Q2. How calculate plant load factors
Ans. 
Plant load factor is calculated by dividing the actual energy generated by the maximum possible energy that could have been generated.
• Plant load factor = Actual energy generated / Maximum possible energy that could have been generated

• Maximum possible energy is calculated by multiplying the rated capacity of the plant with the number of hours in a given time period

• Plant load factor is expressed as a percentage

• It is used...read more
