The tail race water from these stages then flows through a channel and joins the Arabian Sea near Chiplun. Meanwhile, the central utility is also in advanced talks with Kerala, Andhra, Tamil Nadu and Uttar Prroject for setting up more solar projects. Then it travels towards the surge tank. Then the water is discharged into the tail race tunnel. NHPC solar project Koyna dam clean energy hydroelectric power plant.

All the generators are located in underground powerhouses excavated deep inside the mountains of the Western Ghats. Originating koya a few kilometers from Arabian Sea, the river has chosen to flow towards Bay of Bengal becoming a lifeline of four states viz.

Later in the s, the electricity demand of the Maharashtra increased tremendously resulting in inadequate power supply. It is further divided into four pressure shafts which run vertically ram delivering water to the turbines.

To use this head, the Kolkewadi Dam was constructed at this location. A nonconventional intake system was created by piercing the lake from the bottom by blasting the rock plug using dynamite.

Today the Koyna Hydroelectric Project is the largest completed hydroelectric power plant in India [2] having a total installed capacity of 1, MW. Koyna dam foot powerhouse: The water in head race tunnel is directly drawn from the reservoir and delivered to the head surge tank. Location of Koyna Dam in Maharashtra. The dam has withstood many earthquakes in the recent past, including the devastating Koynanagar earthquakeresulting in the dam developing some cracks.

Kogna main purpose of the dam is hydroelectricity with some irrigation in neighboring areas. The Koyna Hydroelectric Project is the largest completed hydroelectric power plant in India. After the disaster grouting of the cracks was done.


The 1st and 2nd stages share same powerhouse with total eight Pelton turbine units. This water is drawn from head race tunnels situated below the reservoir. The spillway of the dam is located at the center.

This is also a major attraction for tourists visiting in monsoon prlject. Also lake tapping is proposed for the intake system.
