Due to the large rainfall in the hilly region surrounding the reservoir, some beautiful falls are generated in the monsoon season. The water from Shivasagar reservoir is taken through an intake structure known as Navja tower near village of Navja into the head race tunnel.

But the total generation capacity of the two stages was too large for load forecasts of that time. The earliest known dam is the Jawa Dam in Jordan, kilometres northeast of the capital Amman and this gravity dam featured an originally 9-metre-high and 1 m-wide stone wall, supported by a 50 m-wide earth rampart.

Within two years thereafter, it came to be noticed that the 10 years time tag between these two stages will not be affordable and to cope up with the power requirements, the two stages should be merged and both the stages should be constructed simultaneously.

Tata also covered compensation for employees, police staff.

Generators provide nearly all of the power for electric power grids, the reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities.

Later in the s, the electricity demand of the Maharashtra increased tremendously resulting in inadequate power supply. It has over million inhabitants and its capital, Mumbai, has a population of approximately 18 million, Nagpur is Maharashtras second capital as well as its winter capital. Tachypleus gigas in Odisha.

Initially a two-stage construction was conceived.

The cost of hydroelectricity is relatively low, making it a source of renewable electricity. A dam foot powerhouse was also constructed which is used to generate electricity by the water which is discharged from the Koyna Dam for irrigation purpose.
