How to convert Kilowatts (kW) to Kilowatt-hours (kWh)

The formula to convert load power requirements in kilowatts (kW) to the energy used in an hour (kw) is:

Load power (kw) x time run for (hours) = answer (kWh)

If you have a generator rated at 100kW with a day-tank of fuel for 8hours, the total load in kWh is:

100 (kw) x 8 (hours) = 800kWh

If the load on the generator is only 50kW then the same coniguration would provide a total kilowatt-hours of:

(100 / 50 ) = 2 × 800kWh = 1600kWh
