Hydropower Generation Performance in Sutlej River Basin

The Sutlej River Basin is the major part of Indus River Basin. It is the easternmost tributary of the Indus River. It rises near the Darma Pass near Mansarovar Lake, enters the Zarkar range and flows through Tibet before entering India. It cuts through the Great Himalayan range and the outer Himalayas and enters the plains at Roper. It receives the Beas River at Harike at Punjab and forms the boundary between India and Pakistan for nearly 120 km. It finally enters Pakistan near Sulemanki.

The project wise generation data of large hydro (above 25 MW) with installed capacity of the basin in the latest year 2012-13 is follows.

The above graph shows the trend line of power generation of large Hydropower projects for last 28 years in the Sutlej basin. The trend-line shows diminishing generation from existing hydro power projects of Sutlej River Basin.
It shows that the per MW generation in 2012-13 (4.19) has dropped by a huge 31.09% from the highest per MW generation (6.08) achieved in the year 1998-99.
All generation figures have been taken from official data of Central Electricity Authority (CEA).
