西班牙和葡萄牙周一发生大规模停电，公共交通系统、交通信号灯、医院、制造业和核电站均受到影响。
据报道，从马德里到里斯本都出现了停电，截至周一下午早些时候，伊比利亚半岛大部分地区停电。
西班牙输电系统运营商Red Eléctrica的负责人爱德华多·普列托表示，此次停电是由于“电网发生非常强烈的震荡”，导致西班牙电力系统“与欧洲电力系统断开，伊比利亚半岛电网于12:38崩溃”。
普列托拒绝猜测导致电涌的原因，也拒绝透露网络攻击是否是导致停电的原因。虽然西班牙部分地区已经恢复供电，但他补充说，全国其他地区完全恢复供电需要6到10个小时。
欧盟委员会执行副主席、前西班牙政府高级部长特蕾莎·里贝拉表示，“目前没有任何证据表明存在任何形式的破坏或网络攻击。”
里贝拉补充道，“显然，我们正在极其谨慎地开展工作，并将继续调查，以确定导致此次事件的具体原因。这是欧洲长期以来记录到的最严重的事件之一。”
西班牙和葡萄牙拥有高度一体化的电网，如同一个能源岛，并通过与法国的少量跨境互联线路与欧洲其他地区相连。
多年来，欧盟委员会一直呼吁加强各国能源系统的整合，尽管马德里、里斯本和巴黎三国均已多次表示愿意推进该计划，但进展却十分缓慢。
葡萄牙的E-Redes运营商表示，此次停电是由于“欧洲电网出现问题”，停电后收集的数据显示，电压不平衡是导致停电的原因。
Spain and Portugal lost power Monday in a massive electricity blackout that affected public transport systems, traffic lights, hospitals, manufacturing and nuclear power plants.
Outages were reported from Madrid to Lisbon, with large parts of the Iberian Peninsula without power as of early Monday afternoon.
The blackout was caused by a “very strong oscillation in the electrical network” that led Spain’s power system to “disconnect from the European system, and the collapse of the Iberian electricity network at 12:38,” said Eduardo Prieto, director of Spanish transmission system operator Red Eléctrica.
Prieto refused to speculate as to what had caused the power surge and declined to say if a cyberattack could have contributed to the blackout. While the flow of electricity has been reestablished in some parts of Spain, he added that it would take between six and 10 hours to have service fully restored throughout the rest of the country.
“At the moment there is nothing that allows us to say that there is any kind of sabotage or cyberattack,” said European Commission Executive Vice President Teresa Ribera, a former top minister in the Spanish government.
“And obviously we are working with the utmost caution and we will have to continue investigating to determine what are the specific causes that have generated this incident, which is one of the most serious that have been recorded in Europe for a long time,” Ribera added.
Spain and Portugal have a highly integrated energy grid that operates as an energy island and is linked to the rest of Europe through a small number of cross-border interconnections with France.
The European Commission has for years called for greater integration of the countries’ energy systems, but while Madrid, Lisbon and Paris have repeatedly signaled their will to move forward with that plan, advances have been slow to come.
Portugal’s E-Redes operator said the blackout was due to a “problem in the European power grid” and that data collected following the blackout suggested a voltage imbalance was responsible for the collapse.
