The Northern and Eastern Grids tripped on Tuesday,
leading to power failure in several states of the country affecting hundreds of millions of people.
Power supply was disrupted in Delhi, Uttar Pradesh, Haryana, West Bengal, Assam and Punjab, among other states.
While the Northern
Grid collapsed for the second time in two days, the Eastern
transmission lines too failed this afternoon, said officials at the Power Ministry and electricity companies.
