Construction of New Butwal substation nearing completion

Planned to be completed and bring into operation by this March, the construction of New Butwal substation at Sunwal of Nawalparasi is nearing completion.
According to the Nepal Electricity Authority, the substation is part of the move to reinforce the transmission system to facilitate bilateral and regional power trade, and enhance the national grid for domestic energy distribution.
“The project will be completed within the targeted time,” Nepal Electricity Authority (NEA) managing director Kulman Ghising said, after a visit of the construction sites. Taking updates of the project with the the contractor company, he directed to complete the project within time. “Only the installation of the equipment is left," he said, asking to complete the civil structures and focus on the installation of equipment. “The NEA is there to help whenever there is any problem.”
“After the substation comes into operation, the technical leakage will be reduced by 4 per cent to 5 per cent, Ghising said, adding that the consumers will get reliable and sufficient power supply, and the problem of power cuts during summer will also be solved.
The Indian contractor Tata Project Ltd is planning to operate the substation by mid-April. The state power utility plans to evacuate electricity generated by schemes in the Kali Gandaki River basin through 220KV Kaligandaki Corridor transmission to New Butwal substation and to the national grid. The New Butwal substation aims to promote domestic power consumption and cross-border or regional electricity trade.
The second cross-border transmission line for electricity trade between Nepal and India will start from New Butwal substation. Nepal and India have agreed for electricity trade, construction, and implementation of New Butwal-Gorakhpur 400kV double-circuit transmission line. Built in about 20 bighas of land, New Butwal will be the second largest electricity hub after Dhalkebar substation at Dhanusha.
According to a report by the National Renewable Energy Laboratory’s Strategic Energy Analysis Centre of the US, Butwal in south-central Nepal is strategically located for cross-border energy trade between India and Nepal because of its proximity and ability to connect with India’s Uttar Pradesh state and the Northern Regional Load Dispatch Centre via Gorakhpur where power demand is high during the monsoon.
New Butwal substation is also the starting point of the second high capacity transmission link between Nepal and India for bulk movement of hydroelectricity. Another 400kV substation has also been planned at the site for cross-border energy exchange.
The government will construct another substation with a capacity of 400kV will be built at New Butwal from the grant provided by the US through Millennium Challenge Corporation (MCC). The MCC will also build transmission line from Damauli of Tanahun to New Butwal.
Electricity transmitted through 132kV transmission line from Hetauda of Makwanpur to Bharatpur will be supplied to the area after trapping the electricity at East Chitwan substation.
Nepal and India – in October – agreed to fund the transmission line connecting Butwal to Gorakhpur in India through a commercial entity with both countries pledging equal entity in the funding of the project. The proposed transmission line is also a major component of the $630 million Nepal Compact, an agreement between the government of Nepal and Millennium Challenge Corporation of the US, which has stirred political controversy in Nepal.
Millennium Challenge Account-Nepal, the implementing agency of the transmission and road projects under the US grant, plans to set up a 400 kV transmission line from Damauli in Tanahu and connect it to New Butwal substation.
Also, the Nepal Electricity Authority is building a 220 kV Bardaghat-Butwal transmission line financed by the World Bank (WB) another 400 kV link to western Nepal, from Butwal to Kohalpur and to Upper Karnali via Surkhet, has been proposed to be built with preparatory studies ongoing under a $21 million grant from the Asian Development Bank (ADB).
Nepal is currently trading up to 250 megawatts of electricity with India through the Dhalkebar-Muzaffarpur setup, and work is underway to upgrade Dhalkebar substation to 400kV capacity in a bid to relay a larger amount of power. The move is also expected to allow the two countries to run their electricity grid in synchronous mode, and facilitate a smooth and reliable flow of electricity.
