Nagarjuna Sagar tail pond

Nagarjuna Sagar tail pond
Nagarjuna Sagar tail pond is a multipurpose reservoir located 21 km downstream of Nagarjuna Sagar dam across the Krishna river near Satrasala in Guntur district. Its gross storage capacity of water is 6 Tmcft. [1] The area of diffusion of water from the reservoir extends to the foot of Nagarjuna Sagar Dam. The project is under construction and is expected to be completed in July 2014. [2]

Hydro electricity generation
Two units of 25 MW each hydro power generation units are under construction by APGENCO to use available through the dam the flood waters of the river and the water released to the requirements Prakasam Barrage load.

Peaking power generation
Currently, the 700 MW reversible hydroelectric turbines (7 x 100 MW), located at the tip of Nagarjuna Sagar dam can not operate in pumping mode due to the unavailability of the pond queue to store the water released during the generation mode energy. With the completion of the pond tail, surplus electricity from the grid is used to pump water back into the reservoir Nagarjuna Sagar and recycling to meet the peak load on daily basis. Therefore surplus electricity consumed when available and used to meet peak electricity requirements without letting the tail pond water Nagarjuna Sagar. 700 MW peaking power for eight hours can be fulfilled which Tmcft live storage capacity of available water in the pond tail.

The irrigation potential
200 Tmcft surplus water per year from the Godavari River is scheduled to be introduced in this pond tail Dummugudem Levante Irrigation Scheme is running. The pond water transferred to this queue to be pumped up current gross capacity water storage tank 410 Nagarjuna Sagar Tmcft to feed his right and the left bank channels. So Nagarjuna Sagar reservoir does not have to be supplied with water from the Srisailam dam upstream. [3] As the tail water level (48.33 m MSL) of this dam is below the full reservoir level (53.34 m MSL) Pulichintala downstream the dam, surplus water in the tank Pulichinthala can be pumped by providing units pumped storage Pulichinthala tank of Nagarjunasagar through this pond water retained in the reservoir Srisailam be used for upstream water use from JuraAbout and Srisailam reservoirs for irrigation needs in highland regions Telangana and Rayalaseema. The water reservoir Nagarjuna Sagar also be pumped to Srisailam Srisailam reservoir by central bank left hydropower (900 MW) in the pumping mode in case of severe drought in the Krishna river basin. Koilsagar lift irrigation project (about 16 ° 23'49 "N 77 ° 39'30" E), lift irrigation project Rajiv Bhima, lift irrigation project Nettampadu (about 16 ° 18'58 "N 77 ° 40 '21 "E), lift irrigation system Kalwakurthy, Srisailam Left Bank Canal, Telugu Ganga project irrigation, lift irrigation project Handri Neeva, irrigation project Galeru Nagari, Veligonda irrigation project etc., which are in advanced stage of construction, depend Krishna river water available in JuraAbout / Srisailam dam.

A canal lift from the Krishna River (16 ° 42'50 "N 80 ° 08'24" E 20 m MSL) downstream of the dam will be executed Pulichintala for feeding water diverted from Polavaram Godavari some of the existing control zone (located 60 m below MSL) in Nagarjuna Sagar right bank of the canal to facilitate the extension of Nagarjuna Sagar right bank canal connects the feed channel Kandaleru / deposit Somasila
