Electrical Engineering XYZ MCQ
Which of the following is not base load power plant:
- Nuclear
- Pump storage
- Diesel
- Run water
Correct answer: 2. Pump storage
Explanation: Pump storage is not a base load power plant. It is a type of hydroelectric power plant that can act as a form of energy storage. During periods of low electricity demand, excess energy from the grid is used to pump water from a lower reservoir to an upper reservoir. When electricity demand is high, the stored water is released from the upper reservoir to the lower reservoir, passing through turbines to generate electricity. While it can provide valuable grid stability and respond quickly to changes in demand, it does not operate continuously like a base load power plant.
