Widespread power outages hit several countries in Western Europe this afternoon, triggering chaos as rail networks, traffic lights and communications networks went down.
The shocking blackouts, which struck around 12.15pm CEST have impacted millions of people with almost all of Spain and Portugal affected.
Parts of France, Andorra and Belgium also suffered outages, according to the most recent reports.
Several metro and rail passengers were reportedly stranded in Madrid and Lisbon, while the international airports of both capital cities and several other airports across Spain and Portugal were closed.
Spain’s state electricity network operator Red Electrica said on X it had begun to restore power in the north and south of Spain, adding it may take some time to bring the whole grid back online.
Some critics have claimed that Spain’s integration of renewable energy sources into the European power network could have triggered the blackout, though the cause has not yet been established.
Renewable energy sources – wind, hydro and solar power – met the electricity demand for all of Spain for the first time ever on April 16, according to Red Electrica, which says it is leading an ‘ecological transition’ in Spain’s energy sector.
Other theories include a cyber attack, as analysts pointed out that Europe’s energy grid has suffered a substantial increase in cyber attacks following Russia’s full-scale invasion of Ukraine in February 2022.
Meanwhile, a fire in southern France is reported to have damaged a high-voltage powerline between Perpignan and Narbonne, which may also have contributed to the outages, according to Portugal’s national electric company REN.
Red Electrica is now working with two of Spain’s largest electric companies, Endesa and Iberdrola, to investigate the cause of the outages.
