KATHMANDU: Home Minister Ram Bahadur Thapa has expressed concern over the issue of disruption in power supply to Tribhuvan International Airport (TIA), country's sole international airport. Minister Thapa today summoned Nepal Electricity Authority (NEA) executive director Kulman Ghising to his office and directed him to take measures to address problems seen in the power supply to TIA. The Home Minister insisted on the need to address the issue as chances of illegal business and activities are high in immigration and other bodies in the absence of continued power supply, promising all possible help from the government towards that end. Disruption in airport's power supply system for even a brief time may cause big problems, he said, directing the NEA chief to pay special attention to the matter. In response, NEA executive director Ghising said, problems in power voltage sometimes caused minor problems in power supply to the airport, adding that the NEA was serious about it. He promised to take all possible measures to avoid such situation in the future. 'The NEA efforts will be for providing uninterrupted power supply to TIA, hospitals and other emergency areas.' He took the time to call on the Home Minister to provide necessary help to NEA for controlling power leakage.
