🗞️ Driving the news: Spain’s national grid operator Red Eléctrica (see sustainability performance) has ruled out a cyberattack as the cause of Monday’s widespread power outage that affected millions across Spain and Portugal
• Preliminary investigations indicate no evidence of intrusion in the control systems of the electricity grid, countering early public speculation and warnings from some local officials

🔭 The context: The blackout, described as caused by a “very strong oscillation in the electrical network,” remains under investigation, with the precise trigger still unidentified
• The incident prompted immediate concerns about cybersecurity, particularly given heightened sensitivities around critical infrastructure protection across Europe
• Authorities, including the European Commission, had urged caution, stressing the lack of evidence linking the event to malicious cyber activity

🌍 Why it matters for the planet: Grid resilience is critical not only for economic stability but also for the reliable integration of renewable energy systems
• As Europe rapidly scales up electrification and transitions to decentralized clean energy sources, ensuring the security and stability of grid infrastructure is vital to prevent disruptions that could undermine public trust and climate targets

⏭️ What's next: Further technical assessments are underway to determine the root cause of the grid oscillation
• Restoration efforts have succeeded in re-establishing power to 99% of affected users
• The event is likely to prompt renewed policy discussions on improving grid robustness, cross-border coordination, and early warning systems, particularly in the context of the EU’s growing digital and energy interdependencies

💬 One quote: “With the analyses we have been able to carry out so far, we can rule out a cybersecurity incident,” — Eduardo Prieto, head of system operation services at Red Eléctrica

📈 One stat: 99% of Spain’s power supply was restored within 24 hours of the blackout, according to national authorities
