kilowatt-hour (kWh) is the measure of energy consumption
(power over time).
As an example, a 60 watt light bulb burns power at the
rate of 60 watts (or 0.060kW). In one hour, the bulb will
consume 60 watts times 1 hour, or 60 watt hours). In 12
hours, that same bulb will have consumed 60 watts times 12
hours, or 720 watt hours (0.72kWh). Therefore, a kWh is a
unit of energy.
Kilovolt-Ampere (kVA)
Is a unit of electrical power, often referred to as
Apparent Power. This is what the utility must supply to its
customers on the primary side of the facility transformer
and is the basis for sizing power plants.
Different
facilities may use the same amount of real power (kW), but
different supply levels of apparent power (KVA) depending
on the kind of equipment in the facilities. Equipment with
lots of magnetic fields (like motors) will require more
apparent power to feed the same real power demand. If you
know the kilowatt demand (real power), then you can
calculate the electrical energy consumed over time (kW x
time = energy). There is also a relationship between real
power and apparent power that is based on the concept of
power factor. If you know your real power (kW) and your
power factor, you can calculate your level of apparent
power (KVA).
