Energy Nepal to receive additional 80 MW power
An additional power transfer of 80 MW to Nepal has been expected to commence as of the beginning of the year. With this, the total supply of electricity to Nepal from India will be about 400 MW.
Minister of Energy, Government of Nepal, Janardan Sharma in a recent visit to India, held discussions with Minister of State (IC) for Power, Coal, New & Renewable Energy and Mines, Government of India, Piyush Goyal. Besides reviewing co-operation and expanding ties between the two countries in the power/energy sector, Sharma requested for an additional supply of 80 MW from India to alleviate power shortage in Nepal due to seasonal reduction in supply from domestic hydro projects in the winter months.
Muzaffarpur substation in India
In a swift response to this request – within 20 days– the Power Grid Corporation of India Ltd (PGCIL) installed an additional 220/132kV, 100MVA transformer at the Muzaffarpur substation in India. This transformer will facilitate additional energy supply up to 80 MW to Nepal through the Muzaffarpur-Dhalkebar (Nepal) transmission line. With this augmentation, a total of 160 MW can now be supplied to Nepal through this transmission line.
The electrical grids of India and Nepal are connected through various radial lines at 132kV, 33kV and 11kV voltage levels. Prior to February 2016, as per the request received from Nepal from time to time, various short-term augmentation schemes were carried out, which resulted in the enhancement of power flow to Nepal from 50 MW to about 240 MW.
In February 2016, the Prime Ministers of India and Nepal inaugurated the first high capacity 400kV cross-border line, initially being operated at 132kV, from Muzaffarpur to Dhalkebar. This had resulted in an additional flow of 80 MW, enhancing the total power supply to Nepal to about 320 MW.
The Muzaffapur-Dhalkebar line is planned to be charged at 220kV with the commissioning of 220kV at the Dhalkebar substation in Nepal by March 2017. This will facilitate additional 150 MW of power transfer to Nepal. This will be followed by the commissioning of 400 kV substation at Dhalkebar that would enable operation of the Muzaffarpur-Dhalkebar 400 kV DC line at its rated voltage, leading to increase in power transfer to Nepal by 300-400 MW.
India is also working with Nepal to supply power through two more radial 132kV lines viz. Raxaul-Parwanipur and Kataiya-Kushaha, which are being commissioned through the grant assistance of the Government of India.
India, through PGCIL, has also assisted Nepal in preparation of the electricity Master Plan for Nepal; short term (up to 2018-19); medium term (up to 2021-22) and long term (up to 2035). Accordingly, a number of high capacity cross-border interconnections are being considered between India and Nepal. Initially, these interconnections would be utilised for the transfer of power from India to Nepal and later with the development of hydro projects in Nepal, these links would be utilised for the transfer of surplus power from Nepal to India.
