Nepal substation completed two years after deadline

Almost two-and-a-half years after the scheduled deadline, the 220 kV substation of Dhalkebar has been finally completed, which will ensure reliable power trade between Nepal and India.

This substation is one of the components of Dhalkebar-Muzaffarpur cross-border transmission line, which was supposed to be completed by September 2015. However, a dispute between the original contractor and the Nepal Electricity Authority (NEA) prolonged the project’s finalization.

Later, towards the end of 2017, NEA had terminated the contract and awarded the bid to Telmos Electronics, India.  The substation project is supported by the World Bank Group.

NEA had earlier been importing power from India through a temporary substation that was established after leasing transformers from India as a temporary vehicle for electricity import. NEA has an agreement with NTPC Vidyut Vyapar Nigam of India to import 145 megawatts of round-the-clock energy and the current import stands at around 100 megawatts. However, the temporary arrangement lacked adequate protection and witnessed fluctuations in voltage and tripping.

According to Prabal Adhikari, spokesperson for NEA, transformers installed in substation have already been charged and substation is ready to transmit power. Power trade of up to 1,000 megawatts is viable via the Dhalkebar-Muzaffarpur transmission line along with completion of the substation.

NEA has plans to upgrade the Dhalkebar substation to 400 kV capacity.
