A second huge power outage across India left 600 million people sweltering in the dark. Gigantic traffic jams, stalled railway trains, closed airports and a general failure of infrastructure services have followed in the wake of what is now the largest power failure in history. Power is being restored across the country at this time.
The outages are being caused by heavy use of electricity due to very high regional temperatures and the ongoing failure of the monsoon, which normally brings wetter and cooler weather to the region at this time of year.
Indian officials were not saying how soon power might be restored, but it is expected that some areas could be without electricity for weeks, due to the extensive nature of the failure.
Temperatures across the Asian subcontinent have been unseasonably high even for midsummer. It is also possible that an incoming coronal mass ejection from the sun may have added to the regional grid overload.
