What are some disadvantages of hydroelectric power plant?

1 Answer

The disadvantages of the hydroelectric power plant are as follows :

  • The hydroelectric power plant can be developed only where the large quantity of water is available. 
  • The hydroelectric power plant cannot be used where there is lack of water supply.
  • Dams may fail which may cause flooding.
  • The capital cost of the generator is high.
  • The distance between the Hydroelectric power plant and load center is more so the longer transmission line is required which increases costs.
  • Initial civil engineering costs may be high.

These are some disadvantages of the hydroelectric power plant.
