Three 220kV substations come into operation in eastern NepalThese stations would improve voltage, enhance the quality of power supply, and resolve tripping problem, Nepal Electricity Authority says.
The Nepal Electricity Authority brought three 220kV substations in eastern Nepal into operation on Thursday. These substations will enable the transmission of power from projects developed in the hilly regions of Province 1.
Of the three substations, one is located at Inaruwa in Sunsari district and the remaining two at Tumlingtar and Baneshwar in Sankhuwasabha district, according to the power utility.
Along with the operation of these substations, the 220kV Inaruwa-Tumlingtar transmission line, which is a part of the Koshi Corridor Transmission Line Project, was also charged, the power utility said, adding that these substations would improve the voltage of power and enhance the quality of electricity supply.
“There was the issue of voltage and tripping (shutting off of the electrical flow to protect the circuit from overheating) in electricity supply in the Morang-Sunsari Industrial Corridor as electricity was being supplied through the Sunsari-based Duhabi substation only,” Kul Man Ghising, managing director of the Authority said in the statement. “Tripping was a recurrent issue in electricity supplied from power projects in Sankhuwasabha, Bhojpur and Tehrathum. The operation of the new substations will resolve these problems.”
Ghising said electricity coming through the Koshi corridor could also be exported to India through the Dhalkebar substation in Dhanusha in the Madhesh province. A 23-km 132kV transmission line from Inaruwa to Biratnagar and additional substations along this transmission line are also under construction to improve the electricity supply in the Sunsari-Morang industrial corridor, the Authority said. The industrial corridor houses around 5,000 factories which provide direct employment to around 50,000 people.
The Inaruwa-based substation was built with the financial assistance from the World Bank while the government took loans from the Indian Exim Bank to build the other two substations in Sankhuwasabha.
The electricity generated by the projects constructed on the Arun and Tamor rivers and their tributaries will be evacuated through the Koshi Corridor transmission line and sent to the Inaruwa substation, according to the Nepal Electricity Authority.
The Authority has signed power purchase agreements with the developers of 357 projects whose combined installed capacity is 6,366MW, according to the power utility body. Energy Minister Pampha Bhusal early this week said that the projects with a combined capacity of 3,200MW are currently under construction.
But constructing transmission lines to evacuate power from these projects has emerged as a major challenge with local obstructions and prolonged court cases, according to the officials of the Authority.
Dirghayu Kumar Shrestha, chief of the Transmission Line Directorate told the Post in March: “Acquiring land for transmission towers and the right of way for transmission lines is difficult because they cover several districts. There has been a tendency among the local people to create problems,” said Shrestha.
According to him, getting the right of way for transmission lines is one of the major challenges.
“Landowners don’t get full compensation for the right of way,” said Shrestha. “The value of the land with transmission lines running overhead decreases sharply because such land cannot be used for any other purpose than farming. Banks also don’t accept such land as collateral. People, therefore, often do not want to provide the right of way.”
