Load factor

Load factor is a measure of the efficiency with which electrical energy is used.

It is defined as the ratio of the average load over a given period to the maximum load during that same period.

Significance:

  • A higher load factor indicates a more consistent and efficient use of electrical energy, which can lead to reduced operational costs.
  • A lower load factor suggests that there is a significant difference between the average load and the peak load, meaning energy usage is inconsistent, which can lead to inefficiencies and higher costs.

Additional Information Demand factor: It is defined as the ratio of maximum demand on the power station to its connected load.


 Utilization factor: It is the ratio of maximum demand on the power station to the rated capacity of the power station.

Diversity factor: The sum of individual maximum demands to the maximum demand on the power station is known as a diversity factor.

Plant capacity factor: It is the ratio of actual energy produced to the maximum possible energy that could have been made during a given period.
