There was no power in areas like Dwarka, Rohini, Jahangirpuri and some parts of east and outer Delhi. Power department officials said this morning that it will take another 3-4 hours to repair the power line to restore normal electricity supply in these areas.
The affected residents expressed anger over failure of concerned agencies to repair the power network which also affected water supply in these areas, adding to the residents' woes in the summer heat.
A powerful dust storm had struck the city at around 4:58 PM yesterday throwing normal life out of gear, severely damaging the entire power transmission network in Delhi and neighbouring states. At least nine people were killed in the NCR region, including six in Delhi, in incidents of falling trees, collapse of walls and electrocution.
Two major 220 KB transmission lines from Pamnouli to Papankallan and Bawana to Rohini grid were severely damaged in the storm because of which supply of power could not be restored in various areas of west Delhi, said a senior power department official.
