Andhra Pradesh Irrigation and Hydropower

Andhra Pradesh Irrigation and Hydropower Projects

Geographically, Andhra Pradesh is in peninsular India consisting of coastal belt on the east and Rayalaseema in the south-west. Therefore, Andhra Pradesh has the advantage of having most of the east flowing rivers in the state bringing in copious supplies from the Western and Eastern Ghats and up to Bay of Bengal. Andhra Pradesh has a heritage of cultivation and irrigation dating back to several centuries. In the past, ancient Kings and rulers built artificial lakes and reservoirs by constructing bunds and anicuts across rivers for creating irrigation potential as well as drinking water for the people. Andhra Pradesh is a riverine state with 40 major, medium and minor rivers. Godavari, Krishna, Vamsadhara, Nagavali and Pennar are major interstate rivers.  It helps to develop Irrigation and Hydropower Projects in Andhra pradesh.

Irrigation Projects:-

  • The total irrigation potential created under major and medium projects before 1956 was 29.73 Lakh Acres, and from 1956 to 02/2015 is 39.35 Lakh Acres.
  • The Irrigation potential created under Minor irrigation and APSIDC since inception up to 02/2015 is 32.63 Lakh Acres.
  • Thus, the total new irrigation potential created under Major, Medium & Minor irrigation and APSIDC in the state is 101.72 Lakh Acres.
  • After independence several important schemes implemented like Nagarjunasagar project, Prakasam Barrage, Sir Arthur Cotton Barrage, Tungabhadra Low-level canal, Kurnool-Cuddapah canal, Kadam project, Romperu drainage project and Upper Pennar project.
  • The projects under the implementation phase are Sriramsagar, Vamsadhara, Srisalim right branch canal, Yeluru Reservoir Scheme, Godavari delta system, etc.
  • Recently Andhra pradesh goverment launch ‘Jalasiri Harati’ scheme to to help keep drought away from the State. Under this Scheme, 28 irrigation projects will be completed.
  • Recently Purushothapatnam project has inaugrated. After 40 long years of wait, the people of East Godavari would get irrigation facility to 2.15 lakh acres spread over Rajanagaram, Peddapuram, Prattipadu, Pithapuram, and Jaggampeta through the Purushothapatnam project.


Hydropower Projects:-

  • The major power projects of the state are-the Nagarjunasagar and Neelam Sanjiva Reddy Sagar (Srisailam Hydel Project), Upper Sileru, Lower Sileru, Tungabhadra Hydel Projects and Nellore, Ramagundam, Kothagudem, Vijayawada and Muddanur thermal projects.
  • Main Hydel power generation projects are Srisailam Hydro Electric Project (installed capacity of 770 MW) and Nagarjunasagar Complex (installed capacity of 960 MW), whereas Vijayawada Thermal Power Station and Kothagudem Thermal Power Station are the main source of thermal power generation with installed capacity of 1260 MW and 1180 MW respectively.
  • Simhadri Thermal Power Station with installed capacity of 1000 MW aims at supplying the entire power generated to the state.
