tunnel water filling of Upper Tamakoshi Hydroelectric Project – Feedback of Aarambha Group

Pleased to inform that the tunnel water filling of Upper Tamakoshi Hydroelectric Project has been completed successfully last night after observation for 48 hours at its final level(i.e.1987 masl). This is indeed a BIG MILESTONE for the entire project. Today, we are conducting an electrical SOAK test for the first unit and wait for 24 hours of observation prior to synchronization. Similarly, 220 kV transmission line is ready up to Dhalkebar Substation and final 220 kV line-in line-out arrangements at New Khimti Substation is likely to be completed within this week. This will pave the way for synchronization of the first unit (76 MW) to integrated national power system (INPS) and will follow by further load tests. We are thankful to the Contractors Sino Hydro, Andritz Hydro, KEC International, and Consultant JV Norconsult- Lahmeyer for this achievement. We are also thankful to all board members (present and past), financers, all concerned government officials, and all concerned stakeholders for supporting us to accomplish this national pride project.
