Chandigarh: Power supply was hit again in Punjab, Haryana and Chandigarh due to collapse of the northern grid, affecting water supply and running of trains.

Although efforts are on to restore normalcy, power officials say it may take at least 3-4 hours to bring power plants back into generation.

"We still don't know what triggered the grid's failure. It will still take 3-4 hours to restore the situation," said K D Chaudhary, CMD of Punjab State Power Corporation Limited.

He said power supply has been restored in few areas and efforts are on to revive electricity in other parts of the state also.

As many as seven northern states had witnessed an almost 15-hour long power crisis after the northern grid collapsed at around 2:30 AM early yesterday.

Meanwhile, Haryana Power Secretary Ajit Mohan Sharan said power supply has been disrupted in the entire state and efforts are on to restore supply. The grid failure has hit almost over 8000 MW of power supply in Punjab and 6500 MW in Haryana.

Power utilities had yesterday claimed that supply would be fully restored by night following failure of the grid at 2:30 AM, but there were several areas in both the states which continued to remain without power.

Both Punjab and Haryana had earlier refused to accept the blame of yesterday's failure of the northern grid due to overdraw of power, as alleged by Delhi government.
