It is defined as the average of all loads that occur on a power station for a given period of time.

Mathematically

Average load (AL) = No of units generated/time Interval (in hours)

List of 100 Basic Electrical Engineering formulas

Based on time interval AL can be categorized into three classes:

Mathematically

**formula can be linked by the following relation:***Average load*Average load (AL) = No of units generated/time Interval (in hours)

List of 100 Basic Electrical Engineering formulas

Based on time interval AL can be categorized into three classes:

- Daily Average load = Units generated in a day / 24 hours
- Monthly average load = Units generated in a month / Number of hours in a month
- Yearly average = Units generated in year / Number of hours in a year

### Example

*Statement: Find the monthly average load of a nuclear power station which generates 5000 MW of power.*
Solution:

MAL = 5000 MW / 720 = (5000 * 1000 kWh) / 720 h = 6944 kW

The AL for the above problem is

__6944 kW__

__Tips:__- Since industrial power is measured in kW, convert MW to kW
- The time interval for both numerator and denominator should be same. In most cases, it counts in an hour
**(h)**

So that was all on the topic. Summarizing above discussions we have three formulas:
