Electrical Engineering XYZ MCQs
Which of following generating plants has the minimum operating cost:
- Steam plants
- Diesel plants
- Nuclear plants
- Hydroelectric plant
Correct answer: 4. Hydroelectric plant
Explanation:
- Hydroelectric Plants:
- Hydroelectric plants generate electricity by harnessing the energy of flowing water to turn turbines.
- Operating costs for hydroelectric plants are generally the lowest among all types of generating plants.
- Once the infrastructure is in place, the ongoing costs primarily involve maintenance and occasional upgrades.
- There are minimal fuel costs since water, the fuel source, is freely available, and there are no emissions associated with electricity generation.
