1.0 Abstract of the Project:
Micro Hydel Power Generation is a viable alternative to extension of grid lines in rural/remote/hilly areas. To exploit micro hydel potential on large scale, it is necessary to develop cross-flow turbine suitable for (2 x 50) kW and more for installation on the rivers/streams in the hills.. Since there is a very good perennial source of water in the Zoulangpang river, Dailong Village, Tamenglong District, therefore cross-flow turbine is an ideal option to meet the site conditions in the implementation of such schemes in the State of Manipur

1.1 Advantages of Cross-flow Turbine:

Good efficiency even on part loading conditions.
Need for thrust bearing is eliminated since the discharge crosses through the turbine.
Manufacture and erection of the turbine is easy.
Because of less weight, transportation of cross-flow turbines is easier.
Since the discharge crosses through the turbine, it adds up to self-cleaning property to the turbine.
Suitable for wide range of flow and head.

2.0 Project Site :
The project was implemented at Dailong village, Tamenglong District, Manipur over the Zoulangpang Stream. Dailong viallage is situated at about 160 km from the State Capital, Imphal and 12 kms from Tamenglong District Headquarters towards Tamei in the Tamenglong-Tamei Road.
