Local time At around 2:30 on July 30, 2012, a failure of an EHV transformer substation in Uttar Pradesh, India, led to overload of some transmission lines and substations, followed by a chain reaction that eventually led to the collapse of the entire northern power grid. Outage covers the northern region of India, affecting the power supply load 35.67 million kilowatts (the whole network load of about 200 million kilowatts). After about 15 hours of repairs, 80% of black-out users’ electricity was restored.
