Flight operations at Delhi airport remained unaffected even as power failed for a second day in a row on Tuesday afternoon. As soon as the power supply snapped at 1-04 p.m., all the essential services at the airport were shifted to diesel-run power back-up system.
“There was a failure in power supply from the discoms. However, flight operations at Indira Gandhi International Airport were absolutely normal and there were no cancellations or delays. The entire power load of the airport was restored within 15-60 seconds. This was made possible by an extensive arrangement of power back-up and multiple redundancies put in place by DIAL,” said a Delhi International Airport Limited (DIAL) spokesperson.
“The back-up system offers complete, multiple redundancy ensuring that critical lighting on runways, taxiways and elsewhere on the airside is never compromised. Diesel generated sets are being used to run all facilities at the airport and discom’s power will be used once it is restored and frequencies checked for aberrations,” the spokesperson added.
The total installed capacity of the back-up system at Delhi airport is 59.5 MW, which is well in excess of actual loads claimed the spokesperson.
Flight services remained largely unaffected even on Monday after the Northern Grid collapsed.
