🗞️ Driving the news: A rare atmospheric phenomenon triggered a massive power outage across Spain and Portugal, disrupting transportation, communications, and public services
• Portuguese and Spanish grid operators cite "extreme temperature variations" leading to high-voltage line oscillations, although investigations continue
• European leaders ruled out cyberattacks and activated coordination efforts to restore stability.

🔭 The context: The Iberian Peninsula’s electricity grids are highly interconnected with the wider European network, making them vulnerable to external shocks
• This blackout comes amid rising concerns about grid resilience during extreme weather events, particularly as climate change drives temperature volatility
• The situation highlights the cascading risks from physical disruptions to critical infrastructure

🌍 Why it matters for the planet: Extreme weather-linked disruptions underline the urgency of strengthening grid infrastructure against climate risks
• As nations expand renewable energy use, grid flexibility and resilience become pivotal for sustainable energy security
• Failures like these also emphasize the importance of cross-border coordination in a decarbonized but increasingly interdependent energy system

⏭️ What's next: Spanish Prime Minister Pedro Sánchez convened a national security meeting, while the European Commission maintains close contact with both national governments
• Full restoration of Portugal’s grid could take up to a week, while Spain’s grid operator estimates partial recovery within 6–10 hours
• Authorities are expected to conduct a technical review to assess vulnerabilities and recommend upgrades for greater future resilience

💬 One quote: "There are no indications that today’s power outage has been caused by a cyber attack," — Antonio Costa, President of the European Council
