Cauvery Small Hydro Project (Right Bank)


    The development of Power Sector until recently in India has been primarily with the State and Central Governments with very little participation by Private Sector.  The country faces an energy shortage of around 10.8% and peak load capacity shortage to the extent of about 14.40%.  The situation in Karnataka State is no better and is hindering its economic growth.  In order to mobilize more funds for development of the Power Sector, Government of India has framed a policy to permit private sector participation in the development of the power sector. Under this policy, the Government of Karnataka has allotted implementation of Cauvery Small Hydro Project (Right Bank) to Vijaya Green Power Pvt. Ltd., Bangalore.

    Cauvery Small Hydro Project (Right Bank) is proposed across River Cauvery near Nettakalu Village of Malalvalli Taluk in Mandya District, Karnataka.


    The scheme comprises of the construction of:

  • Diversion weir (ungated)
  • HRT Intake
  • Head Race Tunnel
  • Surge Shaft
  • Penstock tunnel with steel liner
  • Single line of M.S. Buried Penstock, bifurcating into two penstocks connecting to two units
  • Surface Power House to accommodate 2 generating units of 12 MW each and with service bay, control room, office etc.
  • Tail race Pool
  • An Out Door Yard (ODY) of size 54.5 m x 22m.
  • Transmission line.


    The total project cost of the completed scheme, inclusive of Transmission Lines and related escalation, financial costs according to the price level of the year 2008-09 is Rs.9508 Lakhs. The project can be implemented in 27 months.

    The average annual power generation is arrived at 43.41 GWHr. The project gives an internal rate of return of 8.97%.

    In the context of current power and energy shortage in the State of Karnataka and the ever-increasing demand for more electricity, the implementation of Cauvery Small Hydro Project (Right Bank) contributes to partially meeting the shortage of power and energy in the State of Karnataka. The significant aspects of the Project are:

  • There is an assured available head of about 76.84m and flow of about 36cumecs.
  • The Project is not attractive considering the sale rate of energy as Rs. 2.8 per kWHr. It provides an IRR of 8.97% and DSCR at 1.28.
