Capacity - 2.5 MW

Overview

Located at Malampuzha in Palakkad Taluk of Palakkad District. Malampuzha dam constructed across Malapuzha river forms the reservoir for this project. The station utilises the irrigation release for the left bank canal together with spill. The 2.5 MW machine is usually operated during the period November - January. The annual generation potential is 5.6 MU. Turbine is horizontal shaft Kaplan. The machine was commissioned on 26.11.2001. The dam is owned by Irrigation Department. The water released for Irrigation is used for generation. The power generation is at 11 kV and distributed through 1 No 11 kV feeder.
Malampuzha Dam is the second largest Dam and reservoir in Kerala located  Palakkad district .Construction started post-independence by the then Madras State. Situated in the scenic hills if the Western Ghats in the combination of masonry dam with length of 1849 meters and an earthen dam of 220 meters making longest Dam in Kerala. The dam crosses the Malampuzha River, a tributary of Bharathapuzha, Kerala’s  second longest rever. There is a net work of two canal systems that serve the dams reservoir of 42090 Hectares
