While residents didn’t just have the inconvenience of no power. Roads ground to a halt as traffic lights stopped working. Hospitals without backup generators had to postpone major surgery and scheduled operations. AroundĨ0 electric trains were stranded on tracks for 15 hours, blocking the lines untilĭiesel-powered trains came to the rescue and move them out of the way. Such widespread loss of power caused understandable chaos. Nearly a quarter of the country’s populace (230 million) were left in the dark It affected six states and the capital New Dehli, while On this occasion, a failure at the Uttar Pradesh substation kickstartedĪ collapse of the whole grid across the north of the country. We’re heading back to India for our next big blackout, which at the time was the largest ever on record. India Blackout 2 January 2001 (affected 230 million people) ![]() Investigations following the failures recommended a $400 billion strategy to revamp and update the grid to prevent such incidents happening again. For context, this figure represented roughly 9% of the entire world’sĭespite their massive reach, both incidents were resolved relatively quickly with electricity restored to most areas by 1 August. The outage hit 620 million people, more than half of India’s The resulting blackout affected 22 out of 28 states in the north and Several power plants to disconnect from the grid.Īpproximately 38% of India’s power generation capacity went It was caused by a relay problem near the Taj Mahal, which forced To this day, 31 July 2012 is the world’s biggest-ever powerįailure. But it was dwarfed by the following day’s As this line fed into the transmission section of the network, it had a knock-on effect throughout the grid.Īs a result, all power stations in the affected areas closedĭown, causing a 32 GW shortage that left around 400 million people withoutįor a few brief hours, this was the largest ever blackout rankedīy the number of people affected. The first of the failures occurred on 30 July, when circuit breakers tripped on the Bina-Gwalior line. But they provided the backdrop for a pair of power events Whether these conditions were a direct cause or not wasn’t While the lack of rain led to greater power consumption to run pumps to irrigate paddy fields in the agricultural areas of Punjab and Haryana. The monsoon season also arrived later than usual, meaning hydropower plants were under capacity. Power generation often fell short by around 10%.Įxtreme heat during the summer of 2012 saw power use reach record levels in the capital New Dehli. While during the highest periods of demand, Its northern electrical grid collapsed completely in 2001.Įstimates suggest the country lost more than a quarter of However, its electrical infrastructure is notoriously unreliable and large-scale power outages are regular events. ![]() Topped by only the United States and China, India is the world’s third-biggest producer and consumer of electricity. The end of July saw India struck down by what were the biggest and second-largest power cuts ever. India Blackout 30-31 July 2012 (affected 620 million people) Here are the biggest blackouts in history according to the sheer number of people left in the dark. These following examples are proof that a nationwide grid shutdown shouldn’t be seen as an “ impossible” event. the Blackout report explores what could cause these more serious failures. Sometimes power cuts can have a much wider impact. But they’re over fairly quickly with limited damage. Sure they’re inconvenient for the hundreds or perhaps thousands Some might even be caused by something as innocuous as an animal chewing through a cable. And when they do happen, more often than not, they’re relatively localised incidents. In developed societies such as the UK, power cuts are rare. Counting down some biggest blackouts the world has ever seen including electrical interruptions that left hundreds of millions of people in the dark.
