Large parts of South Delhi went without power for almost seven hours on Tuesday. The electricity failed at 12.30 pm, to be restored only after 6.30 pm and later in some areas. Indira Gandhi International Airport was affected too.
Delhi Transco, which mans the grid network for power transmission in the city, said it had restored the two lines but imposed load restrictions. “That means there would be frequent power outages on Wednesday too,” sources said.
The outage occurred after two 220 kilovolt transmission lines from Badarpur and Mehrauli tripped almost simultaneously. A third line from Mehrauli to Bamnauli had already been shut down to install a transmission tower — intended, ironically, to ensure uninterrupted power supply to the airport.
A host of upmarket areas — Vasant Vihar, Vasant Kunj, Alaknanda, Chittaranjan Park, Hauz Khas, Saket and Mehrauli among them — were affected.
Though power supply to the airport was quickly restored, there were fluctuations through the day. “There were problems till 2 p.m. The fluctuation badly affected work,” said a senior airport official.
“The lines tripped unexpectedly,” said a Delhi Transco official. “And because of the planned shutdown of a third line, the situation went out of hand.”
“I returned home from work at 1 p.m. and there was no power. The weather outside was horrible and indoors too it was boiling,” said Sutapa Choudhury, a resident of Chittaranjan Park.
Transco officials claimed they restored transmission lines by 6.30 p.m. following which some areas started receiving power supply. “It takes time for power supply to normalise. It was around 7 p.m. that most parts of South Delhi started getting power,” said the official.
