Closing summary
… and on that note, it’s a wrap from me, Jakub Krupa, for today.
Energy supplies in Spain and Portugal are back to almost normal after one of the largest power cuts in recent European history, with some knock on effects still felt by residents, particularly in transport.
Spanish and Portuguese authorities vowed to do whatever it takes to prevent similar outages in future as they confirmed plans for domestic and international groups to look at the causes of the disruption (13:52, 15:34).
Spain’s highest criminal cause will also look at the power cut, investigating it “an act of computer sabotage” could have been perpetrated “against critical Spanish infrastructure” (14:44) – despite comments from grid operators that they ruled out a cyber-attack (11:51, 13:01).
Portuguese power network operator REN also denied it was behind a message circulated on social media attributing the massive blackout across the Iberian peninsula to a rare atmospheric event (12:16), a theory also rejected by Spain’s national meteorological office (11:23).
EU said it would look at what comes out of national investigations and “draw lessons” at the European level, reiterating its guidance to step up civil preparedness for all sorts of possible incidents (13:17).

Portugal to ask EU body to help with independent probe into blackout
Portuguese acting prime minister Luís Montenegro said his government had requested that the European Union’s Agency for the Cooperation of Energy Regulators perform an independent audit of the power outage that hit the Iberian Peninsula the day before, Reuters reported.
“We want a full investigation of the outage’s causes. We need quick, urgent answers,” Montenegro told a news briefing.
Montenegro also said the government would set up an independent technical committee to investigate the power cut, Público reported.
Spanish criminal court to probe 'computer sabotage' behind blackout
Spain’s highest criminal court, the Audiencia Nacional, has opened an investigation to determine whether “an act of computer sabotage” could have been perpetrated “against critical Spanish infrastructure”.
Announcing the investigation, a judge at the court said “cyberterrorism was among the possible explanations” for the blackout.

Spain 'overcoming worst,' focus on identifying causes, reforms to avoid future problems, prime minister says
Spanish prime minister Pedro Sánchez said that the country was “overcoming the worst” with most systems back up and running as he said that a similar incident must not be allowed to happen again.
He said that the investigations as to the causes of the blackout were ongoing, as he promised to get to the bottom of the outage and to implement necessary reforms to prevent it in the future.
The government has set up a commission to investigate the incident, he said, and will also look at the role of private energy companies.
Reuters reported that Sánchez also ruled out he possibility that an excess of electricity generated by renewable sources caused the outage.
EU to consider lessons learned from Spanish, Portuguese outage
The EU “will be looking into the lessons learned” from the blackout in Spain and Portugal to prevent a similar outage elsewhere in Europe, an EU spokesperson said.
Speaking at the daily press briefing, the European Commission chief spokesperson Paula Pinho said the cut was “of un precedented magnitude” and assured that the bloc will “obviously draw the necessary conclusions, and share them, and, if necessary, take the necessary action.”
“We look very closely into what were the reasons, how well were we prepared, and what are the lessons that can be drawn from such an incident. This will definitely keep all these actors busy in the coming days and weeks,” she said.
Pinho said the EU was still awaiting full assessment by Spain as to the causes, as she declined to comment on speculations whether the use of renewable power could contribute to the outage.
Pinho also called out mis- and disinformation circulating online yesterday, including an article featuring a made-up quote falsely attributed to commission president, Ursula von der Leyen.
Separately, commission spokesperson on preparedness, Eva Hrncirova, added that the Spanish and Portuguese operators are “well experience in handling high volumes of renewables in their electricity system.”
Hrncirova was also asked about the EU’s recent call for Europeans to step up their preparations for any disruptions, as she said “it applies to many situations in life, being prepared is better than being badly surprised.”
Portugal rules out cybersecurity as cause of blackout
Portugal’s government on ruled out a cyber-attack as the cause of a sweeping blackout across the Iberian Peninsula the previous day, after Spain’s grid operator said it reached the same conclusion, AFP reported.
“In Portugal, we have no information related to a cyber-attack or a hostile act at this stage,” said government spokesperson Antonio Leitao Amaro, telling CNN Portugal: “There would seem to have been an issue in the power transmission network” in Spain.
Early timeline of power cut from Spanish operator
Spanish grid operator Red Eléctrica’s operations executive Eduardo Prieto said two consecutive events, which took place at 12.32pm on Monday and then a second-and-a-half later, pointed to a “generation disconnection” that had cut off the supply across the peninsula.
While the system weathered the first event, it could not cope with the second. Prieto said the problem had originated in southwest Spain, which is where much of the country’s solar energy is generated.
Portuguese operator denies blaming outage on 'rare atmospheric event'
Portuguese power network operator REN denied on Tuesday it was behind a message circulated on social media attributing the massive blackout across the Iberian peninsula to a rare atmospheric event, AFP reported.
“REN confirms we did not put out this statement,” spokesperson Bruno Silva told AFP, without giving further details.
No evidence to suggest intrusion into operator's control system
Speaking on Tuesday morning, the operator’s head of services, Eduardo Prieto, said that preliminary investigations meant “we can rule out a cybersecurity incident”.
Prieto added that there was nothing to suggest “there was any kind of intrusion into the Red Eléctric control system”.
Power cut not caused by cybersecurity incident, Spanish grid operator says
Spanish grid operator Red Eléctrica has preliminarily concluded that the power cut was not caused by a cybersecurity incident, the El País newspaper and the EFE news agency reported.
'No unusual phenomena,' Spanish met office dismisses possible explanation of outage
Spain’s national meteorological office, Aemet, appeared to rule out the weather as a culprit.
“During the day of 28 April, no unusual meteorological or atmospheric phenomena were detected, and nor were there sudden variations in the temperature in our network of meteorological stations,” said Aemet.
This post was amended on 11:12 BST to remove a reference to earlier reports on potential causes of the power cut.

Power cut originated outside Portugal, minister says
Portuguese infrastructure minister Miguel Pinto Luz has once again suggested that the power cut originated outside Portugal, as the search for answers continues, Diário de Notícias reported.
Lisbon metro appears to be back up and running.

Spanish self-employed count losses after outage
The Spanish self-employed could have lost up to €1.3bn as a result of yesterday’s power cut, the Asociación de Trabajadores Autónomos estimated.
In a report carried by the Spanish news agency EFE, the group said that “today is still a difficult day” with some reporting connectivity and transport issues.
It said the biggest impact was felt in the hospitality and retail sectors.
Updated
Portuguese media are reporting that the Lisbon Metro was still down earlier today as the country reels off yesterday’s blackout.
Service is expected to be gradually resuming throughout the morning with first lines expected to be back up by now, but the status update monitoring tool on their website does not seem to be working.
Updated
Spanish prime minister Pedro Sánchez said this morning that 99.95% of energy demand has been restored in Spain, with 100% of substations back operational, as he headed for another meeting of the national security council.
“Thank you to all citizens for once again being an example of responsibility and civic spirit,” he said.
The Portuguese government is also expected to meet later this morning. It earlier issues a short social media update confirming the return of largely normal operations.
Morning opening: How did it happen?
Lights flickered back to life across most of Spain and Portugal after a massive blackout hit the Iberian peninsula, stranding passengers in trains and elevators while millions lost phone and internet coverage.
As of Tuesday morning, both Spain and Portugal reported power supplies almost back to normal with the network stabilised after the largest power cut in Europe’s recent history.
On Monday night, many went to bed in darkness, while others posted videos online celebrating the gradual return of power after many hours off-grid.
But for a continent so willing to talk up its efforts on energy security – with many leaders attending a high-level summit on this only last week – there will be many persistent questions that need urgent answers.
How do you so easily get a blackout affecting some 60 million people? What caused it? And, crucially, can it be prevented from happening at this – or larger – scale ever again?
Many will also study the mis- and disinformation on the causes or the culprits behind the blackout that managed to get traction during the blackout, with both Spanish and Portuguese governments forced to issue direct warning against speculations and reports online.
Despite the energy back on this morning, the disruption is likely to remain for a bit longer, as trains and planes are out of position and other processes are disrupted.
I will bring you all the latest.
It’s Tuesday, 29 April 2025, it’s Jakub Krupa here, and this is Europe Live.
Good morning.
