John, I know power engineering was your speciality, and I've never worked in the field. But I'm fairly sure kwh meters measure actual power, not volt-amps. The traditional mechanical meters have both voltage and current windings; if current and voltage are out of phase, that will be reflected in the number of watt-hours recorded by the meter. I think the newer "smart" meters can record not just kwh, but average current, voltage, power factor and a bunch of other stuff.

Of course, utilities can and do penalize customers with low power factors. Look at it this way: if the power company could charge based on volt-amps rather than watts, they wouldn't be too concerned about customers with poor power factors.

Hey there Mark, Actually AC Power Distribution was more my specialty and while I worked a lot with Power Factor and Power Factor Correction, Im very rusty in that area as well as the types of modern or "smart" KWH Meters etc. Like I used to tell my kids "Old dad knows some things but NOT everything" HOWEVER the things I DID SAY about what PF is and its definition etc is I believe accurate.........I may have to break down and refresh myself in this area but Im too lazy and old for that. The "stuff" I do know I'm glad to share and help people with as you well know.
