Abstract
There is a fast depletion of renewable sources that was used in the past for the generation of electricity and the difficulty in reachability of the grid supply to the remote villages was a big challenge faced. The best possible remedial measure in this scenario is to make use of the natural resources available to generate electricity. In an endeavourance towards this end, the paper has been formulated for the electrification of valara village in Idukki district of Kerala, India. Valara is a kind of locality in which there is a tribal settlement of about 120 families that do not have privilege of electrical energy supply. The present work focus on the preliminary studies carried out at the site for the development of a complete micro hydro power plant which focuses on three main folds such as technical as well as economical feasibility studies, design of civil works and selection of electro mechanical components. The results of the study reveal that there is a huge potential at the site to develop a micro hydro power plant which would meet the energy demand of the tribal settlement and thereby improving their living condition.
Site Investigation
The project site Valara is located in the Adimali Grama Panchayat of Idukki district in Kerala. The site is located at a distance of 14 Km from Adimali. The site is connected by road from Kothamangalam to Adimali. The site is very near to the main road. The stream is a seasonal one, but it has more discharge in rainy season because of its large catchment. The catchment of Valara waterfall is located between 10°18′36″N latitude and 76°29′45″E longitude. About 70% of the catchment area is under dense mixed forest and rest of the area is utilized for human settlements and cultivation of rubber, cardamom, tapioca, areca nut and coconut. The catchment of Valara was identified using the top sheet and it is about 63 Km2 . The head of the water fall is 80 m and it is situated at an elevation of 460 m from mean sea level. During the survey, the possible location for weir, forebay tank, penstock, turbine, power house were also identified.
