CAUSES Power went off at about 03:20 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 400Kv 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. EFFECTS The night of 27 September 2003 is the night of the annual overnight White Night Carnival in Rome , the capital of Italy. Thus, many people were on the streets and all public transportation were still operating at the time of the blackout (at about 3am on 28 September 2003 ) despite the fact that it was very late at night already. The blackout caused the carnival to end early. Several hundred people were trapped in Underground trains. Coupled with heavy rain at the time, many people spent the night sleeping in train stations and on streets in Rome. Throughout Italy, 110 trains were cancelled, with 30,000 people stranded on trains. All flights in Italy were also cancelled. Police described the scene as chaos but there were no serious accidents. The blackout, however, did not spread further to neighbouring countries, such as Austria , Slovenia and Croatia , which are connected to Italy. Only part of the Geneva Canton of Switzerland suffered a power outage for three hours. RESTORATION OF SERVICE Nine hours later, in the afternoon of 28 September, electricity was restored gradually in most places, including Turin , Milan , Venice and Rome . Rolling Blackout s continued to affect about 5% of the population on the next two days (29-30 September) when the electricity company ENEL continued its effort to restore supply.
