Capacity of Dhalkebar substation increased
Nepal, Kathmandu: The capacity of Dhalkebar substation, the country’s largest substation in Dhanusha, has been expanded.
The Nepal Electricity Authority (NEA) has added 220/132 kV, 315 MVA capacity power transformer in Dhalkebar under the Grid Substation Capacity Expansion Project with the government investment.
NEA’s officiating managing director Hitendra Dev Shakya informed that an additional 315 MVA power transformer connected to the substation was charged on 3 December. At present, two 220/132 kV transformers with the capacity of 320 MVA are in operation at Dhalkebar substation. Now, the capacity of the substation has reached 635 MVA. Of the two 315 MVA transformers to be connected to Dhalkebar under the Grid Substation Capacity Expansion Project, one has been already charged while another one is in the process of being connected.
“As soon as the 315 MVA transformer is charged, an additional 100 MW of electricity can be imported from India in winter and supplied to meet the domestic demand. And after the 456 MW Upper Tamakoshi comes into operation, the infrastructure is ready to export electricity that cannot be consumed at home,” said Shakya.
The 400/220 kV Dhalkebar substation, which came into operation a few months ago, has three power transformers with a capacity of 315 MVA each and a total of 945 MVA capacity, which can transmit about 900 MW of electricity. According to Dirghayu Kumar Shrestha, chief of the NEA’s Broadcasting Directorate, if necessary, an additional 100 MW of electricity can be imported through the Dhalkebar-Muzaffarpur cross-border transmission line as per the agreement reached with the Indian side.
The NEA and Indian company NTPC Vidyut Vyapar Nigam have signed a power purchase agreement for Dhalkebar-Muzaffarpur transmission line of up to 250 MW during July-November, 350 MW during December-April and up to 200 MW in May-June. The PPA is valid till 30 June 2021.
