Capacity - (3x3.5 MW)
The Malankara Small Hydro Electric Project is a dam toe power house, utilizes the excess water available in the Malankara Dam Reservoir after the irrigation needs with an assured discharge of 25 M3/sec.to the Todupuzha river. Main inflow of the Malankra dam reservoir is the tail race water from Idukki HEP and hence water is available for generation round the year. Malankara Dam is the property of Kerala State Irrigation Department (MVIP). The generated power is evacuated through Malankara -Moolamattam & Malankara – Thodupuzha 66kV Feeders.
The project with installed capacity 10.5MW (3 (2+1) x 3.5 MW) dedicated to the nation on 23rd October 2005. M/s Silk Ltd.,Thrissur carried out the design,supply,erection testing and commissiong of generating equipmemts in collaboration with M/s Koessler Austria and that of 66kV Substation by M/s Telk Ltd., Angamaly. Civil works carried out by M/s West Coast Concrete Products, Angamaly.
