Question

Power Plant having lowest running and maintenance cost is:-
1. diesel
2. hydel
3. thermal
4. nuclear

Answer 1

Correct Answer - Option 2 : hydel

• The Hydro-electric power plant has a high initial cost, least running & maintenance cost among all types of power generation plants.
• The initial cost of the hydro-electric power plant is very high due to dam structure, and other essentials.
•  Because Hydro-electric power plant has fewer moving equipment, a rigid structure then the operating and maintenance cost reduces.
• Another factor in operations is the fuel cost which is practically free for hydro stations.
• Where a typical coal-fired plant is has a coal handling unit, a DM water unit, a generating unit, a cooling water unit, and an ash handling unit while a hydro plant has a generating unit only.
