Electrical Engineering XYZ MCQs
The advantage of hydro electric power station over thermal power station is:
- Its operation cost is low
- It can supply the power throughout the year
- Its initial cost is low
- It can be constructed anywhere the energy is required
Correct answer: 1. Its operation cost is low
Explanation: Hydroelectric power stations often have lower operating costs compared to thermal power stations. Once built, the ongoing operational expenses of a hydroelectric plant are generally lower because they do not require fuel costs, and maintenance costs can be lower due to simpler machinery.
