KATHMANDU: The Samundratar-Trishuli 3B Hub transmission line and substation was inaugurated on Saturday. Prime Minister KP Sharma Oli on Saturday virtually inaugurated the transmission line and the 132/33 kV Samudratar substation in Nuwakot from his official residence at Baluwatar.
The 26-kilometer transmission line starting from Samundratar in Dupcheshwor Rural Municipality of Nuwakot to the underconstruction Trishuli 3B Hub substation in Kispang Rural Municipality will be able to transmit up to 270 MW of electricity. Ten hydropower projects of 60 MW are under construction at different stages with private investment in Tadi River and its tributaries to be connected to this line.
Out of the 26 kilometers transmission line, the three kilometers section is multi-circuit. Out of which, two circuit lines will be used by the 37 MW Upper Trishuli-3B project under construction under the joint promotion of Nepal Electricity Authority and Nepal Telecom under the People's Hydropower Program.
The Samundratar substation has 2 30 MVA transformers of 132/33 kV and 2 8 MVA transformers of 33/11 kV. 5 bays on the 132 side and 4 bay devices on the 33 kV side have been connected and brought into operation. All equipment will be controlled by the modern substation automation system.
As electricity will also be supplied locally from the substation, the problem of reduction of electricity voltage in the eastern part of Nuwakot will be solved. The total cost of the transmission line and substation constructed with the investment of the Government of Nepal and concessional loans from the Asian Development Bank (ADB) and the European Investment Bank (EIB) is Rs 1.55 billion.
A contract agreement was signed with ETERN CCCE FEPEC Joint Venture, China on November 28, 2020 for the construction of the transmission line under NEA Project Management Directorate. The substation is spread over 33 ropanis of land. 21 ropanis of land and 948 ropanis of land under the wire have been used for the transmission line tower.
