The Spanish government has launched an investigation into the significant power outage that left nearly the entire Iberian Peninsula without electricity on April twenty-eighth. According to the Ministry for Ecological Transition, the investigation is expected to take between three to six months to determine the cause of the blackout. The European Commission is also investigating and will provide its conclusions in a similar time frame.

The popular opposition party, the PP, has raised the issue of extending nuclear energy use, arguing that dismantling nuclear power without a reliable alternative poses risks to energy supply. Various political parties are divided on this topic, and debates will continue in Congress. The PP has focused its criticism on the government’s handling of the outage.

Minister for Ecological Transition, Sara Aagesen, emphasised the need to separate discussions about the blackout from those about nuclear energy closures. Aagesen reiterated the timeline for nuclear decommissioning, which will start in two thousand twenty-seven and conclude by two thousand thirty-five.

Significantly, the government has not ruled out any causes for the outage, including the potential for a cyber attack, despite earlier assertions by Red Eléctrica dismissing this theory. The government is utilising its top cybersecurity experts to ensure a comprehensive investigation.
