SABARIGIRI HYDRO ELECTRIC POWER PLANT
CAPACITY – 4 × 55 MW + 2 × 60 MW = 340 MW
The Sabarigiri Hydro Electric Project is the second largest Hydro Electric Project of Kerala State. It is located in Pathanamthitta district of Kerala.This Indo-American project was commissioned on 28th August 1967 by His Excellency then President of India Sri.V.V.Giri. There are two main reservoirs under Sabarigiri HEP scheme namely Kakki and Pamba reservoir. Both these reservoirs are interconnected through underground tunnel. The Kakki reservoir consists of two dams namely, Kakki dam and Anathode dam. The Kakki dam is a concrete gravity dam on Kakki river. Anathode dam is a small dam located on a river which is a tributary of Kakki river. Small augmentation reservoirs viz Kullar-Gavi, Meenar I & Meenar II are serially connected to Pamba reservoir and also Upper Moozhiyar augmenting flow to Kakki reservoir.The power house of Sabarigiri HEP receives water from Kakki dam through a tunnel and discharges into Moozhiyar dam with an installed capacity of 340 MW.The power house consists of four generators of 55 MW and two generators of 60 MW.
The tail race water released from Sabarigiri power house is further utilised to generate hydropower at 5 different power Houses in the downstream side as given below:
1. Kakkad Power house
2. Ullumkal Power house
3. Karikkayam Power house
4. Carborandom HEP
5. Ranni-Perinad Power house.
