Middle Tamor Hydropower Project (MTHP), is a run-of river (RoR) project with an installed capacity of 73 MW. The headwork (HW) of the project is located in Phungling Municipality and Phaktanglung Rural Municipality and the Powerhouse (PH) is located in Mikwa Khola Rural Municipality at the right bank of the Tamor River in Taplejung district. The boundary co-ordinates of the project are 870 40’ 01” E to 870 42’ 40” E and 270 23’ 29” N to 270 25’ 19” N. The nearest black topped approach road from the project site is at Bahanande, on the Mechi Highway (233 Km from Charali in Jhapa), 7 km south of district headquarters Phungling Bazar. From Phungling, the project Powerhouse (Thumba village) and Head-works (Mitlung village) sites are accessible via a 15 km and 17 km long separate earthen roads respectively.

The study and design of the Middle Tamor Hydropower Project was completed by the Consultant- Sanima Hydro and Engineering Pvt. Ltd. (SHEPL) and the Generation License was obtained initially for 54 MW on 5 June 2017, and subsequently the design was revised and generation license for revised capacity of 73MW was obtained on 10 December 2018.

Subsequently, Sanima Middle Tamor Hydropower Ltd. (SMTHL) was established as a Special Purpose Vehicle (SPV) Company for the implementation and operation of Middle Tamor Hydropower Project (MTHP). The generation license of 54 MW was transferred from Tamor Sanima Energy Pvt. Ltd to this SPV on 2 November 2017. The generation license for the additional capacity was obtained by the SPV itself.

SMTHL has implemented the construction work with four major individual contract packages of work with different international and national contractors. All of the four major contracts packages (Main Civil Contract, Hydro-mechanical Contract, Electro-mechanical Contract and Transmission Line Contract) have already been awarded by the SMTHL. The Main Civil, Hydro Mechanical and Transmission Line Contractors have been working at the construction site while the Electro-Mechanical Contractor has already started manufacturing relevant equipment at various factories abroad and the first lot of electromechanical equipment has been dispatched from China. The mobilization of the Chinese workers of the EM Contractor is slightly delayed due to COVID-19, however the preparation for their vaccination in China and mobilization at the Project site is underway.

Beside above major individual Contract packages, the pre-construction and preparatory works, which comprises various works like construction of access roads, upgrading of existing earthen road network, road slope protection works, one steel truss bridge and two Bailey bridges across Tamor in Thumba, Lorindin and Mitlung, staff camp facilities at Simle and Lorindin, camp facilities for Nepal Army personnel, bunker for explosives, acquisition of required private lands as well as leasing of public land, arrangements of construction power line and explosives for the tunnel excavation, arrangement of local construction materials and necessary permission form local authorities have been executed outsourcing different suppliers and local contractors on need basis by SMTHL.

According to the Power Purchase Agreement (PPA) with Nepal Electricity Authority (NEA) the required commercial operation date (RCOD) of the Project is 13 September 2021 (28 Bhadra 2078) for 54 MW and 17 July 2022 (1 Shrawan 2079) for the additional capacity.
