comparison between various type of power station :-
Hydro-power plant:- 1.Capital cost is very high on account of heavy cost of erection of dam and machinery.
2.No fuel is used its running cost is very low.
3.They can be started instantly
4.They require a large space for reservoir and construction of dam.
5.Very less maintenance is required.
6.They depend upon the rain fall and a long dry season may affect the power generation.
7. These plants are located at places where dams can be errected and huges quantity of water is collected at a sufficient head.
8. These power plant are located far away from load center therefore long transmission lines are required and hence cost of transmission and distribution is very high.
9. As no fuel is used,therefore cost of trans-potation of fuel is nil.
10.These plant are most simple and clean.
Steam power-plant:- 1. Capital cost is low in comparison to that of hydro and nuclear power stations.
2. Running cost is low as compared to disesel power power station due to low cost of fuel.but more than hydro and nuclear power stations.
3. They require long time for starting.
4. They require smaller space in comparison to that of hydro and nuclear power station but more than diesel power stations.
5. They need more maintenance as compared to diesel and hydro power plant.
6. coal- fuel is limited and coal mines may get exhaust.
7.These plants are located near the load center having the facilities such as supply of fuel ,water transportation facilities.
8. These plants are located near the load center.
9. Cost of transportation of fuel is very high.
10. These plants are not so simple and atmosphere is polluted by fumes and residues of pulverized fuel.
Diesel power plant:- 1. Capital cost is minimum.
2. Running cost is very high.
3. They can be started quickely.
4. They require very less space.
5.They need more maintenance as compared to other.
6.Diesel oil- fuel is not available in plenty.
7.These plants can be installed at any place,
8.Transmission and distribution cost almost nil.
9. These plants are simple and clean compared to steam power plants.
10. These plants are also less reliable due to non-availbility of fuel.
Nucleare power stations:- 1.Capital cost is very high.
2. Running cost is very low as compared to diesel power stations.
3. They require long time for starting.
4. They require smaller space than hydro electric power station.
5.They need much more maintenance than other power plants.
6.These plants are located near to load center.
7. Cost of transportation of fuel is very low.
8. These plant is very complicated to operate and special care is taken to remove the radioactive.
