transmission network failure edit main article july 2012 india blackout the northern region grid which provides power to nine states in northern india including delhi experienced a widespread outage due to a grid disturbance that occurred at about 2.35 a.m on 30 july 2012 . restoration work started immediately under the direction of ceo posoco and powergrid s chairman & managing director . a team of engineers tried to find out a way for restoring the normal supply of power immediately so that railways metro airports and other power users deemed essential could get immediate restoration of electricity . with the coordinated efforts of the whole team of engineers and constituent state utilities power supply to the essential services and other essential loads in northern india was restored by about 8.00 a.m. and about 60 % of load of the northern region was restored by 11 00 a.m. this was possible by gearing up the power supply from hydroelectric sources and also extending power from the eastern and western regions for start up supply for thermal generating units of the northern region . thus the associated problems for want of power supply could be partially overcome by this time . later power supply was restored progressively and by 12 30 p.m. power was extended to most of the cities and towns through powergrid substations . the northern grid was brought back to normalcy to meet the demand of about 30 gw at 7 00 p.m. on 31 july 2012 the northern grid collapsed for a second time hours after the power supply was restored in the entire northern region following
