The Srisailam Dam is a dam constructed across the Krishna River at Srisailam in the Kurnool district in the state of Andhra Pradesh in India and is the 2nd largest capacity hydroelectric project in the country. The dam was constructed in a deep gorge in the Nallamala Hills, 300 m (980 ft) above sea level. It is 512 m (1,680 ft) long, 145 m (476 ft) high and has 12 radial crest gates. It has a reservoir of 800 km2 (310 sq mt). The left bank power station houses 6×150 MW reversible Francis-pump turbines (for pumped-storage) and the right bank contains 7×110 MW Francis-turbine generators.
Power generation optimization:
At present the initial inflows in to Srisailam reservoir are stored excessively without using for power generation. The flood water fills the remaining empty Srisailam reservoir quickly and most of the flood water overflows in to downstream Nagarjunasagar reservoir without being used for power generation. The endeavor shall be to fill the Nagarjunasagar reservoir fully with the uniform water released through the power generating units.
