Ghatghar Dam

[1][2][3] They are situated in Ghatghar village in Ahmednagar district Maharashtra, India.

Both dams create a lower and upper reservoir for the 250 MW pumped-storage hydroelectric power station.

[4] The lower Ghatghar dam is 86 m (282 ft) tall and located on the Shahi Nalla which is a tributary of Ulhas River to the south west of the upper reservoir in a steep valley.

During peak electricity demand hours, water from the upper reservoir turns two 125 MW reversible Francis turbine-generators.

When energy demand is low, such as at night, the turbines reverse direction and pump water from the lower reservoir back to the upper.
