Veluthodu dam (Malayalam: വെളുത്തോട് അണക്കെട്ട് ) is a part of Kakkad Hydro Electric Project and is located in Seethathode panchayath of Ranni Taluk in Pathanamthitta District of Kerala, India.[1] Its a Concrete-Gravity dam built across the Veluthodu river, a tributary of Kakkad River which is again a tributary of Pamba River[2][3] The dam is built primarily for electricity. This diversion dam diverts water to the water conductor system from Moozhiyar reservoir to Kakkad Power Station. This power station utilises the tail race water from Sabarigiri power station and flow received from moozhiyar and velluthode rivers.[4] After power generation, water from Kakkad power station is released to the Kakkad River. Taluks through which release flow are Ranni, Konni, Kozhencherry, Thiruvalla, Chengannur, Kuttanadu, Mavelikara and Karthikappally[5] It is operated by Kerala State Electricity Board.[6]

Kakkad Hydro Electric Project

The Kakkad Hydroelectric Project generates 50 MW of electricity using 2 turbines of 25 MW each year. The annual output is 262 MU. The machine was commissioned on 16 September 1999. The Moozhiyar Dam creates the main reservoir of this project.[11] the second reservoir is formed by the Veluthodu dam. After power generation, water from Kakkad power station is released to the Kakkad River.[12][13] The prime mover is a vertical shaft francis Turbine.

The Kakkad project had a long tale of unending woes of corruption and trade union militancy[14]
