Abstract: “Age of Hydro Electric Plants in India is considered to be about 25 to 30 years. After this age, it is necessary that hydro electric plant should be refurbished, so that we can increase its Generation and efficiency. With the age some parts of the Electric plants are not giving full efficiency due to bear and tear. Generation capacity of the Hydro Electric Plant can be increased by replacement of some of crucial parts and by reducing losses. It is also important to note here that the increasing demand of electric power can be achieved by establishing new Electric Power Plants or by upgrading the old electric Power Plants. Some of the electric plants in India and Hydro Electric Power Plants in Himachal Pradesh particularly are crossing their maximum age limit and it is very important that such Electric Generation Plants should be upgraded. Modernization of electric plants is also a very important aspect to increase the generation capacity of the old power plants. With the passage of time”
