    1. Idukki :

The construction of this Dam commenced on 30 April 1969. Storage of water in idukki reservoir commenced in February,1973. The inauguration of trial run of the first machine was celebrated on 4th October,1975. Commercial operation of the Power Station was Commissioned on 12 February 1976 by the then Hon.

2.     Idamalaya

Idamalayar Dam is a multipurpose concrete gravity dam located at Ennakal, Ernakulam.  Near Bhoothathankettu, on the Idamalayar River, a tributary of the Periyar River in Kerala, South India. Completed in 1985, with a length of 373 metres (1,224 ft), the dam created a multipurpose reservoir covering 28.3 km² (10.9 sq mi) in the scenic hills of the Western Ghats.

3.    Sabarigiri :

Sabarigiri Hydro Electric Project (IHEP) is the second largest hydro electric project in Kerala. The project was commissioned in 1966 with an installed capacity of 300 MW. The RMU of the Project was undertaken during the period from 2005 to 2009, increasing the installed capacity to 340 MW.

 

The reservoir storage is utilized by a hydroelectric power station which has an installed capacity of 75 MW with two units of 37.5 MW capacity, producing an annual energy output of 380 GW·h.

The large reservoir created by the Idamalayar Dam is operated by the Kerala State Electricity Board to augment its peak power generation requirements. The dam will benefit the Idamalayar Irrigation Development Project by diverting water released from the tail race channel of the Idamalayar power station.

 

4.     Pallivasal :
