2.52pm: Power supply has been restored to almost 80 percent of the the national capital area, according to officials.
“Power supply has been restored in nearly 80 percent of Delhi,” an official from Delhi power supplier BSES told IANS.
According to Power Minister Sushilkumar Shinde, nearly 60 percent of electricity supply had been restored to North India, and efforts to restore the power supply were on “on a war footing”.
VV Sharma, general manager of Power System Operation Corporation Limited (PSOCL), told IANS that restoration was on and the situation was now “good” in most states.
He said a three-member committee had been appointed for looking into the reasons of the failure. Exact details would be given only after the committee came out with its report, Sharma said but did not give a timeline.
“The trouble resulted in power outage in the entire northern region, but for parts of Badarpur in south Delhi, Narora and Simbhauli in Uttar Pradesh and Bhinma in Rajasthan,” a statement from PSOCL said.
According to a Northern Railway spokesperson, nearly 100 trains were disrupted but traffic was back to normal by 8 a.m. Around 45 local trains in Delhi was also effected.
“Power supply has resumed, but several trains are plying four-five hours late. We are holding back goods trains and giving priority to passenger trains,” the spokesperson said.
“On priority basis the vital services and VIP areas were first provided power, most of the services have now been restored,” a BSES official told IANS.

11.09am: Union Minister for power and energy Sushil Kumar Shinde has said that 60 percent of power has been restored to the Northern grid, and said he has appointed a three-member committee to probe what had caused the entire Northern grid to fail, plunging nine states into crisis.
“The reason for the outage was due to some states taking more power than they ought to have, which causes the frequency rate of the grid to go up. The offending states will be severely penalized”, Shinde told a gathering of reporters. However he said that the committee would investigate if there were any other reasons for the outage.
Shinde added that once the Northern grid had gone down, they began borrowing power from the Western and Eastern grids in order to provide power supply to emergency services.
The Minister was also quick to point out that the failure was an aberration, saying that India had one of the best power grids in the world. He also said that unlike the last time an outage of this nature occurred it took a mere six hours to begin restoring power as opposed to 16 hours before.
10.42am: Almost all Shatabdi and Rajdhani trains are delayed by over 4 to 5 hours in North India as a result of the breakdown.

The trains affected include the Amritsar Delhi Shatabdi Express, Allahabad Chandigarh Unchahaar, Lucknow Chandigarh Sadbhavna, Howraha Kalka Mail, Delhi Jammu Mail and a number of other super fast, express, passenger and local trains.
Meanwhile power is slowly being restored to the seven states affected by the breakdown in the national grid. Power has been partially restored to Delhi, Haryana, Punjab, Jammu and Kashmir, Uttar Pradesh and Himachal Pradesh.
Distribution companies are now supplying power on a priority basis, with hospitals and the Delhi Jal board getting first preference. However it will still take a few more hours for power to be completely restored across all nine states. Union minister for power and energy, Sushil Kumar Shinde said about 40% power had been restored across the region.
10.35am: Five of Delhi’s six water treatment plants are now operational. Power companies are giving priority to the Jal Board and its pumping stations to restore water to the city.

10.07am: Power is being slowly restored across North India, but officials estimate that the situation will only fully return to normal by evening. Union power minister Sushil Kumar Shinde said about 40 percent power had been restored, including to emergency services.

“We have one of the best DG (Diesel Generating) back-up system of the world. However, there might be some disruption in our non-essential services”, he added.
