The difference between kVAh (kilovolt-ampere hours) and kWh (kilowatt-hours) lies in the type of power they measure:
- kWh (kilowatt-hours):
- Definition: kWh is a measure of actual energy consumption. It represents the amount of energy used by a load over some time.
- Calculation: It is calculated by multiplying the power in kilowatts (kW) by the time in hours (h).
- Use: kWh is used to bill consumers for the electricity they use. It measures the real power consumed by electrical devices.
- Formula:
kWh=kW×hours

- kVAh (kilovolt-ampere hours):
- Definition: kVAh is a measure of apparent power consumption. It takes into account both the real power (kW) and the reactive power (kVAR, kilovolt-ampere reactive) in an electrical system.
- Calculation: It is calculated by multiplying the apparent power in kilovolt-amperes (kVA) by the time in hours (h).
- Use: kVAh is used to account for the total power supplied by the utility, which includes both the useful power (kW) and the power lost due to reactance (kVAR). It helps in understanding the efficiency of the power usage.
- Formula:
kVAh=kVA×hours

Key Differences:
- Type of Power: kWh measures real power (useful work done), while kVAh measures apparent power (total power supplied).
- Usage: kWh is used for billing purposes based on actual energy consumed. kVAh is used to measure the total demand on the electrical system, including both real and reactive components.
- Power Factor: kVAh takes into account the power factor (a measure of how effectively the electrical power is being used), whereas kWh does not. The power factor is the ratio of real power to apparent power and is a key component in calculating kVAh.

We, customers are billed in two separate energy units for their usage of electricity: kWh and KVAh. I will explain to you what these two mean.
kWh
The unit of measurement for energy used over time is KWh or kilowatt-hour. The power in kW (Kilowatts) multiplied by the time in hours yields the result. It shows the real quantity of energy used by a client throughout a billing cycle. For instance, a consumer would use 10 kWh of energy if they used a 1 kW item for 10 hours.
KVAh
The unit of measurement for apparent power in an electrical system is KVAh or kilovolt-ampere hour. It is a measurement of the combined usable power (kW) and reactive power (kVAR) that an electrical system uses. The power needed to keep the system's voltage level stable is known as reactive power. Although it doesn't accomplish anything useful, it is necessary for the system to operate correctly.
Difference Between kWh and KVAh
KVAh is a measurement of the overall power used by an electrical system, whereas kWh is a measure of the actual energy utilised by a client. The utility company's goals and the particular conditions will determine which unit is used for billing.
