POWERGRID Transmission Network Failure
The Northern Region Grid,which provides Power Supply to 9 States of Northern India including Delhi, experienced a widespread outage due to a grid disturbance that occurred at about 2.35 a.m on 30th 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 at least priority areas like railways, Metro, airports & other essential load could get immediate restoration of power. With the coordinated efforts of the whole team of engineers and constituent state utilities, power supply to the essential services ansd other essential load in Northern India was restored by about 8.00 AM and about 60% of load of the Northern Region was restored by 11:00 AM. This was possible by gearing up the power supply from Hydro sources and also extending power from Eastern & Western Region for startup supply for thermal generating units of 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 PM power supply was extended to most of the cities/towns through POWERGRID substations. The Northern Grid was brought back to normalcy to meet the required demand of about 30,000 MW at 19.00 hrs.
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 a disruption on the previous day. The eastern transmission lines too failed disrupting power supply in Delhi, Uttar Pradesh, Haryana, West Bengal, Assam and Punjab, among other States.
- Independent audit of Grids
Power Minister Veerappa Moily, said that transmission grids will be independently audited in three months to ensure that the grids are fail-safe.

Famous quotes containing the words network and/or failure:
“Of what use, however, is a general certainty that an insect will not walk with his head hindmost, when what you need to know is the play of inward stimulus that sends him hither and thither in a network of possible paths?”
—George Eliot [Mary Ann (or Marian)
“Girls tend to attribute their failures to factors such as lack of ability, while boys tend to attribute failure to specific factors, including teachers’ attitudes. Moreover, girls avoid situations in which failure is likely, whereas boys approach such situations as a challenge, indicating that failure differentially affects self-esteem.”
—Michael Lewis (late–20th-century)
