Very nice explanation of the issue. Just to clarify a point or two, industrial users benefit directly from PF correction of their plants largely because the utility supplier either: a. doesnt' penalize them for low PF, and/or b. credits them for PF above say .90. Payback for PF correction equipment for them is often very fast, maybe just a few months.
The residential or light commercial user's PF is not tracked nor billed, so there is very little to gain money-wise by raising PF. Laryn K8TVZ
