Completion of this project will facilitate the transmission up to 1,000 megawatts of electricity through Nepals first ever high-voltage cross-border transmission line.

February 12, 2021 – Linxon has successfully commissioned the first 400 kV Gas Insulated Substation (GIS) at Dhalkebar, Nepal on behalf of the Nepal Electricity Authority (NEA). The operation of the Dhalkebar substation is an important milestone for Nepal’s hydropower sector and is the first 400 kV substation to enter operation in the country.

The substation was energised to full capacity, allowing the 400 kV Muzaffarpur (India) – Dhalkebar (Nepal) line to come into operation on November 11, 2020. During an inauguration ceremony on February 1, 2021, NEA has presented a certificate of commendation to Linxon India Private Ltd for the successful completion. The certificate was given by Sh K P Sharma Oli, Hon’ble Prime Minister of Nepal.

Completion of this project will facilitate the transmission up to 1,000 megawatts of electricity through Nepal’s first ever high-voltage cross-border transmission line. The substation, being the major hub for power exchange between Nepal and India, will ease the process of importing power and help meet the increasing demand for electricity in Nepal whilst also facilitating the export of electricity to India when Nepal’s capacity generated is surplus to demand. The operation of the 400 kV Dhalkebar substation will further ease the reliable transmission of electricity within Nepal, along the country’s east-west axis.

“We wish to congratulate NEA on this successful commissioning and thank them for the confidence they have shown in us. We are proud of our collaboration and of the achievements of our execution team in Nepal, who safely steered the project through many challenges to its final completion,” said Frédéric Tréfois, CEO of Linxon.

“Together Linxon and NEA managed to overcome the impact of the COVID19 pandemic as well as a range of infrastructural challenges encountered whilst moving heavy weight consignments,” said Dinesh Chadha, Managing Director of Linxon India. “Nevertheless, these challenges helped us to build a strong collaborative working model between Linxon, our vendors and NEA, and allowed us to demonstrate our tremendous sense of grit and resilience”.

The Linxon scope of supply included testing and commissioning of the high voltage equipment, (15 bays with two bus bars, three 315 MVA transformers and an 80 MVAR reactor) as well as the provision of all necessary civil works associated with the scope.

Linxon commenced operations on September 1, 2018, undertaking turnkey electrical alternating current substation projects related to renewable and conventional power generation, power transmission and transportation solutions. Substations enable the efficient and reliable transmission and distribution of electricity. Within the substation, switchgear controls and protects the network from power outages and facilitates reliable electricity supply.
