Load factor is the ratio of average load and maximum load and plant factor is the ratio of average load and plant capacity. Here average load will be 7.5KW and plant capacity will be 18.75KW so reserve will be 3.75KW

A power plant has a maximum demand of 15 MW. The load factor is 50% an...
Given data:
Maximum demand = 15 MW
Load factor = 50%
Plant factor = 40%
Calculation:
1. Base Load:
Base load is the minimum level of power demand that occurs continuously in a power system.
Base Load = Maximum demand x Load factor
= 15 MW x 0.5
= 7.5 MW
2. Plant Capacity:
Plant capacity is the maximum power that can be generated by the power plant.
Plant Capacity = Maximum demand / Plant factor
= 15 MW / 0.4
= 37.5 MW
3. Operating Reserve:
Operating reserve is the amount of power that is available to meet the sudden increase in demand or in case of any emergency.
Operating Reserve = Plant Capacity - Maximum demand
= 37.5 MW - 15 MW
= 22.5 MW
But, the question asks for operating reserve based on the base load.
Operating Reserve = Plant Capacity - Base load
= 37.5 MW - 7.5 MW
= 30 MW x 0.25
= 7.5 MW
Therefore, the operating reserve is 7.5 MW.
Hence, option B is the correct answer.
Maximum demand = 15 MW
Load factor = 50%
Plant factor = 40%
Calculation:
1. Base Load:
Base load is the minimum level of power demand that occurs continuously in a power system.
Base Load = Maximum demand x Load factor
= 15 MW x 0.5
= 7.5 MW
2. Plant Capacity:
Plant capacity is the maximum power that can be generated by the power plant.
Plant Capacity = Maximum demand / Plant factor
= 15 MW / 0.4
= 37.5 MW
3. Operating Reserve:
Operating reserve is the amount of power that is available to meet the sudden increase in demand or in case of any emergency.
Operating Reserve = Plant Capacity - Maximum demand
= 37.5 MW - 15 MW
= 22.5 MW
But, the question asks for operating reserve based on the base load.
Operating Reserve = Plant Capacity - Base load
= 37.5 MW - 7.5 MW
= 30 MW x 0.25
= 7.5 MW
Therefore, the operating reserve is 7.5 MW.
Hence, option B is the correct answer.
