India’s power supply has been fully restored after a two-day blackout hit much of the country, officials say.
More than 600 million people were affected by the power cut after three electricity grids collapsed, one for a second consecutive day.
The power failure caused havoc, with whole cities grinding to a halt and transport and other services badly hit.
The breakdowns in the northern, eastern and north-eastern grids affected 20 of India’s 28 states.
Power System Operation Corporation chief SK Soonee said electricity had been restored in all three grids overnight on Tuesday by engineers from the state-owned company.
The blackout caused chaos on transport networks with hundreds of trains stranded and water supplies interrupted.
In Delhi, Metro services were halted and staff evacuated trains. Many traffic lights in the city failed, leading to massive traffic jams.
Other areas affected included Punjab, Haryana, Uttar Pradesh, Himachal Pradesh and Rajasthan in the north, and West Bengal, Bihar, Orissa and Jharkhand in the east.
In the eastern state of West Bengal, around 200 miners were trapped underground as lifts failed, but officials later said they had all been rescued.
One shopworker in Delhi, Anu Chopra, 21, said: “I can understand this happening once in a while but how can one allow such a thing to happen two days in a row?
“It just shows our infrastructure is in a complete mess. There is no transparency and no accountability whatsoever.”
