Spain's top officials are in crisis mode following a nationwide blackout that left millions without power for up to 18 hours. The outage, which disrupted life all across the Iberian Peninsula, prompted an emergency meeting on Wednesday morning involving key members of the Spanish National Security Council, including Prime Minister Pedro Sánchez. The meeting aimed to clarify the source of the electricity failure that began on Monday afternoon.

With pressure mountings for answers, the Spanish government has sought assistance from various European regulatory bodies and local agencies. As part of the response effort, the National Security Council convened at 9 a.m. local time to discuss the implications of the blackout, with Sánchez and other senior officials expected to present findings on the grid's malfunctions.

The blackout halted significant activities and raised concerns regarding the reliability of Spain's national grid, especially after a noted shift towards renewable energy sources. In response to the crisis, Sánchez announced the formation of a commission led by the Ministry for the Ecological Transition to delve into the circumstances surrounding the outage.

Despite reassurances from Red Eléctrica, Spain's grid operator, about the lack of evidence pointing to a cyberattack, a judge has mandated that a thorough investigation be conducted over the next ten days. This will include reviews from both the intelligence service and law enforcement to rule out any malicious actions.

Furthermore, the National Cryptologic Center is assessing possible cyber threats that may have contributed to the emergency, with officials examining operational data from Red Eléctrica and private sector entities in the interests of leaving no stone unturned.

As power was restored, Spain's Interior Ministry began winding down emergency protocols, adjusting many regions from the highest alert level to a medium status to facilitate regional governance. However, Madrid and Extremadura are still under the highest alert due to their respective situations, indicating ongoing concerns in these regions.

Meanwhile, citizens remain anxious as the government scrambles to address the root causes of what has turned into a significant crisis.
