Perunthenaruvi Small Hydro Electric Project

Capacity - 2x3MW=6MW

Perunthenaruvi Small Hydro Electric Project

The proposed Perunthenaruvi Small Hydro Electric Project is a run of the river scheme in river Pamba and is located in Ranny Taluk of Pathanamthitta District. The scheme envisages the utilization of water from 442 sq.km catchment of Pamba and Azhutha rivers for Electricity generation. The installed capacity of the project is 6MW (2X3MW) and is expected to generate 25.77 MU of energy per annum.
