2003 Italy blackout : ウィキペディア英語版 | 2003 Italy blackout The 2003 Italy blackout was a serious power outage that affected all of Italy—except the islands of Sardinia and Elba—for 12 hours and part of Switzerland near Geneva for 3 hours on 28 September 2003. It was the largest blackout in the series of blackouts in 2003, affecting a total of 56 million people. It was also the most serious blackout in Italy in 70 years. ==Causes==
Power went off at about 03:20 hrs. local time on 28 September 2003. Initial reports from Italy's electricity supplier, ENEL, stated that the power line which supplied electricity to Italy from Switzerland was damaged by storms, causing it to trip and also the two 400 kV power lines between France and Italy to trip due to sudden increased demand from those two power lines. The cascading effect disrupted power supply to Italy from France and Switzerland. ENEL lost control of the grid in the next 4 seconds, with the lines tripped one by one amid the cascading effect. Swiss electricity company ATEL later concurred that a power line between Switzerland and Italy went out for a few hours.
