Karikkayam HEP 15MW (3×5 MW)
Karikkayam Small Hydro Project is located in Chittar Panchayat of Rani Taluk, Pathanamthitta Disrict in the state of Kerala.
Karikkayam HEP is is one of the two small H.E. Projects identified by Kerala State Electricity Board (K.S.E.B.) between Kakkad Power House and Maniyar Barrage on River Kakkad. It is downstream of Ullunkal HEP site. Karikkayam HEP receives controlled discharges from Sabarigiri H.E.Project(360 MW) via Kakkad HEP(50 MW), and eventually via Ullunkal HEP.
Background
The project was allotted to Travancore Electro Chemical Industries Ltd. (TECIL) in 1994 which transferred it to Ayyappa Hydro Power Limited (AHPL) in March, 2006. In September, 2006 EDCL took over AHPL and it became a subsidiary of EDCL.
EDCL through this 100 % subsidiary Special Purpose Vehicle (SPV) company is implementing the Karikkayam project as an Independent Power Producer (IPP).
AHLP has got approval to implement the project by installing 3 units each of 5 MW capacity.
Project Description
The project has a Gross head of 20m and Discharge between 95.23 cumecs and 104.82 cumecs.
It consists of a 26.55 metre high diversion dam across river Kakkad and a dam-toe surface power house with an installed capacity of 15 MW(3X5 MW) located on the left bank of the river. The total length of the concrete gravity weir is 172 m with six gates, each of size 6.5m x 6m.
The power outlet block will be used for taking in water from the Dam to the power house. The power outlet block will accommodate the trash racks, intake gate structures and power intake penstocks based on flow duration data worked out by Kerala State Electricity Board (K.S.E.B.) and based on discharge data compiled from 1981 to 1991 at Maniyar Barrage and Catchment area downstream of Kakkad Power House and Karikkayam HEP site.
