The correct answer is: A. Peak load plant
A peak load plant is a type of power plant that is used to meet the peak demand for electricity. This demand typically occurs during the day, when people are at work and using electricity for things like air conditioning and appliances. Peak load plants are often gas-fired or oil-fired, and they can be started and stopped quickly to meet the changing demand for electricity.
However, peak load plants are not very efficient, and they can be expensive to operate. As a result, they are not used to meet the base load, which is the minimum amount of electricity that is always needed. The base load is typically met by nuclear power plants, hydroelectric plants, and coal-fired power plants. These plants are all very efficient, and they can operate 24 hours a day, 7 days a week.
Therefore, the answer to the question “Which plant can never have 100 percent load factor?” is A. Peak load plant.
