600 million people without electricity
A massive power cut hit India on Tuesday, leaving 600 million people without electricity in one of the world's most widespread power failures.
The outage came just a day after India's northern power grid collapsed for several hours leaving cities and villages across eight states powerless.
Indian officials managed to restore the northern grid by Monday evening, but at 1.05pm Tuesday the grid collapsed again, said Shailendre Dubey, an official at the Uttar Pradesh Power Corp. in India's largest state.
About the same time, the eastern grid failed as well, said SK Mohanty, a power official in the eastern state of Orissa.
The two grids serve about half India's population.
The power failures have raised concerns about India's outdated infrastructure and its insatiable appetite for energy that the government has been unable to meet.
