Inaruwa substation inaugurated: A crucial milestone in Nepal’s electricity transmission and distribution system

KATHMANDU: Prime Minister Pushpa Kamal Dahal inaugurated the state-of-the-art 400 kV Inaruwa Substation on Friday, a significant addition to Nepal’s power infrastructure. The inauguration ceremony took place in Bhokraha Narasimha Rural Municipality-4, Sunsari, symbolizing a key milestone in the government’s commitment to enhancing the country’s electricity transmission and distribution system.

Constructed under the National Electricity Development Decade Program, the Inaruwa Substation, based on the Gas Insulated Switchgear (GIS) system, is the second-largest 400 kV substation in the country.

It follows the successful inauguration of the Dhalkebar 400 kV substation. The substation is part of a joint investment by the Government of Nepal and the Nepal Electricity Authority (NEA).

Two substations, with capacities of 400 kV and 220 kV, have been built in Inaruwa, supported by a concessional loan from the World Bank. The total cost of these substations is approximately NPR 3.83 billion.

These infrastructural developments contribute significantly to the establishment of the Nepal-India electricity transmission and trade arrangement, forming a backbone with ratios of 220:132:33 kV.

During the inauguration ceremony, Prime Minister Dahal highlighted the substation’s potential to transmit around 4,000 megawatts of electricity, marking a new chapter in the government’s “Ujayaalo Nepal” program.

He stressed the positive impact of completing such crucial projects amid national discussions, contributing to the overall development of the nation.

The Prime Minister also addressed key issues related to land distribution and forest development, expressing the government’s commitment to resolving these matters. He emphasized the importance of fostering development and good governance in the coming years.

Koshi Pradesh’s Chief Minister Kedar Karki expressed confidence in the resolution of electricity supply disruption issues caused by the operation of substations. He underlined the province’s commitment to both physical and human development, emphasizing the collaboration with the private sector.

Kulman Ghising, the Executive Director of the Nepal Electricity Authority, explained the electricity generation and transmission activities in various districts of Koshi Pradesh.

He highlighted the export of surplus electricity to India through the Inaruwa Substation, showcasing its critical role in improving voltage quality and ensuring reliable electricity supply, fostering trade relationships with neighboring countries.

The completed Inaruwa-Dhalkebar 400 kV transmission line enhances the Inaruwa Substation’s capability to transmit significant electricity, meeting the rising demand in the Morang-Sunsari industrial corridor.

The collaborative effort with Indian companies, including Siemens Limited and Telemos for the construction of substations, underscores the commitment to quality and efficiency in Nepal’s power infrastructure projects.

The design and construction supervision by Indian company NEA Engineering, along with consultancy services by Power Grid Corporation of India Limited and NEA Engineering Company, further ensure the success and sustainability of these projects.
