The need for harnessing hydro power, big or small, which is a renewable source of energy, is increasing throughout the world to meet the growing demand for energy. Small, Mini and Micro hydropower are well-recognized renewable sources which can provide electricity especially for the remote rural areas and hilly terrains of our country in a cost effective and environmentally benign manner. Kerala has a vast untapped hydro potential. The state is endowed with a large number of mountain streams originating from the higher elevations of the Western Ghats. These resources offer abundant scope for the development of small hydro power projects.

A penstock commencing from the surge tank is proposed to feed the two machines of each 2.25MW capacity. A surface powerhouse, with horizontal Francis Turbine is proposed at the right bank of the river with an installed capacity of 4.5MW (2x2.25 MW) anticipating 10 % over load.

The civil works of the projects was commenced in December 2015. The tender for the Hydro-Mechanical and Electro-Mechanical works are already awarded and currently progresses through the design and manufacturing stages.
