1 PROJECT INFORMATION AND SHORTLISTING CRITERIA FOR SCREENING OF CONSULTING FIRM 1. PROJECT INFORMATION Intoduction: Tamakoshi V Hydroelectric Project The Tamakoshi-V Hydropower Project is a cascade development of the Upper Tamakoshi HEP with tandem operation. The project area is located on the right bank of Tamakoshi River. This project does not need separate headwork. It takes the discharge from the tailrace of the Upper Tamakoshi Project through an underground inter connection arrangement and conveyed to headrace tunnel of this Project. An underground powerhouse is proposed at Suri Dovan. The design discharge of the project is 66 m3/sec and has installed capacity of 87 MW. The general arrangement of the project comprises of underground interconnection arrangement of headrace tunnel with the tailrace tunnel of Upper Tamakoshi HEP. The interconnection system consists of connecting tunnel, a head pond required to maintain suction head at the pressurized head race tunnel entrance, spillway and spillway tunnel. The water from tailrace of Upper Tamakoshi HEP is diverted to this interconnection system and conveyed to the 8.20 Km long concrete lined headrace tunnel, a m high drop shaft, m long pressure tunnel, m long tailrace tunnel, m long tailrace canal and underground powerhouse containing four vertical axis Francis turbines, from where it is released into the Tamakoshi river at about 0.2 km downstream from the confluence of Tamakoshi River and Khari Khola at Suri Dovan. Location and Access: Tamakoshi-V is located in the Central Development Region of Dolakha District of Janakpur Zone. The project area is situated within Longitude 86 o to 86 o East and Latitude 27 o to 27 o North. The whole project area lies in Khare, Orang and Lamabagar Village Development Committees. This project is conceptualized to develop as a tendon operation project with Upper Tamakoshi HEP. The intake site / underground interconnection system with Upper Tamakoshi tailrace outlet is located in Lamabagar VDC at an elevation of m whereas the underground powerhouse lies at the right bank of Tamakoshi River just downstream of the Suri River confluence with Tamakoshi River. The Tamakoshi-V Hydropower Project is located approximately 170 km north east of Kathmandu, the capital of Nepal and approximately 40 km away from the district head-quarter of Dolkha District- Charikot Bazaar. The district head-quarter is connected with the capital by Arniko Highway upto Lamasangu which is approximately 90 km and by Lamasnagu Jiri road which is approximately 40 km up to Charikot. A gravel road of about 33 km is available from Charikot to Singate Bazaar is recently upgraded for the construction of Upper Tamakoshi Project. The newly constructed road connecting Singate Bazaar and Lamabagar for the construction of Upper Tamakoshi HEP passes from the both powerhouse and the headwork sites of this project. This road is recently built. Salient Features: Location of project Village Development Committee Cascade development of Upper Tamakoshi HEP Khare, Orang and Lamabagar VDCs
