Upper Tamor A Hydropower Project is a run of the river hydropower project with the installed capacity of 60 MW. Situated in Taplejung district, the project is a high head project with annual generation of 338.822 GWh. The progress of the project can be summarised in the table below.

Salient Features

Other Information

• The project capacity is 60 MW.
• Upper Tamor A Hydropower Project lies in the Eastern Part and near the China Border
• Access Track from China has already arrived at Olangchungola
• The Government has priority to connect Taplejung with China
• Access Road will reach the project area in near future
• Tamor has very dependable flow, about 30% of the catchment is snow covered
• Its high head project, yet structures are simple to be laid
• The outlet part where most important underground structures are, will be good rock condition

Conclusion

• Recent field visit for the geological study of the project area has shown the overall geological condition of the project suitable for the project
• Surface penstock and powerhouse option were investigated and the result shows that penstock as well as powerhouse can be constructed on surface which will result in significant saving of the cost.
• A new powerhouse location was identified which will increase the head by 100 m making the project’s gross head above 1000 m. This will increase the capacity of the project.
• High head projects are comparatively cheaper than the low head project. Initial study shows that the project cost per mw is around 17 crores per mw. Despite being the project in this location the cost is significantly lower.53
