A measure of the average load, in kilowatts, supplied during a given period. It is used to determine the total amount of energy that would have been used if a given customer's maximum load was sustained over an extended period of time. This value offers a useful comparison to show what percentage of a customer's potential usage is actually used.

Load factor is fairly complex calculation which is derived this way:

(kWH of energy used x 100) / (maximum kilowatt demand x hours in the measured period)
