400 KV Dhalkebar Substation Completed | PM Oli To Inaugurate The Substation On Magh 19

February 1, 2021 | Investopaper

The construction of Dhalkebar substation, the country’s largest substation, has been completed. Prime Minister KP Sharma Oli will inaugurate the substation on February 1 , 2021 [Magh 19, 2077 BS].

The substation is currently the largest in operation in Nepal. All the tests have been completed by charging the additional power transformer of 315 MVA connected to the substation.

At present, two 160 MVA and one 315 MVA 635 MVA transformers are connected in Dhalkebar. Similarly, the substations with a total capacity of 400 and 220 KV have three 315 MVA capacity and three 945 MVA capacity power transformers, which can transmit about 900 MW of electricity. The substation is also an automatic substation with GIS technology.

The substation was first charged at 132 KV in Magh 2072 BS. After that, a total of 80 MW of electricity was imported from India. Similarly, in 2074 BS, the substation was charged at 220 KV. As the Dhalkebar-Muzaffarpur transmission line, constructed as the Nepal-India interstate transmission line, has a capacity of 400 KV, a highway has also been constructed for exchanging electricity.

After the completion of the project, the way has been paved for the exchange of 1,200 MW of electricity from both Nepal and India. Electricity of Upper Tamakoshi with a total capacity of 456 MW will also be connected to the same substation.

According to NEA, Dhalkebar substation can now be operated at 132, 220 and 400 capacity. Similarly, electricity can be transmitted from East-West as required. As the construction of Upper Tamakoshi and other projects will be completed in the current fiscal year, the way has been paved to send wasted electricity to India during the rainy season.

India has agreed to provide additional 100 MW power from Dhalkebar Muzaffarpur 400 KV transmission line. Nepal can bring 400 MW of electricity from the inter-country transmission line.

NEA and Indian company NTPC Vidyut Nigam Limited (NVVN) have signed an agreement to purchase up to 250 MW of electricity through the Dhalkebar-Muzaffarpur transmission line in July-November, up to 350 MW in December-April and up to 200 MW in May-June. The PPA is valid till June 30, 2021.

As the demand for electricity has increased in the current dry season, more electricity is being imported for management. According to NEA, a total of 6,369 MW of electricity is being generated from NEA’s projects at present.

Similarly, the project of private energy entrepreneurs is generating 5,375 MW of electricity. Similarly, the electricity being imported from India is 14,458 MW per hour. The total demand is 26,202 hours. Calculated in MW, the total demand is 1,464 MW.
