phase motor that is unloaded about
two-thirds the time and full-loaded the other third of the time? Now do
it
with sixty identical motors. Get back to me with a cost/benefit of adding
such pf-correction.

Well then they wouldn't be a 'commercial' customer now would they? Or
maybe
you're too clueless to know the difference?

You obviously have never worked in the field or worked with industrial
equipment. You don't get charged 'a different rate' unless your pf is way
down below 0.6 or less when operating near rating. Most industry and
commercial customers don't have that problem. The rolling mill I
mentioned
earlier has a pretty low pf when idling between ingots of aluminum to be
rolled, but that's with little 'real load'. So although they have a low
pf
several times a day, when they are drawing near rated (i.e. when
cold-rolling), their pf is quite good. Not unity, but above 0.9.

You probably can't even calculate what the losses are or how much it costs
to correct a pf. Why don't you take your 10-year-old potty mouth and ask
someone that works in the field how they decide when to add pf-correction?
