1 KALLADA HYDRO ELECTRIC PROJECT
The Kallada power station utilises the water release from Kallada Irrigation Reservoir. Kallada power station is the first of its kind in Kerala in utilising the water for irrigation release for power generation. The dam is owned by the Irrigation Department . After power generation, water from the power station is released to the Kallada River. From there it is diverted to irrigation canal by diversion weir during irrigation seasons The Power generated in the station is evacuated through two 66 kV feeders.
