Ghatghar Dam refers to two associated gravity dams built using roller-compacted concrete, the first use in India. [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. The upper Ghatghar dam is 15 m (49 ft) tall and on the Pravara River, a tributary of Godavari river. [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. The hydro power project diverts Godavari river basin water outside the basin area to a west flowing river of Western ghats.

Contents

The power station is located between both the upper and lower reservoirs. 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. Construction on the project began in 1995, the dams were placed beginning in 2001 and were complete by 2006. The power station was commissioned in 2008. [5] [6]

Power Plant

The dam's power plant has an installed capacity of 250 MW.

The Pushihe Pumped Storage Power Station is a pumped-storage hydroelectric power station located 54 km (34 mi) northeast of Dandong in Kuandian County of Liaoning Province, China. It was constructed between August 2006 and September 2012. The power station operates by shifting water between an upper and lower reservoir to generate electricity. The lower reservoir was formed with the creation of the Pushihe Lower Dam on the Pushihe River, a tributary of the Yalu River. The Pushihe Upper Reservoir is located in a valley above the east side of the lower reservoir. During periods of low energy demand, such as at night, water is pumped from Pushihe Lower Reservoir up to the upper reservoir. When energy demand is high, the water is released back down to the lower reservoir but the pump turbines that pumped the water up now reverse mode and serve as generators to produce electricity. The process is repeated as necessary and the plant serves as a peaking power plant.
