Abstract of the Project


The Ministry of Science & Technology, Govt. of India has accorded approval to the development of the Dailong Micro Hydel Project (2 x50) kw, which is being implemented as a demonstration projrct by the Manipur Science & Technology Council (MASTEC) with the technical assistance of the DST, GoI, the Indian Institute of Science (I.I.Sc), Bangalore and Electricity Dept., Govt. of Manipur. Micro hydel power generation is a viable alternative to extension of grid lines in rural/remote /hill areas. To exploit micro hydel potential on large scale, it is necessary to develop cross-flow turbines suitable for (2x500) kw and more for installation on the river Zoulangpang, Dailong village, Tamenglong district, Manipur. Cross-flow turbine is designed by I.I.Sc. Banglore under a project of DST, GoI. Since the flow of the river varies significantly throughout the year, cross-flow turbine is an ideal option to meet the site conditions on such schemes.

Objectives of the project

1)    To design and develop the cross-flow turbine packages suitable for (2X50) kw capacities. The packages consist of turbines and electronic load controllers for a micro hydel station at Dailong villages.

2)    To study the problems of and set guidelines for installation, operation, maintenance and energy utilization associated with micro hydel units in remote rural hilly terrains. Micro hydel units are environmentally clean and eco-friendly suited to decentralized power generation.
