Kilowatt (kW)

A unit for measuring electrical energy. One kilowatt is 1,000 watts and equal to 3,413 BTUs. A kilowatt-hour equals one kilowatt of electrical power taken from an electrical circuit steadily for one hour.

Kilowatt Hour (kWh)

Represents the use of 1,000 watts of electricity for one full hour. It is equivalent to 10 100 watt lightbulbs burned simultaneously and continuously for one hour.

kVAR Charges (Reactive Power Charges)

Power factor is a measure of how effectively the current delivered to a motor is converted into useful energy. KVAR reflects the extent that current and voltage cycle in phase. The best and most efficient power factor is 100%, which occurs when current and voltage are perfectly in phase. kVAR is shown as a percentage.
