Just purchased a Kill-a-watt meter. It has a PF setting. What do the energy providers do to combat low PF?
The unit is capable of measuring the power factor of the load under test.
I run my PC thru a UPS and the measured PF of this setup is 0.50
Thus this mean that the power utility is only charging me for half of the actual energy usage?
I am being told that the electric meter will only register loads that are in-phase.

Very few USA residential customers' bills include any charge for power factor, regardless of how low (less than 1.00) their power factor is. this is usually a charge to commercial or industrial classes of consumers. While some household appliances such as an aircon, 'fridge, washing machine, flourescent lights, (and, yeah, a ups) have "poor" power factors, the average for the whole service is generally about 0.8 or 0.75. However, to supply a power factor less than 1.00 requires a greater current by approx. 1/PF. This additional current causes increased wattage (which you are charged for) losses in the wiring, and the increase is by the square of the increases current level. So, you do pay extra for a low power factor. Utilities will add capacitor banks in their systems to improve the system power factor. Customers-not the utility-will add cap banks at their service entrance or at the "offending" appliance (usually a motor) to "correct" their power factor to 1.00 or near 1.00 to avoid power factor charges.
