At 02:35 IST (21:05 UTC on 29 July), circuit breakers on the 400 kV Bina-Gwalior line tripped. As this line fed into the Agra-Bareilly transmission section, breakers at the station also tripped, and power failures cascaded through the grid. All major power stations were shut down in the affected states, causing an estimated shortage of 32 GW. Officials described the failure as "the worst in a decade".On the day of the collapse, Power Minister Sushilkumar Shinde stated that the exact cause of the failure was unknown, but that at the time of the failure, electricity use was "above normal". He speculated that some states had attempted to draw more power than permitted due to the higher consumption. Spokesperson for PowerGrid Corporation of India Limited (PGCIL) and the Northern Regional Load Dispatch Centre (NRLDC) stated that Uttar Pradesh, Punjab and Haryana were the states responsible for the overdraw. PGCIL's chairman also stated that electrical service was restored "at a record time".A senior director for an Indian power company described the outage as "a fairly large breakdown that exposed major technical faults in India's grid system. Something went terribly wrong which caused the backup safety systems to fail."More than 300 million people, about 25% of India's population, were without power. Railways and some airports were shut down until 08:00. The busiest airport in South Asia, Delhi Airport, continued functioning because it switched to back-up power in 15 seconds. The outage caused "chaos" for Monday morning rush hour, as passenger trains were shut down and traffic signals were non-operational. Trains stalled for three to five hours. Several hospitals reported interruptions in health services, while others relied on back-up generators. Water treatment plants were shut down for several hours, and millions were unable to draw water from wells powered by electric pumps.The Associated Chambers of Commerce and Industry of India (ASSOCHAM) stated that the blackout had "severely impacted" businesses, leaving many unable to operate. Oil refineries in Panipat, Mathura and Bathinda continued operating because they have their own captive power stations within the refineries and do not depend on the grid.It took 15 hours to restore 80% of service.
