The project installed capacity of Chembukatti Small Hydel Project will be 7 MW with 14.83 MU (Million Units), The Project situates in Palakkad District Mannarkad Taluk and Kottoppadam panchayat. The Proposed site is 25 KM from Mannarkkad – Melatoor route and 5 Km fom Thiruvazhamkunnu. There is no Forest land involved in this project, only private land. A 5m high and 80 meter length weir is to be constructed in Palakkuzhi puzha /velliyar which is a tributary of Kadampuzha which reaches the Arabian sea at Kadalundi. A canal of 1523 meter length has to be constructed from the weir and penstock for a length of 500 meter is to be constructed. The turbine is vertical Francis. Detailed Investigation Report has been prepared by K.S.E.B. Limited.
